Unfortunate end

I used to play this game religiously back when it had few ads, as life got busy I dropped it for a few years. Came back to update it and play again but now it won’t even launch. I checked reviews to see if anyone had similar issues but the most recent complaints are about the excessive ads. If the ad problem is that big then I see no reason to attempt to fix my launching problem. I did try to uninstall and reinstall but that didn’t work. It’s an unfortunate end to an app I enjoyed very much.

Overrun by ads

I’ve used this app for years and recently its user experience has become completely abysmal because of ads! You’re forced to sit through ad after ad with no option to exit and return to the sudoku. Quitting the app multiple times just to clear the ads means I often give up on the sudoku altogether due to the hassle.

Good but

One of the better sudoku apps but wish it had the option to turn off the vibration when you put a wrong number in a cell. Ruins the game knowing you’re playing with guardrails.

The Ads

Good game however the ads are intrusive. Every action has another ad. No paid version available.

Огромное количество рекламы

Рекламы через чур много! И идут одна за другой и не переключаются
