As with every other type of gambling, this is going to depend on the state in which the community resides. So, what you are going to need to do is contact your State’s gaming board and discuss with them the legality of Bingo in retirement communities. Although, after a bit of research it seems that it is allowed if conducted by a Non-Profit with very low winnings. So again, contact your State’s gaming board to get all of the information you are looking for.
