If players try to quit a game, they have 5 minutes to rejoin or else they will lose the bet (This might actually take them into the negative if they spend more coins in between!!!!!) Frankly, it is a fitting punishment for cheating the dealer.

If the server turns off while their game is on this waiting period, they suffer no penalty.
