I don't know what happened in the last few days! 10 (TEN) ads before your first round each time you open. then an additional five after first round, two of them video you must watch! that's it! sorry, but that's completely unreasonable. the app is done, deleted, and will be forgotten. I know ads are necessary, but not 15 per round. that's insane.

sorry for the one star! I just couldn't vote for 5 (due to my Mother's phone issues + you can search up) I like the game but there's two issues I really don't like anymore!! 🙏🙏 1. there's too many ads 🌿(even though I bought no ads) still pops up!! I just like to know if there're any issues on it or is it just my mother's phone 2. there's too many teams and I couldn't find one because everyone is using "multiple teaming🧍" not to be rude but it's kind of getting a little frustrated 😵‍💫

After playing a round and watching through an ad, you will have to exit out of pop ups for over a minute before you can play again. Very clunky user interface and an overabundance of unnecessary interruptions just to play the game. There are many reviews complaining about the pop up quantity, as well as the timing of ads ruining the flow of the game, and the devs only ever respond saying they need ads for years, without adjusting the ads to a better level to make a better user experience AVOID
