Eligibility for MI Online Casino Promo Codes

Promo codes are exclusive codes that activate a bonus when you input it to the casino. Anyone who has a code can use it as long as they meet the bonus conditions (like making a deposit) and can legally gamble online.

In Michigan, you can legally gamble online if you:

Once you meet the above conditions, not only can you legally gambling for real money, but you can also claim any number of Michigan online casino bonuses using a promo code or by opting-in directly at the casino.

Wagering Requirements in Michigan

Like all casino bonuses, those you’ll access using a Michigan casino promo code come with specific terms and conditions that need to be met to make the most of the free money or reward. The most important to know and understand (as it can affect the worth of your bonus) is the wagering requirement.

A wagering requirement is set on a bonus when the casino gives you cash. It stops you from doubling your money and withdrawing instantly without playing, as this wouldn’t be very fair for the operator, who wants a chance to win their money back.

A wagering requirement is expressed as a number, like x10. To calculate the wagering requirement, you need to multiply the bonus amount by the number, then play this amount to be eligible to withdraw any bonus money or winnings made with bonus money.

However, if you’re happy keeping your money in the casino and not withdrawing (or if you don’t win anything), you don’t need to meet this condition.

Let’s use an example to demonstrate it better. Take Golden Nugget Casino, MI; they’ve got a sizable welcome deal that offers new players a 100% cash match up to $1000 with 10x wagering requirements.

Slots are eligible 100%, and tables contribute 25% to the wagering requirements (play slots and every $1 count as $1 off the wagering requirements, but play table games and only 25c is contributed). Golden Nugget applies the wagering requirement to the deposit and the bonus amount (this is not always the case, some gambling sites state that it applies only the bonus amount).

So let’s say you take the deal and deposit $200. The site gives you $200. Your total bankroll is $400. You play, hitting the jackpot, and want to withdraw. Before you can, you must meet the wagering requirement: $400 x 10 = $4,000.

Let’s compare it to BetRivers, which offers a 100% match up to $250 with 1x wagering requirements. You decide to make the same deposit of $200, and the casino matches you, equalling a $400 bankroll. You win and want to withdraw. At this casino, you can as long as you’ve spent the $400 bonus money once.

From the two examples, it’s clear how wagering requirements can change the value and usability of Michigan online casino bonuses. This is why comparing terms and conditions or getting an expert opinion on casinos and bonuses is essential.

Generally, the lower the wagering requirements, the better, but you also need to consider your budget and the size of the bonus you want to achieve, as well as the game eligibility and contribution percentage.

Wagering Requirement Example

To help you beat the odds, here’s an example of how you can use a wagering requirement to make the most of a bonus.

Wagering requirements can’t be ignored, unfortunately, without renouncing your bonus. However, you can get around them by looking for a bonus that features no wagering requirements - such as cashback, or a wager-free welcome bonus.

For example, if a casino is offering a cashback bonus, you should look to see if the amount offered is equal to the minimum wager. If so, you’re in luck! If multiple bonuses are on offer and none offer a like-for-like return, prioritise those that offer the most bang for your buck.

How do Promo Codes for MI Casinos Work?

MI casino promo codes are a series of letters and numbers, like CASHMATCH250. When you input a valid promo code into the casino, either during signup or when making a deposit, it tells the site that you are eligible for the corresponding bonus deal.

You can use a bonus code for any type of Michigan casino bonuses, including a welcome deal, no deposit bonus, free spins, reload deal, and more. It purely depends on what the operator has programmed the code to do!

If you’re unsure how to use a MI bonus code or join an online gambling site, follow these steps:

  1. Pick any of the Michigan online casino promo codes given on this page.
  2. Click the link to go directly to the casino’s registration page.
  3. Complete the form with your personal data.
  4. Input the bonus code when prompted.
  5. Confirm the registration.
  6. Head to the cashier and make a deposit.
  7. Wait to receive your welcome bonus.


Can I use more than one MI online casino promo code?

You can use more than one MI online casino promo code, but it can’t be for the same type of bonus. For example at BetMGM, you can only take one welcome deal at most gambling sites, so you can only use one welcome deal BetMGM promo code.

Of course, if you want to join two different sites, you could claim a welcome deal at both sites, and after the welcome offer, you can use promo codes for all kinds of gambling bonuses, but you can only use a code once.

How possible is it to win with MI online casino promo codes?

The short answer to this is yes. A promo code simply gives you one of the latest bonuses. You then use the bonus to play. The games you’ll use the bonus on are the same as if you’d loaded up your account directly and are tested for fairness to make sure they payout.
