Sudoku has become a phenomenon. Dozens of variations have been produced. Michiel Allessie has produce an appealing new version called Binary Sudoku. Only 0's & 1's are used. Each row & column must have an equal number of 0's & 1's. A number can never be used consecutively more than twice. So, if a row contains 0, blank, 0, then the blank must be 1.
The puzzles come in 3 grid sizes: 8x8, 10x10 & 12x12. On the ipod, the 8x8 is a manageable size. 10x10 & 12 x 12 would be better for the ipad.

Don't buy this. Puzzles often have multiple solutions, and it is not really a sudoku - at best it is a latin square game.
ReplyDeleteAdding diagonal constraints and prohibiting 4 in a row instead of 3 makes this puzzle more interesting.
