Sudoku - Classic

Wish it kept your best scores. Also the "unsolvable" are solvable, i think it could be a translation issue. How about "Master", something higher than expert but not unsolvable. Thank you for the game, it's currently the only game left installed on my phone.

As you get better, the game gets more difficult. That's good because you don't get bored. The background has stopped working. Ads pop up often after you have finished a game. Close the ad and your choice of the level for the next game shows up.

It doesn't open and of its note than one phone it's not the phone.
