WynnBet Mass Boston-Celtics, 03/11/2023

Friday has come and gone, meaning online sports betting is officially live in Massachusetts. The WynnBET promo code XTANMASS gives users in Massachusetts $100 in bonus bets following their first bet of $100.

MA residents can use this link to signup for WynnBET or use XTANMASS at checkout to access the promo.

WynnBet offers a more limited betting menu than most sportsbooks but has strong pricing on moneylines in particular.

If you want to join WynnBET from another state, use the promo code XACTION for a “bet $20, get $100 in bonus bets” offer in AZ, CO, IN, LA, TN and VA. In NJ and Michigan, use XACTIONBET for a $50 sportsbook credit and $50 casino credit.

Using Bonus Bets at WynnBET

We recommend using a bonus bet on a plus-money prop or longshot. This is because you only keep the winnings when wagering with bonus bets.

A certain basketball team in Massachusetts presents strong value for the NBA Finals. Here is a breakdown of betting $50 in bonus bets on the Celtics at +330.

  • If the Celtics win the NBA Finals, you win $165 but not your $50 wager.
  • If the Celtics don’t win the championship, you lose your $50 bonus bet.

How to Use Bonus Bets on Saturday

We always recommend using bonus bets on plus-money wagers due to the expected value. The math says the higher the line, the more EV, but because you don’t have an unlimited number of bonus bets, +300 to +500 is a good range.

Here are some of our staff’s favorite bets for Saturday.
