What Exactly Are Betting Bonuses?

Betting bonuses are promotional funds awarded to players, most commonly when they sign up with a new bookmaker. It’s important to understand that these are not withdrawable cash but are credits that must be used for placing wagers. The process to claim a sports betting offer usually involves finding a promotion you like, registering as a new player, fulfilling the specific qualifying requirements, and then receiving the bonus amount as stated in the welcome offer.

However, sportsbook bonus bets are not just for new customers. Existing players can also access promotions, sometimes on a weekly basis. Often, betting sites will offer bonuses if you wager a certain amount each week.

How to Choose the Perfect Betting Bonus

Choosing the best betting promotion depends on several factors, including your preferred offer type and staking amount. For players looking to deposit little to no money, no-deposit bonuses or “bet and get” offers are ideal. These promotions provide a bonus after a small initial wager or sometimes for just signing up.

Conversely, high rollers might find more value in cashback offers or substantial deposit matches, which reward larger initial deposits with a proportional bonus amount.

We recommend browsing the bonus offers at the top of this page. If you are a new player for a specific bookmaker, click our claim button, register your account, and meet the qualifying criteria to secure your welcome offer.

Common Questions About Sportsbook Bonuses

• Who is eligible to claim a sportsbook bonus?
  The offers on this page are typically exclusive to new players registering an account for the first time. If a promotion is available to existing users, it will be stated explicitly.
• Is a sportsbook promo code always required?
  Not always. The terms and conditions of the offer will specify if a promo code is needed to claim the bonus funds. If required, the code will be clearly provided.
• Can I use the same bonus code multiple times?
  This depends on the promotion. Most welcome offer codes are for one-time use only. However, some promotions for existing players may allow a code to be used on several occasions. Always check the T&Cs.

How Do Sportsbook Bonuses Function?

Once you’ve claimed your sports betting bonus, you can use it on various sporting events. Depending on the offer, your bonus funds may be restricted to a specific sport or bet type (like football accumulators), or they may be available for use on any sport.

To use your bonus, add your desired selection to the betslip and choose the option to pay with your bonus funds instead of your cash balance. A crucial point to remember is that when you win a bet placed with bonus funds, the original stake is not returned as part of your winnings, unlike a cash bet.

Your bonus funds will also have an expiration date, so be sure to use them before they become void.

The Different Kinds of Sportsbook Promotions

Sports betting offers come in many forms. Here are some of the most common types you will find with bookmakers:

• Welcome Offers: Exclusive promotions available only to customers signing up with a bookmaker for the first time.
• Deposit Bonus: This bonus requires an initial deposit to be unlocked. Often, it comes as a “deposit match,” where the bookmaker matches a percentage of your first deposit (e.g., a 100% match).
• No-Deposit Bonus Bets: Highly sought-after by players, a no-deposit bonus grants you betting credits without requiring you to fund your account first. These are quite rare.
• Bet and Get Bonus: The most common type of offer. You place a qualifying bet (e.g., “Bet $10”), and in return, you receive a set amount in bonus funds (e.g., “Get $30”).
• Betting App Bonuses: Some bookmakers offer enhanced promotions exclusively for players who sign up or bet through their mobile app.
• Cashback Bonus: This offer refunds a percentage of your net losses over a specific period, either as bonus funds or real cash.
• Crypto Betting Bonuses: Specific sign-up offers for crypto betting sites, which can sometimes be more lucrative than traditional currency bonuses.

Important Terms and Conditions to Consider

Before claiming any betting bonus, it is essential to read the terms and conditions. Key factors to look for include:
