I think it would help to add a multiple number feature. Being able to more than one number in a square. That is how I solve my puzzles that are on paper.

Good game. Too many repeat games. Needs more variety.

This app works nice, but needs higher complexity puzzle options. Difficult level can be easily mastered.

Sudoku -- great game

Sudoku Free is a very fun program. The puzzles go from easy to pretty difficult, but are always fun to solve. I solve about 90+% with no help. Thanks Microsoft for this fun puzzle game

This is a good way to play Sudoku until you are nearly finished and it quits working and you must leave before you are done and can't get it back and have to start all over!
