Numbers are too small. I often fat finger the wrong number and get an error. I then have to watch an ad after I do it three times. I also have to watch an ad to auto fill. Filling in initially is tedious. I like that it removes the number in the same column, row, and group when you select the final number I don't like the highlighted column, row, and square, but I could get used to that. I would give it five stars if it had only one ad per game. Love the detailed hints.

EDIT: Seems better lately. ORIGINAL: Too many ads and ads that take control and don't release so I can go on with game. I've given it 3 chances to work better. No improvement. I watch a lot of ads, but when I'm not interested, I don't want to be forced to watch. That is just unpleasant. Great tool for teaching how to observe details but too many interruptions.

The ad for this (3x's/day or more!) claims it is an update for Andoku 3. I installed it, but liked Andoku 3 better so I uninstalled it. Andoku 3 is still on my device, so there is no relation and the ad is a lie. Andoku 3 has an addon that takes pictures of newspaper, etc. and converts them into Sudoku puzzles that you can solve within Andoku 3.
