NPR Sunday Puzzle (Dec 28): Last NPR Puzzle of 2008

NPR Sunday Puzzle (Dec 28): Last NPR Puzzle of 2008:
Q: Take the phrase 'counting down the days.' Remove four letters from this phrase and rearrange the remaining letters to spell an appropriate number. What is it?
No need for hints... just take the letters and mix 'em up. You'll easily figure out which letters aren't part of the number.

Edit: My hidden clue was "mix 'em" which when swapped comes out as 'em mix, or simply the roman numeral MMIX.
A: Obviously the intended answer was TWO THOUSAND NINE in honor of the upcoming year. (9002 works too, but doesn't match with the "appropriate number" clue.)

NPR Sunday Puzzle (Dec 21): What?! Same Puzzle as Last Week?

NPR Sunday Puzzle (Dec 21): What?! Same Puzzle as Last Week?
Q: Name two things Santa Claus carries. Put them together, reading one after the other, and you'll name a musical instrument. What musical instrument is it?
Currently the NPR website has last week's puzzle repeated as this week's puzzle. The real puzzle can be heard if you click "listen now". Guess what? It's another musical instrument puzzle. It might be a little easier to play Christmas carols on this week's instrument, but I haven't heard any. I can't think of any other good hints that don't give things away immediately, so I'll just remind everyone to be as good as possible if people expect a visit from St. Nick.

Edit: The hidden clue was in the last phrase:
"...Be As Good (as) Possible If People Expect..."

NPR Sunday Puzzle (Dec 14): Need a List of Musical Instruments?

NPR Sunday Puzzle (Dec 14): Need a List of Musical Instruments?:
Q: Name a musical instrument, change the third letter to a different letter and double the last letter. The result will name a famous singer, in two words. Who is the singer and what is the instrument?
First, here's a list of musical instruments courtesy of Wikipedia. I had to see it a couple of times before I found the answer. Hint, if you are young you may not know this singer... go ask your Mom or Dad.

Edit: My first hint was that the list contained the instrument, but as a singular noun. The second hint was to "The Mamas and the Papas".

NPR Sunday Puzzle (Dec 7): Rhyme Time

NPR Sunday Puzzle (Dec 7): Rhyme Time
Q: The words "chic" and "squeak" rhyme with each other, even though they have no letters in common. Think of three words containing a total of 12 or more letters that rhyme and have no letters in common. The words must be common, uncapitalized words, and each will have just one syllable.
I have an answer that is 3 words, 4 letters each, but I'm not sure it is the intended answer. I expecially like one of the words (3rd alphabetically), but I'm questioning the second word. Everyone's heard of it but I don't know if it follows all the rules. For anyone that is searching, I think a rhyming dictionary might be the key to solving this. Also, it's important to note that chic has repeated letters, so that doesn't seem to be disallowed, as long as the words don't share common letters.

Edit: Initially I was thinking of KNEE, QUAY, PRIX, but my dictionary doesn't like prix except in grand prix and prix fixe.
SKI, QUAY (pronounced like 'key'), THREE
There are other possible choices like:
pooh, screw, gnu (or flu)

NPR Sunday Puzzle (Nov 30): All Points Bulletin...

NPR Sunday Puzzle (Nov 30): All Points Bulletin...:
Q: Think of the name of a lawbreaker that starts with S. Remove the S and one other letter, and the remaining letters, in order, will name another lawbreaker.
Not to sound confident, but I'm positive I have the right answer. Note: when I first heard the puzzle, I was thinking they might want the *names* of specific criminals (e.g. Jesse James). If you made that mistake you will find yourself struggling with this puzzle. :-)

Edit: Not to sound smug, but I know the intended answer. An alternate answer that was submitted by some was "stalker --> taker"

NPR Sunday Puzzle (Nov 23): Famous Singer Anagram

NPR Sunday Puzzle (Nov 23): Famous Singer Anagram:
Q: Name a famous singer from the past who has five letters in his or her first name and six letters in the last. Rearrange the letters of the last name, plus the last letter of the first name (seven letters in all) to name a place where this singer famously performed. Who is the singer and what is the place?
In the comments from last week, Natasha says this is easy. I've obviously been overthinking it then.

Edit: I was less familiar with this singer so it took longer to get the answer. There were some good clues in the comments, including "alas, I am, Carl" which was an anagram of the singer's full name and uses of the word "callous".
A: Maria Callas --> La Scala

NPR Sunday Puzzle (Nov 16): Authors Beginning with C

NPR Sunday Puzzle (Nov 16): Authors Beginning with C:
Q: Name a famous author whose last name starts with the letter C. Cross out four letters in it. The remaining letters, in order, will name another famous author also starting with C. Who are these two writers?
I'm not sure if I have the intended answer but I have a pair of authors that will work... it helps if you have a list of authors starting with C

Edit: It's after the deadline, so I'm going to reveal what I think is the intended answer.
A: Miguel de CERVANTES (famous for "Don Quixote")
(cross out e,v,t,s)
Stephen CRANE (famous for "Red Badge of Courage")

NPR Sunday Puzzle (Nov 9): A Pair of Animals, Running Wild in the Capital!

NPR Sunday Puzzle (Nov 9): A Pair of Animals, Running Wild in the Capital!:
Q: Take the names of two animals. Drop the third letter from each name. Read the remaining letters, in order, from left to right and you'll name a world capital. What is it?
There are several ways to approach solving this puzzle. You could look at lists of animals, or perhaps it might be easier to look at a list of world capitals. I don't think you'll find it too difficult. Oh, my clue this week is that "tiger" is not one of the animals. Does that help?

Edit: My clues were "Oh my" and "tigers". At least my clues were less obvious than some posted in the comments section. I had to delete one that had the outright answer. Please wait until after the Thu. 3pm ET deadline to post spoilers.
A: BEaR + LIoN --> BERLIN (Germany)

NPR Sunday Puzzle (Nov 2): Setting the Clock Back

NPR Sunday Puzzle (Nov 2): Setting the Clock Back:
Q: The names of presidents Ronald Reagan and Bill Clinton have something unusual in common. In fact, these are the only presidents in U.S. history whose names share this characteristic. What is it?
I was in the middle of setting my clocks back this morning so didn't hear the puzzle. Is anything missing from what I wrote?

Edit: It's now after the deadline so I can reveal my hints. The key words were "middle" and "missing". Also, the reference to setting the clock back was a hint to think back to prior presidents.
A: Ronald Wilson Reagan and William Jefferson Clinton -- their middle names are the last names of former U.S. presidents

NPR Sunday Puzzle (Oct 26): Has Anyone Heard of This Sports Team?

NPR Sunday Puzzle (Oct 26): Has Anyone Heard of This Sports Team?:
Q: 'Nonclassical analysis' contains eight different letters. Two of them occur once, two of them occur twice, two of them occur three times, and two of them occur four times each. Which sports team's name has this same property?
Oh brother. Couldn't Will Shortz have picked something more topical for this week's puzzle rather than hitting us with this week's stumper? I doubt you could scour the sports pages and find any mention of this team... right? I mean, people are busy with Halloween but this puzzle has nothing to do with a favorite fall activity. Well, I'm sure you'll eventually figure this out, maybe after 5 tries... unless you have to take a couple more guesses.

Edit: Clues -- "Oh brother" (as in City of Brotherly Love), "hitting", "favorite fall activity", and "out". Plus there were additional references to the World Series throughout.

NPR Sunday Puzzle (Oct 19): Now That's A Capital Idea

Sunday Puzzle (Oct 19): Now That's A Capital Idea:
Q: Name a famous actress with four letters in her first name and five letters in her last name. Drop the last letter of her first name and the last two letters of her last name. The remaining letters, in order, will name well-known a world capital. Who is the actress and what is the capital?
Seems like we have a pattern going on. A few weeks ago the puzzle answer was "Giant Anteater" and I gave the clue to "B.C. Comics" which has a giant anteater as a recurring character. Then I used the same clue to hint at Bill Cosby for the puzzle on "Jello". Perhaps I can reuse an old clue in a similar fashion for this week?

Edit: The hint was a reference to the Cosby show. The actress in question played Denise Huxtable

NPR Sunday Puzzle (Oct 12): A Series of *Fortunate* Events...

NPR Sunday Puzzle (Oct 12): A Series of *Fortunate* Events...:
Q: Name the sixth thing in a well-known series. Change its third letter to the next letter of the alphabet. Then rearrange all the letters and you'll get the seventh thing in the series. What names are these?
If you've solved this, then about the only thing left to do is to debate the pronunciation of the seventh item, or to say how many items are really in the list. I'll just say, that the third item is my favorite.

Edit: If you hadn't figured it out, the well-known series consists of the names of the planets.
A: SATURN --> -T +U --> URANUS

Suduro - A blend of Sud(oku) and (Kak)uro

Suduro -- If you already know and enjoy Sudoku and/or Kakuro, there's a website that offers a blend of the two. The grid is filled like a normal Sudoku, but there are gray squares that are filled similar to Kakuro. Sums are provided for just the gray squares in each row or column. In addition, a separate box contains the sum of just the gray squares in each 3x3 square. The extra dimension of clues should make for some fun puzzles. Give it a try.Suduro Example

NPR Sunday Puzzle (Oct 5): Anagram Interaction:
Q: Rearrange the 11 letters of 'interaction' to make two closely related words. What words are they?
I seem to be in the habit of pretending I don't have a clue, when I really do. Is this week any different?

Edit: The hidden clue was "habit"

NPR Sunday Puzzle (Sep 28): Just Desserts:
Q: Name a popular dessert that has two syllables, in which the vowel sound in the first syllable is a short E. Change this to a long A, and phonetically you'll name a famous singer. Who is it?
I liked my clue from a couple weeks ago regarding the B.C. Comic. I wish I had a similar clue this week. Oh wait, maybe I do...

Edit: My clue above was to the comedian Bill Cosby and he is associated with this dessert.
A: JELLO --> J. LO (Jennifer Lopez)

Friday Fun - Mini-Sudoku Puzzle (nine squares!)

Mini-Sudoku (nine squares!)For all of those that are tired of having to fill in a full Sudoku grid, here's a Mini-Sudoku Puzzle. The goal is to fill the nine squares with just the digits 1 to 9. The only hints provided are the "L-block" hints at each corner. Each value tells you the sum of the five squares that make up the two adjacent edges.

Note: This is not a magic square. You cannot make any assumptions about the totals of the rows, columns or diagonals.

See how quickly you can come up with the unique solution. I'll probably post the answer next Friday. In the meantime, please don't reveal the answer so others can enjoy the puzzle too. Post comments on whether you find this puzzle easy, hard, fun or frustrating. I'd be interested in your solving techniques and times, too.

NPR Sunday Puzzle (Sep 21): Opposites Attract

NPR Sunday Puzzle (Sep 21): Opposites Attract:
Q: Take a common two-word phrase with four letters in each word. Each word has a single O as its vowel. If you add an R somewhere in the second word, the two words become opposites. What is the phrase?
Well at least Will is leaning toward puzzles that take more than 30 seconds to solve...the last one took several days for some people. Your solving time will be quicker if you remember the words are opposites once you add the 'R' (I started searching for synonyms.) Don't give away the answer before the Thursday deadline, but feel to take a shot at posting some "hints".

Edit: My hints weren't very good, but there were some references to Will (Shortz), length of time (long and short), and the obvious inclusion of the word "shot".

NPR Sunday Puzzle (Sep 14): Name that Animal

NPR Sunday Puzzle (Sep 14): Name that Animal:
Q: Take the phrases 'move over' and 'local call.' In each case, the last three letters of the first word are the first three letters in the next. Name a familiar animal, in two words, in which the last three letters of the first word are the first three letters of the next. Hints: It's a furry, four-footed animal that can grow up to six feet in length. The first word in its name has five letters, the second word has eight.
We seem to have the question early this week from the RSS feed. My daughter, in kindergarten, knew the answer to this. Her class has been studying animals. If she can get this, so can you! Incidentally, some sources I checked said they could grow to be 8 feet in length... that's large! Zot!

Edit: There were several clues above. In kindergarten you learn your ABCs... that was a hint to think of animals at the beginning of the alphabet. Also, if anyone is familiar with the comic strip B.C., you should know what Zot refers to.

NPR Sunday Puzzle (Sep 7): You'll Figure it out in the End

NPR Sunday Puzzle (Sep 7): You'll Figure it out in the End:
Q: Kris Kristofferson's last name starts with his four-letter first name. Can you name a famous American whose last name ends with his four-letter first name? Hint: The last name has seven letters.
Note: It is easy to overlook that the last name ends with the letters in his first name, so rather than MARK MARKHAM, you should be looking for names like MARK WIDMARK (not the answer).

Edit: Check the comments for clues like "jump" and "wicked" (homonym for "evil" = "evel")
A: Motorcycle Daredevil EVEL KNIEVEL

NPR Sunday Puzzle (Aug 31): Labor Weekend Sale, Vowels Are $100, Three Days Only

NPR Sunday Puzzle (Aug 31): Labor Weekend Sale, Vowels Are $100, Three Days Only:
Q: Think of a 9-letter word with no repeated letters. The letters in the odd positions (the 1st, 3rd, 5th, 7th and 9th positions) are vowels. All five vowels, A, E, I, O and U, appear once each in some order. What word is this?
When I first read the puzzle, I thought "I already know the answer". It's the word FACETIOUS with A-E-I-O-U appearing once and in order... After I had that in my mind, for awhile it prevented me from noticing that I hadn't solved the right puzzle.

I think others might be stymied by the fact that the correct answer is a word that people commonly misspell. Hopefully you aren't one of the people that suffers from such an inability to spell. P.S. I was able to come up with two answers, but the second is not a common word at all. I wonder if anyone will submit it?

Edit: It's after the deadline so I think it okay to reveal my hidden clues: "prevented" and "suffer from".

NPR Sunday Puzzle (Aug 24): CH-CH-CH-CH-CHanges

NPR Sunday Puzzle (Aug 24): CH-CH-CH-CH-CHanges:
Q: Think of a person's job title that contains the consecutive letters C-H. Move the C-H to the front, then take what used to be the first letter and put it where the C-H was. The result will be another person whom the first person tries to catch. What words are these?
Hmm... another "less than satisfactory" puzzle. The answer came to me right away as I'm sure it has for others. Personally, I don't think the words are really such a pair, and the pairing is rather contrived. I'd give you more hints, but I don't think it would be fair to those that figured out on their own.

Edit: I don't think it was a coincidence that school starts around this time...

NPR Sunday Puzzle (Aug 17): U.S. Postal Abbreviation Quiz

NPR Sunday Puzzle (Aug 17): U.S. Postal Abbreviation Quiz:
Q: Take the two-letter postal abbreviations for three U.S. states. Add the letter A. Then add the two-letter postal abbreviations from three more states. You'll have 13 letters in all. Reading from left to right, you'll get a familiar three-word phrase that's seen on many products. (Hint: The three words in the answer phrase have four, two and seven letters respectively.) What's the phrase?
The puzzle is rather U.S.-centric. If you aren't familiar with the codes, here is a list of U.S. Postal Abbreviations. There are so many clues in the question itself that you shouldn't have any problem solving this. P.S. If you haven't seen this exact phrase recently, you might have at least seen ones similar to it.

Edit: Let's see how many submissions there are on this one... I thought it was pretty obvious.
Massachusetts (MA)
Delaware (DE)
Indiana (IN)
Maine (ME)
Rhode Island (RI)
California (CA)

NPR Sunday Puzzle (Aug 10): Product Playtime:
Q: Think of a familiar brand name ending in the letters G-S. Change the G-S to an O and you'll get the brand name of a different product. What is it? Hint: The first word has five letters, and the second has four.
I had more familiarity with the second term so I solved it backwards. My wife had no problem solving it forward.

Edit: Both of us had this as soon as we finished reading the question. Hopefully you found it as simple.

Q: Start with an eight-letter mathematics term. Remove the first, fourth and eighth letters to produce a synonym of the original word. What is it?
A small percentage of the population might struggle on this, but I think most will find this puzzle relatively easy.

Edit: I was probably too obvious with the hints which included obvious synonyms of the answers. Check the comments for other hints that were provided.

Friday Fun - Cycling on the Bridge

Cycling on the BridgeTwo bicyclists start cycling from opposite ends of a bridge. One cyclist is faster than the other and they meet at a point 2,000 feet from the nearest end. When each cyclist reaches the opposite end of the bridge, he takes a 15 minute rest break and then starts on his on return trip. The cyclists again meet 720 feet from the other end. Assuming each is cycling at a constant speed, how long is the bridge?

Note: There is no mention of the actual speed of each cyclist, or the time that each takes but this problem is solvable. In fact, there is an elegant solution that could be understood by an elementary school student, with basic rules of addition and subtraction. It can also be solved the "hard" way. I'll post the elegant solution next week.

Edit: I've provided an answer in the comments.

NPR Sunday Puzzle (Jul 27): Egomaniac Anagram

NPR Sunday Puzzle (Jul 27): Egomaniac Anagram:
Q: Re-arrange the letters in the word 'egomaniac' to spell a sign seen in many stores. What is it?
Well we have returned home from Iceland safely. One thing I will say, is if you try and pronounce the place names, you'll find most Icelanders replying, "what did you say?". A pronounciation hint -- the town of "Höfn" sounds like a hiccup. The 'fn' is pronounced 'b' so don't say "Hoffin", say "Hub" as you inhale quickly. As for the puzzle, it's so easy, you can solve it faster than you can say, Kirkjubæjarklaustur (trust me, don't try...).

Edit: There were a couple hints above -- returning to a place, and the phrase "What did you say?". I initially thought that there would be a gerund with "ing" so I pulled those letters aside. I then saw the word "come" in the remaining letters and knew the answer.

Friday Fun - How Long is the Ring Road around Iceland? - Answer

Iceland Ring RoadWe should be flying back home from Iceland about this time. Hopefully everyone has had fun with the puzzles while we have been gone. If you haven't had a chance to solve the puzzle about the Iceland Ring Road yet, take a look at last Friday's post and don't read any further. But if you want the answer, read on...
A: Let A be the speed of the first couple and B be the speed of the second couple. After an equivalent amount of time T, one couple has traveled AT miles and the other travels BT miles. For the return, the first couple now travels BT miles in 9 hours, while the other couple travels AT miles in 16 hours.

A = BT/9
B = AT/16

9A = BT
16B = AT

T = 9A/B
T = 16B/A
9A^2 = 16B^2
Take the square root of both sides (which is okay because both are positive)
3A = 4B

This tells us the ratio of their speeds is 4 to 3. In other words, over the same time, the faster couple will travel 4/7 of the ring road, the slower couple will travel 3/7. The difference is 120 miles. And if 1/7 is 120 miles, the whole road is 840 miles.

NPR Sunday Puzzle (Jul 20): Weekend Edition Sunday Puzzle

Well, this is an interesting post. I'm on vacation, so I'm actually still not around to be able to tell you what the puzzle is or to give you any hints.
Q: What is the answer to the puzzle on the NPR Website?
My wife and I should be in Akureyri in Northern Iceland at this point. We are planning on doing a whale-watching trip. I think we'll need to bundle up because it can get nippy out on the water watching whales frolick. If I'm lucky, that will be a fruitful clue to this week's puzzle and be central to solving it, but I doubt it. Help each other out, but don't give away the puzzle until after the dead line on Thursday 3pm ET.

Friday Fun - How Long is the Ring Road around Iceland?

Iceland Ring RoadMy wife and I are taking a leisurely drive around Iceland on the Ring Road... at this point we should be a little more than half way on the East side of Iceland in Egilsstaðir. However, I thought it might be fun to give you a little topical puzzle in honor of our trip.
Q: Two couples leave Reykjavik at exactly the same time traveling opposite directions on the Ring Road around Iceland. When they meet later, one couple has traveled 120 miles farther than the other. After a night's rest in a hotel and some refueling, the couples continue their respective drives. The first couple arrives back at Reykjavik 9 hours later, the second couple takes 16 hours. Assuming that each couple maintains the same constant speed each time they drive, how long is the Ring Road around Iceland?
I'll post the answer next Friday.

My wife and I are away in Iceland for a couple weeks taking in the sights. At this point we should be in Höfn toward the Southeast of Iceland as part of an 11-day driving tour of the country. However, I didn't want to leave everyone wondering about the answer to the puzzle so I've provided a scheduled post to appear after the deadline... here it is:

NPR Sunday Puzzle (Jul 13): Names from Early American History

NPR Sunday Puzzle (Jul 13): Names from Early American History:
Q: Name a famous person from early American history with five letters in the first name and five letters in the last. Six letters of the alphabet are used in this name, some of them repeated. These same six letters make up the name of another person in early American history whose first and last names have six and four letters, respectively. Who are these two people?
This wasn't too hard to figure out, but it might be helpful to have a list of names associated with early American history handy. Both names should be familiar to most people. One hint: don't assume that the names are exact anagrams of each other.

NPR Sunday Puzzle (Jul 6): Contaminated Anagram

NPR Sunday Puzzle (Jul 6): Contaminated Anagram:
Q: Take the word 'contaminated.' Rearrange the 12 letters to get a two-word phrase for a familiar sign.
For all of you that complained that last week's puzzle was too hard, here's one that is extremely easy. A few minutes anagramming the letters will net you the answer (or you can cheat and use an anagram program). Feel free to leave a comment with a hint, but remember you aren't allowed to give any spoilers before the deadline of Thursday 3pm ET.

P.S. The answer isn't "Tandem Action". :-)

Edit: My hidden clue was "you aren't allowed...". I also liked phredp's clue in his comment about "I can't enter..." and geri's comment about "Admit it..."

NPR Sunday Puzzle (Jun 29): Anyone have a Pencil?

NPR Sunday Puzzle (Jun 29): Anyone have a Pencil?:
Q: A man buys 20 pencils for 20 cents and gets three kinds of pencils in return. Some of the pencils cost 4 cents each, some are two for a penny and the rest are four for a penny. How many pencils of each type does the man get?
It's a rare NPR *math* puzzle. Using algebra you could write an equation for the number of pencils, and one for the cost of the pencils. But that results in two equations and three unknowns. Fortunately there are some constraints and a little trial and error will get you the answer. Note: You have to have at least one of each type, so just getting 4 of the first type and 16 of the last type wouldn't work.

Edit: I think the thing that confused most people was they assumed they had to buy 4 of the 1/4 cent pencils, or 2 of the 1/2 cent pencils. You can't make 20 cents with those constraints. Here's how I solved it.

Let A be the number of 4 cent pencils.
Let B be the number of 1/2 cent pencils.
Let C be the number of 1/4 cent pencils.

Number of pencils:
A + B + C = 20 pencils

Cost of pencils:
4A + B/2 + C/4 = 20 cents
Multiplying this second equation by 4 to remove the fractions we have:
16A + 2B + C = 80

Now subtract the first equation to eliminate one variable:
15A + B = 60

There are some obvious constraints on A. Because you need at least one of each type of pencil, none of the values can be 0. That eliminates A = 0 or A = 4. Trying the other values you get:
A = 1, B = 45 --> too many pencils
A = 2, B = 30 --> too many pencils
A = 3, B = 15 --> C = 2

3 pencils (at 4 cents) = 12 cents
15 pencils (at 1/2 cent) = 7 1/2 cents
2 pencils (at 1/4 cent) = 1/2 cent

NPR Sunday Puzzle (Jun 15): English Tea Anagram:
Q: Rearrange the letters of ENGLISH TEA to name a famous person with a prominent mustache — first and last. Who is it?
I had a couple thoughts when approaching this puzzle. I first thought that the person must have some relevance to today, being it is Father's Day. My second thought was that the person might have been in the news recently; Will Shortz often does that (for example Harrison Ford was the subject of a puzzle around the time Indiana Jones IV was being released). Well, I don't think either of these things apply... or do they?
My hints: The person is a man. And there is only one L and one T available in the letters, so don't misspell his name.

Edit: The main clue was "Today"... and there were lots of good clues in the comments about being "critical", mentions of "onions", etc.

NPR Sunday Puzzle (Jun 8): 5-Digit Sequence

NPR Sunday Puzzle (Jun 8): 5-Digit Sequence:
Q: A calculator displays a five-digit number. The first four digits are 8735. These digits form a logical sequence. What is the fifth number in the series?
I was led down the wrong path initially because I didn't read the puzzle carefully. There's an important clue in the question which you'll see if you are bright.

LED 7-segment displayEdit: The key to the puzzle was to realize that these digits were on a calculator. I mentioned that in my clue along with the additional hints of "LED", "see" and "bright". I mentioned the word "segment" in one of my comments too.
A: The next digit is also 5. Each digit is the number of LED/LCD segments that are lit in the prior digit.

NPR Sunday Puzzle (Jun 1): Movie Star Synonyms

NPR Sunday Puzzle (Jun 1): Movie Start Synonyms:
Q: Name a famous male movie star. Change the first letter of his first name to a G and change the last letter of his last name to a T. The result will be two words that are synonyms. Who is the movie star and what are the words?
The first time I tried to figure this out I was little lost, but at last, after 3 or 4 attempts, the answer was completely clear.

Edit: It was crystal clear...

NPR Sunday Puzzle (May 25): I.O.U. a clue

NPR Sunday Puzzle (May 25): I.O.U. a clue:
Q: The phrases 'part time' and 'time share' are familiar phrases with 'time' in them, and the adjoining words, 'part' and 'share,' are synonyms. Find two phrases that work similarly with the word 'child.' What are they?
Even with an extra day over the long weekend and I wasn't able to figure this one out yet. I have a couple answers where the words don't seem like strong synonyms, so I don't think either is the answer. One has 4 letter words for both parts. The other has words that start with the same letter. This week I'm hoping the commenters will come up with good clues in my place.
A: The accepted answers are up on the NPR website. Personally I have issues with all of them so I won't transcribe them here.

NPR Sunday Puzzle (May 18): Change One Letter in the Last Name

NPR Sunday Puzzle (May 18): Change One Letter in the Last Name:
Q: Think of a well-known person on TV who has eight letters in their first name and four letters in their last. The last name consists of: consonant, vowel, consonant, consonant. If you change the vowel in the last name to an 'a,' the result will be a word that is defined by the first name.
Good, we are getting back to challenging puzzles. Saying this person is a well-known person on TV is like saying Tiger Woods is a popular TV personality. Yes, he is on TV, but is he most well-known for being on TV? I had more luck working backwards on the puzzle.

Edit: Some of my clues were explicit (such as thinking of someone associated with TV, but known for something else.) There were a few "less obvious" clues (Tiger is an animal, luck rhymes with puck, back rhymes with pack).
Now read the comments and you'll see the creative hints that were left by others.

I'm sorry. My PC was having issues so I wasn't able to post a hint this weekend. The puzzle is easy, so I'm sure you'll figure it out.

Edit: My hints were PC (as in Gateway) and weekend (as in getaway)

I don't have a lot of time for a hint because we are busy! We are planning my son's birthday. With everything my wife has planned it should be grand. But I think we can do without the performer dressed like Tarzan.

Edit: The hints were all the words before the punctuation marks: BuSY (initial letters of the answers, in alphabetical order), Birthday (Bash), Grand (Slam) and Tarzan (Yell).

NPR Sunday Puzzle (Apr 13): A Quick Snack:
Q: Name some places where people eat, add one letter at the end of the word, and you'll get an adjective that may describe the places' food. What are the words?
I'm packing for a trip so this week's clue will be short. Both words in the puzzle answer leave me wanting more.

Edit: Apart from both words being shortened words (delis instead of delicatessens, delish instead of delicious), the word "delish" is hardly one that I see a lot in formal writing. It does appear in the dictionary however.

NPR Sunday Puzzle (Apr 6): I'm Fired:
Q: Think of a six-letter hyphenated word meaning 'eager.' Change the fourth and the sixth letters to get another hyphenated word meaning 'less than eager.' What are the words?
I was all excited because I figured out the puzzle. I even wrote a post with all the clues (I thought the answer was ON-EDGE --> ON-EGGS). I even "pulled the trigger" and posted it. I showed it to my wife and she told me I was all wrong. Hearing her answer, I realize I totally missed the target. Boy am I embarrassed! My new clue is the hyphen doesn't stay in the same spot.

Edit: I seems like most people finally figured this one out. Credit this week goes to my wife since she had to tell me the answer.

NPR Sunday Puzzle (Mar 30): Over and Out

NPR Sunday Puzzle (Mar 30): Over and Out:
Q: Think of an adjective starting with 'over.' What follows 'over' is a word that has a homophone — that is, a word that sounds the same but is spelled differently. For example, in 'overcast,' 'cast' is a homophone of 'caste.' Think of an adjective starting with 'over' that is frequently used with the homophone of the word that follows. What is it?
I'm a little confused this week. I see lots of choices that might work but I'm not sure I get what the puzzle is asking. For example you could argue that any of the following might work: overseas --> seize, oversight --> site, overrode --> road, overhaul --> hall, oversees --> seas, overheard --> herd, overflew --> flue, overlaps --> lapse, overdue --> do, overawed --> odd, etc. I have a potential answer (not listed here), but I'm not even happy with it and am ready to discard it.

Edit: The title (Over and Out) was obviously a clue and so was the sentence about being unhappy and discarding some(one). I submitted the answer below, but there is still a possibility it isn't the intended answer. At least phredp (see comments) seems to concur, so hopefully it is right.
A: OVERTHROWN --> THRONE, as in the monarchy (throne) was overthrown.

Billiard Balls Puzzle

Billiard ball puzzleIn the American game of "eight-ball" there are 15 numbered balls (1 through 15). At the beginning of the game, these balls are racked into a triangular pattern as shown.

The challenge this week is to place the numbers 1 through 15 into an upside-down triangle pattern such that each number is the result of *subtracting* the two numbers above it. To eliminate mirrored answers, provide a solution where the numbers at the three points of the triangle are in ascending order going clockwise.

P.S. When taking the difference, always use the absolute value. Feel free to add a comment with your answer, along with how you solved it.

Q: Using the middle row of letters on a keyboard, name something that has eight stars. Hint: The answer is spelled in 10 letters.
Let's see there were 7 castaways on Gilligan's Island, so that was 7 stars perhaps. Or on the Brady Bunch there were Mike and Carol and 6 kids but Alice made 9 stars. Perhaps I'm thinking of the wrong type of stars. What a folly!

Edit: My clue was "folly" as in Seward's Folly. If you want to see more clues, check out the comments. I liked the references to "Juneau" and "Alaska" as well as the hints for "flag".

A Puzzle for Leap Day, 2008 -- Can you make 97?

2008 = 97Today is February 29, a special date that only appears on our calendars every four years. There are exceptions to this 4 year rule on century years (those ending in 00). These years are NOT leap years unless the century is evenly divisible by 400. For example, 2000 was a leap year, but 2100 will NOT be. The cycle of leap years on our calendar repeats in a 400 year cycle. Within that cycle there will be 97 leap years.

All this historical information was a way to introduce this week's math puzzle.

Q: Using each of the digits in 2008 and standard math operations, can you write an expression that equals 97?
  • Each of the digits 2, 0, 0, 8 must be used. (2 and 8 will appear once, 0 will appear twice.)
  • You may use standard math operations of +, -, x, /, √(square root), ^(raise to a power) and !(factorial) along with parentheses for grouping.
  • Decimal points and multi-digit numbers may be used (e.g. 20, 208, .02 or 2.8
  • If squaring is done, that uses up the digit 2.
  • 0! is agreed to have a value of 1.
  • Anything raised to the zero power (i.e. x^0) is 1, but 0^0 may not be used (undefined)
  • The integer/floor/ceiling/round functions may NOT be used.
  • Change of bases may NOT be used.
  • Logarithms may NOT be used.
  • Sine and Cosine may NOT be used.
Edit: The answer is now available in the comments... but don't look if you still want to figure it out on your own.

NPR Sunday Puzzle (Feb 24): Uh-oh! Oops! Drat! Where is that darn city?:
Q: Take the name Seattle. The letters in the odd positions are S-A-T-E, which spell SATE. Think of another U.S. city name, in seven letters, in which the letters in the odd position spell a common four-letter exclamation. What's the city and what's the exclamation?
My wife had the answer right away but I was off thinking world cities, European capitals, etc. Once I got back to U.S. cities it came to me right away. Isn't L. L. Bean associated with this city? No? Oh well, maybe I'm wrong. Post your clues but don't reveal any answers until after the deadline (Thursday 3pm ET). Talk to you later!

Edit: We'll have to see what the official answer is from NPR. It might be Oshkosh, but I was thinking Chicago, home of the elevated transit system called the "L" and a new sculpture in Millennium Park entitled "Cloudgate", but known more familiarly as "The Bean".

Q: There's a seven-letter word for something that is a measure of wealth and power. The first four letters name an animal that is a symbol of power. And the last four letters name another animal that is a symbol of power. What's the word?
These simple word puzzles are getting old. There are so many clues in what Will provided again this week, that I'm 99.5% sure that most people will solve this almost immediately. If you say you spent more than an hour figuring this out, I'd call you on it and say you are lying.

Edit: This week's clues, "getting old", 99.5% (as in purity) --> Gold Bullion. Hopefully I don't have to explain the "bull" part of calling you on it. And lying sounds a lot like "lion".

Q: Name a city in six letters that's a popular tourist destination. Divide this name in half, move the first three letters to the end keeping everything else in order, you'll name some places where people like to relax. What are they?
When I think of tourist destinations, my first thought is they must include the sun as a primary reason for going. Think hot, hot, hot!

Edit: Hidden in my hint: "...include the sun as a primary...". The item in italics is an anagram of both answers. And the mention of heat applies to both as well.
A: NASSAU (capital of the Bahamas)--> SAUNAS

Create a foldable 3-D dodecahedron calendar

Dodecahedron CalendarI discovered a fascinating site a few years back and completely forgot about it. You've probably seen a 3-D calendar with each month on one of the faces of a dodecahedron. But have you ever wanted to print and construct your own? Ole Arntzen of Norway created a webpage that lets you pick a year, a language and a few other options and then it creates a printable template for a 12-sided calendar.

You can generate a ready-to-print PDF file, or an editable PostScript file. With a little editing of the PS file, you can add holidays, birthdays, school breaks, anniversaries, etc. Take a look!

Q: Name a sport that has only one vowel in it. Change the vowel to a different vowel. If you read the result backward, you'll get a piece of equipment used in that sport. What's the sport and the piece of equipment?
I've gone over looking for the answer to this week's puzzle. Of course it makes sense that the answers are both one syllable, but after trying for several hours now, my interest in solving the puzzle this week is waning.
Edit: Time to reveal my clues:
"gone over looking for", "Of course..." --> GOLF
"waning" = "flagging" --> FLAG

NPR Sunday Puzzle (Jan 26): A Puzzle for the Birds

NPR Sunday Puzzle (Jan 26): A Puzzle for the Birds:
Q: Take the three bird names egret, crane and owl. Rearrange the 13 letters to spell three other bird names. They are all common names. What are they?
You can solve this iteratively... look closely at the letters and find a bird name (say WREN), those letters, in turn, should lead you to another bird, then look at the remaining letters, etc.

Edit: Some of my clues were hidden in the comments. I mentioned having a 'sharp eye' or some would say 'eagle-eyed'. I also said that user 'Feed' should be proud of her answer, or some would say she has something to 'crow' about. And above I said, "those letters, in turn" which should lead you to 'tern'. Finally, my post ended etc which gives you the initial letters of each bird.

How about a math puzzle?

Number PuzzleIt has been awhile since I've posted any non-NPR puzzles. Here's one to make you think:
Q: A nine-digit number ABCDEFGHI is such that its digits are all distinct and non-zero. It has the following properties:
The two-digit number AB is divisible by 2,
the three-digit number ABC is divisible by 3,
the four-digit number ABCD is divisible by 4,
and so on until finally,
the nine-digit number ABCDEFGHI is divisible by 9.

What is this special nine-digit number?

NPR Sunday Puzzle (Jan 12): Tale of Two Authors

NPR Sunday Puzzle (Jan 12): Tale of Two Authors:
Q: Name a famous American novelist whose last name contains nine letters. Drop the first and last letters, and rearrange the remaining seven letters to name another famous American novelist. Who are these authors? Hint: The first novelist is male, and the second one is female.
If you look for a clue in my title, you'd be missing something obvious -- Charles Dickens is an English novelist, not American. Honestly you'd figure out more from the puzzle than from examining my title for a hidden clue. The one thing I will say is that both novelists were alive at the same time, though barely. Does that help?

Edit: The title was an obvious reference to "A Tale of Two Cities". The item that was missing was the letter 'A'. That was a rather obtuse clue to "The Scarlet Letter", a novel by the first author.
The other clue was hidden in "puzzle than from examining..."
"Ethan Frome" was a novel by the second author.
The 3rd clue just gave you more information to confirm your answer and might have given away that both authors were deceased.
Putting it all together:
(Nathaniel) HAWTHORNE (1804-1864)
(Edith) WHARTON (1862-1937)

NPR Sunday Puzzle (Jan 5): Happy New Year!

NPR Sunday Puzzle (Jan 5): Happy New Year!
Q: Take the phrase, Yeshiva Center, a place of Jewish studies, rearrange these 13 letters to name a well-known movie. It has three words in its name. What movie is it?
I've had a long-time yearning to come up with the ultimate clue to one of the puzzles... and sorry to say, all I have is a mediocre set of clues for this one. I don't have any wonderful insight into how to solve the puzzle. I just kept rearranging letters on the paper until I saw a couple words that were familiar. I suppose you could use an online anagram solver, but what fun is there in that? Anyway, my first instinct was to think that one of the words was a common article like "the" or "an". I'll just tell you, don't bother. Also, none of the words is extremely long, so don't get too fancy. Finally, my really useful hint is if you rearrange the letters you can spell "I envy teachers". (I guess I really meant to say useless hint. Fortunately I have another 51 weeks to come up better clues on future NPR puzzles.)

Edit: My post mentioned a "long-time yearning" and included the word 'year' a couple times. Time for the answer:

NPR Sunday Puzzle (Dec 30): And what does 2 + 0 + 0 + 8 equal?

NPR Sunday Puzzle (Dec 30): And what does 2 + 0 + 0 + 8 equal?:
Q: Take the equation 5 + 5 + 5 = 550. Make this equation true by adding a single line. Hint: The answer is not to put a slash through the equal sign to make it not equal.
I was excited to see a math puzzle this week, but then I realized it was an old math puzzle I'd seen many times before. You can probably find it if you look. An additional hint, you can't touch the equal sign at all, so don't get any ideas of changing it to ≤.
Edit: Time to reveal the answer since it is after the deadline:
A: Add a line to one of the plus signs to make it look like a 4:
5 4 5 + 5 = 550
