I enjoy almost everything about this app, except for the feature added in the latest update: "Implemented a brief notification upon puzzle verification." This notification covers the puzzle for a few seconds and makes it difficult to get a quick check. I need the ability to turn it off and go back to the simple flashed checkmark of before. Removed 1 star because of this. Sudoku without the annoying gimmicks. Simple, easy-to-use interface. And unobtrusive ads that are almost always muted for me.

Best Sudoku app I've tried. Numbers laid out in dialpad format which makes them easier to tap than other apps. Pencil marks correspond to where the numbers are on the numpad, cohesive. Many difficulties with good tutorials on techniques specific to each level. Animated details, like the true number in a cell growing from the candidate when you enter it, add to the polish. Configurable assistance and input settings. Minor nitpick: the numpad could utilize more screen space on newer tall phones.

E2: Ads better. E1: The ads have brought it to the point where I hate turning it on now. It's a shame. Otherwise one of the best sudoku apps out there. Old: I love this app so much! I love Sudoku in general, but this app makes it so much easier to play. I'm also a self taught player who used to play on the newspaper, so the little tutorials on different levels are pretty cool too. Tricks I've never thought of. This app makes marking and erasing way easier, which is the main selling point for me.
