Unironically ban all gambling
My brain which doesn’t find gambling fun stays winning.
Also yes ban all gambling, if people want to gamble let them gamble with some friends in their homes.
Once for a company party they had two casino workers come and set up a blackjack and a roulette table. Everyone then got a stack of chips and we played the games for an hour or two. It was great fun but a huge part of the fun was how we were not playing with real money and could just laugh about how nobody had any chips left after two hours.
