Crosspix

Crosspix puzzles are deceptively simple, very much like sudoku. Through a logical process of elimination and comparison, you use the numbers provided to determine which squares should be filled in. The biggest difference with sudoku being that, when you finish, instead of a grid of numbers, you have a pixillated picture to tell you if you've completed it correctly (as well as an answer key, of course). In the end, if you've completed the puzzle correctly, a picture reveals itself. Animals, sports, holidays, symbols -- a surprise is guaranteed behind every grid! Crosspix includes complete instructions as well as an answer guide.
