Good idea, and diversifies the casino, plus enriches the community.
Rather than talk about your black jack hand, you are bluffing one and another... could start some funny beef between rivals at big stakes poker tournaments.
+1 adds to the casino, i would definitely have the tables go up in levels of buy ins like for the people who dont have alot of money to the high stakes tables where you would be given set amount of chips like 1k worth but you bought in for 50k for example and whoever was the last one in then they would get everyones buy ins
