Is there any type of law on hiring out vending machines/pool tables/coin operated machines etc....? - coin operated pool tables

I bought a pair of slots / table football, etc., and would like to know what laws and licenses, if they are truly needed and to know if you have suggestions on what works best and where I buy my shares for machine parts and more

Thanks
