Warning: ***DO NOT LOGIN ON IOS*** GEM IS ON ANDROID If you plan to log in at IOS device, you should need to use ALL GEMS at ANDROID device. I won't take any responsibility if all gems disappear with the reason you logged in the wrong device. Please note: Please ensure that you can enter the game normally and then log in to the account, because the account password is one-time, the second login will be invalid, no warranty in this case.
