Types of Sportsbook Promos & Current Offers for Today, September 25, 2023
Bonus Bet Promos
A bonus bet offers a chance to win without using your own money. Bonus bets are a type of sportsbook promo given up front when you make a deposit or part of a first-bet refund. Bonus bets are typically fixed-value wagers, meaning a $25 bonus bet would mean placing the full amount on a wager of the bettor’s choice. However, some sportsbooks allow bettors to split their bonus bets into multiple wagers of different value.

Sports Betting Promo | Details | Claim Link |
---|---|---|
MLB SGP Weekly Bet & Get | Bet three $10+ MLB SGPs over the course of the week for a $10 bonus bet. | Claim at BetRivers |
Parlay Party | Place 4+ leg parlays four or more days each week to earn bonus bets. | Claim at BetRivers |
Dinger Tuesdays | Place a pre-live, straight, $25+ "To Hit a Home Run" Wager on select Tuesday MLB games and get a $5 bonus in bonus bets for each HR hit by both teams in the game. Up to $25. | Claim at FanDuel |
To use a bonus bet, select the wager, then choose the bonus bet option rather than using your own money.
Note that bonus bets pay winnings only, meaning the value of the bonus bet is not included in the payout. For example, if you placed a $25 wager with your own money on +100 odds and win, you’d receive $50 ($25 wager + $25 winnings). But if you placed a $25 bonus bet on +100 odds and win, you’d receive $25 in real money which you can cash out or continue playing with.
Second-Chance Bet Promos
A second-chance sports betting bonus, also known as first bet insurance, gives bettors the opportunity to wager a second time if their first bet loses. For example, if you sign up at a sportsbook and place your first bet of $100 and it loses, you’ll receive $100 back in bonus bets.

Tennis Parlay Insurance | Place a 4+ leg tennis parlay, get a bonus bet if your bet loses. | Claim at BetRivers |
Depending on the sportsbook’s terms and conditions, the refunded wager could be a single bonus bet of equal value, multiple fixed-value bonus bets, or betting credits you can use in any combination.
Keep in mind that bet insurance is not a “risk-free wager,” because you still have to wager the refunded bet to cash out.
Odds Boosts Promos
Odds boosts are among the most common ongoing sports betting promotions you’ll find. These may be automatically applied, or you may have to opt-in to them.

Essentially, an odds boost does exactly what it says. It boosts the odds on a certain bet, increasing your potential return. Let’s say a bet was originally +100 odds, and an odds boost brought it to +140 odds. That means that if you wagered $100 and won the bet, you would have originally won $100 for a total payout of $200. With the odds boost, you would win $140 for a total payout of $240.
Deposit-Match Bonuses
A deposit-match bonus gives bettors bonus money based on the size of their first deposit, which means most deposit-match bonuses are reserved for new signups.
Sports Betting Promo | Details | Claim Link |
---|---|---|
20% deposit-match bonus up to $1,000 | New members only. Make a deposit between $5 and $5,000. DraftKings will credit $1 in bonus money for every $25 wagered. | Claim at DraftKings |
For example, a 100% deposit-match bonus means the sportsbook will give you bonus money equal to your first deposit. If you deposit $100, you’d have $100 in your money and $100 in bonus money. If the deposit-match is 20% and you deposit $1,000, you’d have $1,000 in your own money and $200 in bonus money.
Keep in mind that deposit-match promos have a maximum value, usually between $250 and $1,000, and the percentage of the match can vary. The terms and conditions of the sportsbook bonus will also specify whether you receive the bonus money up front after your deposit, or if you earn bonus money as you place wagers. Either way, the deposit-match bonus only applies to your first wager, so keep that in mind when claiming.
How To Claim a Sportsbook Sign Up Bonus

- Before completing registration, make sure to claim your sportsbook promotion. The sportsbook promo code should automatically fill in for you. But if it hasn’t, head back here to copy the promo code, then paste it into the designated field.
- Once you’ve registered and been verified, it’s time to complete the tasks required to claim your chosen sportsbook sign up bonus, such as make a deposit or place a first bet. Refer back to the information that you read earlier in the process for details.

Understanding Sportsbook Bonus Terms & Conditions
By this point, you’ve most likely noticed that we’ve been repeatedly harping on reading the terms and conditions before jumping into any sportsbook promo. You may be asking yourself what you should be looking for within those terms and conditions, but ask no more. Here are the most important sportsbook bonus terms & conditions:
Wagering Requirements
Wagering requirements, also sometimes referred to as playthrough requirements, dictate how many times you must play through bonus funds or a bonus bet before it’s converted to withdrawable cash. For example, a $100 bonus with 1x playthrough would be converted to cash after $100 is wagered. That same $100 bonus with a 5x playthrough would be converted to cash after $500 is wagered. Generally, the lower the wagering requirements, the better.
Minimum Odds
Next up for consideration is minimum odds. Certainly, it would be easy to clear a bonus into withdrawable cash if you were allowed to place it on -500 odds. That’s why most bonuses come with minimum odds, meaning you must use that bonus on odds of at least a certain number. This also applies to earning bonuses. For example, say that you can place a specific bet in order to earn a bonus bet. You’ll most likely find that there are minimum odds for the bet you place to qualify.
Minimum Bet Size
For the most part, this section of the terms and conditions is self-explanatory. The terms may dictate a minimum bet size in order to qualify, so make sure to keep an eye out and ensure that this minimum bet size fits within your budget and allows you to play comfortably.
Maximum Win
Sometimes, the wins from a bonus may be capped at a certain amount. This is worth discovering in the terms and conditions because it may make a bonus not particularly worth it for you.
Combining With Other Promos
Terms and conditions will often specify whether or not a bonus can be combined with other promotions. Keep an eye out for this, as it may dictate whether or not you’d still like to claim a particular promotion or bonus.
Time Limit
Time limit, as mentioned earlier, is an important piece of the puzzle for sportsbook promos. Almost all bonuses will expire after a certain amount of time, and that time could be anywhere from one day to 30 days or more. Make sure that the bonus you’re looking to claim fits your timeline and doesn’t push you to wager uncomfortably just to clear it.

Sportsbook Promo Expert Tips
1. Only Bet What You’re Ready to Lose
No matter how sportsbook promos are framed or what they say, promotions are never risk-free. Even with second-chance bets, which are often misconstrued to create a risk-free opportunity, your bonus bets are getting paid back in bonus funds that require clearing before they become withdrawable. There is always an inherent risk in gambling your own money, so never bet above your means or more than you’re willing to lose.
2. Follow All Terms & Conditions
Don’t blow your bonus opportunity by missing a section of the terms and conditions. Make sure to follow the stipulations so that you don’t find yourself ineligible after spending money in order to attempt to claim a sportsbook promo. This includes reading up on time restrictions, minimum odds, and eligible wagers, amongst other things.
3. Consider Claiming Multiple Sportsbook Bonuses
In reality, as long as you’re comfortable you can claim as many sportsbook bonuses as you’d like. Hopping around and taking advantage of various sportsbook promo codes for new players and other sportsbook promos for existing users could serve to maximize value on your wagers. Always look for the best current promotions and the best odds to ensure you’re betting in the right place at the right time.
4. Promotions Can Be Seasonal
Some promotions are only available during certain seasons or certain major events such as the Super Bowl. This is the nature of sports and sports betting, so make sure if you want to take advantage of any of these bonuses that you’re jumping in when you can and watching for time limits, expiration dates, and anything else that could affect your eligibility. After all, nobody wants to spot generous Super Bowl promotions just to hop on the next day to regular, less generous promotions.
5. Refer-a-Friend to Bonus.com
Almost every sportsbook will offer a refer-a-friend program. That’s nice to have, but hear us out — refer your friends to Bonus.com instead. Our exclusive sportsbook promo codes almost always offer your friend a bigger welcome bonus, and they may still be able to enter your name as a referral upon registration. After all, you do want your friend to get the best bang for their buck, right?
Sports Betting Promos By State
Online sports betting is rapidly expanding across the US, already overtaking more than half the states and the nation’s capital. However, the two biggest states by population—California and Texas—have not legalized sports betting, and Florida continues struggling to launch an online sports betting market. So while this list of online sports betting promos by state will continue to expand (and we’ll update accordingly), these are the bonuses going on right now as of September 2023.
