The NCAA didn't hold back on its first day matchups for Round 1 of the 2023 men's basketball tournament, as five of the six tourney favorites are playing that day, including three of the four No. 1 seeds (Kansas, Alabama and Houston). Sports bettors won't have to hold back on their first wager on that day, either, if they sign up for the Caesars Sportsbook promo code SBWIREFULL that has a first-bet offer up to $1,250.
Lose your initial bet on any Round 1 March Madness matchup after becoming a customer with the Caesars Sportsbook promo code SBWIREFULL and the first-bet offer will refund your loss with a bet credit up to $1,250.
The Caesars Sportsbook promo code SBWIREFULL has even more than this, as it furnishes your new Caesars Rewards account with 1,000 Tier Credits and 1,000 Rewards Credits whether your first bet wins or loses.
