Different Types of Online Casino Bonuses Explained (2025 Guide)

Nothing beats getting rewards on top of rewards, and that’s one of the best parts of playing at online casinos—the freebies you can earn along the way. They come in all different shapes and sizes, some with bonus codes, others requiring opt-ins, and yet others finding their way into your email inbox. 

Here, we look at the various online casino bonuses you can expect to find, from enticing welcome bonuses to attract you through the doors to free spins, deposit matches, and cashback rewards based on your gambling activities.

Welcome Bonuses

As the name suggests, the welcome bonus is your bonus for signing up for an account at a new online casino. There are many different types, from no-deposit bonuses to free spins, deposit match offers, and more. 

Welcome bonuses are sometimes packages that feature a mixture of rewards, or they may extend across your first three or four deposits. What’s key to remember is that they’re only available for new customers, and you can only claim them once per player. 

Deposit Match Bonus

A deposit match bonus is the most common welcome bonus you’ll encounter. It literally means the operator will match a percentage of your deposit in bonus funds, which can effectively double your play allowance if the operator is offering to match 100% of your deposit.

Deposit match bonuses are usually capped at a specific amount, which should be stated clearly in the bonus terms and conditions.

Free Spins 

Free spins as an operator bonus are not the same as the free spins bonus games found within many online slots. Rather, they’re a set number of spins on a particular slot game (or selection of games) with a fixed wager value awarded to players for free. 

Free spins can be part of your welcome bonus or a standalone promotion for returning players and are a fantastic way to explore new games or titles you might not ordinarily play. 

They are often part of a promo run in conjunction with specific slot providers, where you’ll find they are restricted to a set of games, all produced by a particular developer. 

Reload Bonus

Reload bonuses are awarded to returning players when you top up your account balance. Often, this will be in the form of bonus funds and a percentage of your deposit amount, similar to a deposit match bonus. 

Cashback Bonus

A cashback bonus is when a casino operator offers you a percentage of your net losses from a set period returned in the form of bonus funds. Bonus funds are different from your regular balance and cannot be withdrawn. But they can be used to play casino games, with your winnings being awarded as regular cash that you can withdraw once any wagering requirements that may be attached have been fulfilled. 

No-Deposit Bonus

No-deposit bonuses are incredibly rare and, when you do find them, are usually lower in value than the other bonuses mentioned above. Again, it’s all in the name, and these special promos don’t require you to deposit to claim the offer. 

If you do find any no-deposit bonuses, they will likely be rewards for signing up for a new casino account and awarded upon verification of your account. 

Casino Bonuses Terms & Conditions

Regardless of the type of bonus, it’s important to remember that they all come with terms and conditions attached, and you must read through these before claiming any offers to ensure you fully understand what is required of you.

The most common term you’ll encounter is wagering, which is a playthrough amount that you must wager in real money before you can withdraw any winnings accrued from your bonus. This might be, for example, 20x your bonus, which means if your bonus were $10, you’d need to wager $200 in real money before claiming your prize. 

Pay particular attention to the validity period in which you must satisfy the wagering requirement and the games that contribute. Many operators exempt games like blackjack or roulette from contributing to wagering or have a lower percentage contribution. 

It's important to read through the bonus terms carefully before choosing the best bonus for you, as not all will be suitable for all types of casino players.
