The Handheld Digital Sudoku Game.

Popular in Japan since the 1980s and now a worldwide phenomenon, Sudoku, a combination of the Japanese words for single and number, requires players to complete their puzzle so that the numbers 1-9 appear only once in every row, column, and section on the 81-number grid. This handheld electronic game lets you play anywhere, presenting the puzzle on a clear, easy-to-read LCD touchscreen, with millions of different puzzle combinations. The game requires no math; players simply use logic to look for patterns, missing numbers, and repetition. There are three difficulty levels, as well as options for help if stuck and for creating your own puzzles. Two G13 batteries included. 1" H x 3 1/4" W x 4 1/2" L. (31/4 oz.)
