Caesars Sportsbook Promo Code for March Madness Round 1: Bet $1, Get 10 Profit Boosts

New users can claim an exciting welcome offer with the Caesars Sportsbook promo code SICZRDYW ahead of March Madness Round 1. This Wednesday, March 18 promotion allows eligible bettors to bet $1 and receive 10 100% profit boost tokens for wagering on Thursday's tournament action. March Madness begins with exciting matchups from TCU vs. Ohio State through Idaho vs. Houston, and new Caesars users can explore various sportsbook promos for the tournament.
How the Caesars Sportsbook promo code works for March Madness betting
The Caesars Sportsbook promo code SICZRDYW provides new users with 10 100% profit boost tokens after placing their first qualifying wager of at least $1. Each boost token can be applied to wagers up to $25, effectively doubling your potential winnings on successful bets. This offer gives bettors enhanced value when wagering on Thursday's March Madness Round 1 games.
The promotion requires users to place their first qualifying wager within 30 days of account creation. Several wager types do not qualify for this promotion:
• Wagers using existing profit boost tokens.
• Bets placed with reward credits or bonus funds.
• Super boosts or round robin wagers.
• Wagers with odds of -500 or shorter.
For example, if you bet $10 on Duke to cover the spread against Siena and win, your normal profit might be $9. With a 100% profit boost applied, you would receive $18 in profit instead. Conversely, if your boosted wager loses, you only lose your original stake without any additional penalties.
The profit boost tokens must be used on individual wagers and cannot be combined with other promotional offers. Each token expires according to Caesars Sportsbook's standard promotional terms, so users should plan to use them strategically across the tournament's early rounds.
This Caesars Sportsbook promotion is available to first-time users in the following states: AZ, CO, DC, IA, IL, IN, KS, KY, LA, MA, MD, ME, MI, MO, NC, NJ, NY, OH, PA, TN, VA, WV, WY. It is not available in NV, NY, or Ontario, Canada.
