Why Detroit’s Floors Are 21+ and Kewadin’s Are 18+

The three Detroit commercial casinos, including MGM Grand, operate under state law that sets the gambling age at 21 and over. Tribal casinos run under tribal-state compacts and set their own age. That’s why the Sault Tribe’s Kewadin casinos have admitted players 18 and older since March 30, 2022.

The split carries over to cards. Poker at MGM is 21+, while some tribal poker rooms, such as Soaring Eagle’s, seat players 18 and older. MGM’s sportsbook counter is also 21+, and a sportsbook inside a tribal casino may follow that tribe’s own age instead. If part of your group is too young for the Detroit floors, use our breakdown of which Michigan venues take 18+ players to plan, and the guide to casinos across Michigan covers properties outside the city, with tribal casinos listed in our tribal casinos guide.

What’s on the MGM Grand Detroit Floor

The casino has more than 140,000 square feet of gaming space and is open 24 hours, so there’s no closing time to plan around.

Slots and Video Poker

The floor has thousands of slots and video poker machines. We couldn’t find a published payback figure, so be wary of any number you see quoted for this floor’s machines.

Blackjack and the Table Pit

Blackjack is dealt in the table pit, and it’s the game on this floor where your own decisions change the odds you’re playing against. Those decisions work the same on a Detroit felt and on a screen, which is why our blackjack strategy guide is worth a ten-minute read before the drive.

The Sportsbook Where Michigan’s Legal Betting Began

Michigan’s legal sports betting opened on March 11, 2020, and some of the state’s first legal bets were placed right here. Today, the BetMGM Sports Lounge takes bets at the counter and at kiosks, with 60 HDTVs and 14 video poker machines built into the bar top, so you can play a hand during the commercial breaks without leaving your stool.

Rewards Card and Promotions

MGM Rewards is the casino’s loyalty program. Your card tracks play at the machines and tables, so pick one up at the rewards desk before your first bet rather than after, and ask there which promotions are running on your dates.

MGM Grand Detroit Poker Room: Games, Stakes and Tournaments

Greektown and MotorCity both closed their poker rooms in 2024, leaving MGM Grand as the one Detroit commercial floor still dealing live poker. The room closed in the March 2020 shutdown and reopened in January 2021. Today it runs about 20 tables and is listed as open around the clock.

Cash Games and Stakes

No-Limit Hold’em is the main game, usually at $1/$2 and $2/$5. Pot-Limit Omaha runs too, and bigger or mixed games start up when the room is busy. Games and table counts move with demand, so call ahead or ask at the poker desk before you drive in for a specific stake.

Tournaments

The room runs regular weekly tournaments with re-entries, and you’ll need an MGM Rewards card to sit down. Buy-ins and start times change through the year, so pick up the current schedule at the poker desk before you plan a trip around one.

Where You Can Still Smoke

Since December 2022, indoor smoking has been limited to two enclosed rooms called Smoking Slots East and Smoking Slots West, plus an outdoor patio. The rest of the floor is non-smoking. The room names point to slot areas, so if you play tables and smoke, expect to step away from your game for a cigarette. Policies like this get revisited, so check the current smoking areas when you arrive.

What Amenities Does MGM Grand Detroit Offer Beyond Gambling?

The Hotel

The hotel has 400 rooms, 65 of them suites, and a standard room runs 510 square feet. If you plan to play late, booking one means you’re upstairs in minutes instead of facing the drive home, and the hotel has long held Forbes Four-Star and AAA Four Diamond ratings. A $20 million refresh of its rooms, suites, spa, gym, and pool finished in 2025.

Restaurants and Bars

For dinner, D.PRIME is the steakhouse, and Detroit Central Market, the food hall in the old buffet space, covers noodles, Detroit-style pizza, wings and coneys. TAP is the sports pub, The Roasted Bean handles coffee, and AXIS Lounge and 32 Degrees pour the drinks, with live music and DJs at AXIS.

Spa, Pool and Entertainment

IMMERSE Spa has treatments, an indoor pool and a fitness center, all part of the 2025 refresh. For something social, the Topgolf Swing Suite lets your group take simulated golf shots between sessions, and concerts and comedy nights play at the resort’s event center, so check what’s on for your dates.

Events and Private Parties

The resort has about 30,000 square feet of event space and can seat gatherings of up to 1,200 guests, from conferences to big private parties. Check the resort’s events calendar before you settle on a date, since a big booking can change how busy the building and the garage are that night.

MGM Grand Detroit Casino Hours, Address and Contact Information

You’ll find MGM Grand Detroit at 1777 Third Street, Detroit, MI 48226, on the west side of downtown by the Lodge Freeway. The floor is open 24 hours a day, every day of the year, and you have to be 21 or older to gamble.

The resort’s toll-free number is 877-888-2121. Hotel check-in is at 4 p.m., and check-out is at 11 a.m.

Parking

The casino has its own eight-story self-parking garage at the Lodge Freeway and Bagley Street, so drivers coming in on the Lodge can get off and into the structure without hunting for street parking. Valet is available too. Self-parking is listed as free, but check before a concert or game night, when downtown fills up and the garage can too.

MGM Grand Detroit vs. MotorCity vs. Hollywood Casino at Greektown

If live poker is on your list, the choice is already made: MGM Grand is the only one of the three still running a poker room. It’s also the busiest of the three by revenue, taking $605.3 million in 2025, 48% of the city’s total, according to the Michigan Gaming Control Board. The Michigan Gaming Control Board renewed all three Detroit commercial casino licenses on September 8, 2026, so whichever floor you pick is operating under a current state license.

	MGM Grand	MotorCity	Greektown
Run by	MGM Resorts	The Ilitch family	PENN Entertainment
Opened	1999 (resort 2007)	1999 (hotel 2007)	2000 (hotel 2009)
Hotel rooms	400	400	400
Live poker	Yes	No (closed 2024)	No (closed 2024)
2025 revenue	$605.3 million	$376.1 million	$283.9 million
Share of Detroit revenue	48%	30%	22%

Choose MotorCity for its FanDuel sportsbook, and Hollywood at Greektown if you’d like to walk out into the Greektown restaurant district, which sits on the People Mover line. If you’re weighing the city’s options from home instead, our Detroit online casinos page covers that side.

Taxes on a Detroit Jackpot, or an Online One

Michigan taxes income at a flat 4.25%, and gambling winnings count as income, whether they came from a slot on Third Street or a session online. Ask a tax professional how Michigan treats your losses before you count on deducting them.

The federal side changed in 2026. For payments made in 2026, a slot or keno win triggers a W-2G form at $2,000, up from the $1,200 line that had stood since 1977, and the threshold rises with inflation after 2026. The form is only paperwork, though. According to the IRS guidance on gambling income and losses, every win is taxable whether or not you get one. From tax year 2026, deductible losses are capped at 90% of your losses and can never exceed your winnings.

MGM Online in Michigan: The State-Licensed App

MGM’s own BetMGM app is the state-licensed way to play its brand online, and it works only while you’re physically inside Michigan. Like every online casino, sportsbook and poker room licensed by the Michigan Gaming Control Board, it’s 21+.

The Detroit Floor From Home: What International Sites Offer

Michigan law doesn’t address playing one of these sites from a Detroit apartment. The state’s 2019 online acts are rules for the companies it licenses, and nothing in them, or in federal law, sets out an offense for you at the keyboard. Our guide to online gambling law in Michigan goes further if you want the detail.

The sites we rank are internationally licensed and offer the parts of a Detroit night that travel well: a deep game library, real dealers on camera, and crypto banking in both directions. Here’s how a session there differs from a night downtown:

• Where you play: one browser tab, and the sites keep working when you’re outside Michigan. Our mobile casino guide covers playing on your phone.
• Slots: the game that fills the Third Street floor, without walking the aisles to find a machine. Start with our online slots guide.
• Blackjack and roulette: digital tables in the same tab as the slots. See our online roulette guide for the wheel.
• Live dealers: real people dealing real cards on a video stream, the closest thing to sitting at an MGM table from home. Our live dealer guide shows what’s on offer.
• Deposits: crypto, sent from your own wallet.
• Payouts: crypto, back to that wallet, with no trip to a cashier’s cage.

For the full picture on any one of them, our casino reviews go through each brand in depth.

These are the sites we trust for real-money play from Detroit: established names with full lobbies and cashiers that pay.

Locking Yourself Out, in Person and Online

If you’re driving to Third Street to win back a bad night online, or topping up your crypto balance faster than you meant to, call Michigan’s problem gambling helpline at 1-800-270-7117, or the National Problem Gambling Helpline at 1-800-MY-RESET. The state also offers two separate ways to shut yourself out.

The first is the Disassociated Persons List, which bars you from all three Detroit commercial casinos for life. Since Public Act 225 of 2020, you can apply to come off it after at least five years, but a casino can still refuse you. The list doesn’t reach the tribal casinos, which run their own programs. It also doesn’t cover licensed online play. That’s handled by the Responsible Gaming Database, which you have to join separately even if you’re already on the list. The Gaming Control Board’s responsible gaming page explains how to sign up for each.
