The use of color helps to limit stupid errors
I loved this game. I've played for a long while and only saw ads between games. Suddenly, I'm getting pop up ads in the MIDDLE of the game. And they're in CHINESE! What gives? I'll delete if it continues.
Been playing this game for years but the latest version now plays ads in the middle of gameplay. No more for me!
The game itself is still great but the ads have gotten out of control. An ad before you start and after it’s finished and in between. Some are really long as well. The really annoying part is having to click multiple times to close the ad even after it’s finished. Frustrating!
You can’t delete this app from your iPhone once you download it!
Had to delete due to offensive advertising.
Great game for you and everyone else to play
Web site continually crashes.
My pen doesn’t work with this app. So annoying when it pops up my keyboard.
