To start you off, here's a challenging "Cross Number Puzzle." The grid above is filled in like a traditional cross<i>word</i> puzzle, except every answer is a three-digit number (100-999) rather than a word. <i><b>Warning: </b>some of the clues may have you going in circles but there <i>is</i> a unique solution.</i>.<br />
<br />
Don't worry, you can get around to your other resolutions, like not procrastinating, and going to the gym later. Go sit on the sofa and work on a puzzle instead!<br />
