Register now with the BetMGM bonus code ACTION1550 today to take advantage of a unique combo offer. Remember, this promo includes a first bet offer that yields back up to $1.5K in bonus bets if your first bet results in a loss. You also receive a $50 bonus upon completing the registration process.
Let's dive in and look at a betting example from Thunder vs. Suns to demonstrate how this welcome bonus works.
Suppose I place a $1K first bet on the Thunder -10.5 (-110) vs. the Suns:
- If the bet wins, I receive $909.09 in profit and my $1K stake back.
