14/07/25 after years, I just deleted it. Ruined by update, impossible to use. 18/08/2020 Pro: tons of puzzles, of different levels. Highlighting by number, Pencil marks Con: When highlighting a number, it only shows boxes with a decision :(it does *not* highlight pencil marks of that number. This makes it much more difficult to see patterns and work out logic. I would suggest adding a Settings option: "Include pencil marks in highlighting? Yes/No" That would raise the app to a 5 IMO. Thanks

I like new update, themes are now easily accessible on main menu. New Game mode is good and very satisfying + old classic packs style design is there. Looks like perfect sudoku app now specially after this latest update.

The puzzles are too hard. They're like a level or two above what they say they are. Like, easy isn't easy. It feels medium or hard.

The ads that play at the end of a stage now force you to go the advertised game's Google Play Store page in order to close them. There isn't a way of skipping that. Please change this back to how it was before.

This was a great version of Sudoku... straightforward and no frills.... And then, last week, it was updated! (Dumbed-down) Pointless animation and poor contrast between numbers on the playing board. I'll be deleting this app and looking for an alternative.

Sudko is a marking game, but I have seen no mark for next move this is not hard that missing mark from the game...
