Popular online slots bonuses for players in the UK

All gambling sites and guides are 18+ only

Welcome bonuses can play a large part in enhancing your online casino journey, and for some they are a crucial factor in deciding which site to sign up with. As some popular slot sites vie for supremacy, they know attractive bonuses are important. These offers typically take the form of deposit match bonuses, granting you for example a generous 100% match up to £100. Some also offer bonus spins to use on handpicked slot titles. This provides an excellent opportunity to explore new games without tapping too much into your own initial funds.

However, caution is key when engaging with any bonus or offer. Prior to diving in, take a look at the attached terms and conditions to avoid any unwelcome surprises. Here are some important things to keep an eye out for when looking for exciting online slots bonuses.

Eligibility – Are you eligible for the bonus? Welcome offers are only for players registering at the casino for the first time. Some sites may also require you to enter a bonus code to claim the offer and/or they may require you to 'opt-in' to the offer when creating your account.

Game restrictions – Which games can you use the offer on? Look out for this particularly when it comes to bonus spin offers, as these are often tied to a specific slot title and cannot be redeemed on others.

Wagering requirements – How many times do you need to wager the bonus amount or the bonus plus deposit amount before you can withdraw any winnings? For example, if the bonus has a 30x wagering requirement and you receive a £100 bonus, you'll need to wager £3,000 (30 times £100) before you can cash out your winnings.

Game contribution – How much do different games contribute towards fulfilling the wagering requirements? For instance, slots typically contribute 100% but table games can contribute less.

Time limit – When do you need to use the bonus funds or spins by? Most welcome bonuses have a strict validity period in which the bonus must be used, if not it expires.

Deposit requirements - How much do you need to deposit before you can claim the bonus? Unless it is a no-deposit bonus (which is becoming increasingly rare), most offers will require you to deposit a minimum amount, typically between £10-£20.

Remember to gamble safely - Approaching bonuses carefully, tracking all deposited funds and time spent gaming, setting strict limits, and avoiding "reload" bonuses, can promote safer habits. Utilising available site tools to monitor your gameplay and opting into cooling off periods when needed can also be proactive steps to gamble in a controlled, responsible manner - which should remain the priority when engaging in any gaming activity.

Payment methods at the online slot sites

All gambling sites and guides are 18+ only

When it comes to online slots payouts and funding your account, having reliable and convenient payment methods should be non-negotiable. Fortunately, the slot sites we highlighted earlier offer a range of popular payment methods, whether you prefer the familiarity of card payments, the convenience of eWallets or the flexibility of mobile payment options.

Here are some of the most used payment methods for UK slots players:

Debit Cards

It's important to note that from 2021 UK players can no longer use credit cards for online gambling. However, debit cards like Mastercard or Visa are still allowed and are a simple and secure way to make a deposit to your slots account. For many online casinos the minimum deposit by debit card is £5.

eWallets

These are an increasingly popular payment method for online gambling and are essentially digital wallets that allow users to store, manage, and transfer funds electronically. Some advantages include the convenience and enhanced security they offer compared to some other payment methods. Popular eWallets used by UK players include PayPal, Skrill and Neteller.

Prepaid cards

Another great option offered by many of the popular slots sites are prepaid cards such as Paysafecard. One of the main advantages of prepaid cards is that they offer an extra layer of security and privacy since they are not directly linked to a bank account .

Mobile payments

Mobile payments typically offer convenience and seamless transactions, making them popular for users at online slot sites. Some examples include Boku and Apple Pay. Some advantages of using these methods include speed and ease of use, as there's no need to enter card details or personal information for each transaction.

Crypto

You may be hard pushed to find this method at many online slot sites, but some out there do offer it. One of the most well-known types of cryptocurrency is Bitcoin and an advantage of this is that it allows for swift transactions.

Bank transfer

Lastly, there's always online banking. One of the main benefits is that it's widely accepted and supported by most slot sites, making it reliable and accessible. Just be aware that this method may take longer than paying via an eWallet for example.

Recommended online slots games – high payouts

When looking for exciting slot games, an important thing to keep in mind is the RTP or Return to Player rate. An online casino will have an overall RTP, but individual games will also have one, so make sure you're aware of it.

RTP essentially refers to how much of the total bets paid into the slot, on average, will be returned in the form of winnings over time. Keep in mind that RTP is an average, so if the RTP is 95% it doesn't mean that you're guaranteed to get exactly 95% of your money back on every single gaming session.

Choosing a game with a higher RTP is often a good idea (the closer to 100% the better), because these games payout a larger proportion of the money staked on them when averaged out over time versus games with a lower RTP. Some payout online slots will have an RTP of higher than 96%.

Games are also audited by independent agencies such as to check that the RTP is accurate.

Here are 10 online casino slots with high RTPs:

• Goblin's Cave - 99.32% RTP - This treasure-themed slot from Playtech has one of the highest RTPs and is offered by many slot sites. It's a three-reel slot with three paylines.
• Ugga Bugga - 99.07% RTP - This is another three-reel slot from Playtech, but with a twist. Set in the jungle, it has 10 paylines and 23 possible winning combinations.
• Mega Joker - 99.00% RTP - A classic from NetEnt, with retro fruit machine symbols and a supermeter mode, which when activated offers higher stakes and a potentially bigger payout.
• Jackpot 6000 - 98.90% RTP - A real retro slot from NetEnt with three reels. It will likely appeal to people who want the nostalgia of a real pub fruit machine, but online.
• Blood Suckers - 98.00% RTP - A vampire-themed game from NetEnt with five reels and 25 paylines. The game also has some fun bonus features to look out for like the vampire-slaying bonus.
• Starmania - 97.87% RTP - This NextGen video slot has high-quality graphics and a bright theme. The five-reels, 10 paylines and special features make this an engaging game.
• Kings of Chicago - 97.80% RTP - Another from NetEnt and a video slot with an existing twist. It combines classic slots with a poker game.
• Devil's Delight - 97.60% RTP - This wickedly fun video slot from NetEnt is set in the fiery pits of hell. There are some great extra features such as wild symbols, free spins and the sin spins feature.
• Couch Potato - 97.43% RTP - This game comes from Microgaming and takes things back to basics with a simple three-reel, single-payline design with a traditional fruit machine theme.
• Alchemist's Lab - 97.32% RTP - Alchemist's Lab is a slot game developed by Playtech. It features a unique 3-reel, one-payline structure, and gives players the chance to enter the alluring world of alchemy.

High vs low volatility slots

The volatility of a slot is something important to keep in mind when deciding which game to play. It essentially refers to the degree of fluctuation in a slot game's winnings over time and the distribution of potential payouts associated with a specific game.

There are low, medium and high volatility slots.

In low volatility slots, players can expect to receive more frequent, albeit smaller, wins. These games typically have a higher hit frequency, meaning winning combinations appear more often. While the payouts may not be as substantial, low variance slots offer a relatively steady and consistent experience.

Medium variance slots strike a balance between low and high-variance games. Players can typically anticipate a mix of moderate and smaller wins, with occasional larger payouts. These slots aim to provide a balanced gaming experience, appealing to players who seek a combination of regular wins and the excitement of bigger rewards.

High variance slots are known for their infrequent but more significant payouts. Players might experience longer periods of play without winning, but when a winning combination occurs, it can lead to substantial rewards. High-variance slots are preferred by players who enjoy chasing the highest jackpot at online slots and can withstand the higher risk involved. As a general rule, slots with a higher progressive jackpot tend to have a higher level of variance.

How to play online slots

Getting started playing online slots is easy. Firstly, you need to ensure you pick a reputable and licensed operator. For players in Great Britain, the licence from the GC is the one to look out for. Online casinos need this licence to legitimately offer their services to players in Great Britain and all casinos mentioned in this article are GC licensed.

Once you've chosen a licensed casino, sign up by providing the required information. You'll likely need to provide your name, email address, and create a password. At some point, all casinos will require you to provide photo ID and/or proof of address, and if you wish to deposit over a certain threshold you may also be required to provide proof of earnings.

After creating an account, browse through the casino's collection of slot games. UK players have access to a diverse range of themes, features, and jackpot sizes, so pick the ones that pique your interest.

To play for real money, you'll need to fund your account. Slots sites typically have a choice of payment options, which can include debit cards, eWallets, bank transfers, or prepaid cards, amongst others. Make sure to check if any deposit bonuses or promotions are available for your chosen method of deposit.
