This game is an ad generator. Every level has an ad, you spend more time watching the ad than answering the quiz. It's very unreasonable and sometimes two ads pop up next to each other after a level and you can't skip it unless it plays for 30 seconds. No incentives for the player for watching it. Really unfair and annoying. I would've rated this 0 stars if I could. You can't enjoy the game because of how much ads there is.
