One of the best sudoku apps available. Literally thousands of puzzles, and the ads/monetization is very sparse. Offers a good range of difficulty, from easy/medium to some extremely difficult ones. Literally could not ask for a better free app. My only minor nitpicks are the controls could be a little more intuitive, and maybe some diverse UI options would be nice. Also if placing a number could auto clear candidates in the same block/row/column that would be cool.

Game is annoying... you can't click on a square without changing it, unless you change the number first, which sometimes you don't want to do. Regardless, level of difficulty is not more than "easy". Games are cleared with no thought necessary... Minimum ads is good.

It'd be an improvement to have a note automatically deleted once we fill the corresponding digit in a square. I.e. if I have 1 in notes across the board and I set a regular 1 in a square, all 1 notes should automatically disappear. Also, checking for mistakes should be feasible at any time during the game, not only once all squares have been filled out. And last, we should have a button to show the mistakes so that we can correct them during the game.
