BetMGM Bonus Code TOPACTION: Bet Tigers vs. Mariners ALDS Game 5
The BetMGM bonus code TOPACTION provides new users with a $1,500 first bet promo today. Place your first bet on Tigers vs. Mariners in ALDS Game 5 and get back up to $1,500 in bonus bets if you lose. Here is a betting example to demonstrate how the BetMGM promo works. Say I place a $1,000 first bet on the Mariners moneyline (+100) vs. Detroit:
- If the bet wins, I receive $1,000 in profit and my $1,000 stake back.
- If the bet loses, I receive five $200 bonus bets that expire after seven days.
BetMGM Bonus Code: Other Sign-Up Offers Available Today
There are two other BetMGM bonus code offers available to new users today. Instead of the first bet promo, claim either a bet-and-get offer or a 20% deposit match today. Let's take a look at how both of these sign-up offers function.
$150 Bet-and-Get
Place a $10+ first bet to get back $150 in bonus bets if you win. Register with the BetMGM bonus code ACTIONGET to secure this welcome bonus. For example, say I place a $10 initial wager on Tarik Skubal to record 5+ strikeouts (-3600):
- If the bet wins, I receive $0.28 in profit, my $10 stake back, and $150 in bonus bets.
- If the bet loses, I receive nothing.
20% Deposit Match
Sign up with the BetMGM bonus code TOPTAN1500 to get a 20% deposit match of up to $1,500 in sports bonus. This BetMGM promo has a 10x rollover requirement that must be met within 30 days to withdraw your winnings.
Suppose I make an initial deposit of $2,000. This provides $400 in sports bonus and I must wager through $4,000 within 30 days.
