To gamble legally in Michigan, you must be at least 18 for the lottery, pari-mutuel horse race betting, charitable gaming, and paid fantasy sports contests, and at least 21 for the three Detroit commercial casinos and any real-money online gambling, including mobile sports betting. The gambling age in Michigan for tribal casinos is set by each tribe individually, so it can be 18, 19, or 21 depending on where you go.
Where the Age Is 21
Michigan’s three state-licensed commercial casinos, all in Detroit, require patrons to be 21. The Michigan Gaming Control and Revenue Act makes it a crime for anyone under 21 to place a wager at these casinos and equally prohibits anyone from knowingly allowing an underage person to gamble.1Michigan Legislature. Michigan Compiled Laws 432.218 – Prohibited Conduct, Penalties Persons under 21 generally cannot be in designated gaming areas at all.
Every form of real-money online gambling in Michigan carries the same 21-and-over rule. That includes online casino games, internet poker, and mobile sports betting. The Lawful Internet Gaming Act defines an “authorized participant” as someone 21 or older with a valid internet wagering account,2Michigan Gaming Control Board. Michigan Compiled Laws 432.301 – Lawful Internet Gaming Act and the Lawful Sports Betting Act uses the same threshold for online sports wagers.3Michigan Legislature. Michigan Compiled Laws – Lawful Sports Betting Act, Act 149 of 2019 When you sign up, the licensed operator verifies your date of birth and confirms through geolocation that you’re physically inside Michigan every time you place a bet.
Where the Age Is 18
Several other forms of legal gambling in Michigan open up at 18. You can buy any Michigan Lottery product at 18, from scratch-offs to Powerball and Mega Millions entries. Retailers who knowingly sell lottery tickets to a minor face a misdemeanor charge.4Michigan Legislature. Michigan Compiled Laws 432.29 – Sale or Gift of Lottery Ticket to Minor, Penalty
Pari-mutuel wagering on live and simulcast horse races is also 18-and-over. Michigan’s Horse Racing Law prohibits race meeting license holders from knowingly allowing anyone under 18 to bet.5Michigan Legislature. Michigan Compiled Laws 431.317 – Horse Racing Law
Charitable gaming follows the same age floor. State rules bar anyone under 18 from playing bingo, handling bingo equipment, or buying raffle and charity game tickets.6Justia Law. Michigan Administrative Code R 432.21309 – Minimum Age
Paid fantasy sports contests, including daily fantasy platforms like DraftKings and FanDuel, allow entrants at 18. Michigan’s administrative rules prohibit anyone under 18 from creating a fantasy contest account or entering any contest.7Legal Information Institute. Michigan Administrative Code R 432.532b – Persons Restricted From Entering or Participating in Fantasy Contests Note that this is lower than the 21-and-over rule for online sports betting; fantasy contests and single-game sports wagers sit under different laws.
Tribal Casinos Set Their Own Age
Michigan has tribal-state gaming compacts with 12 tribes, and each tribe decides its own minimum gambling age. Most tribal casinos in Michigan admit gamblers at 18. A handful require patrons to be 21, and at least one sets the line at 19. The age can also differ between the gaming floor and other parts of the property, like restaurants or entertainment venues.
Because these rules are set tribe by tribe and can change, the only reliable way to confirm the age is to check with the specific casino before you go. Kewadin Casinos, for instance, lowered its minimum from 21 to 18 in 2022.
Penalties for Underage Gambling
Gambling underage at a 21-and-over venue in Michigan is a misdemeanor. The offense applies both to the minor placing the bet and to anyone who knowingly allows it. A conviction can bring up to one year in county jail, a fine of up to $10,000, or both.1Michigan Legislature. Michigan Compiled Laws 432.218 – Prohibited Conduct, Penalties
Those are the penalties for straightforward underage wagering. The same statute carries much steeper consequences for related offenses like using fraud or a fake ID, which can escalate to felony charges with up to 10 years in prison and a $100,000 fine.
Winning doesn’t help. Michigan law subjects gambling-related property to seizure and forfeiture, and money obtained through illegal wagering falls into that category.8Michigan Legislature. Michigan Compiled Laws 432.219 – Property Subject to Seizure, Confiscation, Destruction, or Forfeiture An underage gambler who hits a jackpot has no legal claim to the payout and may pick up a criminal charge on the way out.
