The Perfect Fix for the Sudoku Addict!

EIC Lady

Review 2.0: I've been playing this version of Sudoku for several months now, and I want to thank the app developers for providing a version of the game for the adults! No funny animals, no storybook themes, no frantic distractions! Just a great app with plenty of boards to challenge you. For the greatest variety of challenge levels and no ads to distract you, spring for the "pay-to-play" version. It does not disappoint. Every player, from the beginner to a master's level player, will find a grid to their liking. Enjoy enjoy!

Review 3.0: As I said before! Simply, the best.

Diabolical needs to be more difficult


It's a good line sudoku game. Evil is easy though, and I rarely get to use a trick (or whatever they're called). And diabolical usually involves a chain. Still, it's a lot of fun and my favorite sudoku game so far.

I do have a request. Once a mode is selected, it should stay that way until it is manually changed. It drives me nuts that I can be in notes mode, then I click on a number and it changes back without my changing it. Please correct this, thank you.

Back to five stars - thanks for Retro option


Update: Excellent response from app management to users requests. Happy again!

Update: This is really upsetting, I hate the new color themes, should give the option of choosing the old color theme. I play this game more than twice a week, but I'm already looking for an alternative .......

Old write up: Excellent interface. The way I mark it on paper. After two years, I'm still enjoying it at least once a week.
