Great fun.
Lots of fun and works great.
Expert is good! Admittedly I've only played one level, but the game is stable. No glitches and is the appropriate difficulty for me.
Excellent game with good difficulty levels.
The best sudoku board design - the "chalk theme" is absolutely the best theme for sudoku I ever saw. But unfortunately, some games have no logical solution... so after one week I stopped playing it - you never know is it just very difficult game, or it is not possible to solve at all. I hope the author will fix that bug. Updated: after 3 years still the same mistake. Obviously the author gave up...
Good app and easy to read. I like the level of the more challenging games.
I enjoy playing Sudoku and this app was up there with the best but I've noticed that recently some grids are repeating again and again. The randomness is going, going, gone along with the enjoyment of what was once a great app. PLEASE check and correct if possible. I'd hate to change to an inferior app.
Excellent piece of work!
Top game one of my favourites.
Love this app! Great to keep your mind sharp
