Guys. Cheating is not a option. So don’t talk about that please 
Cheater have little thingy 
The only time I quitted by closing the app was when my opponent had me in the sleep lock with 2 legendary sleepers. I knew I had lost, but I still had alot of monsters left. I didn’t want to waste 5 min just to watch him win when I couldn’t do anything. So to fix this problem please let people use the “Run/forfeit” buttom at anytime. From what I remember you can’t get out of a fight when it is your opponent’s turn and it is never your turn if you are in a sleep lock…
By the way I didn’t know people got worse reward when people closed the app like that.
Im sorry RNA Lucrayzor.
Thankfully once i know i lose, i instantly resign/run instead of using the “easy” way out
