I really enjoy this game and over the past year my skill at all levels of the daily puzzle have grown, so I decided to go back to the killer sudoku. This is where my primary suggestion lies: because this is a more difficult challenge, please make your “easy” version a 6X6 rather than a 9X9 sized puzzle so that newbies can build up without getting too discouraged. Then it will be perfect :D

Great Game But....

I love the game except for the ads. I don’t mind having them but they delay starting the game and the timer starts immediately. Consequently I have to restart the game or start after 15 or more seconds have elapsed. There’s an X to clear the ad but it's easy to miss it which will open the browser which is a pain in the a... .

It’s a pretty good game though not as intuitive to play as others


I had another Sudoku game that was more fun but it is now gone after the 11.0.1 iOS update. This one doesn’t always respond as expected so it slows progress a bit. However it is fun. Being able to auto clear ‘marks’ is really nice.
