Casino bonuses come in different forms whether they be free spins, deposit bonuses, loyalty points or other.
Below is a list of the most common types of casino bonus to help you understand how they work for when you are offered them.
The vast majority of online casinos offer new customers bonuses as an incentive to register an account and bet with them. Most of these casinos require you to make a deposit using your own money in order to receive the bonus but some of them reward new customers with bonuses simply for registering an account. These offers are called ‘No Deposit Casino bonuses’ and require no deposits or wagers to be made.
Casino bonuses no deposit offers are not as common as bonus offers that require a deposit but there are some of them about which you’ll find in the list above on this page. They are usually of a smaller value than deposit bonuses but still worth claiming as they’re risk-free.
No deposit casino bonus offers are perfect for anyone looking to try a new online casino without depositing their own money and for anyone looking for a risk-free chance of hitting a big win and making a cash profit!
Similar to casinos offering new customers no deposit bonuses, some casinos give new customers no deposit free spins. These offers are quite common and used as an incentive to get you to register an account.
No deposit free spins are credited when you create an account with an online casino and are usually available on selected slots.
The number and value of the free spins will vary depending on the casino offering them and the slots which they’re available to be used on but just like with the free bets, they’re risk-free so definitely worth claiming.
Some free spin no deposit offers have winning caps applied which means that there is a maximum amount you can win from using them. However, not all do and these offers provide an opportunity to win potentially huge amounts with no risk at all. Imagine hitting a jackpot win on a slot without having to deposit a penny!
Welcome bonuses are the most common type of casino bonus you will come across and are offered to new customers at the vast majority of online casinos.
Online casinos use welcome bonuses as a way to attract new customers and encourage them to sign up and make a deposit. They’re great for the player as they get more money to play with and great for the casino as they have a new customer.
Welcome bonuses themselves can come in various forms and often have different T&Cs. The most common type of welcome bonuses are deposit bonuses such as ‘100% deposit bonus up to £100’ or ‘200% deposit bonus up to £300’. These offers often sound too good to be true but many of them have wagering requirements which must be met before you’re able to withdraw the bonus or any winnings generated from using it.
Online slots are one of the most popular games at online casinos and there are thousands of them available. As such, online casinos often offer customers free spins as either part of a welcome offer or as part of a promotion for existing customers.
Depending on the offer, free spins may or may not come with wagering requirements. If they do, you may have to wager any winnings generated from using the free spins a number of times before being able to withdraw them. Free spins may also be available to use on selected slots only so always read the terms of the offer first.
Welcome bonuses are intended to attract new customers but online casinos need to retain those players and so reload bonuses are often awarded on a regular basis. They generally work the same as welcome bonuses but are usually of less value.
For example, a casino may offer a 200% bonus up to £300 for new depositing customers and offer them a 25% bonus up to £50 on their second or third deposit.
Another way online casinos reward their players is via loyalty points. Not all online casinos have a loyalty scheme but with the ones which do, players accumulate points with every wager they make with the casino. They can then exchange the points that they have collected for rewards such as free spins, casino bonuses and even cash.
Over recent years, the popularity of live casino games has increased dramatically with new games from providers such as Playtech and Evolution Gaming emerging on a regular basis. As these games have become so popular, online casinos have started to offer live casino bonuses to players. Live casino bonuses can be used on a selection of live games such as live blackjack, live roulette or the several live host games which are now available such as Monopoly Live, Crazy Time, Deal or No Deal Live and Dream Catcher.
With the vast majority of the population in developed countries now having smartphones, it’s never been easier to bet online. This has lead online casinos to offer customers mobile casino bonuses to encourage them to wager using smartphones or tablets.
With mobile casino bonuses, players usually have to qualify for the bonus and also use the bonus by playing games on their mobile device.
Also referred to as ‘casino bonus codes’, promo codes are sometimes required to participate in an offer.
You may need a bonus code for both welcome offers and reload offers. If a code is required, it should be stated clearly in the terms of the offer. If we have the offer listed here on WhichBookie, we will also display it in the steps to claim the bonus. Casino promo codes existing customers can often be found on the promotions or offers page of the online casino and so it’s worth keeping an eye on these pages on a regular basis.
The majority of casino bonuses come with wagering requirements. These require the player to wager the bonus amount a certain number of times before the bonus and any winnings generated from playing with the bonus can be withdrawn.
If wagering requirements were not applied to casino bonuses, players could simply make a deposit to claim the bonus and then withdraw their original deposit + the bonus amount.
Wagering requirements differ between casinos and the bonuses which they offer. They can range anywhere from 1x to 99x and can apply to the bonus amount or the bonus + deposit amount.
Example: A casino is offering a 100% deposit bonus up to £100 with 35x wagering on the bonus.
This means that the player must wager £3,500 (£100 x 35) before they can withdraw the bonus.
Example 2: A casino is offering a 100% deposit bonus up to £100 with 35x wagering on the deposit + bonus.
This means that the player must wager £7,000 (£100 x 35 + £100 x 35) before they can withdraw the bonus.
With many casino bonuses, not all games contribute 100% towards wagering requirements. Much of the time, online slots will contribute 100% but table games which have a much lower variance such as Blackjack and Roulette often contribute a lot less which means that players who are wagering their bonus on these games, must wager more than initially thought.
Example: A casino is offering a 100% deposit bonus up to £100 with 35x wagering on the bonus. Slots contribute 100% towards wagering whereas blackjack contributes 10%.
Wagering on slots: Player must wager £3,500 to clear the bonus
Wagering on blackjack: Player must wager £35,000 to clear the bonus
The UK Gambling Commission has announced that from December 2025, all online casino bonuses offered by UK-licensed operators will be subject to a maximum wagering requirement of 10x the bonus amount. This change is designed to improve transparency and fairness, making it easier for players to understand bonus terms before they opt in.
Previously, some bonuses came with wagering requirements as high as 30x, 40x or even 60x, making it difficult, if not near impossible, for players to withdraw any winnings. By capping wagering at 10x, the Gambling Commission aims to reduce the risk of harm to players, particularly casual users who may be unfamiliar with the high wagering requirements in the T&Cs.
The rule change is expected to encourage operators to simplify their bonuses and focus on player trust. However, it may also lead to smaller bonus values being offered overall, as operators adjust their promotions to stay profitable within the new limits.
Importantly, the new rules also ban cross-vertical bonuses, which are offers that require players to wager across multiple product types, such as casino and sports betting. This is just one of several actions the UK Gambling Commission has put in place in a bid to creating a safer, clearer and more player-friendly environment for UK-based gamblers.
