You are the banker, my system is a "play money" site that you control and can run games in whatever currency you want

Only you can increase, decrease, and check the balances of the players that sign up under you.



So say you have 7 friends,  you are the host,  You give them say 1000 chips for 1000 bits ect.  then after games are done, you check balance and cash them out yourself,
