"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.

Generally, there are four types of casinos bonuses on offer: sign-up bonus, deposit match bonus, no deposit bonus, and cashback bonus. Below we breakdown each type of bonus and how they work:

• 

  Sign-up bonus

  Sign-up bonuses, also known as welcome bonuses, can come in several forms, including no deposit bonuses, deposit matches, cashback offers, and free spins. For example, a casino might give you $20 in casino credits just for signing up, on top of matching your first deposit of up to $1,000. 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.

• 

  Deposit match bonus

  Online casinos often offer a 100% first deposit bonus up to $1,000, meaning they’ll match your initial deposit. Alternatively, you might be offered a 50% deposit match, which sees half of your initial deposit matched with bonus money.

• 

  No deposit bonus

  As the name suggests, a no deposit bonus lets you claim a reward without funding your account. Common examples include $20 in bonus funds or 50 free spins — giving you the chance to play without risking your own money.

  Like all bonuses, no deposit offers come with terms and conditions. To withdraw any winnings, you’ll usually need to meet wagering requirements and make a real-money deposit.

• 

  Cashback bonus

  Some online casino bonus codes unlock cashback offers, such as 100% back on your net losses up to $1,000 after your first 24 hours of play. For example, if you deposit $500, win $100, but lose $200 overall, you'd be refunded $100.

  The best online casinos refund cashback as real cash. Others may issue it as bonus money, usually with a low 1x wagering requirement.

Most promotions for existing players don’t require casino promo codes — a quick opt-in is usually enough. Below, we’ve highlighted some of the best ongoing offers for returning players to enjoy right now.

• 

  Rewards programs

  Loyalty pays off — especially with the top US gambling brands. Their rewards programs offer a wide range of online and in-person benefits designed to recognize and reward loyal players.

  Take Caesars Rewards, for example. Players can earn Reward Credits by gambling in person or online, as well as by visiting Caesars’ entertainment venues and partner locations. The six-tier system lets you climb the ranks and redeem points for perks like free play credits, discounted hotel stays, VIP access, and invitations to exclusive events.

• 

  Weekly promotions

  Online casinos keep things exciting with weekly promotions. These deals often feature new slot releases, seasonal events, or themed tournaments. For example, you might get $10 in bonus funds for wagering $30 on a brand-new slot. You keep any winnings, and the bonus gives your bankroll a nice boost.

• 

  Refer-a-friend

  If you’re enjoying a casino, chances are your friends will too — and many casinos will reward you for sharing the experience. Most sites offer bonus funds when someone signs up using your referral link and makes a deposit.

  You can earn up to $100 per friend, depending on the site, so it’s worth comparing a few to find the best deal. Just keep in mind that the bonus only applies if your friend is new to the casino, and comes with terms and conditions.

When you sign up for a casino bonus, it’s important that you understand the terms and conditions. We know reading through T&Cs can be confusing at times, so we’ve put together a quick summary of the most common ones we’ve seen to help you spot the key details.
