Very enjoyable! I do a puzzle every day for my lunch break. Everything you could want from an inexpensive app, and it is actually FREE! Perfect! I wish it had some mellow or relaxing music as background sound though...maybe that could be added as a future update!? Thanks

Good game, easy to use, hardest levels are actually a bit challenging.

A good way to kick off brain activity for the day. Didn't like the few times the game froze and kicked me out, but the time kept running, in a couple of instances for a whole week or more.

I like the interface, but the puzzles are too easy.

Ancient Look

For the most part, it is acceptable. The numbers presented contrast too much with the numbers that the player places. The purpose of the game is to enjoy a challenge in thinking; not a visual one on top of it.

Good for moderate level players

I enjoy that this app is easy to use and easy to access. I wish there were more difficult levels.

Sudoku Review is Excellent

The extra features that come with this game makes it easy to play. My favorite is the auto-update of the suggested numbers when a number is chosen.
