Michigan does not condone home poker games. Social gambling, for the most part, is illegal in Michigan. There is an exception, however, for senior citizens within a senior citizen housing facility, where there are at least 15 members age 60+. There may not be more “guest” participants than resident/club member senior citizens, and it must be a “recreational” poker game, meaning no more than $0.25 per bet, and no single-hand pot exceeding $5.
