Caesars Massachusetts Promo Code Delivers $1.5K First Bet for March Madness

Caesars entered Massachusetts on Friday with a bang. Every first-time Massachusetts player that uses the code MHSXL1BET to register will earn a first bet on Caesars worth as much as $1,500. For perspective, no sportsbook currently lets new Massachusetts customers bet so much while promising a complete bonus bet refund.

Following a brief registration, place an eligible cash wager on any game worth up to $1,500. Caesars will cover losses with a fully-refunded bonus bet that serves as a well-deserved second chance. If you win, you’ll score a sizable cash payout and a healthy bankroll heading into the tournament.

Caesars Massachusetts Promo Code Instructions

Before the First Four and the rest of the NCAA Tournament tip off, here’s how prospective players can take advantage of Massachusetts’ launch week offer and place a first bet on the house worth up to $1,500:

  • Click here to trigger our Caesars Massachusetts promo code MHSXL1BET.
  • Complete each necessary registration field.
  • Confirm you’re within Massachusetts state lines with a geolocation check.
  • Make a cash deposit using one of Caesars’ approved banking methods.
  • Place up to $1,500 on any eligible betting market, including the NCAA Tournament.
  • Earn a fully-refunded bonus bet (max. $1,500) after a loss. A win cancels the bonus bet refund and pays out every dollar of expected cash profit.

Play-In Parlay Boost

Although many consider the Round of 64 as the start of the madness, Caesars has a First Four parlay that offers a substantial cash payout if it hits. Bet up to $100 on Caesars’ “Play-In Parlay Boost,” which puts +1000 odds on Texas A&M-CC, Pittsburgh, Texas Southern, and Arizona State winning. Pittsburgh (+118) is the only betting underdog of the four highlighted teams, with a win promising up to $1,000 in cold, hard cash.

Caesars also allows players to boost any college basketball market during the First Four. Opt into the “Profits for the People” promo to claim your 44% profit token. This gives bettors the freedom to boost any market, not just a moneyline parlay.
