Hands down the best sudoku app I have found. The tutorial section outlines what techniques are added to each level of increased difficulty, allowing you to learn as you progress. Clean, easy to use interface with plenty of assistance options (or none, if that's your thing). I can't speak for the ads as I purchased the ad removal. 12/10 I reccomend.

Very good app, I would really like it and would upgrade it if indicated the row and column as you touch the grid. I have found one puzzle (Hard standard #224) that has a mistake. It is possible in that puzzle to do only legal moves and still send up in a stalemate of one empty cell and no way to complete the puzzle. I am reducing my rating because of that.

Please use the "show hint" feature from the menu, it will point out any mistakes you might have made. The one and only solution for Hard standard #224 is 813759642 459623781 672148539 591487263 764532198 328961457 936214875 185376924 247895316.

Ive been using this for several years. On the one hand I wish there was a way to show different levels of candidates, perhaps through coloring. On the other hand, that feature would really be nothing more than enabling guessing and backtracking, therefore I'm forcing myself to learn the strategies the experts use. So, 5 stars.
