Used to be playable but recently about every 7 out of 10 casts in duels cause my game to crash. I have lost power ups, position in rankings, challenges, and money. Before this I would give 5. Had good rewards, the only time u paid for anything was when you wanted to speed up leveling, but everything is free as long as you are patient and prioritize for tournaments. Fun game but if the crashing issue is not fixed soo it will have to go.
