Our Top Welcome Bonuses at Michigan Online Casinos for May 2025
Read on for more details regarding what we believe to be the best MI online casino bonuses currently being offer.
Caesars Palace Online Casino
Claim Today!Welcome Offer: 100% Deposit Match up to $2,500 + 2,500 Reward Credits on $25+ Wager
Bonus Code: BONUS2500
- Bonus Details: The Caesars Palace Online Casino bonus is a solid choice for players interested in participating in the excellent Caesars Rewards program, as it offers 2,500 Reward Credits on a $25+ wager. Meanwhile the deposit match bonus offers an appealing maximum but includes a wagering requirement of 15x on slot games, 30x on video poker games, and 75x for all other casino games, and all variations of craps, roulette, baccarat, and Sic Bo are excluded entirely. The bonus expires within 7 days.
- What We Like: Features the largest deposit match bonus among all of the Michigan online casino welcome offers.
- What Could Be Better: The deposit match bonus has a difficult-to-satisfy wagering requirement.
DraftKings Online Casino
Claim Today!Welcome Offer: $35 Casino Credits + 350 Casino Spins on a Featured Game and 24-Hour Lossback up to $1,000 Casino Credits
Bonus Code: Click to claim promo
- Bonus Description: The DraftKings Casino welcome bonus is excellent in that it offers plenty of variety with Casino Credits unlocked immediately upon deposit, in addition to two other unique elements. Even better, at DraftKings Casino, when you receive Casino Credits, you simply have to wager them, and whatever you win becomes withdrawable cash (i.e., they have just a 1x playthrough requirement).
- What We Like: Multiple welcome offers in one, including bankroll-expanding Casino Credits.
- What Could Be Better: The 24-hour lossback component of the welcome offer requires you to deposit and lose money the first day to receive any bonus.
BetMGM Casino
Claim Today!Welcome Offer: $25 on the House + 100% Deposit Match up to $1,000
Bonus Code: SPINSBONUS
- Bonus Description: BetMGM Casino offers one of the few no-deposit bonuses in the state, although be aware that if you win money with it you will have to make a deposit before you can withdraw those winnings. Note also that you cannot use the no-deposit bonus on jackpot slots, poker, or sports. Meanwhile, the deposit match bonus requires a 15x playthrough requirement, expires within 30 days, and holds a larger list of excluded games that can be found in the terms and conditions.
- What We Like: Includes one of the few no-deposit bonuses among Michigan online casinos.
- What Could Be Better: The deposit match bonus comes with a big playthrough requirement and excludes a number of games.
FanDuel Casino
Claim Today!Welcome Offer: Deposit $10, Get 500 Bonus Spins & $40 in Casino Bonus
Bonus Code: Click to Claim
- Bonus Description: The FanDuel Casino bonus’s extremely low requirement makes it absolutely worth claiming. All you have to do is deposit at least $10, and you receive 500 Bonus Spins & $40 in Casino Bonus. The Bonus Spins are a very welcome addition and are available for use on Huff N’ More Puff, a slot that’s exclusive to FanDuel Casino. You’ll have seven days to use the Casino Bonus; you can use it on any game on the site, and whatever you win with it is yours to keep.
- What We Like: Easy, inexpensive way to play, and there is only a 1x playthrough requirement on the Casino Bonus portion.
- What Could Be Better: Other sites have larger welcome bonuses, although those typically have more difficult wagering requirements or other stipulations.
BetRivers Casino
Claim Today!Welcome Offer: 100% of Losses in First 24 Hours up to $500 Back as 1x Bonus Money
Bonus Code: BONUSSPINS; also enter the deposit code PACASINO250 with first deposit
- Bonus Description: The BetRivers Casino rebate-style bonus refunds you back net losses during your first day of play in Bonus Money up to a maximum of $500. You can use the Bonus Money on any games other than roulette, baccarat, craps, or live dealer games within the next 30 days. Also, there’s only a 1x playthrough requirement on the Bonus Money, which means whatever you win with it is yours to keep.
- What We Like: Just a 1x wagering requirement on the welcome bonus.
- What Could Be Better: You must deposit money and be a net loser during your first 24 hours of play in order to receive any bonus money.
Horseshoe Online Casino
Claim Today!Welcome Offer: Get a 100% Bonus Back up to $1,250
Bonus Code: BONUSGOLD
- Bonus Description: The Horseshoe Online Casino offer is extremely straightforward, offering new players a large Bonus Back offer. The best part of the offer, however, that’s absolutely worth mentioning here, is the 1x playthrough on those bonus funds, which makes it a fantastic offer from start to finish.
- What We Like: Large maximum amount, and low playthrough requirements.
- What Could Be Better: Short expiration (5 days) and a relatively large list of specific excluded games (available to view here under Section 9).
Fanatics Casino
Claim Today!Welcome Offer: Get up to $1,000 Back in Casino Credit OR Bet $10, Receive 500 Bonus Spins OR Wager $10, Get $100 Casino Credit
Bonus Code: Click to claim promo
- Bonus Description: We love that the Fanatics Casino offer gives you a choice between three offers. We also like that no matter which one you choose, you only have to wager a minimum of $10 to receive the bonus. Be aware that in either case, you’ll need to wager that $10 within your first 24 hours of creating your account. With the $1,000 Casino Credit, you’ll have seven days to use it once it’s been credited. Meanwhile, the Bonus Spins will be awarded each day for 10 days, and you’ll have to use them on the day you receive them. There’s no additional wagering requirement on either bonus — you get to keep whatever you win with either the Casino Credit or the Bonus Spins.
- What We Like: Only requires a small wager to earn either the Casino Credit or Bonus Spins.
- What Could Be Better: Other sites have larger bonuses, but this is still a nice, easy-to-claim offer.
Golden Nugget Casino
Claim Today!Welcome Offer: Deposit $5, Get 500 Spins on a Featured Game + 100% Deposit Match up to $1,000 in Casino Bonus Funds
Bonus Code: Click to claim promo
- Bonus Description: For the Spins, deposit at least $5 at Golden Nugget Casino, and you’ll get 500 Casino Spins worth $0.08 on a featured game. Meanwhile, the Deposit Match bonus comes in the form of Casino Bonus Funds, which hold a 20x playthrough requirement. For both the spins and the credits, you’ll have seven days to use them, and whatever you win is yours to keep.
- What We Like: Includes a spins offer and a deposit match offer.
- What Could Be Better: Both offers focus on slots players only and aren’t really of benefit to fans of table games or live dealer games, as the deposit match promotion excludes all games except select slots.

Other MI Online Casino Bonuses for New Sign-Ups
- Eagle Casino & Sports — Up to $1,000 Casino Bonus plus 50 Free Spins
- FireKeepers Casino — $500 Bonus Match on First Deposit
- Four Winds Casino — 10 FREE Spins plus four deposit bonuses worth up to $200 total

- SI Casino — N/A
Note that the SI Casino in Michigan is scheduled to be shut down at some point in 2025, which is one likely reason why they don’t currently have a welcome offer. That will open up a new spot among the available licenses, and indications are that Michigan will see a new Hard Rock Bet Casino launch online later in the year.
No-Deposit Bonuses at MI Online Casinos
No-deposit bonuses enable new sign-ups to start playing games right away without having to deposit any funds first. They are relatively uncommon among MI online casino bonus offers, although one of our top recommended sites does have one.
As mentioned above, BetMGM Casino has a “$25 on the House” promo that gives you $25 in bonus money just for creating your account.
The $25 comes in the form of a Casino Bonus and can be used on any games at BetMGM Casino other than jackpot slots. You can’t use the bonus at either the BetMGM Poker site or the BetMGM Sportsbook in Michigan, either. You get seven days to spend it, or else the bonus will expire. If you happen to win anything with the Casino Bonus, you can’t withdraw your winnings until after you make an initial deposit on the site.
Keep an eye out for other Michigan no-deposit bonuses as they will occasionally arise.

Can You Claim Both a Michigan Deposit Match Bonus & a No-Deposit Bonus?
Yes, if an online casino offers both a no-deposit bonus and a deposit match bonus to new players like BetMGM Casino does, you can claim both. Keep in mind, though, that some online casinos that have multiple welcome offers might require you to choose one of them. Also, in some cases online casinos will not let you claim multiple bonuses at once. Be sure to read over the terms and conditions of any bonus offer carefully, so you know exactly what is being offered and what to expect.
Ongoing Bonuses and Promotions at MI Online Casinos

How to Claim a Michigan Online Casino Bonus
Players get bonus money when they sign up for a new account. You don’t have to provide any payment details to receive the bonus, unless of course the bonus requires you to deposit first. Players can claim an offer for every Michigan online casino if they so choose. Follow these steps to claim your MI online casino bonus
-
Follow our links and enter a bonus code
Follow the links on the page including in the table above, and if needed be sure to enter the MI online casino promo code where prompted. All of the bonus codes here at Bonus.com are verified to work for May 2025.
-
Register an account
Follow the sign-up process and enter your details. You’ll be asked for personal information including your full name, email address, physical address, phone number, date of birth, and the last four digits of your Social Security Number. You might have to verify your email address and/or phone number by responding to a message sent to you by the site. You’ll also need to agree to the site’s terms and conditions to complete your registration. Keep an eye out for any prompts along the way to enter your bonus code to make sure you’re eligible to receive the welcome offer.
-
Make a deposit
You don’t have to deposit to claim a no-deposit bonus, but most other welcome bonuses do require you to make an initial deposit into your account, and the sites offer multiple ways to do so. Read through the available options, find a deposit method that works for you, then follow the instructions to provide the needed information to put money in your account. You might keep in mind that later when withdrawing it is usually easier to do so using the same method you used when depositing.
-
Complete playthrough requirements
As discussed above, bonuses often come with playthrough requirements that must be completed in order to receive them. If the bonus has a simple 1x playthrough requirement, that means you simply have to wager all of the bonus money, then whatever you win with it becomes withdrawable cash. Sometimes a bonus will have more substantial wagering requirements, such as some of the deposit match bonuses where you have to wager, say, 15x the bonus amount (with your own money) first before “unlocking” the bonus.
-
Claim your winnings
Once you’ve completed any necessary playthrough requirements and/or satisfied any other conditions associated with the bonus, whatever money you receive becomes yours either to play other games with or withdraw. When withdrawing, be sure to follow the instructions carefully and provide any additional information if necessary. Check out our list of the fastest payout online casinos to learn more about the payout speeds at different sites and for different withdrawal methods.
Types of Michigan Online Casino Bonuses
No Deposit Bonus
There are a few offers available for players looking to play at an online casino without having to put money into account. Some casino operators offer a no-deposit bonus just for creating an account. This bonus usually comes as site credit and must be wagered (i.e., it cannot simply be withdrawn).
Deposit Match Bonus
Deposit match bonuses award bonus money or credits based on the amount a player deposits. These bonuses can double a player’s deposit up to a certain amount, but often come with playthrough requirements. Players can deposit the maximum or make a minimum deposit and still receive the bonus.
Lossback Bonus
Some online casinos extend the opportunity for players to try out the platform and receive their net losses back in bonus money up to a certain time period, usually a 24-hour window. A loss rebate usually comes in the form of site credits with a 1x playthrough requirement.
Bet & Get Bonus
“Bet & Get” bonuses invite you to wager a certain amount on a particular game or game type and receive a bonus in return. An example might be a promo in which you receive a $10 bonus for wagering at least $25 on blackjack.
Free Spins
These types of bonuses offer players the opportunity to earn free spins on slots. They can come in many shapes and sizes, but in all cases, all you need to do is fulfill the bonus requirements, and you’ll receive free spins loaded into a specific game for you to enjoy.
Reload Bonus
A reload bonus is essentially the same as a deposit match bonus insofar as you are being awarded with a bonus for depositing or “reloading” your account with more funds. Typically reload bonuses give you a certain percentage of your deposit amount (e.g., a “50% reload bonus,” a “100% reload bonus.”).
Referral Bonus
Another great opportunity to earn a bonus comes in the form of refer a friend bonuses. These bonuses allow you to utilize a custom referral link to get a friend to sign up for a new account at the site. Usually your friend has to deposit and also wager a certain amount for you to get the bonus, and sometimes your friend will receive a bonus, too.
Loyalty Rewards Bonus
Most online casinos have loyalty rewards programs that give players credits or points for their play that can then be redeemed for bonuses and other prizes and perks. Learn more about different loyalty rewards programs at online casinos here.
Understanding Terms & Conditions for a Michigan Online Casino Bonus
One of the first things you should do when claiming a bonus is to read through the terms and conditions (T&Cs). We know that can be a daunting task, so we’ve run down some things you should look out for below.
One of the most common situations that leads to a missed bonus opportunity is not hitting the required minimum deposit. You may have qualified for the bonus on all other points, but perhaps didn’t deposit the minimum required to earn the bonus. For example, at Fanatics Casino you can deposit as little as $5, but you need to deposit at least $10 to be eligible for their welcome offer.
This is perhaps the most important aspect of bonus terms and conditions, as it can singlehandedly dictate whether a bonus is even attainable. Playthrough requirements, also known as wagering requirements, can range from a 1x playthrough all the way up to a 20x playthrough or more. If you want to clear a $100 bonus that has a 20x playthrough requirement, for example, you’re looking at $2,000 in wagering before you see any withdrawable cash. That may be a lot more than you want to spend.
One of the worst feelings is finally qualifying for a bonus, only to realize that the time period has passed. Often playthrough requirements must be completed within a certain time period (e.g., seven days), and if you can’t meet that deadline you lose the bonus. If you’re planning on signing up at multiple sites to take advantage of multiple welcome offers, you might stagger doing so in order not to have to satisfy a number of different sets of requirements at once.
Finally, make sure you’re playing eligible games that contribute to the bonus playthrough. Slots are almost always eligible, and some Michigan no deposit bonuses are slots-specific. But some are strictly no deposit bonuses for online bingo or other games. If you’re a casino player who only plays blackjack, for example, you’ll want to read the fine print to ensure your favorite game applies to the Michigan casino bonus of your choice.

Michigan Bonus Offers FAQ
Yes, all Michigan online casinos offer a welcome bonus of some kind. A bonus code for new players is as standard as offering slots. These welcome bonuses are used as an acquisition tool to get new players to sign up, and for that reason are often more generous than bonuses offered to existing players.
The amount you can win with your MI online casino bonus is usually not capped, although you should be realistic about how much money you can win from a bonus. If you are awarded a $50 bonus and use it on a slot with a 95% return to player (RTP) percentage, you might win just under that amount or even more than $50. Or you could lose the entire bonus. Don’t make the mistake of thinking of bonus money as equivalent to cash, because it is not.
Yes. As long as you complete any playthrough requirements tied to the Michigan online casino bonus code, you can use your winnings to play other games or withdraw it.
There is currently one Michigan online casino no deposit bonus offer, available at BetMGM Casino. Players can get $50 on the House during signup by using bonus code SPINSBONUS when they register.
No, a Michigan no deposit bonus is rare for existing users. The most common bonuses for existing players in Michigan are bet & get bonuses, reload bonuses, referral bonuses, free spins, and the bonuses they can receive as part of the site’s loyalty program.
