I love playing this game but sadly I haven't been able to do so. Anytime I click on the play game bubble an ad will pop up I will click on the ad like it says to do yet it will not go into the game it doesn't do anything but want me to click to play a game and then it goes back to the same ad as before I really like this game but if this problem isn't fixed soon I'm gonna have to delete it because what's the point of keeping a game I can't even play

Too many broken ads (1.0.3)

This game is really fun! I've been playing off and on for a few years and was only up to about 500,000 points, but then I just opened the app and they were all gone. Back to level 1. I feel so lost! Why, Cookie Masterson, why?!!!

A classic (1.0.3)

I used to have the best time with this game until something major happened, and I lost everything. I used to be on at least level 25, and now I'm back at the beginning. I don't play with random people anymore when I was in guest mode. My picture just moves up and down the left side of the screen depending on if I got the question right or not, while the other random people stays at the score of 0. Making me win at every game. I have tried deleting the game and downloading it a few times, and I'm still having the same issues.

No point in playing this game because one day all your progress will get wiped with no explanation. Terrible!!!

Spent 5 minutes just trying to get to play a game for free, at least I thought you were supposed to be able to. Obviously the programmers need to go back to school or get there money back
