16! The only 16X Sudoku oun the market that I know of. I only ever did the 16s, 9s were to easy. I used to buy 100 page books of 9s just do to the 3 16s in the back and recycled the other pages. Now I have its great app with so many 16s I'll not have to buy another 9s sudoku book again. Thank you soo much.
Great apps I have tried both 9x9 and 16x16 puzzles, it comes with great color themes and soothing music. The check button is useful (and cheat) feature that shows the player invalid values, thus speedup in solving the puzzle. Very well written apps.
Ok, needs to be better and allow you to pencil in options. Adding color would be nice, and if selecting an already existing number, highlight all if that number to make it easier to see
Galaxy Tablet I wish you could see the pencil marks in the boxes rather than the bottom corner. If you could make that happen, you would definitely have a 10 star rating from me!
More than basic game. It would be nice, if it made it known when you have finished with individual #'s. Like when all (9) of any # were all in play on the grid.
Entry layout odd but workable. Will play but will uninstalo unless enhanced layouts added
