Michigan Online Casino Bonuses & Promo Codes (2025)

Since 2019, Michiganders have been free to access and play at online casinos legally. Players may have to enter bonus codes to unlock and claim the offer to get their hands on an online casino bonus.

If you live in Michigan and are new to online casinos, we’re here to help you navigate this fascinating world and benefit from the many exciting bonuses, promotions, and tournaments that have become such a prominent feature of these entertainment sites. 

We examine how bonus codes can unlock special bonuses and fantastic freebies to boost your gaming experience. 

Online Casino Welcome Bonus Codes in Michigan

We love online casino welcome bonuses. They’re a fantastic way to explore the operator's offerings and extend your time playing online with free spins, bonus funds, and other exciting rewards.

The way you claim your casino bonus will vary from site to site. Not all casinos require bonus codes to activate your welcome bonuses – some offer bonuses just for signing up and making your first deposit. 

Below are examples of welcome bonuses from two of the most popular online casinos in the state.

BetMGM Casino

BetMGM Casino is a big favorite among Michigan casino players. It has an impressive casino lobby and sportsbook markets, with plentiful casino bonuses and rewards for signing up and playing. 

You don’t need a casino bonus code to claim your welcome bonus from BetMGM. Just click the registration link on this page and create your account to be credited with $25.00 in casino cash. Then, when you place your first deposit of $10 or more, you’ll be treated to a 100% deposit match bonus up to $1,000. 

BetRivers Casino

BetRivers Casino is another popular choice with a fantastic welcome offer. You must use the bonus code CASINOBACK when placing your first deposit in your new account. 

The site is another giant, offering Michigan players loads of different bonuses and rewards across its sportsbook and casino sections.

The welcome bonus from BetRivers comprises 24 hours of casino losses back up to a maximum of $500 when you deposit and wager a minimum of $10.

Types of Online Casino Bonuses & Promotions

While we all know welcome bonuses can be some of the most generous among the promotions you’ll find at online casinos, it doesn’t mean the fun stops when you register a new account. Below, we look at the most popular casino bonuses in Michigan:

Welcome Bonus

Nothing beats a friendly welcome when entering a new establishment, and that’s exactly what you get with an array of free spins, bonus cash, and other freebies that operators offer as part of their welcome bonus packages. 

Free Spins 

Free spins are a common casino bonus and can be awarded as part of a wider package or as standalone promotions. Oftentimes, they are in partnership with a particular game developer and are limited to being played on specific slot games. 

Deposit Match

A deposit match is when operators match your deposit value in casino cash or bonus funds. These special prizes cannot be withdrawn and can only be used to place bets. 

Reload Bonus

Reloads are when you top up your account, and the operator rewards you with bonus funds or free spins, often with a value represented as a percentage of your deposit amount. 

Cashback Bonus

Cashback is awarded when you come away from a gaming session with a net loss, and the operator reimburses you a percentage of what you lost. Again, this will be as bonus funds that must be wagered. 

No-Deposit Bonus

A no-deposit bonus is awarded regardless of whether you place a deposit, much like the $25 casino cash from BetMGM mentioned above. These bonuses are far less common than the rest and tend to be lower in value.
