Use BetMGM Massachusetts Bonus Code to Bet Knicks vs. Celtics Today
Let's look at how each BetMGM bonus code offer works when you sign up for a new account and bet on tonight's NBA matchup between the New York Knicks and Boston Celtics on ABC.
BetMGM Bonus Code ACTIONGET: Bet $5, Get $150 in Bonus Bets if You Win
Place a $5+ first bet and get back $150 in bonus bets if you win. Keep in mind that there is no minimum odds requirement attached to this offer with the BetMGM bonus code ACTIONGET. This means that placing your first bet at the shortest possible odds is optimal.
For example, let's say I place my first bet for $5 on the Celtics moneyline (-300):
- If the Celtics win, I get $1.67 in profit, my $5 stake back, and $150 in bonus bets.
- If the Celtics lose, I receive nothing.
BetMGM Bonus Code TOPTAN1500: $1,500 Deposit Match Offer
When you sign up with the BetMGM bonus code TOPTAN1500, you get a 20% deposit match of up to $1,500 in sports bonus. This offer has a 10x rollover requirement that you must meet within 30 days of claiming it.
For example, let's say I make an initial deposit of $2,000. The 20% match earns me $400 in sports bonus and I must wager through $4,000 within 30 days to meet the rollover and withdraw any winnings.
BetMGM Bonus Code TOPACTION: $1,500 First Bet Offer
Place a first bet, and if it loses, get back up to $1,500 in bonus bets to cover the loss with BetMGM bonus code TOPACTION. If you receive a bonus with this BetMGM promo, it is distributed in five equal increments that expire in seven days. Suppose I place my first bet for $200 on the Celtics to win both halves by 4+ points (+350):
- If the bet wins, I get $700 in profit and my $200 stake is credited back to my account.
- If the bet loses, I get $200 in bonus bets, distributed as five $40 bonus bets.
