What Is a Deposit Bonus?
A deposit bonus is a type of promotional offer provided by online casinos to encourage players to sign-up, or make a deposit into their accounts. A deposit bonus usually matches a player’s deposit by a percentage – often 100%, but sometimes more, or less. For example, if a casino offers a 100% deposit bonus up to £200 and a player deposits £100, the casino will add an additional £100 in bonus funds, giving the player a total of £200 to play with!
Deposit bonuses are usually available to new players as a welcome offer, but many casinos also provide them to existing customers as part of ongoing promotions, too – usually known as reload bonuses.
How We Review Casinos
Here at KasinoBonus, we take a very player-focused approach to all our casino reviews. In fact, our in-depth reviewing process is far more comprehensive than most of our competitors—and the main reason for this is the fact that we actually sign-up, deposit, and play at all of the casinos we review.
Some of the factors we look at when reviewing online casinos include:
- Licensing and security
- Payment methods (and cashout speeds)
- Customer support facilities
- Game variety (and which software providers are available)
- Bonuses and promotions (including a look at the terms and conditions)
- And much more!
Types of Deposit Bonuses
Deposit bonuses come in a LOT of different forms, and no matter what type of player you are, you’ll find one that suits you! Below, I’m going to explain some of the most common types of deposit bonuses you’ll find online today.
Welcome Deposit Bonus
The most common type of deposit bonus is the welcome bonus, which is offered to new players when they sign up. These bonuses typically match your first deposit by 100%, 150%, or even 200%—giving you extra cash to play with! Some casinos go one step further, too, and pair these matched deposit bonuses with other perks like free spins or even cashback!
Reload Deposit Bonus
A reload bonus is a deposit offer available to existing players. These bonuses encourage you to make additional deposits by offering extra funds or free spins—often on your second, third, and fourth deposits. Sometimes, you’ll need to enter bonus codes to activate them.
High Roller Deposit Bonus
Fairly self-explanatory, high roller deposit bonuses are special promotions designed for… high rollers. These bonuses are often available in much larger amounts, like the 400% deposit bonus offered at select casinos.
No Wagering Deposit Bonus
A no wagering deposit bonus is one of the most player-friendly promotions available. With this type of bonus, any winnings you earn are paid in real cash, meaning you can withdraw them immediately without having to meet any wagering conditions. Some sites offer these as non sticky bonuses, which further improves flexibility.
Free Spins Deposit Bonus
Some casinos offer free spins as part of a deposit bonus, either alongside a match bonus or as the main reward. For example, a casino might give you 100% up to £200 plus 50 free spins on Starburst. In rare cases, you may even come across offers like a 500% deposit bonus combined with spins.
Deposit Bonus Terms and Conditions
All types of deposit bonuses come with some forms of terms and conditions, and it’s pretty important to be aware of what these terms are before you begin playing. Below, I’m going to walk you through some of the most common terms you’re likely to find when claiming UK deposit bonuses.
- Wagering Requirements. One of the most important aspects of a deposit bonus is the wagering requirement. This dictates how many times you must wager your bonus before withdrawing any winnings. For example, if you receive a £100 bonus with a 35x wagering requirement, you must place £3,500 in bets before cashing out. Some casinos offer low or no wagering bonuses, but some can go up to as high as 70x!
- Minimum Deposit Amount. Most deposit bonuses require a minimum deposit to qualify. This amount typically ranges from £10 to £20, depending on the casino. However, some specific promos—often high roller or reload bonuses—require a minimum deposit of sometimes £100 or more, so it’s always worth checking this before you join a casino!
- Bonus Expiry Date. Most deposit bonuses must be used within a certain time frame. This usually includes both playing with the bonus funds, and completing the wagering requirements. If you don’t complete both elements within the time frame given, your funds are likely to be forfeited.
- Game Restrictions. Not all games contribute equally to wagering requirements. Slots usually count 100%, while table games like blackjack and roulette may only contribute 10% or not at all. Some slots may be excluded from the bonus entirely, though, due to progressive jackpots or very high RTPs, so this is always something that you should check before you begin playing with your bonus.
- Maximum Win & Withdrawal Limits. Some deposit bonuses impose a maximum win limit, meaning that you’re limited to winning a certain amount of money. The chance of there being a maximum win limit increases significantly if you claim a no-deposit bonus. Welcome bonuses, for example, rarely have this term attached—thankfully.

Terms and Conditions
Before claiming any deposit bonus, we strongly recommend taking time to read through the terms and conditions – as there will always be rules and restrictions you’ll need to follow while playing with your bonus funds. Below are the most common terms to look out for:
- Wagering Requirements: Most deposit bonuses require you to wager the bonus (or bonus + deposit) a certain number of times – commonly 35x, but some casinos can impose wagering requirements of as high as 60x!
- Minimum Deposit: You’ll need to make a minimum qualifying deposit which, for deposit bonuses, tends to be £10 or £20.
- Game Restrictions: Not all games contribute equally to wagering. Slots usually contribute 100%, while table games or live dealer games might contribute far less – or be excluded entirely!
- Maximum Bet Limits: While using bonus funds, there is often a cap on how much you can bet per spin or round – often £5 – and if you breach this cap, your bonus may be forfeited entirely!
- Withdrawal Limits: Some deposit bonuses may have a limit on how much you can actually win – but this is far more common with no-deposit bonuses.
How to Claim a Deposit Bonus
Claiming a deposit bonus is usually a quick and simple process, whether you’re a new player signing up or an existing user taking advantage of a promotional offer. The following steps will apply to most online casinos:
- Register an Account: Sign up at the online casino offering the deposit bonus. Ideally, choose one of the casinos listed here at KasinoBonus.
- Verify Your Account: Some casinos may require email or phone verification before allowing deposits or applying bonuses – and this will always be required for UK-based players.
- Choose the Bonus: Navigate to the promotions page or deposit section and select the deposit bonus you want to claim. Some casinos offer multiple bonuses, so be sure to pick the right one!
- Enter a Bonus Code (if required): If the bonus requires a promo code, enter it in the appropriate field when you’re making your deposit.
- Make a Qualifying Deposit: Deposit the minimum amount required to trigger the bonus – this amount varies depending on the casino and promotion, but it’s usually £10 or £20.
- Start Playing: Once the bonus funds have been credited to your account, it’s time to begin playing – good luck!
