I play this on a Samsung Note 8, so I don't know how many of you will experience the same issues I have. The game crashes very often and if you're somehow unlucky enough to get the unexpected error message you'll either have to lose all data and start over when you reinstall the game or just delete and transfer data if you were able to save your account details before getting the error message. Game mechanics are simple and fun. Guaranteed 4 or 5 star characters when doing x10 draws. Amazing graphics and interesting original story. A bit difficult to level up town and characters as some conditions are difficult to fulfill.
