A new rule for Missouri’s casinos–one most of them have already been adhering to for a few years. The Missouri Gaming Commission has turned into a rule a policy that sees casinos pay players most of the take from so-called progressive wagering, or “side bets” on card games. The new rule calls for at least 70% of the take from these side bets to be distributed to the players, with the House allowed to keep up to 30%.
