Best Deposit Bonuses at US Online Casinos 2025

Best Deposit Bonuses (April, 2025)

Every time a player deposits at the casino, there’s a good chance they can earn more for the deposit. Online casinos are incredibly competitive in securing players’ money, and to make it more attractive, they offer all kinds of deposit bonuses and freebies.

On this page, we’ll show you some of the best deposit bonuses at online casinos in 2025, tell you how they work, how to find the best bonuses and explain how the terms and conditions make some deposit bonuses better than others.

We'll also list the online casino deposit bonus codes required to claim the best deposit bonuses at our top sites. Buckle up, and let's go!

The Cash Match Deal Welcome Deal

Welcome bonuses are the best first deposit casino bonus players can secure at any online casino. Most sites offer a cash match bonus ranging from $100-1500, so a lot can be gained for players who deposit from the start.

A cash match deposit bonus matches a player's first (and sometimes consecutive bonuses) by 100%. So, if you deposit $500, the casino will give you $500, and your bankroll will start at a tasty $1000. Deposit welcome deals come with wagering requirements and other conditions, which we’ll explain shortly.

The Cashback/"Risk-Free" Deposit Bonuses

Cashback deposit bonuses are becoming more popular and widely available. With this deal, the casino refunds any losses made during a specific period. This type of deposit bonus can be offered as a new player welcome offer (typically, players receive between $100-500 cashback on any losses made within the first 24-72 hours) or as a regular casino deposit deal, like part of a casino loyalty club (players are offered 10-25% of their losses back across each month).

The only thing to be aware of with this deposit deal is that it counts NET losses (the total when the losses are subtracted from the winnings). So, if a player makes more wins than losses, they won’t get any cashback.

For example:

• You deposit $100 and lose $30, but win $200 = no cashback.
• You deposit $100 and lose $100 dollars = $100 cashback.

Cashback deals usually do not come with wagering requirements, as the casino is refunding players' money and not giving them any funds upfront. Find out more about cashback casino bonuses on our dedicated page!

Ongoing Online Casino Bonuses

After the welcome offer, depositing players can make the most of any online casino bonus offered in conjunction with a deposit. Here are some of the most common at US gambling sites.

Reload Deals

Reload deals offer players who make consecutive deposits a cash match - just like the cash match welcome offer - but the percentage match is usually lower, around 20-50%. Example: If a player deposits $20 using a 20% cash match, the casino will give them $4 on the house, and the total deposit is $24.

Casino Loyalty Clubs

Casino loyalty clubs are created for players who deposit and use online casinos regularly. They offer rewards in return for deposits and gameplay. Players collect the points to climb tiers and gain monthly rewards, like free spins, cashback, discounts at land-based casinos, and other bonuses.

This casino deposit bonus best suits players who spend money and have a more flexible budget, as the best rewards are earned in the higher tiers, but some clubs are open to all players to enjoy some form of bonus.

If you want to assess the different loyalty clubs offered at US online casinos, reading our guide to Casino Loyalty Clubs is a must.

Free Spins

Free spins are another tempting ongoing bonus for depositing players. When a free spins promo is available, players must reload their casino account to claim the bonus. This type of deal is often launched when the casino promotes a new game or at a particular time of year, say Christmas, and wants to give depositing players that little extra freebie.

When looking for the best free spins offer, check the bet level of each spin, any max win rules, and the number of free spins allocated.

Prize Giveaways/Tournament Tickets

Online casinos are always looking for ways to increase the thrill factor for players. To achieve this, some US gambling sites run prize giveaways or give depositing players free tournament tickets. It usually works something a little like this:

The US online casino is running a particular tournament or giving away a prize. Each player who deposits $20+ in May will get one raffle ticket or entry to the contest. The more a player deposits, the more tickets they get and the bigger the chances of winning the prize!

What is the Best Deposit Bonus at Online Casinos?

Assessing the Worth of a Bonus

For players who prefer to assess the terms and conditions independently, here's what to look for.

• The Bonus Amount: Look at what the casino offers and how much you must deposit to get the deal. Is the deposit worth the bonus, and is it a good deal for your budget and playing style?

• The Wagering Conditions: Also known as the play-through requirement, these state how many times you must wager a bonus before withdrawing any winnings made with the bonus. They usually only apply to bonuses where the casino gives you money.
  The best online casinos in the USA, like BetRivers and FanDuel, have 1x wagering requirements. Still, the median wagering requirement is 10-15x. To calculate the wagering requirement, multiply the bonus amount by the wagering requirement; that’s the amount you’d need to spend if you wanted to withdraw anything you won with the bonus. In some cases, like DraftKings, casinos may state the requirement is a pre-wagering requirement, meaning you must meet the spending amount to unlock the bonus.
  Always ensure you can meet the wagering requirements before taking a bonus in case you score lucky and win big while playing with bonus money. And if the casino states the wagering requirement is a pre-wager restriction, consider the spending implications carefully.

• Excluded Games/GCP: The casino may exclude certain games from a casino deposit bonus, state that players can only use the bonus to play a specific game (see free spin bonuses), or include game contribution percentages (GCP).
  GCP says how much a particular game contributes to the wagering requirement (slots are usually 100% and table games around 10-25%). While checking this, note any max bet/max win conditions. For example, casinos always give free spins at a certain bet level, like $0.10 per spin, and welcome deals may state that you cannot make a bet over $5 per round or hand when using the bonus.
  Below is an example of the GCP rules at DraftKings Casino.

• Excluded Payment Methods: Some US online casinos list that players may only use certain payment methods when claiming a deposit bonus. Do a quick check to see if this condition exists. If it does, make sure the payment method you want to use is not excluded.

• Time Limits: Lastly, online casinos usually have time limits for using a deposit bonus, which are also listed in the terms and conditions. Players must ensure that the listed time limit allows them enough time to use the bonus and complete any other requirements, like the wagering conditions.

Why Do Bonus Terms Matter?

Not only can the terms change the value and use of the bonus (wagering requirements can make bonus winnings unattainable, GCP instructs the best way to use a bonus, etc.), but if you break the terms, you'll lose the bonus AND any winnings you've made using it. This is called a bonus forfeit.

Is It Worth Taking a Casino Bonus?

Deposit bonuses can be great deals, but only if players know what they are getting into and can meet the terms and conditions. We'd never take a bonus with wagering requirements higher than 15x or one that excluded slot games. That's because we like to play slots and don't spend large amounts at the casino. We look for high-quality slot and deposit deals with no wagering bonuses or very low wagering requirements.

It's important to acknowledge that bonuses are a player retention tool, but they're also designed to ensure casino members enjoy playing at a site. Casino bonuses are well worth taking so long as you know your playing style, understand bonus terms, and find matching offers.

Do I need a Casino Deposit Bonus Code to Claim a Deal?

A casino deposit bonus code is a series of letters and numbers like BetRivers Casino’s 250MATCH code. Casino bonus codes tell the casino which bonus a player wants to claim and that they qualify for it (because they have the code).

Nowadays, casino deposit bonus codes are becoming less commonly used. This is good news because it means rather than hunting for casino promo codes; you can simply click on any of our casino links when you’ve found a bonus you want to claim.

How To Claim a Casino Deposit Bonus

1. Go to the casino's promotion page.
2. If a bonus you want to claim.
3. Read the full terms.
4. Click opt-in.
5. The casino will automatically transfer you to the cashier. Input your deposit amount and confirm the transactions.
6. Wait for the bonus to arrive and start playing!
