I really like this app; nothing fancy, just sudoku that can be played off-line if you need to. Ads aren't bothersome. Challenging too - even the easy ones! I particularly like being able to have the pencil as a second line and having the ability to 'lock' it when filling more than one space. No fuss, no frills - just right! Thanks, developers, good job ☺️

Previous rating of 5, now 1 after update. The ads used to run once after a game, w/ 5 sec timer to X out. Now long ads run BEFORE & AFTER each game (2nd Update: Now ads also force open Play Store every time). I understand ads pay for the game, but doubling the frequency is too much and getting bounced out of the game automatically after every ad is ridiculous. EDIT AFTER RESPONSE: This makes me play far less, which means less ad revenue = bad business!

Update: We are still trying to do our best to keep the ads to a minimum, compared to the other similar apps. Thanks again for playing our Sudoku game, we truly appreciate every user, but adding ads is a matter of survival at this moment.

Hints *introduce* errors that can't be undone. The hint will frequently add hint numbers that the user DID NOT enter, only to explain why they are erroneous. But it only corrects one column or box worth of one number, leaving the user with a mess they did not create.
