Michigan has all the ingredients needed for a healthy sports betting bonus landscape. Low taxes, lots of competition, and consumer protection laws that specifically address sportsbook promotions all make Michigan a good place to be for the value-minded bettor.

State law requires all promotions to be fair and non-predatory, but the best Michigan betting bonuses stand above the rest in terms of value. Free bets, deposit bonuses, and risk-free wagers are just a few of the many options bettors have at hand in Michigan.

We begin this page with a summary of the best Michigan sportsbook bonuses. We will continue below with more information on how they work, the latest promo codes, and how state law regulates promotions.

Most Michigan betting sites do not require bonus codes for new customers to claim a welcome offer. In most cases, bettors receive bonuses automatically upon registration and deposit.

Some sportsbooks do ask for bonus codes or promo codes upon signup or deposit, but even in these cases, customers can usually just leave them blank.

Sportsbooks typically ask for promo codes not to award bonuses but to track their marketing campaigns. A sportsbook might list different bonus codes in various marketing media (such as online ads, billboards, radio ads, etc.) and see how each campaign performs based on the number of times each unique code was input by new customers. Usually, it does not matter at all which code a customer inputs.

If a sportsbook does require a bonus code, we note that on this page (see the welcome offers listed above).

How to Evaluate the Value of a Sports Betting Bonus

The best Michigan betting bonuses are easy to understand because they are not bound by excessive terms and conditions. Every deposit bonus, refund guarantee, and free bet comes with limitations, but the best offers keep limitations to a minimum and avoid confusing language.

One of the most important things to keep in mind is that the size of a bonus has no relation to its quality. The biggest welcome offers in the world can be negated by burdensome terms and conditions or excessive wagering requirements. Likewise, smaller bonuses sometimes provide the most value because they are easy to claim and clear for withdrawal.

Knowing how to evaluate the quality of any particular bonus comes down to understanding how the most common types of offers work and what to look for in the terms and conditions.

Types of Sportsbook Promotions in Michigan

Michigan betting bonuses and welcome offers tend to come in one of several flavors. There is an endless variety of variants, but new bettors can generally expect to find welcome offers that fit into the following categories.

Deposit Match Bonuses

The standard deposit match bonus offers new customers cash or site credit in return for funding their accounts. The size of the deposit determines the bonus’s size, typically at a percentage ranging from 50% to 200%.

For example, a 50% bonus would give an extra $100 to a new user who makes a $100 deposit.

Similarly, a 100% bonus would give an extra $200 to a new user who makes a 4200 deposit.

Sportsbooks usually word these bonuses something like “100% up to $500,” which tells new customers they can get up to $500 extra.

Free Bets

Free bets are issued either as standalone welcome bonuses or in conjunction with other promotions. A bettor who receives a free bet may use it to place a wager on any sport and keep the winnings.

Free bets come with two limitations. First, they may not be withdrawn. Second, the free bet is not returned with any winnings. If a customer places a $100 free bet on a bet with even odds and wins, that customer will receive a payout of $100 rather than $200 (because the free bet is not returned).

One thing to look for in a free bet is whether the winnings are subject to wagering requirements. The best free bet promos allow users to keep or withdraw their winnings with no further wagering required. Less desirable free bet promos force customers to place additional wagers to withdraw their winnings.

Risk-Free Bets

Risk-free bet offers guarantee that a customer’s first bet will be refunded if it is a loser. If the customer wins money with the wager, the winnings are paid as normal. If the customer’s first bet loses, the sportsbook issues a refund of equal size up to a predefined maximum amount.

Most sportsbooks issue risk-free bet refunds as site credit, which somewhat invalidates the label “risk-free” since customers cannot withdraw site credit. However, any winnings won with site credit are withdrawable.

No-Deposit Bonuses

No-deposit bonuses give new users free bets in return for signing up with no deposit necessary.

In the vast majority of cases, customers may only withdraw the winnings from a no-deposit bonus. In some cases, even the winnings are restricted from withdrawal until the customer makes a deposit.

Ongoing Promotions for Existing Customers

Competition among sportsbooks does not end at attracting new customers. The ease of leaving one mobile sportsbook for another incentivizes operators to continually engage their existing users with additional promos to encourage loyalty.

Some sportsbooks are endlessly creative in designing ongoing promotions for customers, so it would be impossible to list all the many types here. Below are descriptions of some of the most common types of offers.

  • Odds Boosts: The sportsbook increases the odds on a specific wager, often for markets involving popular events or teams based in Michigan. For example, an odds boost might bump the odds on a team to win its next game from +110 to +170.
  • Enhanced Parlay Payouts: The sportsbook boosts the payout odds for winning parlays by a certain percentage. In many cases, the more legs a customer adds to his parlay, the bigger the payout boost.
  • Free Bet Promos: The sportsbook offers free bets (site credit) to customers who take certain actions such as placing an in-play bet, liking a post on social media, and so on.
  • Second Chance Pointscorers: In this promo, the sportsbook refunds customers who bet on the first player to score points if the chosen player fails to score first but still scores at any point during the game.
  • More When They Score: This is a fun promotion in which the customer picks a team to win its next game and then receives cash or free bets for every touchdown, run, or goal their team scores during that game.
  • Overtime Loss Refund: The sportsbook refunds customers’ bets if their teams lose in overtime.
  • Reload Bonuses: Reload bonuses work like welcome bonuses but are extended to existing users. Sportsbooks often issue reload bonuses for a limited time, such as one week.

Important Terms and Conditions to Understand

It is critical that bettors understand how to interpret the terms and conditions attached to any bonus offer. The terms and conditions make or break every bonus.

A bonus that looks great at first glance can lose a lot of its value if it includes unfavorable terms. Similarly, a promotion that looks “just OK” at first may be one of the best on the market if it comes minimal strings attached.

Every offer comes with terms and conditions, so it is essential to understand what to look for when evaluating a bonus. Some of the most common terms bettors should note include the following:

  • Wagering requirements: Many promotions and most deposit bonuses come with wagering requirements (a.k.a. “rollover”) that restrict withdrawals until the customer has wagered X amount in dollars. The amount varies but is often expressed as a multiple of the bonus or deposit amount. For example, a $100 bonus with a 5x rollover indicates the customer must place $500 worth of wagers before withdrawing.
  • Withdrawal restrictions: It is important to know if customers may withdraw the bonus money or just the winnings as this distinction impacts the real value of any offer.
  • Minimum betting odds: The minimum odds provision is sneaky and easily overlooked. If an offer says something along the lines of “this offer may only be used on markets with odds of -200 or greater,” it explains wagers with odds of -250, -300, and so on are incompatible with the offer. Wagering requirements also often come with minimum odds provisions (i.e., “only wagers placed at odds of -300 or greater count toward this offer’s rollover”).
  • Bonus excluded from winnings: Free bets and other site credit offers usually explain in the terms that the bonus money is not included in the payment of any winnings. In this case, only the net profit of any winning wager placed with bonus money is returned to the customer as cash.
  • Expiration: All bonuses have an eventual expiration date, whether that’s a few days from now or months down the line. Key items to look for are how long customers have to claim a welcome offer after signing up and how long any free bets or site credit remain usable.

Michigan Law on Sports Betting Promotions

Michigan law regulates promotional offerings to protect consumers from unfair or deceiving practices.

As a result, most Michigan betting bonuses are simple in nature and non-predatory. Not all promotions are great, but outright scams will be rare for as long as the Michigan Gaming Control Board (MGCB) oversees the industry.

R 432.749 of the MI sports betting regulations deals with promotions, advertising, and loyalty programs.

The key provisions related to betting promotions read as follows:

(2) A sports betting operator or internet sports betting platform provider may conduct internet sports betting bonus and promotional wagering offers subject to all of the following:

(a) A sports betting operator or internet sports betting platform provider must maintain a record of all bonus and promotional wagering offers related to internet sports betting in an electronic file that is readily available to the board.

(b) All bonus and promotional wagering offers must be stated in clear and unambiguous terms and must be accessible by the authorized participant after the offer is accepted and before completion.

(c) Offer terms and the record of all offers must include all of the following at a minimum:

(i) The date and time the offer is active and expires.

(ii) Authorized participant eligibility, including any limitations on participation.

(iii) Any restriction on withdrawals of funds.

(iv) Wagering requirements and limitations on events or wager types.

(v) The order in which funds are used for wagers.

(vi) Eligible events or wager types.

(vii) Rules regarding cancellation.

The rules further state that sportsbook operators must provide an easy and conspicuous method for customers to cancel participation in promotional offers that come with wagering requirements. Operators are also prohibited by law from limiting winnings earned while participating in an offer.

Frequently Asked Questions

Do retail sportsbooks at casinos offer betting bonuses?

Sports betting bonuses are almost exclusively limited to mobile sportsbooks. Retail sportsbooks at casinos have little incentive to provide welcome bonuses to customers because gamblers tend to pick land-based casinos based on location, emphasizing convenience.

Retail sportsbooks may run loyalty programs and host other promotions on occasion, but welcome bonuses are rare.

Online sportsbooks are not limited by geographic reach, but they also face much more competition and must work that much harder to stand out from the pack. Welcome bonuses play a prominent role in online betting, which is a good thing for gamblers.

How can I tell if a particular bonus is a good deal?

The best way to analyze the value of any promotion is to read the terms and conditions with particular attention paid to wagering requirements.

Bonuses that come with no wagering requirements are usually an excellent value for customers. Bonuses with wagering requirements of 1x to 5x are a pretty good deal in most cases. Wagering requirements in excess of that warrant proceeding with caution and possibly moving on to a different offer.

Are no-deposit bonuses legitimate?


No-deposit bonuses are nice in that they allow the customer to test drive a sportsbook without the trouble and expense of making a deposit. However, many no-deposit bonuses require a deposit before any winnings may be withdrawn, which negates any idea that these are the equivalent of “free money.”

How can sportsbooks afford to give so many bonuses?

Large companies with big marketing budgets run nearly all mobile sportsbooks. They write off some of the expenses incurred by offering bonuses as a cost of doing business. Simply put, they can afford it.

Sportsbooks also recoup some of the cost by enforcing wagering requirements on larger bonuses. Additionally, operators know exactly how much each new customer is worth on average and are willing to spend X money per new signup to ensure a long-term profit.

Who qualifies to receive a sports betting bonus?

Generally, customers who are 21 or older and physically located in Michigan qualify for the bonuses discussed on this page. Some offers are restricted to new customers only while others are extended to everyone.
