How the BetMGM bonus code works for weekend basketball and Winter Games betting
The BetMGM bonus code SI1500 provides two distinct welcome offers depending on your state.

Wagers over $50 split into five equal bonus bets, while smaller amounts receive one bonus bet. If you win your NBA or Winter Games bet, you keep your winnings and can withdraw immediately.
Key terms include:
