A twist on the popular math puzzle Sudoku, here letters in every grid form a picture and instead of squares, become cool-looking shapes including a rocket ship, a teddy bear or a windsurfer. To make things even more interesting, the company has added a few more twists. Three of the puzzles don't have word lists. Kids have to create them from the clues given and, to top it all off, each puzzle has a hidden message. Once kids have circled all the correct phrases, the uncircled letters will spell out a silly quote, fun fact or a punch line to a riddle.
