How Online Casino Bonuses Work in the USA

Online social casinos often offer bonuses to new players, commonly referred to as “welcome bonuses.” These are specifically designed to attract and reward newcomers when they sign up. Some of the most common types of bonuses include no-deposit bonuses, welcome bonuses, match bonuses, free spins, and loyalty rewards. Here’s a quick breakdown of the different types available:

  • No Deposit Bonus: This is also considered a “real money online casino no deposit bonus” in the USA. It allows you to start playing without depositing your own money, which is an excellent way for you to try new games.

  • Welcome Bonuses: Online casino sign-up bonuses usually match your initial deposit, giving you extra funds to play with right from the start.

  • Match Bonuses: Match bonuses, also referred to as “deposit bonuses,” enhance your deposits by a certain percentage, while casino free spins can be used on specific slot machines. The best deposit match bonuses allow you to explore different options without additional financial commitment.

  • Loyalty Programs and High Roller Rewards: These VIP loyalty programs help retain users by offering ongoing perks as you continue to engage with the casino.

  • Real Money Bonuses: If you’re playing at a “real money casino” or online sportsbook in one of the US states where this is legal, then you may be eligible for cashback or deposit bonuses. This is where you receive a specific percentage back with your payment or earn a percentage match on a credit card deposit. At sweepstakes or social casinos, you may be eligible to redeem your sweepstakes cash for dollars.

A lot of these bonuses are available country-wide, but you'll find that some USA online casinos may offer unique advantages for players in individual states. This is because some states have specific regulations applicable to their own jurisdictions.

Casino Bonuses in the USA: Wagering Requirements Explained

Whenever you see an online casino with a free signup bonus real money in the USA, it’s important to learn how wagering requirements work before you claim it. Wagering requirements refer to the amount of money you need to bet before you can withdraw any winnings generated from your bonus.

These rules are sometimes called a “playthrough” requirement because you need to “play through” the entire amount before you can cash out.

If you receive a $100 bonus with a 30x wagering requirement, you would need to wager a total of $3,000 (30 times $100) before cashing out your winnings.

Understanding this requirement gives you the opportunity to determine whether a bonus is actually worth claiming.

How To Clear Playthrough Requirements for Online Casino Bonuses in the US

To clear wagering requirements for online casino bonuses in the USA, you’ll want to follow these tips: 

  • Focus on casino games that contribute the most toward playthrough requirements. Generally, slots have a 100% contribution, while table games like blackjack and roulette may contribute significantly less or not at all.

  • Be sure to check the terms and conditions. Review each bonus for specifics on contributions.

  • Set a budget. Keep track of your wagers to prevent overspending while working toward clearing your bonus.

  • Beware of common bonus traps. You’ll come across casino promotions that seem too good to be true or have unrealistic wagering requirements, which only lead to frustration and loss.

  • Stay informed and strategic. You'll be better equipped to maximize your online casino experience while minimizing potential pitfalls.

When you decide to claim an offer from our list of online casino bonuses in the USA, you can guarantee that the playthrough requirements are realistic enough to pay out in the long term. At CasinoBonus.com, we only recommend promotions that are actually worth your time.

Are Online Casino Bonuses Legal in the US?

Licensing and regulation for online casino sites can differ greatly throughout the United States. It’s more complex than just outwardly saying online casino gambling is “legal” or “illegal.” This is because individual states are responsible for their own legislation.

On a federal level, there are laws stating that gambling and sports betting are prohibited. But it’s important to keep in mind that many of these laws were established before states had even put together their own constitutions. In fact, some laws regarding gambling were enacted prior to the invention of the Internet!

Thankfully, some US states have taken the reins and established their own regulations for online gambling. Here are the states with the most active regulations and their respective entities:

  • Connecticut – Gaming Policy Board

  • Delaware – Delaware Gaming Commission, Delaware Gaming Enforcement

  • Michigan – Michigan Gaming Control Board

  • Nevada – Nevada Gaming Control Board/Gaming Commission

  • New Jersey – New Jersey Division of Gaming Enforcement

  • Pennsylvania – Pennsylvania Gaming Control Board

  • Rhode Island – Rhode Island Division of Gaming and Athletics

  • West Virginia – West Virginia Gaming and Racing Association

While these jurisdictions have some laws established, there aren’t any that cover offshore casino sites. These websites are completely licensed and operate from international jurisdictions. Players in the United States are able to access them without restrictions.
