How the BetMGM bonus code SI1500 offer works for Thursday's games
The BetMGM bonus code SI1500 delivers substantial value for new users ready to bet on Thursday's action-packed schedule. This BetMGM promo code requires the SI1500 code during registration and provides up to $1500 in bonus bets if your first real money wager loses.
Here's how the promotion breaks down:
• Make a minimum $10 deposit after using bonus code for BetMGM SI1500.
