How about a poker co-op?
Basically every week all players in the co-op would put in an a set amount of money every week lets say $5 then two players would get 50% of the weeks buy-ins to play with. Every week two more players would get the buyins.
These players would take the weeks buyin if any left and the profits and these would be put back into the total pool. After a set amount of time We all split the profits
