The San Antonio Spurs take on the Miami Heat at 7:00 p.m. ET on Peacock this Monday, March 23, 2026, and BetMGM is offering added protection on your first wager. By signing up with the BetMGM bonus code TOPACTION, new users can receive up to $1,500 back in bonus bets if their initial bet doesn’t win.
This offer from the BetMGM bonus code TOPACTION is available in AZ, CO, DC, IA, IL, IN, LA, KS, KY, MA, MD, MI, NC, NJ, OH, PA, TN, VA, WV, WY, and NY. BetMGM also provides additional promotions for the NBA slate today, including the TOPTAN1500 code for a $1,500 deposit match and the ACTIONGET code for a $150 bet-and-get bonus.
BetMGM Bonus Code TOPACTION Overview for Spurs vs. Heat
The BetMGM bonus code TOPACTION provides a built-in safety net for your first bet on Spurs vs. Heat. If your initial wager loses, BetMGM can return up to $1,500 in bonus bets, helping reduce the risk when betting on a side, total, or player prop. To take full advantage, make sure your account is verified and funded before the 7:00 p.m. ET tip-off so you can place your bet without delays. If you don't want to bet on Spurs vs. Heat, you can look ahead to other NBA matchups or March Madness games.
It’s important to understand how bonus bets work. They are not withdrawable as cash—only the profit from a winning bonus bet is paid out. Because of this, bonus bets are best used on plus-money wagers or props where you can maximize potential returns without risking your own funds.
BetMGM Bonus Code TOPACTION: Bet on Spurs vs. Heat
Here’s an example of how the BetMGM bonus code TOPACTION works for Spurs vs. Heat. If you place a $1,500 bet on the San Antonio Spurs moneyline at -170, a winning bet would return $2,382.35 total, including $882.35 in profit.
If the bet loses, you would be down the initial $1,500 wager. However, because you used the BetMGM bonus code TOPACTION, BetMGM will issue $1,500 in bonus bets after settlement. These are typically distributed as five $300 bonus bets, which can be used on any available market.
Keep in mind that bonus bet stakes are not returned with winnings, so any payout reflects profit only. This makes it important to use them strategically to maximize value. Use your bonus bets or any other NBA games, or other events like March Madness college basketball games.
