THE SLOT BUZZ GUIDE TO UK SLOT BONUSES

What is a Casino or Slot Bonus? 

Let’s start with the basics. An online casino slot bonus is a sum of money credited to a casino player’s account that can be used to play slot games. Sometimes it will be offered ‘for free’ on registration or after completing a specified action like wagering on a specific game, but usually it will be credited when a player makes a deposit into their casino account. The bonus is never ‘free’, withdrawable cash. It can only be used to play slot games. Its purpose is to give customers better value through more playing time.

Slot bonuses are a valuable marketing tool used by casino operators to entice new customers through their doors and to keep existing ones happy. The online gambling industry is extremely competitive, with hundreds of slot sites all vying for attention whilst offering the same licensed software and the same games. There is little to choose between them. The slot site bonus is a way to shout louder than the competition.

These offers come in many shapes and sizes, and there are always conditions. Bonus money can never be withdrawn initially, and sometimes not at all, and there will always be restrictions on how it can be spent, and what you can do with the winnings.

This guide is to help you to identify the different types of bonuses and to untangle some of those tricky terms and conditions. We hope this will allow you to get the most enjoyment and value from playing slots online.

How we review the best bonuses for slots players

The Slot Buzz reviews from the viewpoint of a player, we tell all and our goal is to keep our eye on the good in order to filter through the bad and the mad. The good part is also the most important, we only review UK Gambling Commission licensed casinos, being without the safety and protection of the UK gambling laws are both mad and bad.

We share the information and basics we use in our new online slot site reviews, online slot reviews, casino reviews, slot reviews and bonus reviews. We strongly believe the knowledge knowing what to look for in a bonus removes nasty surprises and places players in the best possible position to make decisions based on facts.

Finding the Best Site

First, we find the best UK online slots sites in terms of quality determined by the software developers and quantity hence the number of current games and the tempo at which new slots are added on a regular basis. As our Industry Buzz section indicates, our love for diversity matches that of the biggest slot enthusiasts in terms of video slots, classic slots, 3D slots, and progressive jackpots.

Only Bonus Funds Can Be This Exciting!

Online casinos in the UK that manages to impress our review experts via game diversity are guaranteed a longer stay as the bonus section is always the next point of interest. Bonus scrutinizing is a finicky business that requires meticulous examination of the terms and conditions. Our bonus reviews pay special attention to the terms and conditions that govern the way each bonus activates, works and dictates the steps necessary to cash out winnings.

Basic Bonus Terms and Conditions

The T&C of a bonus outline the rules part of the agreement between the bonus-accepting player and bonus-offering casino. It lists the actions you agree to should you interact with the casino website by signing up, claiming a no deposit bonus, free spins bonus, deposit bonus, welcome bonus or any other form of online casino bonuses.

The rules a new player or existing member agrees to are the most important part and therefore the main focus of any review. Only bonuses found fair and within the guidelines set by the UKGC pass to the next stage and if the T&C ticks all the boxes, you’ll find them at The Slot Buzz on the List of Best Slot Bonuses!

Bonus Rating at TheSlotBuzz

Bonus review ratings at TheSlotBuzz include what’s on offer, the number of bonus spins or free spins and the slot games or casino games on which these are valid. What’s important in slot bonuses is the procedures followed, the questions we answer include when are the spins credited, also how exactly is the bonus spins winnings credited. Plus the games bonus win cap, max bonus conversion and wagering requirements all add or subtract from the real value of the bonus on offer.

Identifying Bonus Purpose

For The Slot Buzz, the review process starts after identifying the purpose of the bonus and if it serves the intent via the most successful result. If the intention is a type of foot-in-the-door bonus, we hunt down the best no deposit bonus spins or no deposit bonus offers, review each and filter all via our comprising process to bring you the best no deposit bonuses.

Deposit Bonus Objective

The variety of deposit bonuses caters to both new player and casino member objectives. Casino deposit bonuses for new players include first deposit match bonuses, welcome packages, and first deposit bonus spins. The main goal of a first deposit bonus is to get off to a great start with a doubled bankroll and free spins.

Deposit bonuses for existing members include reload bonuses, free spin offers on new slot machines, online slots bonuses, cash back slots bonuses, and loyalty bonuses. The purpose of these bonuses is more focused on increasing your bankroll to extend the number of online casino games you play. It’s also a great way to prolong playing sessions, stretch your online slots budget, earn better rewards, and ultimately increase your chances of winning.

How to Choose the Best Casino Bonus to Play Slots

Choosing the best casino bonus to play slots depends on the outcome you wish to achieve via the additional bonus funds. A UKGC licensed online slot site offers online casino games created by software providers approved by the Gambling Commission of Great Britain tested and certified as fair and RNG.

Reading the terms and conditions remains the most important step since these are part of every step along with activation, use, and cashing out. It all starts by identifying the steps needed to activate the bonus. Generally, this includes registration, it could be an opt-in required bonus, followed by the minimum first deposit. Providing the required documentation is the last step before account activation, find more details in our Fair Play section.

Do check if any deposit methods are excluded from qualifying for the bonus, visit our Online Slots Payment Methods section for alternative, safe and secure options. The most popular payment methods used by UK players include debit cards, bank transfers, pre-paid vouchers such as PaysafeCard, bank transfers such as Trustly, and cryptocurrencies. The most popular deposit method remains e-wallets such as PayPal. Double-check the maximum bonus amount you can unlock and the number of spins credited.

If part of a welcome package, free spins might be credited across the first few days of membership. In most cases, these require daily login and each free spin bundle might only be valid for 24 hours. Let’s have a look at the best slot bonuses currently on offer at the top three online casinos before we discuss more terms and conditions.

PROS AND CONS OF CLAIMING AN ONLINE SLOTS BONUS

Pros

  • Best Casino Bonus increases Funds -The greatest and most exciting upside of any online casino bonus is the bonus spins or cash itself. Often the welcome bonus amount will match your first deposit, giving you double what you invested. This is fantastic since it provides you with greater leeway and allows you to upsize in bets, it allows you to take more risk and the higher the risk the greater the potential to profit.
  • Best UK Casino Free Spins Bonuses -The best UK slot bonuses available at most online casinos are the offers available to UK customers that require no investment on the part of the player. In most cases, these are generous once-off offers available to new players. The no-deposit slot game bonuses UK are rare with the number of free spins credited, directly to the qualifying games. Excitingly as it is, the eligible games include the best bonus slots packed with features to secure more chances of winning via an array of features, for example, the Book of Dead slot.
  • Online Casino Bonuses Reduce Risk -One of the top advantages of online casino bonuses and UK slots bonuses is the reduction of risk factors. Due to bonus activation via a low minimum deposit, casino bonuses are the perfect opportunity for casino players who wish to enjoy games without taking too much risk monetary risk. Free spin bonuses and other online casino bonus offers don't provide the same freedom as betting with cash deposited, yet it remains a safer option, even when full t&cs apply.
  • Get Familiar & Gain Experience with First Deposit Bonuses -First deposit bonuses provide new players with the perfect opportunity to test their luck on the best slots and other casino games and to determine whether the online casino is the right option for them. Even more, so is gaining experience in terms of different bonus terms and conditions to adapt bonus strategies accordingly. The Slot Buzz are well aware of the fact that bonuses can significantly impact any player's casino experience, which is why we guide you in finding great casinos offering attractive offers. Please play responsibly.

Cons

  • No Withdrawal of Winnings before fulfilling bonus requirements -A online casino deposit bonus is great, although it also comes with terms and conditions. One of the big challenges in an online casino bonus is the wagering requirements which require casino players to fulfil playthrough and other bonus requirements before winnings via a no deposit or deposit bonus can be withdrawn. Although it can be a bit disappointing when your first deposit bonus playing session results in a low or even worse, empty bankroll.
  • Restrictions on Games via bonus spins -Even with most bonuses unlocked via a minimum deposit the bonus funds are not cash funds and therefore can only be used to play eligible games. It is actually impossible to play any other games with spins credited directly to the casino's pre-selected slot game. At the same time, the max bonus betting limit applies and it's necessary to know how different game types contribute towards wagering.
  • Bonuses can be misleading -The one thing that never changes is that full t cs apply and in that the saying "the devil is in the detail" is more true than ever. It is possible to find a great bonus offering a hundred or more free bonus spins only to discover that the free bonus games are only valid for a few hours or bonus funds expire in a day or two. If you don't use all spins within the time the remaining bonus spins get removed. Read the full terms and conditions its the only way to avoid disappointment or regret later, since the full t&cs apply always.
  • First Deposit maximum withdrawal limits -Casino bonuses offer free play on qualifying games and the game's bonus winnings at most online casinos get credited as bonus credits. The max bonus conversion limit determines the highest amount of winnings that can be converted to real money. It indicates the maximum amount UK customers can withdraw from bonus wins after completing the wagering and other bonus requirements.

DIFFERENT TYPES OF ONLINE SLOTS BONUS

Deposit Slots Bonus

The deposit bonus is the most common type. It is there to entice you to make a deposit, either when you sign up, when your account balance is low, or when it has reached zero. Operators like these bonuses because they can accurately predict their bonus budget against a guaranteed deposit income.  The ratio of the bonus value to the deposit value will vary depending on the offer. Welcome bonuses are usually more generous than re-load bonuses for example, and some casinos are more generous than others.

Deposit Bonus Example – On condition of depositing X a player will receive Y (usually a percentage of X). A slot site might offer a 200% match bonus up to £100. This means that if you deposit £50, you’ll receive £100 in bonus funds (200% x £50).

HINT – When accepting a deposit bonus always look out for the minimum deposit required to receive the bonus, and the maximum bonus paid out. In the previous example, if the maximum bonus is £100, if you deposit more than £50 you will still receive only £100 bonus. And if the minimum deposit required to receive the bonus is £10, don’t expect anything if you only put in a fiver!

No Deposit Slot Bonus

Sometimes a casino will offer players a bonus without the condition of making a deposit first. This is a common incentive to entice new customers to sign up, but a No Deposit offer may also be used to entice players back when they haven’t played for a while, reward players for their loyalty, or as a good will gesture after a bad run of luck.

No Deposit Bonus Example – Some casinos are currently offering £10 free – no deposit needed – for new customers. To qualify for this bonus all you need to do is register with the site. £10 will automatically be credited to you.

HINT – Usually when you register you will also need to verify your identity by entering your credit or debit card details. Don’t be put off by this. You are not making a deposit. Some casinos use your bank card as a method of account verification and they want to make sure the address details you register your account under match those of your payment method.

You can check our list of Free £10 No Deposit Offers to find out where you can play for free without a deposit.

Free Spins Offers

Free Spins are free plays on a specified slot game at a nominated stake value. When you have free spins just log into your account and choose the correct game, then start playing. Free Spins bonuses are commonly used as part of a welcome package or as a promotional tool for existing players. They can be credited when a variety of triggers are met. These include registering at a site, making a deposit, or wagering a specified amount on a game.

Free Spins Example – A casino may offer 20 free spins on Starburst slot for all new customers when they register an account. This is a ‘no deposit’ offer so remember in this instance you would have to enter your credit or debit card details with the same address as your casino account first.

HINT – There are typically some important conditions to be aware of when accepting free spins:

  • Free Spins are often game-specific. That means they are only eligible to be played on the games specified by your casino. The most common game for Free Spins is Starburst by NetEnt.
  • Winnings from Free Spins are often credited as bonus funds. This means that they cannot be withdrawn until the wagering requirements have been met. You can read more about this here.
  • Winnings from Free Spins are also regularly capped at a specified amount in the terms and conditions of the offer.

Whilst these are common restrictions for Free Spins offers the market is changing. More on this further down the page.

Slot Site Welcome Bonus Package

Every single operator in the UK will be offering a slot welcome bonus for its new customers. That is a given. The bonus is an essential part of the casino’s message to slot players – ‘join our site and you will be generously rewarded’.

In the past decade hundreds, if not thousands, of slot sites have launched in the UK. There are far fewer casino software suppliers than there are sites, so it stands to reason that many operators share the same game catalogues. This makes it very hard to stand out. In this crowded marketplace alongside the brand name, the welcome bonus is what sets one site apart from the others. Just take a look at the slot bonus list on this page to see for yourself!

Some welcome bonuses will be a one deposit deal, with an X for Y condition. Other slot welcome bonuses are delivered as packages, with a collection of deposit bonuses often accompanied by free spins. Usually, the package will consist of up to three deposit bonuses, each with different percentage matches, and minimum and maximum bonus values.

Slot Site Welcome Bonus Package Example – Slots Million are currently offering new customers a combined welcome offer of 100% up to £100 and 100 Free Spins on various games on the first deposit made. You can read more in our Slots Million review.

HINT – Casino operators will often total up the maximum value of each deposit bonus in the package and display this on the site and in advertisements to entice you in. If you do choose a slot site with one of these packages remember that the advertised value is the maximum you can receive and is conditional on depositing the top amount on each of your first eligible deposits.

Cashback Slots Bonuses

A cashback bonus is a common way for a casino to reward players for their loyalty. It can also be used to pay back players when they have a bad run of luck.

Here’s how it works. After a player has wagered on the required games and during a specified time period, the cashback value is calculated as a percentage of wagers – wins. The net result is the player’s overall loss.

Cashback Bonus Example – During a 25% cashback promotion, if a player wagers £1,000 and wins £500, then their losses are £500 and they get £125 cashback (25%x £500).

HINT – Cashback is sometimes credited as bonus money too, in which case it will have its own wagering requirements. Check the promotion terms and conditions to be clear.

Other Slots Promotions and Bonuses

There are plenty of other opportunities to earn slots bonuses and other prizes when you play at online casinos. Here are some of them:

  • Prize Draws – casino operators will often run prize draws as an alternative to regular bonuses. The conditions for entry will vary but usually require a player to deposit, wager, log-in, and play different games during the competition period in order to earn entries into the draw. Prizes may be anything from Free Spins and Bonus Money to iPads, Mobile Phones, or even cars or Holidays.
  • Tournaments – slot tournaments, or battles as they are sometimes known, are popular amongst slot players. They can be quick-fire – maybe just 30 minutes – and work like poker tournaments, or last longer – sometimes up to a week. Typically you can win bonuses, free spins and non-cash prizes. Find out more in our guide to online slot tournaments.

UNDERSTANDING SLOT BONUS TERMS AND CONDITIONS 

An online slot site bonus will always come with terms and conditions that include restrictions on how, when and where it can be spent. Here are the important ones to look out for.

1. Wagering Requirements (WR)

The first thing to remember is that your bonus is not free, withdrawable cash. It is given to you by the casino to give you more playing time, to explore the games and get better value for your deposit. And it’s not just withdrawals of bonus money that are restricted, it’s also withdrawals of any winnings generated by the bonus money too.

This is to protect the casino. Most slot games have a Return to Player (RTP) of around 95%. That means for every £100 wagered, on average £95 will be paid out to the player as winnings. If players could keep 95% of every bonus paid out to them by an online casino, the industry wouldn’t last very long! So, wagering requirements make the player wager their bonus funds over and over to reduce the risk of that player walking away with cash in their pocket.

Wagering Requirements are relative to either the value of the bonus, or the bonus AND the deposit. A typical wagering requirement might be 30x bonus. Remember, If the WR is 30x bonus AND deposit, the total WR is much more than it would be if it was just related to the bonus.

Wagering Requirements Example – If a casino gives a bonus of 100% match on a deposit of £50 and the WR is 30x the bonus, then the player must wager £1,500 (30x £50) before they can make a withdrawal.

Bonus Balance And Real Money Balance – Once you have made your deposit your account will display two balances: a bonus balance, and a real money balance. You will always play with your real money balance first before you play with your bonus balance.

Your bonus balance includes the bonus funds AND any winnings generated by those bonus funds. When you have met the wagering requirements, then your bonus funds will be transferred into your real money balance and you can make a withdrawal.

HINT – some bonuses are non-withdrawable (‘sticky’ or ‘non-redeemable’). These can never be transferred to your real money balance, although of course, any winnings from them can. Always check your terms and conditions to find out if your bonus is redeemable.

Wagering Requirements – When you are fulfilling your wagering requirements you should also be aware that not all games are equal! Some will count more towards your wagering requirements than others.

As a rule, slot games generally count 100%, whilst table games count much less – sometimes 10%, sometimes not at all. This is due to the varying RTP of casino games. You will have to wager 10x as much on a game with a 10% game weighting than on a game with a 100% game weighting.

You should always check your casino terms and conditions to understand the game weightings rules.

HINT – Bonus money is rarely eligible to use to play for Progressive Jackpots. This should be specified in the terms of the bonus. You may also be able to play the Progressive Jackpot game, but not be eligible for the top prize itself.

Your Deposit Is Locked In – It is also true that in most cases once you have deposited and received a bonus you cannot make a withdrawal of your deposit money until you have met all the wagering conditions of the bonus. If you do decide to withdraw before this time you will forefeit your bonus and any associated winnings.

Withdrawal or Winning Limits – Many online slot bonuses have withdrawal limits associated with them which basically define how much you can win with your bonus. This is almost always the case with no deposit bonuses. The limits are usually set at anything from £100 and upwards. Always check the terms and conditions to find out what the withdrawal restrictions are.

2. Slot Bonus Expiry

There are two types of expiry related to a new slot bonus.

Firstly, casino operators will often make a bonus available for a limited time, like 30 days from registration. This is because your casino will want you to deposit as soon after sign up as possible.

Secondly, once your bonus has been credited to your account it will normally have an expiry date – usually somewhere between 7 days and 30 days. This means that you must meet the wagering requirements for your bonus in the expiry time or you will forefeit your bonus.

These restrictions are implemented by a casino to push you to spend your bonus and to help them to keep their business clean. Operators do not like hundreds of accounts with unused bonus money in them.

Whilst this is fair play, always consider how much you want to spend and how much time you are happy spending that money in. Don’t be forced into depositing more than you can afford, or be pushed into wagering your funds aggressively. 14 days or more is a reasonable expiry limit. 3 to 5 days is not!

3. Maximum Bets With Bonus Money

Due to all the excitement that is part of claiming a bonus, it’s possible to miss some of the terms and conditions. Should you fail to comply with any of the rules there is a chance that the winnings you generated via the bonus might be cancelled. The max bonus bet rule overrides the maximum betting limits in games and is normally set at £5, although it varies from one casino to another and it can be higher in bonuses for high rollers.

The maximum bets with bonus money rules indicate the highest amount you can bet while playing with bonus funds. Breaking the rule by wagering a higher amount may result in the cancellation of the bonus and winnings accumulated via bonus funds.

4. Promo Codes for Bonuses

Several online casinos and especially new slot sites offer a variety of different bonus structures and promotions to cater to individual preferences. While some players love bonus spins, others prefer bonus funds, and for many, a combination of the two is the ultimate bonus package. Promo codes make it easy to claim the bonus of your choice when you deposit by entering the deposit casino bonus code, no deposit bonus code, free spins bonus code, or freeplay bonus code. Promo codes confirm your choice and ensure the casino awards the correct bonus.

5. Game Weighting

Game weighting is the wagering weight of different types of games, not all games contribute equally towards wagering requirements. It could vary from one slot site to the next, although in most cases online slots contribute 100%, although slots with high RTPs could be on the list of games excluded from wagering, which includes progressive jackpot games. In such case, the game weighting on slots is 100%, while it can differ for other permitted games, for example from 2% for blackjack, or 5% for video poker, to 25% for poker and up to 100% for keno.

6. Excluded Slot Games

The bonus terms and conditions section includes a list of excluded slot games, these are slots with high volatility and RTP percentages that are excluded from bonus wagering. The list varies depending on the games available at the casino, although the usual suspects include 1429 Uncharted Seas, Dr Jekyll & Mr Hyde, Forsaken Kingdom, The Wish Master, Castle Builder, Bloodsuckers, Mega Joker, Kings of Chicago and more.

WHAT MAKES A GOOD SLOT BONUS? HERE IS A 5 POINT CHECKLIST

Now you know all about slot bonuses, here’s a quick 5-point checklist to help you choose the right one for you.

1. What Is The Minimum Deposit? ☝️

Don’t deposit more than you would normally or had planned to unless you are completely comfortable. Slot bonuses have a range of values to suit players. Pick the one that best suits your spending habits.

2. What Is The Percentage Match? 👍

Most welcome bonuses start with at least 100%, but you can pick up a lot more. If you can get a 200% Bonus (e.g. 200% up to £200) then the offer is looking good.

3. What Are the Wagering Requirements? 👉

Higher bonuses often have higher WR to give the casino more protection. If you can get a 35x WR on a 200% bonus of £200 it is worth taking. The magic combination is a high % with a low WR.

4. What Games Can You Play? 🤝

Always make sure the bonus is available on the games you like playing. Free spins will often be restricted to one game whereas bonus money will be available to play across many more games.

5. When Does the Bonus Expire? 🙌

How long do I get to play my bonus? Don’t be pushed into spending more than you normally would in a short period of time. Only ever spend what you are comfortable with.

Slots Bonuses for Mobile Players

One of the major shopping and entertainment changes over the past decade is the shift to digital, and the time consumers and players spend on their mobile devices continue to increase. It creates an incredible opportunity for online casinos to be closer to the mobile audience they serve. It’s a mobile player market right now since thousands of online slot sites compete by spending tons to attract new players and retain existing members.

The main focus however is on converting online players to multiple platform players, which means mobile-exclusive bonuses. What is super exciting about this is that the bonuses are not only limited to players registering a new account via mobile devices but also offered to existing members playing for the first time via their mobile devices.

RECENT CHANGES IN ONLINE SLOT PROMOTIONS

Finally, a word on changes in the casino industry.

In 2017 online casino operators came under increasing pressure from the UK Gambling Commission to be more transparent when promoting bonus offers for new and regular customers on their sites. This followed a series of high-profile cases in which customers complained of misleading promotions.

As a result, some operators have simplified their promotions, even removing wagering requirements and maximum wins entirely. You will now often see the term Free Spins replaced with Extra Spins or Fair Spins, and promotions including the words, ‘no wagering requirements’ and ‘no winning restrictions’.

This is good news for the customer as operators are removing some of the more knotty and opaque terms and conditions to make things easier to understand.

Above all, remember that you are never forced to take an online slot site bonus. You can always choose not to opt-in, or even contact the casino and say that you don’t wish to receive a bonus when you make a deposit. They always want your custom and will comply with your request.

Now, enjoy your favourite bonus offer from any one of the renowned slot sites here at The Slot Buzz… Have fun!

Frequently Asked Questions

Why do Casino Bonus T&C include a Max Bonus Rule?

The max bonus bet rule only applies to bonus play and should players make larger bets, the payouts are also higher. The rule is fair since bonus funds provide you with more money to play, which could easily lead to larger wins. The casino adds the rules to ensure they can payout all the bonus wins. At the same time, the max bet rule also comes into play in completing the bonus wagering requirements. It prevents players from getting too caught up in completing the requirements and ending up spending more than their budget. It's preventing overspending and contributes to responsible gambling.

Bonus Spins, What are Considered Reasonable Wagering Requirements?

Wagering requirements hugely vary from one online casino to another although reasonable wagering also depends on whether it's applied to bonus or wins from free spins or the bonus and deposit.
If applied to bonus or wins from free spins only, wagering requirements of 35x or less is great. Applied only to bonus funds 40x up to 50x is decent, while higher up to 70x is luckily almost unheard of. If the above requirements are also applied to the deposit it completely changes and anything above 40x is really high, which is why it is always best to join a UK casino that only applies wagering requirements to bonus funds.

Free Spins, Why Split Across Several Days?

The best online casino welcome packages combine several match deposit bonuses with a huge helping of free spins. A large number of free spins is added across several days, for example, 100 free spins are normally added in increments of 20 per day across the first five days. The reason is to ensure the new player has five days of free spin excitement to look forward to, and it gets the new member into the habit of visiting the casino regularly.

How do I Claim a Bonus from an Online Casino?

The process of claiming an online casino may vary slightly since every casino is different and so is each bonus. The best way to locate a UKGC-licensed casino is to visit The Slot Buzz Online Casinos UK section or the New Slot Sites 2022 section.
Find the casino that best suits your preferences and playing style, and press the red "play slots" bar, which instantly links you to the casino and the current promotion. Read the terms and conditions, register, activate the bonus via the minimum deposit or more and start enjoying all the benefits of membership with a welcome bonus boosted bankroll.
