What is a No Deposit Slots Bonus?

A no deposit slots bonus is made up of two key components: you do not need to make a real money deposit to claim it, and it can only be used on slot games. The lack of a required deposit makes this bonus perfect for new players, allowing them to graduate from playing for fun to learning how to play slot machines for real money.

Some players may find these promotions restrictive, as they can only be used for online slot games. That being said, they provide a great opportunity to players who want to try slot games specifically but don’t want to risk their bankroll.

Pros and Cons of Free Slots Bonuses

Before making a financial decision at an online casino, such as claiming a casino bonus, it’s smart to weigh up its pros and cons. We’re here to provide you with all the information you need to consider everything carefully; we’re not scared to share the negatives of these promotions and we won’t sugarcoat the truth. To that end, here are the key advantages and disadvantages of free slot promotions.

• Pros
• You can try new slot sites with no deposit requirements.
• Beginners can try real money gaming in a lower-risk environment.
• You can build confidence and test strategies before risking your own money.
• They offer the chance to learn a slot’s features.

• Cons
• Some bonuses have low maximum wins, limiting the value of your rewards.
• These promotions do not let you play table games or live dealer games.
• Many offers have inflated wagering requirements, making it hard to convert your rewards to real money.
• Free spins promotions are limited to specific games, making it hard to experiment.

If you’ve decided that you want to try a no deposit slots online promotion, the next step is to look at our recommendations. But first, allow us to give you an insight into the features we value the most when picking bonuses for you.

How We Rate Casinos Offering Free Slots No Deposit Promotions

Creating a list of new no deposit casino recommendations is an arduous process that involves our entire team of casino experts. We analyse and review dozens of different casinos, gathering data on the features that the average UK player wants to know about. To make a consistent data set, our experts work from a list of review criteria:

Player Security

Safety should always be your number one priority when choosing a new slots no deposit casino. To make your life easier, we guarantee that all Gamblizard’s recommended casinos are fully licensed by well-known gambling authorities. Our team checks each site for a valid licence, up-to-date security features, and the latest player safety tools, making sure you have a safe and fair place to gamble online.

Bonus T&Cs

We know that most of our readers won’t even glance at the T&Cs of an offer before signing up, so we take on that burden for you. Our experts look through the terms of each promotion, showcasing the sites that offer clear and fair conditions and highlighting those that are unreasonable.

On-the-go Gaming

According to the UKGC, around 50% of UK punters use their phones to gamble online, that’s why mobile compatibility is a key part of any review process conducted by our experts. We use multiple devices to test how easy it is to play casino games for mobile players. Sites that offer a mobile slots no deposit bonus are given extra marks.

Cashout Process

Once you’ve used your slots bonus with no deposit, we know that your next priority is getting access to your winnings. Our team tests the withdrawal procedure using several payment methods, reporting back on the ease of the process, the average withdrawal time, and any payment fees they had to pay.

User Interface

The user interface is the kind of thing that’s doing its job if you don’t notice it at all. The best-designed sites offer no resistance while browsing them; everything is readily available and clearly labelled, making it easy to find what you need. We highlight the sites that offer the most user-friendly interfaces for both mobile phone slots and PC games.

When creating lists of the best slot sites with no deposit obligations, our experts consider all of these factors. Only the sites that excel in multiple areas become a part of our recommendations.

Best UK Casinos Offering a Free Slot Bonus Without Deposit

Researching and rating each casino in Great Britain with a free slots welcome bonus is only half the battle. Once we’ve gathered the data, it’s time for our experts to put their heads together and create a definitive list of the best picks from all UK casino sites that have new online slots with no deposit needed.

Each of the sites listed below offers a generous welcome package, as well as other features, such as stacked game libraries, multiple banking options, and a helpful support team:

*Bonus is cleared by earning 2 redemption points per £1; the bet required to earn a redemption point varies from game to game.

Varieties of UK Slots No Deposit Bonus Offers

When discussing bonuses that let you play online slots with no deposit needed, we discuss them in two ways: how you claim them and the rewards they offer. Both of these factors are independent of one another, meaning that the way you claim your no deposit welcome bonus does not impact the rewards you receive. We think it’s important to highlight the distinctions between several no deposit bonus varieties so that you are realistic about the potential rewards you can claim.

No Deposit Slots Welcome Bonus

During our research, we found that the vast majority of no money bonuses are aimed at a new customer. To claim a sign up bonus with no deposit required, you must create a new account at the casino and complete the site’s verification requirements. The exact method by which you verify your account varies from site to site, so we recommend getting familiar with all of the most popular authentication methods:

Mobile Verification

A widely used method of account authentication at GB casinos is mobile verification. During the account creation process, you’ll be asked to enter a valid mobile number; the casino will make an automated call to this number, relaying a 4- to 6-digit code. Once you receive this code, enter it and confirm your account verification to receive your rewards.

SMS Verification

Another procedure that requires you to enter a valid mobile number is SMS verification. Many players prefer this method as the code is sent over text rather than via a robocall, making it the more accessible option. Once you have received the text, simply enter the 4–6 digit code in the space provided and your rewards will be automatically credited to your account.

Debit Card Verification

A rare, but still present request at some UK casinos is that of a valid debit card. Casinos will ask for this as proof that you have the means to make a deposit once you have used your bonus. Don’t worry; the casino will not take any unapproved payment.

Once your account is up and running, you’ll be asked to enter your card details into the casino’s secure portal. As soon as the site confirms that your details are valid, you’ll receive your casino rewards.

Email Verification

Arguably the easiest and most common method of account verification requested by UK casinos is done via email. Once you’ve created your account, the site will send you an authentication link to the email you used during the sign up process. To verify your account, all you have to do is click this link.

That’s all there is to it. After following the link, you’ll see a message thanking you for verifying your account. As soon as this has been confirmed, the site will release your free casino slots bonus.

Promo Codes

While setting up your casino account, you may see a dedicated space for a promo code. Many of the best sign up offers require one of these no deposit bonus codes to be entered to trigger the promotion; if it is not, you won’t receive your rewards even if you follow the rest of the requirements.

We’ve found that promo codes are often used in conjunction with other authentication methods, so make sure you complete these requirements to collect your bonus.

No Deposit Bonus Funds for Slots

A relatively new addition to the slot bonus roster. These promotions offer free credit that can only be used on a site’s slot games. These bonuses are less restrictive than free spins promotions, giving you the freedom to try new no deposit slots.

£5 Free Slots

The lowest-value offer is also the most commonly found at casinos in the United Kingdom. A £5 free spins on registration no deposit promotion typically offers the most player-friendly T&Cs, making it easier to convert your rewards.

£10 No Deposit Slot Bonus

Offering increased rewards, the 10 pounds free no deposit bonus gives you a healthy amount of casino credits to play with. Despite the higher value, the £10 no deposit slots promotions usually have reasonable terms and conditions.

£15 Free Slot Games

A £15 free no deposit bonus gives you great value for money, allowing you to try a variety of different real money slot games. Expect these promotions to have a low win cap and increased playthrough requirements.

£20 No Deposit Slots

The biggest bonus that you can find at UK casinos is the £20 free no deposit bonus. These promotions offer a significant amount of funds that you can use to try different slot games. However, they often have the most restrictive conditions, so expect high wagering requirements and short expiration dates.

No Wagering No Deposit Slot Games Bonuses

Probably the most valuable free no deposit slots bonus available at online casino sites in the United Kingdom is the no wagering offer. These promotions come with zero wagering requirements and are sometimes called ‘keep what you win’ bonuses.

For most promotions, the biggest hurdle to overcome when converting your rewards to real money is the playthrough requirements. These bonuses skip that step entirely, giving you immediate access to your winnings.

Due to the ease at which you can convert your funds to real money, these promotions are hard to find at UK casinos. They also offer lower-value rewards than traditional promotions; for example, the best slots welcome bonus with no wagering and no deposit requirements may offer 15 FS, while a 40x wagering bonus may offer 100 free slots rounds.

Free Spins Slots Bonuses

Considered the traditional iteration of this promotion, a slots free spins no deposit bonus allows you to play specific slot games for free. They’re by far the most common promotion available at zero deposit casinos, as they’re much easier for the casino to control.

Each spin will have a set value, typically £0.10, preventing you from making large wagers that could result in big wins. These promotions are also typically restricted to one or two no deposit slots games, limiting your potential options.

That being said, we’ve found that FS bonuses with no deposit on registration usually have reasonable T&Cs when compared to other slot promotions, making them a more appealing option. Before claiming your rewards, you’ll have to complete your casino’s sign up and verification process, so we prepared a rough guide to help you with it.

Terms and Conditions of No Deposit Slots Bonuses

The T&Cs of your promotion outline the rules that you must follow while claiming and using your bonus. These rules can drastically alter the value of your rewards, turning what seemed like an appealing promotion into one that’s barely worth claiming.

If you’re unfamiliar with bonus terms and conditions, we’re here to help; our team have highlighted key clauses that you should always look for when claiming a promotion:

• Wagering Requirements – The wagering or playthrough requirements of your bonus outline how much you need to use it before you can withdraw your winnings. For example, let’s say you win £20 from your free spins; with 40x wagering requirements, you’ll need to play £800 worth of casino games before you can make a withdrawal.
• Contribution – An often ignored condition is the contribution rate of specific games. Some slots do not wholly contribute to your playthrough requirements, increasing the amount you have to play before making a withdrawal. Some contribute as little as 10%, effectively 10x-ing your requirements, so it pays to pick ones that fully contribute.
• Available Games – Many free spins promotions have limited availability. There will typically be one or two slot machines where you can use your spins, restricting your ability to use them.
• Win Cap – A common condition of a free slot games no deposit bonus is a win cap which limits the amount of real money you can earn from your rewards. Any casino credits that exceed this cap at the point of conversion will be removed from your account.
• Expiration – Once you receive your rewards, you’re on the clock. Each promotion has a set expiry date; you must fully use your rewards and clear all outstanding wagering requirements before this date or your bonus will be removed from your account.

Only once you’ve found a bonus that offers reasonable conditions across the board should you start to worry about the games you’re going to play.

Maximising Your No Deposit Slot Rewards

Our help doesn’t stop once you’ve claimed your online slots no deposit bonus; we’re here with you each step of the way to make sure you maximise your rewards. Many players don’t plan how they’re going to use their promotion, leading to inefficient gameplay and missed opportunities. If you want to make the most of your slots online no deposit bonus, follow our expert team’s helpful tips:

• Choose Low Wagering Bonuses – Your bonus planning should start before you’ve even claimed your first promotion; offers that have low wagering requirements are much easier to convert and should be prioritised when available.
• Decide What You Want – Before claiming your promotion, we recommend taking a step back and figuring out what you want from your bonus. Are you aiming to eke out every last bit of value, or do you want to gamble it up in hopes of a big win? Understanding your motive will help you get maximum enjoyment from your rewards.
• Play Appropriate Games – Once you’ve decided how to use your bonus, look for games that fit your M.O. Value players should focus on games with high RTP rates and low volatility that pay out frequently, while gamblers should play high variance games that offer the chance of a large win.
• Check Game Contribution – When clearing your wagering requirements, take the time to look at the contribution rates of different games. Ideally, you want to play ones that offer 100%, as these keep your playthrough requirements to a minimum.
