The Best Casino Welcome Bonuses in 2025

A welcome bonus is often the best bonus you’ll be able to find at an online casino, but you can claim it only once. Many players may rush to grab welcome bonuses that seem appealing, but there are several things you should know before making a big deposit.

Below, you’ll find some of the best casino welcome bonuses, and we’ll also offer some insight as to what to look out for and how to judge if a casino bonus is right for you.

What Is a Welcome Bonus?

A welcome bonus is a one-time bonus offer players can claim when they sign up at a new casino. 

In short, this is what distinguishes welcome bonuses from other bonus offers:

• They can be claimed only once.
• They can only be claimed with your first deposit (or several, if the offer consists of multiple bonuses).
• They tend to have more generous terms.
• They can come in the form of deposit matches, free spins, or even no deposit bonuses.

Most commonly, a welcome bonus is a large deposit match with a side of free spins. However, casinos might also offer different types of high-value welcome bonuses, such as smaller deposit matches with lower wagering, or no deposit free spins.

The bottom line is, a welcome bonus will likely be the highest-value bonus at most online casinos. And since you only have one chance to claim it, it’s important to know what makes a good welcome bonus.

How to Claim a Welcome Bonus

Claiming a welcome bonus at a casino is a simple matter, and here’s what it usually looks like, step by step.

• Step #1: Sign up at the online casino. 
• Step #2: Go to make your first deposit, either through the cashier section or the Deposit button in the lobby.
• Step #3: Select your deposit method of choice and specify the deposit amount. 
• Step #4: Activate the welcome bonus by selecting it from a bonus card OR inputting the bonus code from the promotions section.
• Step #5: Finalize and confirm your deposit.

Keep in mind that this may differ slightly from casino to casino, and they might prompt you to opt in for the welcome bonus even while you’re making an account.

Pros & Cons of Using Welcome Bonus

Before we go into more detail, here are the bullet points for the general pros and cons of welcome bonuses at online casinos:

Welcome Bonus Pros	Welcome Bonus Cons
✅ Usually a huge boost to your bankroll ✅ Can be a deposit match, free spins, or both ✅ May include no deposit offers	❌ Can only be claimed once ❌ Wagering may be difficult to complete ❌ Some deposit methods may be excluded

Welcome Bonus Wagering Requirements

Most online casino bonuses come with wagering requirements. This is the number of times you have to wager the bonus amount before it’s converted into real money.

For example, if you get a 100% match on your $100 deposit and the wagering requirement is 30x the bonus amount, you need to wager $100 a total of 30 times. In other words, you have to wager $3000 before the bonus money is converted into a real money balance.

Keep in mind: some casinos require you to wager your combined bonus and deposit amount, instead of just the bonus amount. Always be sure to double-check this, especially if the wagering terms seem too good to be true. 

What Are Cashable and Non-Cashable Welcome Bonuses?

Welcome bonuses can be divided into two categories: cashable (non-sticky) and non-cashable (sticky).

Cashable welcome bonuses allow you to withdraw the full bonus amount and any winnings once you meet the wagering requirements. Non-cashable bonuses allow you to withdraw only the bonus winnings but not the bonus amount itself.

While cashable bonuses may seem better at a glance, keep in mind that non-cashable bonuses usually offer much bigger amounts of bonus money to play with. This means a larger bankroll to play with and it just might be easier to meet the wagering requirements. 

What’s the Maximum Welcome Bonus You Can Get?

If you’re wondering how big welcome bonuses can get, that’s a bit tricky to answer, since there are two factors at play.

First, there’s the deposit match percentage, i.e., how much bonus money you get relative to your deposit. Some welcome bonuses can go as high as 400% (e.g., deposit $100, get $400 in bonus money). Casinos may go even higher, but keep in mind that such generous matches are usually offered as part of a sticky bonus.

Second, there’s the maximum matched amount, a hard cap on how much bonus money you can get. For example, if the casino offers a 400% match up to $400, you’ll only ever get a maximum of $400, regardless of whether you deposited $100 or $1000. There’s no hard cap on how high casinos can theoretically go on this front — many welcome offers and high roller bonuses go well over a thousand dollars.

In the end, always remember: just because the bonus looks good at a glance doesn’t mean it actually offers good value. Always read the terms carefully and make sure there are no ridiculous terms or “gotcha” rules meant to trick you out of your money.

Types of Welcome Bonuses

Welcome bonuses come in a number of shapes and sizes. 

The most common type of welcome bonus you’ll encounter in the wild is a simple and straightforward deposit match. You make a deposit, the casino matches a certain percentage of your deposit in bonus money.

Then, there are also free spins welcome bonuses. Here, the casino credits your account with a number of free spins for specific games, so long as you meet the minimum deposit requirement. Once you use them up and clear the wagering requirements, the winnings are yours to keep. Many casinos offer both a deposit match and free spins as part of their welcome package.

Finally, there are no deposit welcome bonuses. These are usually offered as an extra incentive next to a regular welcome bonus — for example, you might get free spins or some bonus cash simply for signing up at a casino.

No Deposit vs. Deposit Welcome Bonuses

The difference between no deposit and deposit welcome bonuses is in the name: one can be claimed without making a deposit at a casino, and the other is granted with a deposit.

In practice, no deposit bonuses differ in a number of key areas:

• They usually have stricter terms,
• They come in smaller amounts, and
• They have maximum cashout caps.

Naturally, casinos aren’t eager to give out free money, and no deposit offers may be more difficult to cash out. Still, if you have nothing to lose by claiming one, you might as well give it a shot.

Common Mistakes When Using Welcome Bonuses

Since welcome bonuses are one-time, high-value promotions, it’s important to make the most of them. Here are some common mistakes players make that you should avoid if you want to increase your chances of cashing out.

Mistake #1: Not Reading the Terms

We always repeat this like a broken record but it can’t be said enough times: always read the terms! 

If you’re new to the whole online casino thing, here are the key terms to consider when claiming a welcome bonus:

• Wagering requirements: The lower, the better. Anything from 40x to 50x is solid, 35x is great, and anything above 60x might just not be worth the risk. And if it’s under 35x, it’s likely a great deal — just make sure you confirm it’s applied to the bonus amount, not the combined amount of the bonus and your deposit.
• Wagering time limit: You’ll have a limited amount of time to meet the wagering requirements, and it normally ranges anywhere from 5 days to 30 days. Whether a time limit is good depends entirely on the deposit amount. Sure, 5 days is more than enough for a $20 cash bonus, but way too short for a $1000 deposit match.
• Maximum cashout: Ideally, a deposit bonus should have no cap on how much of your winnings you can withdraw. If it does, rethink how much money you’d be willing to risk if your return is capped at like 5x after you wager it dozens of times over.
• Restricted payment methods: Sometimes, certain deposit methods may be excluded by the casino due to higher risk of bonus abuse by players. E-wallets such as Skrill and Neteller often find themselves on this list.

Mistake #2: Playing the Wrong Games

There are also some key terms to keep in mind when it comes to games:

• Wagering contribution: At most casinos, not all games will contribute equally to the wagering requirement. For example, slots may contribute 100% of your bet, while table games may only contribute 20%, meaning you’d need to wager 5 times more money if you play table games with your bonus. 
• Excluded games: Many casinos have a list of specific titles they exclude from bonus wagering, and it’s usually the slots with high RTP. So, always double-check if the game you’re playing is on that list.
• Free spins slots RTP: Whenever you get free spins, check the RTP on the slots they’re credited for. As a rule of thumb, a slot should ideally have a RTP of 96%, so if it goes far below that, the free spins bonus might not be offering such good value as it appears.

Mistake #3: Not taking breaks

Unless you’re dealing with a very small welcome offer, you’re unlikely to complete the wagering in one sitting. There’s a reason casinos give you 2-4 weeks when it comes to more substantial deposit matches, so be sure to take a break when you feel tired or things start getting stressful.

If you keep playing past the point where the experience starts feeling stressful instead of fun, you’re prone to making impulsive decisions, and it can send your balance spiraling down the drain. Take it from someone who’s lost more money on blackjack this way than they’d like to admit.

Mistake #4: Chasing Losses

Sometimes, luck is just not on your side. It never feels good, and it’s even worse if it feels like a great one-time bonus went to waste. However, depositing more to “win back” the money you lost is usually a recipe for disaster.

Sure, the idea of getting your money back and at least breaking even sounds good, but if you already feel so bad about losing your initial bankroll, think about how you’ll feel if you lost even more money chasing that loss. 

Bottom line, to repeat the responsible gambling mantra: only gamble with money you’re willing to lose.
