  1. Find an online casino. Getting started at an online casino that best suits your needs is important. You can use our Michigan online casino guide to learn more about each and make your selection. Bonuses can be claimed via the desktop website or by downloading each casino’s app.
  2. If you’re a new player, complete your registration. Make sure to click through using one of our bonus links above or below to receive our exclusive welcome bonuses.

How To Cash Out Online Casino Free Play – 4 Quick Tips

If you followed the above section, by now you’ve received your no deposit and/or deposit match Michigan online casino bonuses. Next, it’s time to clear them and meet all requirements to make them withdrawable. Hopefully, you’ve already read the terms and conditions as recommended in step four of the above section. If you haven’t, read them now.

1. Deposit the Minimum

In every deposit match bonus terms and conditions, there will be a minimum deposit requirement. Usually, this sits around $10, but numbers may vary so make sure to always check before you make that first deposit. This step is simple — just ensure that you’re hitting the minimum deposit.

2. Complete Playthrough Requirements

Once you’ve made your deposit, you’ll notice that every bonus comes with a playthrough requirement, which is how many times you need to play through those bonus funds to convert them to withdrawable cash. For example, if you have $100 in bonus funds that require a 5x playthrough, you’ll have to wager $500 to convert them to cash and withdraw.

3. Complete Before the Expiration Date

Every bonus comes with an expiration date that can range anywhere from 7 days up to 30 days or more. One of the worst things you can do is let your bonus expire, so make sure to keep this time limit in mind when playing through. This will always be clearly stated in the terms and conditions.

4. Make Sure You’re Playing Eligible Games

Some bonuses, such as Golden Nugget’s 200 free spins, are only available on certain eligible games. These games will always be listed in the terms and conditions. In the case of Golden Nugget, the games are 88 Fortunes and 88 Fortunes MEGAWAYS, so always make sure you’re playing the stated eligible games.

Once you’ve successfully converted your bonus to real money, that’s all there is to it. The rest of your journey is up to you. You can keep the funds in your account and continue to play, or you can withdraw them by using cashier options such as ACH/eCheck, PayPal, or prepaid cards, amongst others.

Online Casino Bonus Balance Explained

Your Michigan online casino bonus balance will be separate from your real money balance. As you complete playthrough requirements as explained above, that bonus balance will be worked into your real money balance.

In most cases, when you play, your bonus balance will be utilized first and your real money balance second. While the bonus balance can’t be withdrawn, it does count as extra funds in your account that can be used on your favorite games.

Types of Online Casino Promotions

Michigan online casino promotions come in many shapes and sizes. Now that you know the best bonuses, where to find them, how to claim them, and how to clear them, we’ll go into more detail about what you’ll typically see offered. If you haven’t yet read the section above on “How To Cash Out Online Casino Free Play”, we highly recommend you do so before learning more about the below bonuses. This is because they all will contain various requirements in the terms and conditions, from making sure you’re playing eligible games to requiring certain playthrough rates.

Once you’ve read about how to cash out your bonuses, it’s time to dive into the different types of bonuses below.

No deposit bonuses are very appealing as they don’t require any deposit to earn. That being said, they are almost always smaller than other varieties of bonuses. We’ve got a full page on Michigan online casino no deposit bonuses for you to learn more.
Deposit matches are arguably the second most common Michigan online casino bonus available. You’ll see many of them offered on our table of bonus codes for new players at the top of this page, and chances are you’ll see them offered frequently as Michigan online casino promotions for existing players as well. The idea is simple — make a minimum deposit and you’ll receive a certain percentage of your deposit as bonus funds. Take, for example, the Caesars Casino promo code, which gives new players a 100% deposit match worth up to $2,000. If you deposit $2,000, you’ll receive $2,000 in bonus funds. For existing players, the deposit match amounts are usually around 20%. So, for example, if you opt-in to an existing player promotion that offers a 20% deposit match and make a $100 deposit, you’ll receive $20 in bonus funds (depending on the bonus limits).
Free spins bonuses are more commonly offered for existing players, and they’re also quite straightforward. Basically, you complete a certain task and receive a certain amount of free spins to be used on a select game. This task can be wagering a certain amount on a specified game, depositing a certain amount, etc. No matter what that task is, you’ll earn free spins once you complete it as long as you’ve opted-in to the promotion. One example of free spins for new players is the Golden Nugget bonus code, which offers 200 free spins on 88 Fortunes or 88 Fortunes MEGAWAYS when you make a minimum deposit of $30.
Cashback deals are plentiful for new and existing players alike. In most cases, they entail receiving a percentage of your net losses back as bonus funds. It’s important to read the terms and conditions for all bonuses, but especially cashback deals, as they usually have game restrictions. An example of a cashback deal for new players is the FanDuel Casino promo code, which offers a $2,000 play-it-again day. In this case, FanDuel will refund your first-day net losses up to $2,000. For existing players, cashback deals usually look something like a 20% cashback on net losses on a certain game. So, if you play the select game and end up losing $100, you’ll receive $20 back in bonus funds. Keep in mind that these types of Michigan online casino promotions, even if they’re 100% cashback, are not risk-free as the bonus funds you receive back have a playthrough requirement before withdrawal.
A reload bonus is essentially another term for a deposit match bonus that’s exclusively available to existing players who have already made their first deposit. Much like a deposit match bonus, you’ll receive a certain percentage of your deposit in bonus funds. So, if you were to opt-in to a 20% reload bonus and deposit $100, you’ll have $120 to play with, $20 of which is bonus funds.
Prize pool tournaments are exactly what they sound like. An online casino will put up a pool of prizes — this can consist of physical prizes such as electronics, bonus money prizes, or even trip packages. Check terms and conditions to find out how to participate. Participation usually involves wagering on a select pool of games. The more you wager, the more chances you have to win a prize in the prize pool.
Game of the week promotions put the spotlight on a specific game, and that game is almost always a slot. Players must wager a certain amount on that game to receive a reward. That reward can range from Michigan online casino free play in the form of bonus funds, double loyalty program points, or free spins on the same or another slot.
While most common at social and sweepstakes casinos, there have been known to be Michigan online casino bonuses that offer daily log in deals. These are exactly what they sound like. Log in each day to receive a bonus, usually in the form of free play or free spins.
Crossover bonuses are great for players who like to dabble in more than just the online casino world. These bonuses are offered by casinos that also offer their own sportsbook or online poker platforms. At their most basic, you must complete a casino task to receive a sports or poker bonus, or vice versa. For example, BetMGM often offers bonuses that will reward a sportsbook free bet for wagering a certain amount on a casino game. On some sites, you could earn free entry into poker tournaments for wagering a certain amount on their casino platform.

My Michigan Online Casino Bonus Isn’t Working. What Do I Do?

Before we get to the point of needing to ask this question, always make sure you first use our exclusive Michigan online casino bonus links and/or enter your bonus code. Also, always double-check the terms and conditions to ensure all requirements are being met.

If you’ve done the above, the next step is to reach out to customer support. Every legal Michigan online casino will offer customer support and various ways to contact them. You can find the best contact methods in each individual casino’s help section.

Is It Always Worth It to Claim Bonus Codes at a Michigan Online Casino?

Yes and no. If you’re already planning to play at an online casino and the bonus matches what you like to play as well as your style of play, claiming your Michigan online casino bonus code is a no-brainer, especially if it’s a no deposit bonus.

On the other hand, if the bonus doesn’t match what you like to play or how you like to play, you should skip it. The most important part of playing online is playing responsibly, and that means you should never play out of your comfort zone just to claim or clear a bonus. If you do play out of your comfort zone, no matter how enticing the bonus may be, you won’t have a good time. And, in the end, playing at an online casino should be all about having fun.
