BetMGM Sportsbook allows you to choose between two welcome offers. The signup bonuses are available in all legal states except New York, Nevada, and Washington D.C.

BetMGM Bonus Code TOPTAN1600: Get a 20% Deposit Match up to $1,600 in Sports BonusBetMGM Bonus Code TOPACTION: Get up to $1,500 Back in Bonus Bets if Your First Bet Doesn't Win

A $1,600 deposit match is available with the BetMGM bonus code TOPTAN1600. You can deposit up to $8,000 and BetMGM matches 20% of it in bonus bets. For example, if you deposit $5,000, you'll have $1,000 in bonus bets. You'd also have a 10x wagering requirement, which prevents a withdrawal until you wager 10 times your bonus.

The BetMGM bonus code TOPACTION gives you a $1.5K first bet on the house. You can bet up to $1,500 on any sporting event. If it loses, BetMGM takes your bet and provides a refund in bonus bets. The bonus bets are available for seven days.

The final BetMGM welcome offer is exclusive to North Carolina bettors. Use the BetMGM NC bonus code TOPACTION to earn $150 in bonus bets. The bonus appears in your account following your first $5 wager.

Betting on Wednesday's Sports Slate at BetMGM

We'll look at Wednesday's sports slate for a BetMGM bonus bet. You aren't required to use the bonus on Wednesday, as it's good for seven days. You could use part of your bonus bet on a game today and save some of it for the Final Four on Saturday.

No matter which game you choose, you should aim to use your bonus bet on a plus-money market. Betting on the underdog gives you more expected value, which means you should earn a larger profit over time.

There are plenty of options on Wednesday, including the NBA & MLB. The marquee basketball game of the day features the Thunder vs. Celtics. In this scenario, OKC would be the right play as the underdog.

BetMGM Bonus Bet: Thunder ML (+260)

Boston has been the team to beat all season, but there's been a competitive battle for the league's second-best record. That spot belongs to the Thunder, who hold a slim lead over the Nuggets and Timberwolves.

The odds may not reflect it, but we could see an NBA Finals preview tonight. OKC scored a four-point victory over the Celtics on January 2. Tonight's game begins at 7:30 p.m. ET on ESPN.

The biggest difference between a standard and bonus bet is the stake always goes away with a bonus. If you wager $100 on the Thunder ML, you're looking at a $260 payout.
