Freezes Often - frustrating

Play about ten games and it freezes and the only way to continue play is to hard reboot. I use iPad and iPhone and dont know if this problem is caused by the OS or not but it should be fixed because there are a few Apple devices out there.

I wouldnt mind so much if the game was lousy but its a lot of fun. Please fix the problem.
