DraftKings: Bet $5, Get $200 in Bonus Bets

How the DraftKings Bonus Works

DraftKings’ “Bet $5, Get $200” promotion is the most straightforward offer on the market. Here’s the mechanics:

1. Create a new DraftKings Sportsbook account
2. Deposit at least $5
3. Place your first bet of $5 or more on any market with odds of -300 or longer
4. Receive $200 in bonus bets instantly, regardless of whether your qualifying bet wins or loses
5. Bonus bets are issued as eight $25 bets that can be used on any market

What makes it great: The $200 is guaranteed — your qualifying bet doesn’t need to win. This means your only risk is the initial $5 wager. The 1x playthrough requirement means you only need to wager the bonus amount once before withdrawing any winnings. At an average +100 bet with a 50% win rate, the expected value of $200 in bonus bets is approximately $100.

Pro tip: Use the $200 in bonus bets on March Madness point spreads at -110, where the vig is lowest and your expected return is maximized. For more tips on maximizing your gambling bankroll, check our guide on the best gambling apps for real money.

BetMGM: Up to $1,500 in Bonus Bets (Code: COVERS)

How the BetMGM Bonus Works

BetMGM offers the largest single-bet bonus in the industry. The mechanics:

1. Create a new account and enter promo code COVERS during registration
2. Deposit at least $10 (but you’ll want to deposit more to maximize the bonus)
3. Place your first bet on any market — up to $1,500
4. If your first bet wins: you keep your winnings normally (no bonus needed)
5. If your first bet loses: BetMGM credits you with bonus bets equal to your wager amount, up to $1,500
6. Bonus bets are issued as five equal installments (e.g., 5x $300 for a $1,500 qualifying bet)

Strategic approach: Since the bonus only activates if your first bet loses, consider placing your qualifying bet on a slight underdog (+110 to +150). If it wins, you profit from the underdog payout. If it loses, you get the full $1,500 back in bonus bets. Either outcome is positive expected value.

Important note: BetMGM bonus bets do NOT return the stake — only the winnings. A $300 bonus bet at +100 that wins returns $300 in profit, not $600. Factor this into your expected value calculations.

Caesars: 10x 100% Profit Boosts

How Caesars Profit Boosts Work

Caesars takes a different approach from traditional first-bet bonuses. Instead of protecting a losing bet, they double your winnings on your next 10 bets:

1. Sign up and enter promo code SPORTSLINEDYW
2. Deposit at least $20
3. Place any bet of $1+ at -500 or longer odds
4. Receive 10 profit boost tokens
5. Each token doubles your winnings on a bet up to $25 stake

Value calculation: If you use all 10 tokens on $25 bets at even money (+100), your expected additional profit is approximately $125 (10 bets x $25 x 50% win rate x 100% boost = $125). The total maximum additional winnings is $2,500 per token, which activates on longshot bets at high odds.

Optimal strategy: Use the profit boosts on parlays or longshot bets where the boost has the highest absolute value. A $25 bet at +500 returns $125 in profit normally, or $250 with the 100% boost — an extra $125. On a -110 bet, the extra profit is only about $11.36. Longshots maximize the boost’s dollar value.

FanDuel: Up to $3,000 in No Sweat Tokens

How FanDuel’s Promotion Works

FanDuel’s promotion is the most valuable but requires the most engagement:

1. Create a new FanDuel account (no code needed)
2. Each day for 10 consecutive days, place a qualifying bet
3. If that day’s bet loses, receive a “No Sweat Token” worth up to $300
4. If it wins, you keep the winnings but don’t receive a token
5. Maximum total value: $3,000 (10 days x $300)

Realistic value: Since tokens only activate on losses, you won’t receive all $3,000. Assuming a 50% win rate on daily qualifying bets, you’d receive approximately 5 tokens worth $1,500 total. With 1x playthrough and a 50% conversion rate, the expected real value is approximately $750.

Strategic tip: Place your qualifying bets on heavy favorites (-300 or so). You’ll win most of them outright, and on the occasional loss, you’ll receive a large No Sweat Token. This approach reduces variance while still accumulating bonus value. March Madness first-round games with heavy favorites are perfect for this strategy.

Fanatics: Bet $5, Get $200 in FanCash

What Makes Fanatics Different

Fanatics’ unique angle is the FanCash system, which can be used for both sports betting AND merchandise on Fanatics.com:

• $200 FanCash can be used as $200 in bonus bets on the sportsbook
• Alternatively, use it for $200 worth of jerseys, hats, and gear on Fanatics.com
• In select states, the promotion scales up to $1,000 in FanCash
• FanCash earned from winning bets can also be used on merchandise

Best for: Sports fans who want flexibility between betting and merch. If you’re not confident in converting bonus bets into cash, the merchandise option guarantees you get full retail value.

Hard Rock Bet: 10x 100% Profit Boosts

How Hard Rock Bet Compares to Caesars

Hard Rock Bet’s profit boost promotion is similar to Caesars’ but with key differences:

• Higher max stake: $50 per boost (vs. Caesars’ $25)
• Longer expiry: 30 days (vs. Caesars’ 14 days)
• No promo code needed: Automatically applied at sign-up
• Limited state availability: Currently available in fewer states than Caesars

With $50 max stakes and 100% boosts on 10 bets, the expected additional value at even-money odds is approximately $250 — double the Caesars offer. The 30-day expiry gives you more time to find optimal spots, which is particularly valuable during March Madness when you can spread boosts across three weekends of tournament action.

ESPN BET: First Bet Reset Up to $1,000

How ESPN BET Works

ESPN BET’s “First Bet Reset” functions similarly to BetMGM’s first-bet protection but with a lower ceiling:

1. Create an account with code ESPNBET
2. Place your first bet up to $1,000
3. If it loses, receive the wager amount back as bonus bets
4. Use bonus bets within 7 days

Integration advantage: ESPN BET is directly integrated into the ESPN app and website. If you already use ESPN for scores, news, and fantasy sports, the seamless integration makes placing bets frictionless. The app surfaces relevant betting odds directly within game pages and articles.

bet365: $365 Bonus Bets or $1,000 Safety Net

Which bet365 Offer Should You Choose?

bet365 is unique in offering a choice between two fundamentally different promotions:

Option A: $365 Bonus Bets (Best for small bankroll management)

• Bet just $10 on any market
• Win or lose, receive $365 in bonus bets
• Guaranteed value — no luck required
• Expected real value: approximately $180 after 1x playthrough

Option B: $1,000 Safety Net (Best for large bankrolls)

• Place your first bet up to $1,000
• If it loses, get the amount back as bonus bets
• Higher ceiling but requires risking more upfront
• Expected real value: approximately $250 (factoring in the probability of needing the safety net)

Our recommendation: If your bankroll is under $500, take Option A — the guaranteed $365 is better expected value for smaller stakes. If your bankroll is $1,000+, Option B provides higher potential return. For deeper analysis on bankroll strategies, see our zero-risk betting strategy article.

Wagering Requirements Explained

Understanding wagering requirements is critical for extracting real value from sportsbook bonuses:

What “1x Playthrough” Means

A 1x playthrough (also called 1x rollover) means you must wager the bonus amount once before you can withdraw any winnings. For example:

• You receive $200 in bonus bets
• You must place $200 worth of bets using those bonus bets
• Any winnings from those bets can be withdrawn immediately
• The bonus bet stake is NOT returned — only the profit

Bonus Bets vs. Free Bets vs. Cash Bonuses

• Bonus bets (most common): Winnings are returned as real cash, but the original bonus bet stake is not. A $100 bonus bet at +100 that wins returns $100 profit (not $200).
• Free bets: Functionally identical to bonus bets in most cases.
• Cash bonuses: Rare in sports betting. Both the stake and winnings are real money, but often come with higher playthrough requirements (5x-10x).

Expected Value of Bonus Bets

At 1x playthrough with standard -110 odds, a $100 bonus bet has an expected value of approximately $45.45. Here’s the math: 50% chance of winning $90.91 = $45.45 expected value. This means DraftKings’ $200 in bonus bets is worth approximately $91 in real money casinos.

Step-by-Step Redemption Guide

Common Redemption Mistakes to Avoid

• Forgetting the promo code: BetMGM and Caesars require a promo code at signup. If you skip this step, you may not receive the bonus and cannot add it retroactively.
• Not meeting minimum odds: Some promotions require your qualifying bet to be at -300 or longer. A bet at -400 would NOT qualify.
• Letting bonus bets expire: Most bonus bets expire within 7 days. Set a phone reminder to use them before they vanish.
• Not opting in: Some promotions require you to click an “Opt In” button in the promotions tab of the app. Check this before placing your qualifying bet.

Bonus Stacking Strategy

The best approach in March 2026 is to sign up for multiple sportsbooks and claim all available bonuses. Here’s the optimal stacking strategy:

Week 1: High-Value First Bet Protections

1. BetMGM ($1,500): Place your largest first bet here — maximum protection
2. ESPN BET ($1,000): Second-largest first bet
3. bet365 ($1,000 safety net): Third-largest first bet

Week 2: Guaranteed Bonus Bets

1. DraftKings ($200): Risk just $5, get $200 guaranteed
2. Fanatics ($200): Another $5 bet for $200 guaranteed

Week 3: Profit Boosts for March Madness

1. Caesars (10 boosts): Use on Sweet 16 and Elite 8 games
2. Hard Rock Bet (10 boosts): Save for Final Four weekend for maximum impact

Ongoing: FanDuel Daily Promotion

1. FanDuel (10 days, up to $3,000): Place one qualifying bet per day during March Madness

Total potential value across all 8 sportsbooks: $8,865+

Key Terms and Conditions

Every promotion comes with terms. Here are the most important ones across all sportsbooks:

• New customers only: Every bonus listed is for first-time account holders. You cannot create a second account to claim a bonus again.
• Age requirement: Must be 21+ in all states except Wyoming (18+).
• Location requirement: Must be physically located in an eligible state. Your account registration state doesn’t matter — your physical location at the time of betting does.
• Bonus bets cannot be withdrawn: Only the WINNINGS from bonus bets can be withdrawn. The bonus bet stake is consumed when placed.
• One account per person: Creating multiple accounts to abuse promotions is a violation of terms and will result in account closure and forfeiture of all funds.

Best March Madness Promos

Several sportsbooks are running March Madness-specific promotions in addition to their standard welcome offers:

• DraftKings: Daily odds boosts on March Madness games — check the “Promos” tab each morning for enhanced lines on featured matchups
• FanDuel: “March Madness parlay bets Insurance” — if one leg of a 4+ leg March Madness parlay loses, receive a bonus bet back up to $25
• BetMGM: “One Game Parlay Bonus” — place a 3+ leg SGP on any tournament game, get a $5 bonus bet win or lose
• Caesars: “Sweet 16 Super Boost” — enhanced odds on select Sweet 16 games, changing daily

These March Madness-specific promos stack on top of the welcome bonuses, providing additional value for new customers who sign up during the tournament. Explore our AI sports predictions for data-driven March Madness picks to use with these bonuses.

Responsible Gambling

• Set deposit limits before claiming any bonus. Every legal sportsbook allows you to set daily, weekly, and monthly deposit caps.
• Don’t deposit more than you can afford just to maximize a bonus. BetMGM’s $1,500 first bet protection doesn’t mean you should deposit $1,500 if that’s outside your comfort zone.
• Use cooling-off periods if you find yourself chasing losses. Every sportsbook offers temporary self-exclusion options.
• Remember the math: Even with optimal bonus conversion, the house has a long-term edge. Bonuses reduce that edge temporarily, but they don’t eliminate it.
• Never borrow money to gamble, even with generous bonuses available.
