"Parents will be fighting their kids to get the Game Boy," says Bill Swartz, Head Woof at Mastiff. "Sudoku fever is sweeping the country and the fiendishly addictive puzzle game play is perfect for Game Boy Advance. On Game Boy Advance we offer everything there is in the paper version, more volume than in any book, and a help system. The best of two worlds."
Sudoku is the international puzzle craze that shows no signs of slowing down. The New York Times remarks, "no puzzle has had such a fast introduction in newspapers since the crossword craze of 1924-25," and USA Today says Sudoku has "become the morning brain breakfast for millions of commuters." The Economist magazine calls it a "puzzling global phenomenon."
Sudoku looks like a math problem, but it's not. The rules are simple: start with a grid consisting of nine three-by-three squares in which some of the numbers are already supplied. Fill in the blank squares so that each column, row, and three-by-three grid contains a number from 1 to 9 with none repeated.
