This a great app with some nice features but has a few issues in my opinion. The variance in complexity of Expert puzzles is very high. Some can be finished in a few minutes, others can require multiple extremely difficult deductions in succession to advance. Most require complex chaining which I don't enjoy and some even force you to use trial and error. The solved digits not being distinguishable from the given digits is also a problem. Tone down expert or add a difficulty in between please.

One of the best classic Sudoku apps! Very few adds, and they're short and only between rounds. I love the 5 difficultly levels, so you can really tailor the challenge to exactly where it's hard enough but not too frustrating. Love the auto-note option to save time (so u can narrow down the right digit faster). Much better than a few other sudoku apps I've tried. I LIKE that there's no story or goal to earn points to buy/unlock/customize, but that might be lacking to others. Just classic puzzle

DO NOT DOWNLOAD THIS!!! This game used to be fun. But now the ads have gotten longer and longer and become impossible to close out of, even when the X to close them is in the corner. I understand the game is ad supported, but it crossed into deceptive abuse when it is impossible to close out of the forced ads. They make the ad close buttons so tiny that it opens the Play Store, again and again and again and I never get to actually play sudoku anymore. Don't bother with this one.
