Improved successor to Roman Masek's OpenSudoku Dark theme is great. However I would love either customizable color or at least a full black and grey theme. Also a bug that still exist since Masek's version causes Undo to Checkpoint not to work. When save checkpoint is used from a resumed game without changing any data, it won't save and you can't undo to checkpoint.
This is by far the best Sudoku I've found on Android. Pros: Ad-free, lots of options for input style, nice UI. This would be a 5-star review if it included all 500-ish puzzles instead of requiring a manual download. This would also eliminate the need for the network access permission altogether. One feature request: instead of only storing the *latest* time for a puzzle, it should store the *fastest* time as a "high score" to beat.
No ads I like it!
Added turkish language.
The BEST sudoku you will ever need - All in there!! Absolutly stunning gameplay!
