March Madness continues this Thursday, with four out of the eight Sweet 16 games taking place at T-Mobile Arena in Las Vegas and Madison Square Garden in New York. Caesars Massachusetts has odds on all of the upcoming college basketball, plus a welcome bonus for new users in the state for up to $1,500 in the form of first bet insurance. To claim the bonus, sign up using the Caesars Sportsbook MA promo code LSR1BET, and for more information, keep reading.

To unlock the bonus, enter the Caesars Sportsbook Massachusetts promo code LSR1BET when prompted. The current welcome bonus at Caesars Massachusetts is insurance on the first bet you place at the online sportsbook.

After you sign up, make your first bet, and if it loses, you’ll receive a refund equal to your original stake in the form of one bonus bet. The maximum bonus bet you can receive is $1,500, and if your first bet wins, you don’t receive a bonus, just the payout from your initial wager.

Note that you cannot withdraw the bonus bet without wagering it, nor can you divide the bonus bet into multiple smaller bets. The bonus bet will expire after 14 days if you don’t wager it. If the wager you place using the bonus bet wins, you don’t receive the amount of the wager back as part of the payout.

New users who sign up at Caesars Sportsbook will also receive 1,000 tier credits and 1,000 reward credits, which count toward the Caesars Rewards program. To create an account and claim the Caesars bonus, you must be located in Massachusetts and be 21 or older.
