How we rate & rank the casinos

Our goal is to provide you with objective, concise reviews of US online casinos, highlighting their key strengths and weaknesses.

This also means doing our due diligence on the casino's bonus and sign-up offers.

We use a set of essential criteria to evaluate each casino, ensuring effective comparison.

1. Game selection: We examine the variety and quality of games, from slots and table games to live dealer options, ensuring a broad gaming experience.

2. Bonuses & promotions: We review the generosity and fairness of casino sign-up bonuses, reload bonuses, no-deposit offers, and ongoing promotions, with a focus on transparent terms.

3. Mobile compatibility: We test the platform's mobile performance, including online casino app features, to ensure a seamless gaming experience on all devices.

4. Payment methods: We assess the range of deposit and withdrawal options, processing times, and any fees, prioritizing fast and secure transactions.

5. Security: We verify that the casino is licensed in the US and uses top-tier security measures like SSL encryption, so we only recommend safe casinos online.

6. Customer support: We evaluate the responsiveness and effectiveness of support options, including live chat, email, and phone.

7. Fair play: We review game fairness, focusing on return-to-player (RTP) rates and the integrity of random number generators.

We download each casino and interact with the platform ourselves, using our own money to test the quality.

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

This streamlined approach ensures you can make informed decisions based on what matters most in your online experience and choose the best bonus for you.

How do I choose the best casino bonuses online for me?

• Check legality and licensing: Ensure the casino is licensed and operates legally within your state. US online gambling laws vary by region, so verify that the casino is regulated by an authoritative body such as the New Jersey Division of Gaming Enforcement or the Pennsylvania Gaming Control Board.

• Understand the bonus terms and conditions: Always read the fine print associated with any casino bonus. Pay close attention to wagering requirements, expiration dates, and withdrawal limits, as these will determine how easy it is to convert your bonus into actual winnings.

• Evaluate wagering requirements: Wagering requirements indicate how many times you must play through a bonus before you can withdraw any winnings. Look for offers with lower requirements (e.g., 20x or 30x), as higher figures make it more difficult to cash out.

• Assess the types of online casino bonuses: Different casinos offer various types of promos such as online casino no deposit bonuses, match deposits, and free spins. Choose a bonus that aligns with your gaming preferences—if you prefer slot games, free spins may be more beneficial, while a match deposit is better for general play.

• Check bonus size and match percentage: While bigger bonuses might seem appealing, look at the match percentage. A 100% match on a $100 deposit might offer better value than a 50% match on $500, depending on your budget and how much you plan to deposit.

• Review game restrictions: Some bonuses are restricted to specific games, such as slots or table games. If you enjoy playing a variety of games, ensure the bonus isn’t limited to just one category.

• Consider withdrawal limits: Many bonuses impose withdrawal limits, capping how much you can cash out from bonus winnings. Lower withdrawal limits can drastically reduce the overall value of the offer, so look for casinos with higher or no limits.

• Check validity period: Bonus offers typically come with an expiration date, which can range from a few days to a month. Make sure you can meet the wagering requirements within the specified timeframe to avoid losing the bonus.

• Explore loyalty programs: Some casinos offer loyalty or VIP programs alongside their sign-up bonuses. If you plan to gamble regularly, look for casinos with rewarding loyalty schemes that offer ongoing perks such as cashback or additional bonuses.

• Look for fair and transparent reviews: Read reviews from reputable sources to gauge the overall user experience and trustworthiness of the casino. Look for casinos with a solid reputation for timely payouts and good customer support, as this indicates a more reliable platform.

How to gamble responsibly with bonuses on online casinos

Before we end this article, we need to caution you to always bet and play responsibly with casinos and their bonus offers.

To ensure you’re being cautious, these casino sites implement various responsible gambling practices that will help you keep your betting habits in check and prevent unhealthy behaviors.

• Limits: Online casinos 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 online casino. This prevents you from spending all of your winnings. There’s also the option for early cashout, so you can still get paid if the bet is starting to go sideways.

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

We created a 'how to bet on sports' guide that helps new sports bettors understand the industry better, to play safer and more responsibly.
