The game was fun until the dev cut the 1 life you could get every 15mins to every 3hrs. Then they cut your ads for free gems from 800 to 300 daily. I've placed in to win gems and coins in dozens of tournaments. Single and team events. I've gotten rewards twice! Mostly you get nada! I've contacted support on this and no response. The devils just want you to spend instead of being able to free roll the game. All good. I'm uninstalling the game.
