"With dozens of casino bonuses to pick from, I suggest that you shop around for the best deal. Casinos occasionally provide state specific offers for players which can provide more value than a usual sign-up bonus. In other cases, such as Borgata and Wheel of Fortune, some offers are only available in specific states like New Jersey".

Our experts use a 25-step review process to rate online casinos, so we only ever recommend the best gambling sites. We cover everything from US regulation and data protection to bonus offers. If any casinos fail to deliver a safe gambling environment, we add them to a list of sites to avoid.

  Sign-up bonus

  Most casinos offer sign-up bonuses to entice new players to register with them. Welcome bonuses can include no deposit bonuses, deposit matches, and cashback offers.

  For example, a casino site might give you $20 in casino credits just for signing up, on top of matching your first deposit of up to $1,000 with bonus money at a 100% rate. Alternatively, you may get the chance to claim back 100% of casino losses up to $1,000 after your first 24 hours of playing online casino games.

  Free spins are common in some states too. These are complimentary credits for playing online slots without having to spend any of your own money.

• 

  Deposit match bonus

  Plenty of online casinos give new players the chance to boost their bankroll with deposit offers. Most commonly you'll get your first deposit matched with bonus funds at a specified rate.

  For example, a casino might offer you a 100% first deposit bonus of up to $1,000. That means your first deposit of up to $1,000 will be matched at a 100% rate. Alternatively, you might be offered a 50% deposit match, which sees half of your initial deposit matched with bonus money.

  It's worth looking out for deposit bonus codes that you must enter to claim your bonus amount. These can sometimes be used across multiple deposits to keep topping up your bankroll.

• 

  No deposit bonus

  No deposit bonuses are some of the most sought-after online casino promotions available. As the name suggests, you'll get a reward without even funding your account.

  Examples of no deposit bonuses include receiving $20 in complimentary bonus funds or 50 free spins on the house. These let you play online casino games without putting any of your own money at risk.

  However, no deposit bonuses shouldn't be seen as completely free. You'll have to follow the terms and conditions of the online casino promotion to withdraw your bonus, including meeting wagering requirements and making a real money deposit.

• 

  Cashback bonus

  Some bonus codes for online casinos activate cashback offers. These allow you to claim back a percentage of your net losses after a specified time period.

  Some of the latest casino bonus codes allow you to claim back 100% of your net losses up to $1,000 after your first 24 hours of play. For example, you might deposit $500, play online casino games, win $100, but lose $200. In this case, you'd be refunded $100.

  The best online casinos will refund your money as cash. In other cases, you'll get bonus money, which is subject to reasonable 1x playthrough requirements.

Although the biggest bonuses are reserved for new players, existing players can also claim promotions at their respective online casinos in the US. These promotions typically do not need the use of casino promo codes and only require an opt-in from players. Below we've summarized a few of the most popular promotions for existing customers.

• 

  Rewards programs

  The biggest US gambling brands operate online and at land-based casinos across the country. Their rewards programs recognize loyalty, offering a whole host of online and in-person benefits.

  Let's take a look at Caesars Rewards, as an example. Caesars offers its players the opportunity to build up Reward Credits by gambling in person and online, as well as by visiting their entertainment venues and partners.

  The points you build up in the six-tier system can be redeemed for rewards. These range from free play credits, through discounted hotel stays, all the way up to invitations to exclusive events.

• 

  Weekly promotions

  Online casinos keep existing players happy by offering them weekly promotions that are updated on a regular basis. This can include promoting new games with the offer of bonus money being up for grabs.

  For example, a promotion might include placing wagers on a newly-launched online slot. In return for wagering a set figure of, say, $30, you'll receive $10 in bonus funds.

  You'll get to keep any winnings you make from playing the slot game, as well as boosting your bankroll with a tidy bonus. Just keep in mind your bonus funds will have terms and conditions attached to them.

• 

  Refer-a-friend

  Online casinos are always on the lookout for new players and will reward existing customers who bring them aboard. Sites will incentivize you to do so by offering you a bonus.

  If a friend uses your referral link to sign up with an online casino and then makes a deposit, you'll get bonus funds added to your bankroll. The maximum amount we've seen is $50, so it's worth shopping around to find the best offers.

  Your bonus will of course come with terms and conditions. Plus, it's worth bearing in mind the promotion will only be valid if you invite someone who doesn't already have an account with your chosen casino.

Terms and conditions for existing and new bonus codes can be difficult to decipher at times, so we always deliver a snapshot of the key terms that you have to know as a player.
