Dive into our DraftKings review for an overview of the app and its features.

Get the scoop on Michigan sportsbook promos this September 2026 and see which bonus types each of the leading Michigan betting apps is offering.

Detroit gets extra preparation time before returning home against the Jets after falling 41-31 at Buffalo on Thursday. The Lions are 1-1, and the defense enters Week 3 looking for improvement after allowing at least 30 points in each of its first two games. Amon-Ra St. Brown has been one of the early bright spots, becoming just the second player in NFL history with at least nine catches and two receiving touchdowns in each of the first two games of a season.

Sunday also brings a familiar face back to Ford Field. Jets coach Aaron Glenn returns to Detroit after serving as the Lions’ defensive coordinator from 2021-24. New York is also 1-1, setting up a matchup between two teams looking to get above .500 before the schedule moves into October.

On the board: Detroit returns to Ford Field for NFL Week 3 against the Jets after splitting its first two games, while Saturday brings two notable Big Ten openers. No. 17 Iowa visits unbeaten Michigan in Ann Arbor, and Michigan State returns home to face Nebraska after dropping its first game of the season at Notre Dame.

The Tigers also spend the entire final week of the regular season at Comerica Park. Detroit hosts Washington for three games to start the week before Pittsburgh arrives for a three-game weekend series, putting six straight home games on the baseball board to close September.

Boosts to know about: BetMGM’s No Sweat Token gives eligible customers some protection on pro football parlays this week. After opting in and applying the token, a qualifying parlay that misses by exactly one leg may return the stake in bonus bets, with individual limits and eligibility shown in the customer’s account. Hard Rock Bet’s The Hundred offers a different type of boost. The sportsbook posts selected straight bets, parlays, and same-game p,arlays at increased odds, but each boosted market disappears after 100 customers have taken it. Michigan bettors can check the sportsbook throughout the week for whatever limited-quantity markets are available around NFL, college football and MLB action.

Weekly Spotlight: BetRivers turns every wager into rewards points

BetRivers’ iRush Rewards gives Michigan bettors three types of points on real-money sportsbook wagers: Loyalty Level Points, Tier Points, and Bonus Store Points. Loyalty and Tier Points determine status and benefits, while Bonus Store Points can be redeemed for rewards, including bonus bets and bonus money.

Sportsbook earning rates also increase with the size of a bet combination. A straight wager earns one point for every $10 wagered, while the rate improves to one point per $6 on two-leg bets, $4 on three-leg bets, $3 on four-leg bets, and $2.50 on wagers with five or more selections.

Getting started with a Michigan sports betting mobile app is a quick and easy process. Just follow these steps to claim top MI sportsbook promos and kick off your betting journey the right way.

1. Pick a sportsbook promo

Michigan offers tons of great welcome bonuses. Take a look at the promos listed on this page and choose one that fits your betting style, whether you prefer a big deposit match or bonus bets up front.

2. Claim your promo code

Click through one of our exclusive links to activate your offer. Some deals apply automatically, while others may need a promo code. Download the app directly from the App Store or Google Play.

3. Create a new account

Fill in details like your name, address, date of birth, and Social Security number. This information is required by law to confirm your identity and maintain security.

4. Verify your identity

Most MI sportsbooks will ask you to upload a photo ID. This step ensures you’re of legal age and physically located in the state, as required for online betting.

5. Deposit funds

To claim your bonus, you’ll need to make a qualifying deposit. Most sportsbooks support secure, fast payment options like credit cards and debit cards, PayPal, Venmo, Apple Pay, and more.

6. Place a bet

Now it’s time to make your first wager. Be sure to check the promo’s terms to make sure your bet qualifies, as some offers require a specific minimum stake or odds.

7. Enjoy your bonus

Your bonus will be credited to your account once your qualifying bet settles or meets the promo criteria. Keep an eye on the expiration window because many bonus bets are only valid for seven days.
