Denied a multiplayer game between members

for exmaple: Billiards 8 ball or poker..
when the game starts , each player has to bet " 20 nulledbb credit ...or more.."
and at the end of the game, the winner takes the credits.
(just like the idea of Miniclip's 8ball, but we use nulledbb credits instead)
i think that's gonna bring nbb members together , & make them more active )
