We don't roll the dice on casino bonuses
Every recommendation on Bookies.com is earned and tested by real experts across five weighted pillars before we put our name behind it.
What Makes a Top Slots Sign Up Bonus?
Not all slots sign up bonus offers are the same, so there are a few key elements to look out for when you’re choosing a promo.
Bonus Size
The first thing to check is the size of the bonus. Unfortunately, there are a few online gaming sites that give out very small offers, for example £10 in casino credits when you deposit, but the best slots sign up bonuses are worth £100 or more.
Wagering Requirements
The wagering requirements are also really important, because sometimes a smaller online casino bonus with lower wagering actually works out better than what might look like a more generous offer, but with higher wagering requirements. Luckily here in the UK, the max wagering is 10x the bonus amount.
Deposit Size
The best slot sign up bonus offers don’t require a huge first deposit to claim at £10 deposit casinos. You’ll either be able to get them with a low deposit of just £10 or more, or they’ll be completely free, as soon as you sign up. You’ll want to claim the best online casino promotions that have a generous max win amount, for example 5x or 10x the bonus amount. But be aware that some sites restrict you to an amount equal to your lifetime deposits.
Game Restrictions
Most casinos have certain restrictions on the free sign up bonus slots that you can actually play with the offer. We prefer promos that give you the option to use on a few different games, but failing that we tend to look for online casino promotions valid on top titles like Starburst and Gates of Olympus.
Time Limits
Finally, it’s worth checking how long you have to use the bonus. Sign up bonus slots offers might only be valid for a day or a week, so we’d recommend looking for promos with longer timeframes. Some will be 14 or even as long as 30 days.

Why Play Slots?
Well, where do we start? There are so many reasons you might want to play slot games, and using an online slots sign up bonus is the perfect way to try them without breaking the bank.
Slots are fun because they come with all sorts of different themes and features. Whether you prefer old-fashioned, retro slots, games themed around cuddly animals or big adventures, there’s something exciting waiting for you.
The special features like bonus rounds, Megaways, multipliers and cascades make the gameplay experience even more thrilling. And, of course, don’t forget that slots offer the potential for some pretty big wins - there are even progressive jackpots that can pay out millions of pounds on a single spin. Find the best payout slots in the UK here.
Remember, slot games don’t involve any skill, as they’re purely based on luck. This means there’s never a guarantee that you’ll win, so it’s important to play responsibly. You should only ever play for fun, not with the expectation of winning and never chase losses or play for more than you can afford.
Top Games To Use Slots Sign Up Bonuses
If you’re claiming a free spins bonus, chances are you’ll need to use it on a certain game, but other types of slots bonus offers like deposit match promos and casino credits are more flexible.
If you’re looking for some inspiration, you might want to choose a game with a high Return to Player (RTP) percentage, as these tend to pay out more over a long period of time. Games with special features are also a good option, as they can be more entertaining and immersive than standard slots.
We’ve done a bit of research into some of the top casino games, and we’d recommend playing these online slots with sign up bonus offers.
Big Bass Splash
Pragmatic Play’s Big Bass Splash is so popular that there are now more than 30 spin-offs of the game! It’s a highly-volatile slot with 96.71% RTP and a max win of 5,000x, making it a great choice for any players with a casino sign up bonus slots offer.
The bonus round is what really makes Big Bass Splash stand out. Look out for the scatter symbols that trigger the free spins round with up to 20 bonus games - during free spins, the fisherman symbol collects real cash values from the fish money symbols. The bonus game also comes with modifiers like more wilds or extra fish symbols, plus there’s a respins feature. Big Bass Splash free spins are regular features in sign up bonuses.
Book of Dead
This Play’n GO casino title follows the adventurer Rich Wilde as he heads into a mysterious Egyptian temple, in search of the magical Book of Dead. The game features scatter symbols that open up the free spins round, as well as expanding wilds that could lead to bigger payouts during the bonus round.
The game has an above-average RTP of 96.21% and it’s highly volatile, making for exciting play. Book of Dead comes with a gamble feature, which gives you the chance to try to increase your payout after each winning spin. This could see you bagging extra cash and making your slots sign up bonus go even further, particularly if you have Book of Dead free spins.

Fishin’ Frenzy
If you’re a fan of fishy games, this is definitely one of the best sign up bonus slots out there. Fishin’ Frenzy is quite a simple slot, played on a 5x3 grid with 10 paylines. The RTP is slightly above average at 96.12%, and the volatility is low to medium leading to more frequent, smaller wins (good news as you won’t use up your bonus too quickly).
The Fishin’ Frenzy free spins round sees the fisherman wild collect money symbols with multipliers of up to 500x - it’s similar to Big Bass Splash, but with a slightly more retro feel.
Eye Of Horus
Can’t get enough of Egyptian-themed games? Eye of Horus is a great option for using your slots sign up bonus. While the design of the game is quite simple (5x3 grid with 10 paylines), the theme is strong, featuring Egyptian gods as the high-paying symbols.
The game comes with an RTP of 96.31%, and the fact that it’s highly volatile means wins tend to be a little bigger than average, so you might just be in for a nice payout with your bonus. Get at least three scatter symbols and you’ll bag 12 Eye Of Horus free spins, which come with symbol upgrades for bigger potential wins.
Gates Of Olympus
For the theme alone, Gates of Olympus bags a spot as one of our best sign up bonus slots. Set in Zeus’ temple, this dramatic game features HD graphics and lots of animations to set the scene.
You’ll get payouts for landing enough of the same symbols anywhere on the grid, while the tumble feature removes winning symbols to give you extra chances to win - great for extending your slots sign up bonus.
You might even get lucky enough to bag a multiplier of up to 500x! Gates of Olympus is a highly volatile slot, and the RTP is above average at 96.50%. You should always jump on any Gates of Olympus free spins offers.
My favourite slot game has to be Bonanza. It’s the original Megaways slot, so it’s extra thrilling because you never know how many symbols are going to land on each reel when you spin. The bonus round is particularly exciting, because the multipliers are sticky the whole way through.
What Different Slots Sign Up Bonuses Are There?
By now you probably know most casinos in the UK have a slots sign up bonus for brand new players, but every site offers something a little different.
While a 100% deposit match up to £100 is pretty standard, some casinos offer free spins, cashback or - best of all - a no deposit bonus, so that you can play without spending a penny. These are some of the top slots sign up bonuses to look out for.
Matched Deposit Welcome Bonus
A deposit match is one of the best slots sign up offers you could hope for. Matched bonuses add extra money to your deposit amount. For example, you could get a 100% match up to £100, so you’ll have up to £200 to play with.
A deposit match bonus is versatile, as it’s generally available on a range of games across the site, rather than a selection of just a few.
No Wagering Slots Bonus
Most slots sign up offers come with wagering requirements (set at a maximum of 10x in the UK), so you’ll need to play through the bonus amount or free spins winnings a certain number of times before you can withdraw.
But no wagering bonuses winnings paid in real cash is commonplace, so you can withdraw immediately. Low wagering casino bonuses are hard to find, but they’re worth looking for, as they’re really risk-free.

Cashback Bonuses
Cashback is a way to reduce the risk of losing real money, as you’ll be able to claim some of your net losses back, usually in the form of a cashback casino bonus. An online gambling site might hand out cashback as part of a sign up slots bonus, or you could get it as often as every week if you’re a regular player.
Be sure to check which games are included. For example, you might not get cashback on progressive jackpots or very high RTP games.
Reload Bonuses
While new players can often look forward to generous deposit match offers, regulars can claim casino reload bonuses that tend to be slightly smaller, but they’re still a great way to boost your deposit. Keep an eye on the casino promotions section at your online casino and you might just bag a reload slots bonus of up to 25%. Reloads are just like deposit match offers, in that they can be used on lots of different games.
Free Spins
New slot sites with a free sign up bonus often hand out extra spins, and if you’re really lucky, you won’t even have to make a deposit to get them. Deposit free spins are usually valid on a particular game (or a selection of a few games), with Starburst, Book of Dead and Big Bass Splash being amongst the most popular.
While most free spins bonuses come with wagering requirements, some even award winnings as real cash that you can withdraw immediately.

The next thing to do is actually claim your slots free sign up bonus. Depending on the casino, you might get it as soon as you sign up, or you might need to make a deposit (usually around £10) to get the free spins or deposit match.
