There's an ad everytime you think about a move for more than a few minutes and fill a square, this can easily make you lose track of thought. Worse still, they often cannot be easily skipped and take multiple clicks and a visit to the app store. Also lacking dark mode, other than that it is good, but the insufferable amount of ads have made it a no-brainer to remove.

Hi! Thank you for your feedback. We’re sorry to hear that ads during play feel disruptive and affect your enjoyment. We understand how frustrating that can be. We appreciate you letting us know, and we’ll continue working on better balancing ads and gameplay. For a softer look, you can use device features like Night Light to reduce brightness.

way too many ads in the middle of a game. I also usually don't like that mistakes are made visible instantly. it has a lot of side events/games (which I don't know what they are good for). in general it does what it should I guess. I feel like the "extreme" level is mostly not hard enough though. I would not recommend it because of the ads though.

Hi Julia! Thank you for your valuable feedback. We appreciate your insights on the ad experience and its impact on your enjoyment of the game. We are committed to balancing app support and user experience. You can disable the Auto-check for Mistakes: tap "Me," go to "Settings," and turn off the "Auto-check for Mistakes" option.

The game makes you watch ads for rewards, and then doesn't give the rewards. sometimes two or three ads, and no rewards. Then the game crashes, and you lose all your progress against whatever puzzle you were working on. Then they want to run tournament events which depend on completing puzzles with all this going on.... Simply terrible
