March Madness Betting Promos for Final Four

Before getting started, let’s discuss some general details that apply to the best sportsbook promo codes for the Final Four. You’ll find two main offers among this collection of deals:

  • Bonus bets – You receive bonus wagers after betting a specified amount (e.g., $10). For a winning bonus bet, you’ll get the winnings minus the stake (e.g., bet $50, win $45 = collect $45).
  • First-bet insurance – You place your first wager and wait for it to settle. Assuming you lose, you’ll get a matching refund in bonus bets.


Bonus bet winnings are subject to wagering requirements (a.k.a. rollover) before they become cashable. All of the betting sites covered here require 1x rollover, which is the lowest possible.



BetMGM March Matchups Betting Promo for the Final 4 Matchups

BetMGM is offering a “March Matchups” Bet $10, Get $200 deal. As this implies, you only need to place a $10 minimum first bet to collect $200 in bonus bets. March Matchups will run from now until April 3, 2023 (Championship Game).

You need to use the promo code GAMBLINGMARCH when registering to qualify. You’ll also have to make a first-time deposit of at least $10 at the BetMGM Sportsbook. The final step is to make your first wager worth $10 or more.

Bet365 March Madness Promo for Final Four

The Bet365 March Madness bonus code GAMBLING qualifies you for a Bet $1, Get $200 offer. In other words, you merely have to wager $1 to receive $200 in bonus bets. We see GAMBLING as the best March Madness bonus code available due to its $1 minimum wager and large bonus.

This deal requires a $10 minimum deposit in addition to the GAMBLING promo code. Afterward, you just need to place your first bet of $1 or more to get $200 in bonus wagers. You have until the Championship Game (4/3/23) to claim this Bet365 Sportsbook offer.

DraftKings March Madness Betting Promo Final 4

DraftKings Sportsbook is currently offering a Bet $5, Get $150 deal. The name says it all: you place a $5 minimum wager and collect $150 in bonus bets. No March Madness promo code is necessary to qualify for this offer. 

You will, however, need to visit the Sportsbook through our banner below. Additionally, you’ll have to place DraftKings’ minimum deposit of $5 or more. The final step involves betting at least $5 on a college basketball game. You’ll then receive six individual $25 bonus bets ($150 total).

Betway March Madness Betting Promo

The Betway Final Four bonus differs from all other promos on this page. It provides first-best insurance worth up to $250 on your first wager (-300 minimum odds). If your first loses, you collect the matching value in bonus bets up to $250.

Betway Sportsbook doesn’t require a March Madness bonus code during registration, but you must visit through our banner below. Additionally, you’ll need to deposit at least $10 and opt-in to the promotion. After placing your first bet at -300 odds or greater (e.g., -250), you wait to see if it wins/loses.

WynnBET March Madness Betting Promo

The WynnBET Sportsbook currently has a Bet $100, Get $100 Final Four offer. No March Madness bonus codes are necessary for this offer—just visit through our link in the banner.

Once at WynnBET, you’ll need to register and deposit $100 or more. You then must place a $100 minimum bet at -120 minimum odds, or greater, to get $100 in bonus bets. The WynnBET bonus isn’t quite as desirable as other promos on this list, but it’s still worth considering.

How to Claim March Madness Betting Promos

March Madness bonuses can have slightly different qualification steps from each other. However, you’ll typically go through the same general process when claiming these bonuses. Here are the common steps.


  1. Visit the relevant online sportsbook (you may need to use our link for qualification).
  2. Sign up and use the proper March Madness bonus code (if required).
  3. Make the minimum deposit (e.g., $10).
  4. Place the minimum wager (e.g., $5).


Each college basketball bonus comes with terms and conditions, which vary slightly from one offer to the next. For example, you might need to place your first bet at minimum odds (e.g., -200). We recommend that you always read the terms behind promo codes before using them.
