How to claim the BetMGM bonus code

The BetMGM bonus code CBSSPORTS provides a different offer depending on the state you're in, but the code is the same. Users in Michigan, New Jersey, Pennsylvania and West Virginia can sign up and partake in the "bet and get" offer for $150 in bonus bets if a first bet of $10 or more wins. Users in other states where BetMGM is available can get up to $1,500 in bonus bets, but only if their first bet loses. With this offer, BetMGM returns a user's stake from their first wager in bonus bet form if it loses. So if you bet $1,500 on the Cubs to beat the Brewers and Milwaukee wins, you'd get $1,500 in bonus bets credited to your account. There's no minimum odds requirement for either BetMGM welcome offer.

BetMGM bonus code terms and conditions

Only new users who have never made a BetMGM Sportsbook account before are eligible to use the BetMGM bonus code CBSSPORTS. New users must be both 21 or older and located in a state where BetMGM is available. This promo can be used on any of the MLB or WNBA games today.

If you sign up with CBSSPORTS for the up to $1,500 in bonus bets promotion, the amount you wager for that first bet dictates how your bonus bets are credited. If you bet under $50 and lose, you get a single bonus bet slip worth your original stake. If you bet $50 or more and the bet loses, you get five bonus bet slips that are each worth 20% of your initial wager. So if you bet $1,500 and lose, you'd get five bonus bet slips each worth $300.

Bonus bets can't be withdrawn as they hold no cash value and they expire after seven days. If you win a bet with bonus bets, you get the winnings but not the stake. Sign up with BetMGM to get bonus bets here:

Best bets on Wednesday, August 20

Best MLB bets today

The New York Mets have struggled since the All-Star Break, but they got a much-needed series win over the Seattle Mariners over the weekend and started their series against the Washington Nationals with an 8-1 win on Tuesday. New York can win its second straight series with a win on Wednesday while Washington will look to even things at 1-1 before tomorrow's series finale. Kodai Senga (7-4, 2.35 ERA) goes for the Mets while Brad Lord (3-6, 3.26 ERA) starts for the Nationals. Senga hasn't been working deep into games since coming off the injured list, but he pitched into the sixth inning in his last start when he allowed two runs to the Atlanta Braves over 5 2/3 innings of work. As for Lord, he's quietly been one of the better rookie pitchers in baseball this year and pitched well his last time out, allowing two runs to the Philadelphia Phillies across six innings in a Washington win. The SportsLine Projection Model, which simulates every MLB game 10,000 times, sees value in backing Washington on the money line at +143 odds as the Nationals win this game in 48% of model simulations.

The Padres had a chance to take full control of the National League West over the weekend, but they were swept by the Los Angeles Dodgers. San Diego fell to San Francisco on Monday before bouncing back on Tuesday and now will look to secure, at worst, a split of this four-game series that ends on Thursday. Right-hander Landen Roupp (7-6, 3.45 ERA) starts for the Giants while the Padres will start JP Sears (7-10, 5.12 ERA). Roupp has pitched well in his first full MLB season after spending more time in the bullpen in 2024, but his last start was a rough one as he allowed five runs in three innings to the Rays. Sears joined San Diego at the deadline in a trade with the Athletics, and he allowed five runs in five innings against the Arizona Diamondbacks his last time out. The SportsLine Projection Model is backing the Padres on the money line as they win in 62% of simulations, returning value at -156 odds. Bet on this MLB game and more at BetMGM:

Best WNBA bets today

There's only one WNBA contest on Wednesday when the Wings visit the Sparks. It's been a rough season for Dallas, which is just 9-26 on the year, the worst mark in the Western Conference and third-worst record in the league. Los Angeles is 16-18 and needs to build some momentum to push its way up the standings if it wants to make the postseason. WNBA expert Max Meyer has shared his WNBA best bets for Wednesday, and he's targeting rookie Paige Bueckers' points prop line of 18.5. Bet on WNBA games at BetMGM:
