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 casinos 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:
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 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.
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.
Claiming a No Deposit Slots Bonus at Gamblizard
While it may seem daunting to new players, taking the leap and claiming a free slots welcome bonus with no deposit requirements is much easier than it looks. Most casinos have implemented a streamlined claiming process, making it easy for you to access your promotion.
One of the key steps we’ve highlighted which often goes overlooked is ‘read the T&Cs;’ we know they’re not the most interesting thing to read, but they contain key information about your bonus.
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.
When using your free online slots no deposit bonus, the choice of slots to play out there will make you dizzy as the best casinos offer thousands of different games. You could spend hours comparing them and still come out none the wiser.
To save you that headache, we’ve listed our top slots favourites to use with your bonus, which not coincidentally turn out to be also the best payout slots:

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.
