Free version has 120 puzzles - 40 for each level. There are also daily bonus puzzles. The irregular level is awesome & really works your brain. Unlike some, this app lets you check your progress for errors and doesn’t penalize for undo’s or restarts, etc. You can clear games and replay to better your time. Haven’t been bugged to purchase anything. Just good old fun!

I like this sudoku app best. The error notification is quite helpful if you want make sure you made a correct entry.

I am enjoying the variety of puzzles. Unique ways to play! Addon puzzles seem to be a little expensive. Unsure how their pricing compares. Hoping they will offer packs or sales.

My only complaint is technical but could be easily corrected. Color blind people can't see errors in red. Change it.
