March Madness will finally conclude on Monday night with the Purdue Boilermakers taking on the UConn Huskies. The two one-seeds will battle it out at 9:20 p.m. ET. You can claim multiple online sports betting promos when you sign up at some of the top online sportsbooks ahead of the game.

These promos come in various forms, including Bet & Get promos, first bet insurance, and deposit matches. Each offer has varying levels of value, so we'll explain which ones offer the most.

Let's discuss some of the nine most lucrative online sports betting promos to claim for the NCAA Championship, Purdue vs. UConn.

Online Sports Betting Promos: NCAA Championship

BetMGM: 20% Match

• Bonus Code: TOPTAN1600
• Offer: Get a 20% Deposit Match up to $1,600 in Sports Bonus
• Available States: AZ, CO, IL, IN, IA, LA, KS, KY, MA, MD, MI, NJ, OH, PA, TN, VA, WV, WY

Using the BetMGM bonus codeTOPTAN1600, you can claim a 20% deposit match of up to $1.6K in bonus bets. This promo has a 10x rollover, meaning that for every $1 in bonuses you're looking to claim, you must wager through $10 to unlock them.

For example, let's say you make your first deposit of $2K at BetMGM. Because of the 20% match, you would receive $400 in bonus bets. With the 10x rollover, you must bet through $4K to receive the bonus.

BetMGM: $1.5K First Bet

• Bonus Code: TOPACTION
• Offer: Get up to $1,500 Back in Bonus Bets if Your First Bet Doesn't Win
• Available States: AZ, CO, IL, IN, IA, LA, KS, KY, MA, MD, MI, NJ, OH, PA, TN, VA, WV, WY

Instead of TOPTAN1600, you can use the BetMGM bonus code TOPACTION to get a $1.5K first-bet insurance promo. Place your first bet, and you receive the profit if it wins. If it loses, you are refunded your lost stake as bonus bets, up to $1.5K.

For example, I deposit and place a bet on Purdue +6.5 (-110) against UConn for $100. If my bet wins, I receive $90.91 in profit. If my bet loses, I am given back $100 in bonus bets.

ESPN BET: $225 Value

• Promo Code: ACTNEWS
• Offer: Make Any Sportsbook Bet, Get $150 in Bonus Bets – Guaranteed
• Available States: AZ, CO, IL, IN, IA, KS, KY, LA, MA, MD, MI, NJ, OH, PA, TN, VA, WV

ESPN BET delivers $225 in bonus bets when you place your first bet for any amount. Just use the ESPN BET promo codeACTNEWS to claim the offer.

Suppose I place my first bet for $5 on the Purdue moneyline (+235). If my bet wins, I receive $11.75 in profit and $225 in bonus bets. If my bet loses, I receive $225 in bonus bets only.

Caesars Sportsbook: $1K First Bet

• Promo Code: ACTION41000
• Offer: Get up to $1,000 Back in Bonus Bets if Your First Bet Doesn't Win
• Available States: AZ, CO, MA, IL, IN, IA, KS, KY, LA, MD, ME, MI, NJ, NY, OH, PA, TN, VA, WV, WY

Using the Caesars Sportsbook promo codeACTION41000, you can get a $1K first bet insurance promo. When you place your first bet, you'll get bonus bets refunded to you if you lose. If you win, you keep the profit.

For example, if you place a $1K first bet that loses, you receive a $1K bonus bet. This offer differs from other first-bet insurance promos because you can't spread your bonus across multiple wagers. So, in the above example, you must use your $1K bonus simultaneously.

FanDuel: Bet $5, Get $200

• Promo Code: None
• Offer: Bet $5, Get $200 in Bonus Bets if Your First Bet Wins
• Available States: AZ, CO, CT, IL, TN, IN, IA, KS, KY, LA, MA, MD, MI, NJ, NY, OH, PA, VA, VT, WV, WY

At FanDuel, you can place your first bet after registering for $5 or more and get $200 in bonus bets if it wins. This is different from most Bet & Get welcome bonuses, as this one doesn't guarantee your bonus bets. However, this promo has no minimum odds requirement, meaning you can bet on a hefty favorite without repercussions.

Betting on the UConn moneyline at -300 odds isn't a bad option. Just ensure you're putting yourself in the best possible position to earn the bonus because if you don't win your first bet, you won't get anything.

bet365: $1K First Bet or $150

• Bonus Code: TOPACTION
• Offer #1: Get a First Bet Safety Net up to $1,000 in Bonus Bets
• Offer #2: Bet $5+, Get $150 in Bonus Bets
• Available States: AZ, CO, IA, IN, KY, LA, NC, NJ, OH, VA

Using the bet365 bonus codeTOPACTION, you will get a choice between two welcome offers: a $1K first-bet safety net and a $150 Bet & Get. Both offers are quite simple, with the safety net as a standard first-bet insurance promo and the Bet & Get functioning as others. The same bonus code will get you either offer, but you can only claim one.

To qualify, you must make a minimum deposit of $10 and place your first bet at -500 odds or longer.

Fanatics Sportsbook: Up to $1K Bet Match

• Promo Code: None
• Offer: Bet and Get up to $1,000 in Bonus Bets
• Available States: AZ, CO, CT, IA, IL, IN, KS, KY, MD, MA, MI, NC, NY, OH, PA, TN, VT, VA, WV

All new Fanatics Sportsbook registrants can receive up to $1K in bonus bets across their first ten days on the site. Your first bet for ten consecutive days is matched up to $100. So, if you place your first bet for $50 each of the ten days, you'll get $500 in bonus bets. This offer is uniquely structured, but it can be pretty lucrative if you come close to maxing it out.

DraftKings: Bet $5, Get $150

• Promo Code: None
• Offer: Bet $5, Get $150 in Bonus Bets – Instantly
• Available States: AZ, CO, CT, IA, IL, IN, KS, KY, LA, MA, MD, ME, MI, NJ, NY, OH, PA, TN, VA, VT, WY, WV

When you sign up at DraftKings today, you can deposit and place your first bet for $5+ in exchange for $150 in bonus bets. This offer is available in most legal DK states. For example, suppose I place my first $5 bet on the Over 146.5 (+100) in Purdue vs. UConn. If the "over" hits, I win $5 in profit and $150 in bonus bets. If the "over" doesn't hit, I still receive the $150 bonus.
