BetMGM Bonus Code SIBONUS50: Bet $1,500 on NBA & NHL Playoffs, MLB Games
Use the BetMGM bonus code SIBONUS50 to claim a $1,500 First Bet offer ahead of Wednesday's packed sports slate. A code is required -- enter SIBONUS50 at sign-up. New users can bet on Cavaliers vs. Pistons Game 5, Avalanche vs. Wild Game 5, or any MLB matchup this May 13 and get bonus bets back if their first wager loses. Check out more sportsbook promos for today's action.
How the BetMGM bonus code SIBONUS50 works for NBA playoffs and NHL playoffs betting
The BetMGM bonus code SIBONUS50 unlocks two welcome offers depending on your state. Most new users across eligible states receive the $1,500 First Bet offer, while new users in MI, NJ, PA, and WV can choose a Bet $10, Get $150 in bonus bets offer if their first wager wins. Both offers require the code SIBONUS50 at registration and a minimum $10 deposit.
For the $1,500 First Bet offer, here is how the bonus bets break down based on your wager amount:
- If you wager $50 or less and lose, you receive one bonus bet equal to your stake.
- If you wager more than $50 and lose, you receive five bonus bets, each worth 20% of your original wager.
- For example, a $1,500 losing bet on Cavaliers vs. Pistons Game 5 would return five $300 bonus bets, totaling $1,500.
- Bonus bets expire seven days after issuance.
- BetMGM does not return your stake when you use bonus bets to place a follow-up wager.
For users in MI, NJ, PA, and WV, the Bet $10, Get $150 offer works differently. Place a minimum $10 wager on any market -- say, the Colorado Avalanche to win Game 5 against the Minnesota Wild -- and if it wins, you receive $150 in bonus bets issued as three $50 bonus bets. Those bonus bets also expire seven days from issuance.
Win or lose on either offer, every new user who signs up with the BetMGM Sportsbook promo code SIBONUS50 also receives $50 in MGM Rewards Points. Those points are part of the BetMGM Rewards program, which lets you redeem points for bonus credits for digital play at BetMGM, MGM Rewards Points, Marriott Bonvoy Points, merchandise, and Gametime Vouchers. You can learn more about the full rewards program at the BetMGM Rewards page.
This BetMGM promotion is available to first-time users in the following states: AZ, CO, DC, IA, IL, IN, KS, KY, LA, MA, MD, MI, MS, NC, NJ, OH, PA, TN, VA, WV, WY. It is not available in NV, NY, or Ontario, Canada.

- Collect your bonus bets: If your first bet loses, BetMGM will credit your account with bonus bets within 24 hours. Use them within seven days before they expire.
- Withdraw winnings: Cash out real-money winnings at any time. Bonus bet payouts require you to use the bonus bet first -- the original bonus bet amount is not included in the payout.
