Works great w/ Surface Pen

This Sudoku app works great w/ my Surface Pen. It feels like I'm doing the puzzle on paper-it's awesome!!!

Outstanding technical support!

I had a problem where the puzzle never appeared after making my selection (easy, normal, hard, evil). I emailed tech support and they assured me my stats would not be lost with a reinstall. Everything has been worked out and I'm back to enjoying the app!

Need to add the ability to erase individual cells.

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
