How we rate & rank US sportsbook promotions

Our team aims to provide you with unbiased, objective promo reviews, so you understand their strengths and weaknesses.

We always use a set of eight criteria to evaluate each promo offer, which means you can compare them easily and effectively:

1. Type of promo: We prioritize promotions that appeal broadly, enhancing user engagement with bet deals suited to different betting styles.

2. Promo value: We assess the value for money, ensuring bettors receive substantial rewards and maximum returns from participating in sports betting promotions.

3. Customer support: We test the effectiveness of customer support, focusing on resolving promo-related issues quickly and building user trust.

4. Promo expiry date: We evaluate the timeframe allowed for using promos, ensuring bettors have ample time to make the most of their bonuses.

5. Wager T&Cs: We review wagering terms and conditions to ensure they are fair and transparent, allowing bettors to fully enjoy their rewards.

6. Sportsbook experience: We assess the overall online sportsbook experience, ensuring users can easily navigate and claim promotions across both web and sports betting app platforms.

7. Minimum bet deposit: We verify the accessibility of betting promos by checking for low minimum bet deposits, making them available to more bettors.

8. Sports betting site security: We ensure top-tier security measures are in place, protecting bettors’ data and finances when engaging with promotions.

We download each US sports betting site and interact with the promo offers, using our own money to test the quality.

If we do not recommend the promo to our friends and family, we will not recommend it to you!

Choosing the best sportsbook bonus bets

• Review the wagering requirements: When choosing a sportsbook sign up bonus bet, carefully review the wagering requirements, which determine how many times you must bet the bonus amount before you can withdraw any winnings. Look for betting welcome bonuses with reasonable requirements—ideally, lower playthrough requirements that offer a better chance to cash out your earnings without excessive betting.

• Check the expiration date: Always check the expiration date of the betting bonus to ensure you have enough time to meet the terms and conditions. Some bonus bets may only be valid for a short period, such as 7 or 14 days, so make sure the time frame fits your betting schedule and allows you to comfortably fulfil the requirements.

• Assess the flexibility of use: Look for sportsbook bonuses that allow you to use the promotion across a wide variety of sports and bet types, such as single bets, accumulators, or in-play betting. Bonuses with flexible terms enable you to take advantage of your preferred sports and strategies without being confined to specific conditions or restrictions.

• Consider the initial deposit requirement: Pay attention to the minimum deposit required to activate the bonus, ensuring it aligns with your budget and betting strategy. Some sportsbooks may require a larger deposit to unlock bigger bonuses, so make sure the amount fits comfortably within your financial plan without overextending yourself.

• Look for additional perks: Bonuses that come with extra perks, such as boosted odds, online bets, or bets, can enhance the overall value of the promotion. These additional benefits increase your chances of making profitable wagers and getting more out of the bonus beyond just the initial offer.

How to bet responsibly with US betting promos

Although knowing your sports helps, betting is primarily luck-based, so use these top tips to practice responsible gambling when placing a bet:

• Limits: Legal betting sites allow you to set betting limits, i.e. limit how much you can bet in a day, a week, or a month.

• Cashouts: You can withdraw your winnings quite easily from any secure bookmaker, which prevents you from spending all of your winnings.

• Help & Resources: Regulated sportsbooks provide access to resources for problem gamblers and point them to organizations that can help with gambling addiction.

To help with gambling, we created a 'how to bet on sports' guide, that helps new sports bettors understand the industry better, to play safer and more securely.
