Binary Sudoku Puzzle iphone puzzle app
Binary Sudoku: the concept has been around for a while. Each grid uses only 0's & 1's. Each row & column must have an equal # of 0's & 1's. No row can be exactly the same as another row. Ditto for columns.
The free version has 15 puzzles. The paid version has 100 puzzles. I did 1 easy, 1 medium & 1 hard levels. Definitely a nice change of pace from regular sudoku.
