I bought my roulette wheel off a guy who ran a casino in NH, Tom knows the story. Anyway, he said that by state law, X% of all operating profits had to be pre-designated to go to a registered state charity. So basically, every day he was open he would advertise a charity, and the percentage of operating profit would go to them. Not sure how often the remittance had to be done, whether it could be done quarterly, or whatever. And I don't know if there were restrictions on the charity. It could be a school sports club one day, a hospital another day, etc.
He told me he was selling the wheel so he could upgrade to a dual-table with digital projection. It sounded like business was good.
