Solve Puzzles, win an XBOX 360* or PS3*

Do you like a challenge? Sign up here and we'll send you a 3-D foam puzzle, for free. (Limited to high school Juniors and Seniors, and college transfer students.)

Did you solve it? Tell us here and we'll send you the next one that's a little harder. Solve all three and we'll enter you into a random drawing for the new XBox 360 * (slated for end of 2010), or a new PS3* - your choice.

(* Xbox 360 and PS3 trade names are the properties of their respective owners. Random drawing held end of January 2011. Employees of the University of Illinois or their family members are not eligible. Limit one random drawing entry per person.)
