Fine but needs things. Puzzles are easy even on fifth difficulty and they are all 3x3 size. Also needs some kind of progress saving through google+ (maybe even achievements). Unfortunately I rarely see AI Factory Limited actually changing something in their games so this is probably finial product. I don't recommend this game, there are more engaging sudoku apps out there.
Limited perfection As with all AIFactory games really beautiful interface, but I would prefer another colors, personaly I do not like green, it's not necessary to use strictly different colors for different games. Missing automatic random selection of the next problem with the previously selected level. Only 5 simple difficulty levels, NO REAL BRAIN-TEASERS, e.g. with only 17 numbers set only.
backup & restore? I really need a way to backup my game, getting too far without it is going to be a huge waste of time.
Now deleted. I downloaded several versions of this game (all the others were free!) and I found this one to be the least helpful. I could not find a number of the items mentioned in the 'How to Play' instructions..I have now deleted it.
I've played like 200 games and take like the interface. Ads are not distracting.
Simply the best Sudoku app on android for having a pick up and play UI, effectively using screen space, and looks good.
1.43: Timers now stop when app is in the background. Reverse portrait orientation now allowed (on some devices).
