After logging out, funds are transferred to the return address and then to start a new game it is required to start the deposit process again.
About along time received into a return address? Sometimes the user must fast to return the games and only have available balance on that game, how much fee for that?
TOR browser had a slow connection, possible the user will log out every time and this makes extravagant fee also every deposit.
The game has been designed for tor network and sessions will not be lost if users are disconnected.
