What Exactly is a Casino Bonus?
An online casino bonus is simply a certain amount of bonus funds you can wager on games without the need to use your casino cash balance. These offers come in different forms, including bonuses that only qualify through deposits and some that are not set on deposit requirements. Furthermore, there are different types of bonuses, including free spins, deposit match bonus, bonus money, and much more. If you want to play with bonus funds, read bonus terms before claiming your bonus.
The Inner Workings of Casino Bonuses
Online casino bonuses are given in specific numerical values. They are set on particular wagering requirements that need to be met. Wagering/playthrough requirements require you to wager the total value of your bonus a certain number of times (usually x30 or x40) before being able to win and withdraw real money.

How to Choose the Perfect Casino Bonus For You
Casino bonuses come in many different forms and may provide you with more than one form of bonus credit in one package, e.g. Free Spins + Bonus Money + Deposit Match, but you need to consider the wagering requirements that you have to meet with these lavish offers. In some cases, a simple bonus might be a better option; in others, you may benefit from a welcome package. Follow the Casino Legends ‘how to choose the perfect bonus’’ guide below.
Know The Different Bonus Types
There are many different bonuses to choose from, whether you are a new or existing member of an online casino. If you are not aware of the exact type of bonus you are opting for, you may be agreeing to wagering requirements that you can’t meet or waste a chance of winning real money in the long run.
The most useful and common bonuses include the following.
- Welcome Deposit Bonus – May include a combination of types of bonuses
- Match Bonus – Matches your deposited amount by a certain percentage
- No Deposit Bonus – Bonus casino money or free spins without a deposit requirement
- Free Spins – Spin slots for free
Wagering Requirements Explained – Why It's Important
Always consider the wagering requirements before opting for an online casino bonus. Wagering requirements are terms that need to be fulfilled by means of wagering the bonus value a certain number of times before you will be able to withdraw any winnings obtained through the bonus. These wagering requirements are also tied to timelines wherein the requirements need to be met before they expire.
Examine Game Restrictions
Some bonuses may not be eligible for use with certain games and can only be used on certain games. Further restrictions on games may also include win limits and wagering limits that are put in place as part of the bonus terms.
Look at Bonus Value and/or Match Percentage
Any casino bonus will either be a value in bonus money, a certain number of free spins, or a bonus match where the value of your deposit determines your bonus value. If you are looking for a bonus that will last you a while (duration before expiration), then a deposit match bonus may be a good option, but be prepared to be able to meet the wagering requirements.
Read and Understand the Terms and Conditions
Besides wagering requirements and game restrictions, bonus terms are in place that you need to consider before opting in for an offer. Bonus terms are set out by online casinos as a means of a ‘’qualifying’’ agreement. Bonus terms may include having to make a qualifying deposit with a certain payment method, make a deposit of a certain amount, have no other active bonuses, and more. These terms are in place to ensure that both the casino and the players benefit from the bonus.
Check for Expiry Dates
Expiry dates are put in place for you to use as a timeline in which the bonus wagering requirements need to be met. If you do not finish the wagering requirements before the expiration date, you will lose all winnings obtained through the bonus as well as all remaining bonus money or free spins.
Research the Casino's Reputation
The casino’s reputation should be at the top of your concerns. If you do not know the casino but are intrigued by one of its sign-up offers, you should research the casino to ensure they are licenced and regulated either by the UK Gambling Commission or the Malta Gaming Authority.
Compare Different Bonus Offers
Some casinos may provide you with an offer that might be more beneficial for your specific needs. As an example, 32Red offers you a welcome offer of 150% Match for deposits up to £150, whereas Unibet offers you a welcome offer of a £40 Casino Bonus with a £10 Bonus. If you are looking to make a small deposit with a potent casino bonus amount, the Unibet offer may be better for you. Whereas if you are looking for an extravagant bonus that will give you plenty of credit to use, then the 32Red offer will be the best option.
At Casino Legends, we strive to assist you in knowing about all the latest bonus offers available and what the benefits of opting in are. Keep an eye on our bonus page for the ultimate bonus offer guides.
Consider Your Casino Cash Balance and Budget
It is vital to always consider your casino cash balance and overall budget before opting for a bonus. Calculating wagering requirements will quickly determine whether you should be making use of a deposit or not. If you can’t afford the bonus playthrough, then consider a different option, such as a no-deposit bonus or free spins offer. If by any means you feel as if you may be paying too much or risking too much of your budget, you can make use of responsible gambling tools to limit your spending. Most regulated and licensed casinos have responsible gambling tools in place.
How Do Casino Bonuses Work?
Casino bonuses work by simply giving you a certain amount of casino credit to use on eligible games and wagers without the need to use your cash balance. In some cases, however, your cash balance will be used as part of the playthrough before the bonus credit is used. All bonuses that require a deposit fall under wagering requirements. This means that if a bonus has a wagering requirement of x40 you will be required to bet x40 on the initial value of the bonus before being able to withdraw real money obtained through the welcome offer. Initially, the bonus value provided to you as part of the bonus may be used on popular casino game titles but is mostly limited in selections. Generally, live table games and progressive jackpots are excluded. If these games are, however, not excluded from the bonus, they may not contribute much to the wagering requirements, which will cause you to take longer to meet the wagering requirements.
How Are Casino Match Bonuses Calculated?
Most welcome bonuses from online casinos include a match bonus or either 150% or 200%. If you are looking for the perfect welcome offer, you may have noticed that with the percentage figures, there may also be a maximum limit on the deposit amount that can be matched. As an example, 32Red’s incREDible Welcome Offer has a 150% match for deposits up to £150.
See examples of what to expect through a bonus match in the table below.
A match bonus provides you with an amount of credit depending on the size of your deposit. It is important to consider that the higher the amount of bonus you get, the longer duration it will take to finish your wagering requirements and start to win real money.

Types of Casino Bonuses and Promotions
An online casino bonus, no matter what type, can greatly enhance your overall gaming experience, yet some may be more beneficial for your own personal needs. Whether you are looking for the perfect start to an online casino, a deposit without the requirement of a deposit, or simply free spins to stick to the slot games, find your preferred offer below.
Welcome/Sign-up Bonus Offers – Best For Newbies
Welcome offers are considered by many UK players to be the best casino bonus type if you are only getting into gaming now or new to a specific casino. Welcome offers are there to help you have the perfect start at the casino and assist in gaining experience with different types of games, or you to test out different strategies. Generally, welcome bonuses require you to deposit to qualify for the offer. This, however, is mostly worthwhile as online casinos do not have very high minimum deposit requirements. Welcome offers may be offered as a Match Deposit Bonus, which matches your deposit amount by up to 200%; meaning, if you deposit £10, you can receive up to £20 free bonus money. This can be seen with the 32Red welcome bonus, where you can get up to a £150 match of 150%.
No Deposit Bonus – Best for Free Gaming
If you are looking to opt-in for a bonus purely for the pleasure of playing casino games without the chance of winning immediate real money prizes, then you will enjoy a no-deposit bonus. No deposit bonuses simply don’t require a deposit and assist you in playing games at no cost. It is, however, important to consider that generally, you will not be able to win real money through a no-deposit bonus, and it would only help as a means to practise games or try new strategies unless there is a wagering requirement which requires you to play through a certain amount and then be able to win real money.
Welcome bonuses generally have free spins attached to them or are available in mini-games that are built into slots. Free spins can only be used on selected slot titles when attached to a welcome bonus or other promotions and may not be used on progressive jackpots ‘’depending on the casino’’.
Wagering Requirements Explained
Online casino bonuses are essentially given out to assist you in having more ‘’play-time’’ which could increase your potential of winning in the long run. Most bonuses have wagering requirements set out that need to be met before you can win and withdraw real money obtained through the bonus credit. Wagering requirements are generally displayed by the number of times the bonus value will have to be played. Generally, wagering requirements need to be played through up to x50. For example, if you receive a £40 bonus with an x50 wagering requirement, you will be required to wager the bonus value x50 before the terms are met.
Bonus Restrictions Explained
Bonuses terms and conditions should always be considered; this includes restrictions in minimum deposits, limits on wins, contributions, and more. Knowing when a bonus will expire, what you need to deposit to qualify, and other factors can assist you in not being disqualified from the bonus before meeting the wagering requirements. Carefully consider the following important bonus restrictions that are generally applied to bonus offers.
Deposit amounts are generally associated with all types of deposit bonuses and may also require the deposit to be made by a specific payment method. Minimum deposits are usually set at low numbers to make it possible for all members to benefit from the offer. Generally, you can expect a deposit bonus to have a minimum deposit amount of £10 or £20. In some cases, the minimum bonus amount may also differ depending on the payment method.
Win limits are put in place by some online casinos to curb the amount you can win while a bonus is active. In some cases, progressive jackpots may be an exception to win limits if they are available as eligible games in game restrictions (discussed below).
Game Selection Restrictions
Game selection restrictions are put in place with most free spin offers and welcome bonuses where bonus money is available to use on games. Generally speaking, most slots are available to play with most bonuses, yet live casino games and progressive jackpots may, at times, be excluded from eligible games. The eligibility also goes hand in hand with wagering requirements, as some games ”excluded games” may not provide anything to wagering requirements.
Game Contributions to Wagering Requirements
Different games may contribute differently towards the bonus wagering requirements and should be considered before you use your bonus money on a game. Table games are generally said not worth playing while a bonus is active as they may only contribute up to 20% or less of the value to the wagering requirements.
Bonus terms usually include time limitations where wagering requirements need to be met. If you do not finish the wagering requirements within the set period, you may lose winnings associated with the bonus money as well as the remaining bonus credit. Expiration dates are usually set at 7 days from when the qualifying deposit was made.
Ability to Withdraw Bonus Money
When you make a bonus qualifying deposit, you will notice both a cash balance and a bonus balance on your profile. The bonus balance is generally never available to be withdrawn, but some casinos may make it possible to withdraw the bonus money as soon as wagering requirements are met. These offers are, though generally, higher in playthrough rates. Mostly, with standard bonus terms, you will be able to withdraw winnings obtained through the bonus money.
Bonus or Total Amount
Some online casinos may stipulate within their bonus terms that wagering requirements are not just set out for the bonus money but rather the full value of your deposit + bonus credit. Thus, the total amount that falls under the wagering requirements should be considered before you opt in for an offer.
Maximum Bet Size
Placing larger bets to reach wagering requirements faster is not always a possibility and will be determined by whether a maximum bet size limit is introduced or not. Maximum bet size limitations limit you from placing larger bets on single wagers or may just be void in contributing to the wagering requirements.
Many casino players make use of specific strategies to enhance their overall experience and provide them with a greater chance of winning. Although helpful, some strategies may be forbidden with certain games, especially common strategies such as making bets on two different outcomes at a table game.

Casino Bonus FAQ
What is a casino bonus?
A casino bonus is simply a form of free credit which you can use on top of your cash balance at the casino, thus providing you with more play-time and a greater chance at placing a winning wager in the long run. Bonuses may, at times, require a deposit, yet some bonuses are known specifically as no-deposit bonuses, which means you do not have to deposit to qualify for the bonus offer.
How Online Casino Bonuses Work
As a new or existing member of an online casino, you will be presented with various offers where you either need to make a deposit or not. Generally, with deposit bonuses, you will need to meet wagering requirements before you can make a withdrawal of your winnings. As an example, if an online casino bonus of £100 bonus money has a wagering requirement of x40 you will need to wager the bonus money amount x40 before your winnings count as real money.
What bonus codes are used to redeem special bonuses?
Bonus codes are available in affiliate programs to provide customers with a special bonus offer not usually available from the particular online casino. Bonus codes are generally found in the form of a string of numbers and letters which you need to enter in the designated code block when signing up with an online casino.
Can I withdraw my casino bonus?
No. Casino credit may not be withdrawn from your casino account as it is purely provided to you as assistance in getting to know games and being able to play longer to have a greater chance at striking luck. Some online casinos, such as 32Red, do, however, provide you with a choice to withdraw winnings obtained through your bonus at the cost of losing your remaining bonus credit.
