The Ultimate Online Casino Bonus Guide
Who doesn't like the idea of getting something for free? When we see the word 'free' anywhere, it automatically catches our eye as we all like to get something for nothing. It makes us sit up and take notice and, more importantly, makes us take action, especially when it comes to free casino bonus offers.
By far and away, the most common way and easiest way for a casino to attract new customers is with the use of casino bonuses and free spins. Not only does this tempt new customers to open up an account, but it also rewards existing customers for their loyalty and high roller customers to stay and keep playing. Not only can casino bonuses help attract new players, but they can also encourage player loyalty and help them to stand out from other popular online casinos, in what is a very crowded market. As soon as you enter any online casino, you will be met with lots of really appealing bonuses and offers, some seemingly too good to be true. However, sometimes, if a casino bonus seems too good to be true, it may well be. Are they actually going to deliver on their promises, or are they there to simply tempt you to part with your hard-earned money?
There are a number of different types of online casinos, all with the specific purpose of attracting and keeping different types of players. However, what they do all have in common is their ability to attract a lot of attention. Because these offers are designed to attract, often the big bold lettering will offer the world, but don't forget to look at the small print as well. Often it is not the large print, but the terms and conditions in small print that are the deciding factor as to whether this is a good casino bonus offer or not. Most casino bonuses have pluses and minuses, benefits and drawbacks, so you need to look very carefully at every aspect of the casino bonus to see what is the best bonus for you and work out how to get the most from it. Are you a high roller playing for high stakes? Are you someone who likes to win little and often with minimal risk? These are all factors in determining the best casino bonuses for you.
The Different Online Casino Bonus Types
As we have stated before, not all online casinos are equal in terms of quality, and the same is true for the quality of the welcome bonus and casino bonuses. However, we have tried and tested out all of the casino bonuses available, here at betandskill.com to make sure that you start your casino journey with the best experience possible. Here, we look at all the different types of casino offers you can expect to find, along with the pros and cons of each.
Different Deposit Bonuses in 2022
As each year comes and goes, online casinos have to keep finding different ways to encourage players to deposit. To do this, they will offer players deposit bonuses, both as welcome bonus offers for new players as well as loyalty bonus offers for existing customers. As such, we have a dedicated team of casino experts that are always digging through all the different online betting sites and casinos to look for the biggest and best casino offers that are around. We look at every aspect of the bonus to make sure that it passes our thorough tests and investigations before we recommend it to our players. Although what you see at first is the quantity of the bonus - big and bold, the true attractiveness and appeal of a casino bonus is actually what is written in the small print - the terms and conditions. What are the wagering requirements? Whether the bonus must be used within a set time period, are the free spins on selected games only? All these bonus terms and conditions are very important, but especially the wagering requirement attached. The lower the wagering requirements, the better!
Free Spins and Bonus Spins Offers
One of the most popular types of games at any online casino is the slot game. As such, there are new and more exciting slots being added to online casinos all the time. In order to encourage players to try out these new slots, online casinos will often offer free spins bonuses. Sometimes these free spins make up the whole of the welcome bonus, but many times the free spins are in addition to a deposit bonus - and called 'extra spins'. The size of the free spins bonus offer can vary immensely, from 20 free spins to 100 bonus spins. These offers will always have a minimum deposit requirement and wagering requirements attached.
The drawback of free spins bonuses and extra spins is that these are only usable on slots. However, if they come as part of a welcome bonus package, then players can use bonus funds to play on the casino games of their choice whilst enjoying the free spins (or bonus spins as many casinos call them) on certain games which they can try out for free. Remember, that not only are free spins for selected games only, but they also have a set value per spin as well as a set time frame which they must be used within. Additionally, it's worth noting that winnings from free spins are generally capped at a certain amount. However, we feel that these are still always worth taking up as you get to play on some of the best new slots without spending your own money... especially when combined with a generous deposit bonus!
Our Top Free Spins Welcome Bonus - Genesis Casino
If you're looking for a quality free spins bonus to start your online casino journey then Genesis Casino is the way to go. As a first deposit new players welcome bonus it is currently offering 100% up to £100 bonus plus 300 bonus spins. Genesis Casino is a quality site, regulated by both the UK Gambling Commission and MGA as well as being audited by eCOGRA. The bonus and free spins are subject to 35x wagering requirements with a minimum deposit of £10. Genesis Casino also offers players an excellent reward scheme and VIP service for its high roller players.
Bonus and free spins -18+ New players only. Full T&C's Apply. First deposit only. Min deposit £10. Max bet using bonus £5. 40 x wagering applies. Bonus valid for 14 days. 30 Spins on Starburst games will be credited instantly + then 30 per day for 9 days. Bonus funds are separate to cash funds. Free Spins valid for 72 hours from credit. Max Free Spins winnings £100. Skrill + Neteller excluded. One bonus offer per player. Always refer to Bonus Terms - www.begambleaware.org • Bonus T&Cs Apply.
No Deposit Online Casino Bonuses
Many players will look for their best casino bonuses to be easy to claim. It doesn't get much easier to claim a bonus than if it's a no deposit bonus. Players simply need to register for an account to claim their welcome bonus - they don't even need to make a first deposit! Generally, no deposit casino bonuses are smaller than standard deposit casino bonuses. What's more, you will often find that the terms and conditions attached are a lot tougher. There may be higher wagering requirements attached to this type of casino bonus.
Indeed, online casinos can't simply give away money. They cannot afford to give players a casino bonus for no money - as well as the winnings that come from this casino bonus. A no deposit casino bonus costs the casino money. However, despite this, we would generally recommend taking up a no deposit bonus, regardless of the size of the actual bonus. This is the perfect way to start playing at a new casino site without having to spend any of your own money - and if you do meet the terms and conditions and wagering requirements, then you even get to keep the winnings!
Our Favourite No Deposit Casino Bonus - Pocketwin Casino
The current Pocketwin welcome bonus for new players is a £10 no deposit bonus. It has 40-times wagering requirements attached and must be used within 7 days. The maximum cash out from this no deposit welcome bonus is £50. T&Cs apply. New players only. 18+. Bonus funds separate to cash funds. Check full terms and conditions.
Cashback Bonuses and Reload Bonuses
These are not designed to be welcome bonuses and are specifically designed for existing customers and to reward loyal players and high roller players. These are aimed at those players that have made a net loss when playing casino games. This is perfect for any player or customer who is having a losing streak and needs a bit of a helping hand.
An example of a reload bonus may be: 20% reload bonus for all live dealer and live casino games up to £50. This means that if you make another deposit of £50 and claim the bonus, then the online casino will give you an additional £10 bonus to play with.
Many online casinos will not attach wagering requirements (or only very low wagering requirements) to these casino bonuses as they are rewarded as a result of a customer losing money.
Our Recommended Cashback Offer - All British Casino
The current casino bonus offer at All British Casino - for new players and existing customers is 10% Cash Back for all losses, which is quite an interesting offer. This means that every time you record new losses, All British Casino will give you a 10% cashback bonus. However, because this is an ongoing offer it is subject to 35x wagering requirements, with further terms and conditions attached.
T&Cs apply. 18+ New players only, min deposit £20, max bet £5 with bonus funds. Max bonus is 100% up to £100. No max cash out on deposit offers. Welcome bonus excluded for players depositing with Skrill or Neteller. Cashback is cash with no restriction. Only bonus funds count towards wagering requirements. Full T&C’s apply • T&Cs ApplyHigh Roller Offers
These are the online casino promotions that are aimed at those 'high roller' players - those that are playing with a bigger budget than the rest. As such, it is not that unusual to see some high roller bonuses going into the £1000s! These are aimed solely at online casino players who have much more disposable income. They also come with very similar wagering requirements attached, and wagering the total amount of these bonuses can often be quite expensive. Often, high roller bonuses will come as a part of the loyalty reward scheme or VIP Players reward program, which is only open to players who have made significant deposits. This will be one of many perks and benefits available to VIPs and high roller players.
VIP Schemes
We also like to see VIP schemes attached to the site as well, to reward those players that keep on spending and playing. These reward schemes are normally split into different levels - and the more you play, the higher your level. As a reward for climbing up the scheme, high roller players can expect benefits such as:
- Bigger and better casino bonuses
- Faster withdrawals and higher withdrawal amounts
- Even better customer support and customer service
- A dedicated VIP manager who is there specifically to help you with anything that you need at the online casino.
Our Recommended High Roller online Casino Bonus - 888casino
888casino is world-famous for offering big bonus offers perfect for high roller players. It offers its players a great reward scheme and VIP service. For new customers, its current welcome offer is a 100% bonus up to £200 plus 25 free spins Full T&Cs apply.
1st deposit only • £20 min deposit • Free spins (FS) expire in 14 days • FS wins capped at €3.75, excl. JP wins, & credited as bonus • Valid for selected games • Bonus wins capped at €500, excl. JP wins • 30x wagering - req. vary by game • Bonus expires within 90 days • Withdrawal terms & T&Cs apply. • Read full T&Cs apply.Regular Bonuses and Daily Offers
As stated, all good online casinos will offer welcome bonuses to get new players through the door. However, these same casinos need to keep their players and stop them from being poached by competitors. In order to do this, many online casinos offer their existing customers a number of regular promotions and daily deals. Generally, because of the nature of these offers, they are always very easy and straightforward to claim, as are the terms and conditions attached to these offers. Normally, you would be expected to either deposit a set minimum amount or play a specific game at a specific time to claim the bonus.
As such, at many of the best online casinos, you can find deals named 'Free Spins Friday' or 'Moneyback Monday'. However, like every other casino bonus, these will come with specific terms and conditions, including wagering requirements and minimum deposits so read the small print carefully.Referral Casino Bonuses
Another way to attract new players to a site is to reward existing players for introducing a new player to their casino site. Normally, the existing referring player would get a referral bonus as well as the new player. This is hugely popular with online casino players as it's so easy to claim. Again, these offers aren't to be found everywhere and as with other casino bonuses, they are highly likely to come with wagering requirements attached.
Raffles, Tournaments and Missions
One very popular way to get your hands on different promotions is by taking part in raffles, tournaments and missions, which sees you face off against other casino players to win bonus, promotions, free spins and more. Although these aren't found in every casino, there are a number of gamification casinos that use these not only to help players get their hands on bonuses but it also improves and adds more fun and excitement to the whole experience. Not only can players of tournaments win bonuses, but there are also other prizes up for grabs, including cash prizes, cars, gadgets and some even offer players trips and holidays!
As with all other online promotions, you can expect to see a number of terms and conditions attached. These can often include the number of tickets you need to buy, how to buy tickets etc. Some of these tournaments and missions are for VIP and high roller players only. As with all casino promotions, you should always see what terms and conditions are attached.
Unravelling the Bonus Terms and Conditions
As we have often stated, before you claim any of these casino bonuses, you need to completely understand the terms and conditions attached, as these are the main giveaway as to how good the bonus actually is. Here are some of the phrases you should look out for:
Wagering Requirements
The main and most important of all the terms and conditions attached to any casino bonus is the wagering requirements. This can be written in a number of ways including "35 x wagering applies. Bonus funds only." This means that it is only the bonus funds that are subject to 35x wagering requirements, the qualifying deposit isn't included. So, for example, you make a £20 deposit to claim a £2o bonus that states '35 x wagering applies. Bonus funds only.' In order to claim your bonus and winnings, you would need to wager 35 x £20 = £700 of your own funds before you can claim your winnings.
However, some maybe '35x wagering the total bonus and deposit'. So, for example, you choose this offer and deposit £20 to claim £20 deposit match bonus which states '35x wagering the total bonus and deposit' in order to withdraw winnings and bonus funds you would need to wager 35 x (£20 + £20) = £1,400, which is twice as much.
As you can see, at first glance the welcome bonus may seem the same as the first one 100% up to £100 bonus funds and are subject to 35x wagering requirements, the wagering requirement applies to deposit and bonus so you actually have to wager twice as much, making it twice as difficult.
The size of the wagering requirement varies a lot from site to site, casino to casino, with the standard wagering requirements being 35x wagering. If you find casino bonuses with lower wagering requirements then great. However, if they are much higher than 40x wagering requirements then we would suggest looking for an alternative unless you are a high roller and have plenty of funds at your disposal. Never claim any of the casino bonuses on offer unless you know what the wagering requirements are whether they include bonus only or bonus and deposit.
It's also worth remembering that wagering requirements can be met with real cash only. Bonus funds do not count towards wagering requirements.
Minimum Deposit
Most casino bonuses will come with a minimum deposit amount before you can claim the offer. Often it will state 'Min deposit £10' which means that you have to make a qualifying minimum deposit of £10 to claim a bonus. However, if it's a match bonus, then it's important to remember that you will only get the same bonus as your deposit. If your bonus is 100% up £100 - min deposit £10, then if you do make the minimum deposit of £10, you will only get a £10 bonus. In order to claim the full £100 bonus, you will need to deposit £100. Usually £10 is standard, although some are higher and could be £20.
Max Bonus Bet
This is the amount of money you can spend on one single bet with your bonus funds. If you claim a £100 bonus, then at most casinos, you cannot put £100 on one single bet, the bonus needs to be split down into smaller bets. So, for example, if you claim a £100 bonus with terms and conditions that state 'min deposit £20. Max bonus bet using bonus £5' then, no matter what casino game you play, the biggest bet you can make at one time is £5. You can't go to a roulette table and put your whole £100 deposit bonus on black or red.
Bonus Spins on Selected Games
Many online casinos will offer bonus spins or extra spins as a part of their welcome bonus. However, you will find that often they will offer these bonus spins on selected games only. You cannot use these bonus spins on whatever games you want to. Often, the selected game or games will be mentioned in the small print. So, terms may say '100 bonus spins on selected games. Selected games include Book of Dead, Starburst and Gonzo's Quest' which means that you can only play these bonus spins on those games.
Also, bonus spins come with a certain value. Many are worth £0.10 which is standard. Any bonus spins worth more than that is great value and definitely worth taking up. Remember there is often a wagering requirement attached to bonus spins winnings and winnings are often capped at a set value.
Time Limits
All casino bonuses and bonus spins come with a time limit attached. Often, you will find bonus terms and conditions that state 'bonus spins must be used within 72 hours. Bonus funds must be used within 14 days.' This is pretty standard and it means that as soon as the bonus spins are credited to your account, you will have 72 hours to use them before they are invalidated. However, with the bonus valid for 14 days, then you have 2 weeks in which to spend your bonus funds and fulfil your wagering requirements. If you don't use the bonus funds and fulfil the wagering requirements during this time, then you will lose your bonus funds and all the winnings from the bonus.
Payment Exclusions Apply
Often a welcome bonus comes with payment method exclusions attached. This means that if you make your first deposit using a certain banking method, then you will not qualify for the welcome bonus or casino bonuses. Generally, this only applies to eWallets such as Neteller and Skrill - although sometimes PayPal is excluded. This is to prevent casino bonus fraud. If you use Neteller, Skrill and PayPal to make your casino deposits, then it is worth checking that these methods can be used to claim your casino bonuses.
The Game Contribution Percentage
Again, this is all to do with wagering requirements - which all casino bonus terms and conditions come back to. When you claim a bonus and accept the wagering requirements, then you will find that there is a game contribution percentage that apples (GCP) also known as game weighting. This means that not all games contribute equally to the wagering requirements. Normally, most slots contribute 100% to the wagering requirements, whereas table games and casino games such as roulette and blackjack may contribute 10% to wagering requirements. So, if a casino states that '40 x wagering applies' and it is attached to the bonus only, then should you claim a £50 bonus, then the wagering requirements would be 40 x £50 = £2,000.
Because slots have a 100 percentage GCP, then if you play on slots, then you will only need to spend £2,000 in real money to fulfil the wagering requirements.
However, if you were to play on blackjack and roulette, then because they only contribute 10% to wagering requirements, you would need to spend £2,000 x 10 (£20,000) of your own funds to fulfil the wagering requirement. This is something that you will need to take into account if you are a table game player. Always check the game weighting contribution first alongside the wagering requirements, so you know exactly what you need to spend in order to fulfil your wagering requirements and avoid confusion and disappointment.
Casino Bonuses FAQs
Which Type of Casino Bonus is Usually the Biggest?
Welcome bonus and deposit match casino bonuses are usually the biggest and best casino offers. With a welcome bonus, you can often claim anything from £100 all the way up to £1,500 and anything in between. However, this doesn't mean it is the best. Generally, the huge welcome bonus is really only suitable for a high roller due to the wagering requirements attached. If you claim £1,500 bonus with 35-times wagering, then in order to get anything back out, you would need to spend £52,500!
How Quickly Can I Withdraw My Casino Bonus?
Withdrawing casino bonuses and any winnings that come from casino bonuses isn't as simple as that. Firstly, before you think of withdrawing, you need to consider wagering requirements. These need to be met within a set time limit or you lose the casino bonus and winnings. Should you meet your wagering requirement then you can withdraw. This can take anywhere between 1-7 days depending on your withdrawal method and casino. You may also need to go through KYC checks which can add a day or two to the withdrawal process.
How Many Types of Casino Bonuses are There?
There are lots of different casino bonuses! Obviously, there are different welcome bonus options, including deposit match, bonus spins or a mix of the two. There are no deposit casino bonuses, wagering free bonuses, cashback bonuses, high roller bonuses, reload bonuses, missions, tournaments and cash drops.
How Can I Fulfil a Wagering Requirement?
Imagine you claim a £100 bonus with a 35-times wagering requirement. You choose to play on slots, and all the games contribute 100% to your wagering requirement. The casino is giving you 14 days to meet the wagering requirement and there is a max bet £5. In order to meet your wagering requirement, you will need to play £3,500 on those slots with your own funds in 14 days before you can withdraw any bonus funds or winnings.
How Do Casino Bonuses work?
Casino bonuses are ultimately designed to attract and retain customers. To start with, an online casino will offer a welcome bonus for new players looking to sign up and make their first deposit. This welcome bonus will usually be a match deposit bonus, bonus spins or a match deposit bonus with extra spins on top. Once this has been claimed, loyal and existing customers can expect ongoing promotions such as loyalty rewards, free spins and bonus spins, reload bonuses, cashback offers and more. At most casinos, the welcome bonus is just the start!
How Do I Claim A Casino Bonus?
This varies from casino to casino, as all will have different t&cs attached. However, generally, you will need to make a minimum deposit (usually between £10 to £20) with specific payment methods. You may need to enter a promo code or bonus code. Before claiming any promotions, read through all the terms carefully.
