After becoming a phenomenon in Japanese newspapers and then winning countless fans in the U.K., the simple, numbers-based puzzle game Sudoku comes to North America in the form of this Game Boy Advance title. Sudoku is played on a 9 by 9 grid of 81 squares, some of which contain numerals (but most of which are empty). The object of the game is to fill in all the blank squares such that each row and each column contains each numeral, 1 through 9. Dr. Sudoku includes 1,000 hand-designed puzzles. A special feature allows players to "pencil in" numbers, to better visualize possible solutions, making the game more relaxed and comfortable, as with a newspaper Sudoku puzzle. ~ T.J.
