Good gameplay, but the ads seem excessive and unnecessarily complicated. Ads will play automatically after each game ends, occasionally when starting a new game, and also when resuming after pausing. Most of the ads are "skippable" but "skipping" takes you to the play store. Then you have to return to the game and then finish the next part of the ad before being able to close it. It really says something about the game when most of the reviews talk about the ads....

fine puzzles, but ruined by the vast amount of ads. Completed a puzzle? Ad. Paused a puzzle? Watch an AD to unpause. Failed a puzzle and need to restart? Ad. I've gotten a few redirects to "you have a virus" scam webpages while playing this game as well. Not falling for "we're a startup" either. how many games does this publisher have with built in "remove ad" purchases? 42?

Hi, sorry for such inconvenience. As a startup, we have to survive and support further development by integrating with ads. Some ads can be skipped after watching for 5 seconds. You can also purchase the "Remove Ads" service to enjoy a no-ads game. If anything else, please reach us at sudoku@fungame.studio. Thanks a lot. :-) - Lily

I got rid of the last Sudoku game I had because the ads were getting ridiculously long and would force you to go to the Google store. saw this one and wanted to give it a shot because it said it was an "offline game". Not only are the ads just as long and you have to click the close or fast forward button 3 times, you get and ad before AND after the game! No thanks, removing.

Hi, sorry for such inconvenience. As a startup, we rely on ads. Some ads could be skipped after watching for 5 seconds. Our game's core gameplay can be enjoyed without an internet connection, but certain features like watching ads for doubled rewards require an active network. Reach us at sudoku@fungame.studio. Thanks!
