I moved to this Sudoku app because the previous one kept opening phishing web sites on my phone. This app does not do that. What I don't like is that this app's display is not as easy to read. I also do the daily puzzle every day, but have never been able to keep a streak going because it calculates streaks by 24 hours, not by a calendar day.

Great but soooo many ads. It's hard to really get into the game and relax when both before and after most levels you've got an ad. You also get ads if you pull the app down and then back up again. I get there being some. but it's getting excessive and ruining the experience. Otherwise, this is a pretty good sudoku app. I like it, except for the excessive ads. I don't want to sit here and play level after level after level when my reward for completing a level is another ad, every time.

Hi, thank you very much for the support! As a startup, we have to survive by integrating with ads. Some ads could be skipped after watching for 5 seconds. You can also feel free to purchase the “Remove Ads” service to enjoy an ads-free game. If anything else, please reach us at [email protected]. Thank you! :-) - Jowanna

Huge battery drain - 8% in 2.5hrs on Galaxy Z-Fold 5. Ads are frequent and intrusive to the point that it's quicker to kill the game and restart than to watch them. All that said, the gameplay is very good.
