BetMGM Bonus Code Earns $1,100 First Bet Offer or $200 Bonus Bets for March Madness article feature image

BetMGM Mass. Duke-Oral Roberts, 03/16/2023

The real first round of the NCAA Tournament rolls on Friday, and three different BetMGM bonus codes can spice up the action for you.

All three offers are good for any game on any day throughout the weekend.

  • BetMGM bonus code TOPACTION1100 offers an $1,100 first bet on the house, meaning you’ll get refunded whatever you lost in bonus bets, should your first wager lose. This Action Network exclusive offer is available in all BetMGM states but MA, NY and Washington D.C.
  • TOPACTIONDANCE: Get $200 in bonus bets when you bet $10 on any college basketball moneyline. Available in all BetMGM states but New York and Washington D.C.
  • TOPACTION: For Massachusetts users only, get a $1,000 first bet on the house. Same offer as TOPACTION1100 above, but a slightly lower max.

Bonus bets are like a credit you’ll have to bet to turn into cash. Say you bet $20 in bonus bets on the ULL moneyline vs. Tennessee at +500. If ULL wins, you’d profit $100 ($20 x 5.0) but you wouldn’t keep the $20 bonus itself.

We’ll break down more about each offer below.

Using BetMGM Bonus Codes

New users can make their first bet with any sporting event at BetMGM. Here’s an example using the First Four game between Arizona State and Nevada.

The winner of this matchup advances to play TCU in the Round of 64. Our Patrick Strollo is siding with Arizona State on Wednesday night.

Arizona State snuck into the tournament, and now is the time to jump on it after opening as one-point favorites against Nevada. Looking to capitalize on the NCAA Tournament bid, I expect the Sun Devils to be ready for an impressive showing in Dayton.

Head coach Bobby Hurley has taken Arizona State to the Big Dance twice before and should be extremely prepared heading into the play-in game early this week.

The Sun Devils racked up five Quad 1 wins this season with a buzzer-beater over Arizona — one of the best finishes of the season — serving as a feather in their cap. Now, Arizona State will look to rely on its pesky defense to advance to the Round of 64.

Like Arizona State, Nevada is returning to the NCAA Tournament for the first time since 2019. The Wolf Pack have been extremely efficient this season, finishing fourth in the Mountain West in both scoring offense (72.6) and scoring defense (66.9).

Look for Arizona State’s defense to be the difference-maker in this game. The Sun Devils have been a shutdown defense inside the arc, ranking sixth in the nation in 2-point defense.

I like Arizona State at -1 and would play this all the way to -3.5.

BetMGM has Arizona State as a -2.5-point favorite at -110. Here is what happens if we deposit and bet $100 on Arizona State to cover.

  • If Arizona State covers the spread, you win $90.91 and keep your $100 wager.
  • If Arizona State doesn’t cover, you’ll earn $100 in bonus bets.

BetMGM Bonus Bets

The optimal betting strategy for bonus bets is wagering on a longshot or plus-money prop.

This is the best strategy because you only keep the winnings with a bonus bet. It’s much more profitable when you use a bonus bet on a prop with +300 odds or longer, as opposed to the -110 range.

Everyone is counting down to March Madness, but the Women’s NCAA Tournament also begins this week. South Carolina is the clear favorite, but there’s value with every other team.

Let’s say we take our $100 bonus bets and wager on Stanford at +900.

  • Stanford Wins the Women’s NCAA Tournament: You win $900 but don’t keep your $100 wager.
  • Stanford Loses the Women’s NCAA Tournament: You lose your $100 bonus bet.
