What Bonuses Are Available at Michigan’s Legal Online Sportsbooks?

Bonus Bets or 'Second Chance' Bets

New players at many US legal online sportsbooks can take advantage of bonus bet promotions. A second chance bet offer refunds a player on the first bet after a deposit up to a given amount.

A lost bonus bet is usually refunded in one of three ways:

  • Site credits
  • Multiple bonus bets
  • Single bet of equal value 

The bets usually need to be placed on wagers with odds of -200 or longer. Other terms and conditions will apply as well.

Deposit Match Bonuses

Players venturing into the world of legal US online gambling sites will notice the deposit match bonus as a commonly offered sports betting promotion. Deposit match bonuses award bonus money based on a percentage of a player’s deposit amount.

BetRivers Michigan offers new players one of the most generous deposit match bonuses in the industry. The sportsbook offers a 100% deposit match bonus, up to $500, with just a 1x playthrough requirement.

This playthrough requirement is commonly 5x to 30x the amount of the original deposit. The BetRivers bonus, however, stands as one of the most player-friendly offers in the industry. Use this link to claim today.

What Sports Can I Bet On At Michigan Online Sports Betting Sites?

The arrival of legal sports betting in Michigan opens up an entirely new world of possibilities, in a state with a rich professional sports tradition.

Detroit is on the shortlist of US cities that host teams from all four major US sports leagues.

The NFL’s Detroit Lions, the NHL’s Detroit Red Wings, the NBA’s Detroit Pistons, and Major League Baseball’s Detroit Tigers are at the heart of one of the most passionate sports fan bases in the US. Both DraftKings and FanDuel announced partnerships with the Detroit Pistons to become their preferred sportsbooks.

Michigan’s legal online sportsbooks present opportunities to wager on all of those teams. Virtually every game on the regular and postseason schedule in the four major sports is open for betting to Michigan players.

Ways To Bet On US Pro Sports In Michigan

There are several ways to bet, including moneyline and point spread betting on single contests, as well as parlay betting on multiple games.

Michigan’s legal online sportsbooks offer futures betting markets on all of the major US sports leagues. Prop bets on events like the NBA draft and the Super Bowl open up even more betting options for Michigan bettors.

In addition to the four major sports leagues, MMA, boxing, golf, tennis, NASCAR, and a host of other US sporting events are available to bet from Michigan’s legal online sportsbooks.

Michigan’s professional sports tradition is equaled by the legacy of major college sports in the Wolverine State.

The Michigan Wolverines and Michigan State Spartans rule the college sports landscape in the state. State residents divide their loyalties between these two programs.

College Football

The Wolverines and the Spartans play in the Big Ten Conference, the longest-running college sports conference in the US. The Michigan versus Michigan State football rivalry goes back more than 100 years.

Both programs are perennial powerhouses in the modern era of college football. The annual rivalry game between the two is one of the biggest in-state contests of the year.

Michigan and Michigan State also matchup annually against other Big Ten rivals like the Ohio State Buckeyes, Iowa Hawkeyes, Wisconsin Badgers, and Penn State Nittany Lions. These Big Ten rivalry games are perennially some of the biggest games on the college football calendar.

College Basketball

The Michigan versus Michigan State rivalry is equally tense in college basketball. Both programs lay claim to elite status in the national landscape.

And unlike in other states, you can bet on in-state Michigan schools in Michigan. In places like Iowa and Illinois, betting on in-state schools is restricted.

The Big Ten stands as one of college basketball’s top conferences year after year. The conference offers a loaded schedule of big games for Michigan bettors.

The Wolverines and Spartans match up annually against teams like Ohio State, Penn State, and Wisconsin. Other traditional Big Ten powerhouses include the Indiana Hoosiers, Illinois Fighting Illini, and conference newcomer Maryland Terrapins.

Other College Sports

College baseball, softball, hockey, lacrosse, and others are open for betting when Michigan’s legal online sportsbooks go live. The Lawful Sports Betting Act allows for betting on college sports with no restrictions.

Michigan’s legal online sportsbooks aren’t just be limited to US professional and college sports. Fans of soccer, rugby, cycling, and other international sports leagues will enjoy a comprehensive menu of betting markets.

International Soccer Leagues

The English Premier League features clubs like Manchester United, Liverpool, Arsenal, and Manchester City. Massive worldwide fanbases follow these teams, creating some of the world’s biggest sporting events when they face off against each other.

You can also find UEFA Champions League, Europa League, and international teams listed at most major online sportsbooks.

Other major international soccer leagues, like the German Bundesliga and Spanish La Liga, are open for betting for Michigan players on the state’s legal mobile sports betting sites.

Other International Sports

Major cycling events like the Tour de France are offered for betting at Michigan’s legal online sportsbooks. Tennis majors like Wimbledon and the Australian Open, as well as golf events like the British Open and Ryder Cup, are also on the menu for Michigan bettors.

International leagues and events in rugby, cricket, basketball, baseball, and auto racing add even more to the betting menus in Michigan.

What Else Can I Bet on in Michigan?

Michigan’s online sportsbooks offer betting on competitive chess, darts, table tennis, and other non-traditional sports and games. With Michigan’s legal online sports wagering sites live in the state, these betting markets are open to in-state bettors.

Michigan’s Online Sportsbook Apps

Michigan’s sports betting platforms offer access through mobile apps, as well as on a desktop computer. Online sports betting mobile apps are optimized for Android and iOS devices. This makes the mobile betting experience intuitive and convenient.

Legal mobile sports betting apps use geolocation technology to determine a user’s location at the time of use. These apps are open to anyone in the state of Michigan, as long as they’re 21 or over and located within state borders.

The ease of access and convenience of mobile sports betting has made it the method of choice for bettors in New Jersey and Pennsylvania. Those two states represent two of the biggest sports betting markets in the US. In both states, mobile wagering makes up more than 80 percent of the total statewide sports betting handle. Find out more about New Jersey Sportsbook Promos, PA Sportsbook Promos and Massachusettes Sports Betting Promos by clicking the links.

iOS Mobile Sports Betting Apps

Platforms like BetRivers, Caesars Sportsbook, FanDuel Sportsbook, and BetMGM are all live in Michigan. All of these online sportsbooks are available as apps for iOS devices.

These apps can be found in the App Store on iOS devices. Downloading the apps is free, and can be done from anywhere within state borders.

Android Mobile Sports Betting Apps

Nearly all of the platforms available as iOS apps are accessible as apps for Android devices as well. Android users looking for online sportsbooks like Caesars Sportsbook and BetRivers are in luck.

The Google Play store just recently began listing online gambling apps. That means your sportsbook of choice might be listed and it might not be. If it’s not, you can always download it directly from the sportsbook’s website.

If you’re downloading from the Google Play store, make sure it’s the Michigan version of the app. For example, BetRivers Michigan and BetRivers Iowa are two different platforms.

What Do I Need to Create an Online Sportsbook Account in Michigan?

New players can start betting in just a few easy steps at Michigan’s online sportsbooks:


Download the Mobile Sports Betting App

Start by choosing the sportsbook you’d like to play on and downloading its app. If you can’t find the app in the App Store or the Google Play store, visit the sportsbook website for a direct link to the download.



Click “Join Now” and complete the required fields for name, birthdate, valid email address, and username of choice. You’ll also need to enter the last four digits of your SSN for identity verification purposes. If you’d like to claim a new player welcome bonus (and we highly recommend you do so), here’s where you can confirm that the promo code has been entered and/or the exclusive signup link has worked properly.


Deposit and Bet

After your account verification has been completed, including email and document verification, navigate to the cashier to deposit and begin betting. We recommend choosing a deposit method that you’re also happy to withdraw back to when the time comes for ease-of-use.

Beyond that, find your bets, good luck, and have fun.

Neighboring States with Legal Online Sportsbooks

Two of Michigan’s three neighboring states offer excellent sports betting markets:

Wisconsin also has sports betting, but it’s monopolized by two state-run sportsbooks, which makes the odds pretty uncompetitive, especially compared to Michigan.

Legal Versus Illegal Online Sportsbooks

Michigan players now enjoy unprecedented access to legal sports betting. The number of different platforms slated for Michigan operations offers bettors the opportunity to line shop and find bets among multiple outlets.

Michigan’s Regulated Casino Industry

The National Indian Gaming Commission operates as the governing body that regulates Michigan’s tribal retail casinos. The Michigan Gaming Control Board oversees the state’s commercial casinos as well as all online gambling in the state.

This is a high level of regulatory oversight from multiple governing bodies. That means placing a bet at a legal online sportsbook in Michigan offers the same level of security as placing that same bet in one of the state’s land-based casinos.

Risks With Offshore And Illegal Gambling

Offshore gambling sites operating in the US are not obliged to offer these same safeguards. Betting at an offshore sportsbook entails a much higher level of risk. This includes the possibility of depositing money and never seeing that money again.

These offshore gambling sites are illegal operations in the US. As such, playing on them could result in a criminal penalty for players.

Michigan Online Sports Betting FAQs
