The Best New Online Slots in the UK for 2021

1. Rhino Hold & Win — Best New Slot Overall

Release Date: July 10, 2021

Studio: Booming Games

Casino: PlayOjo

Cool “Major Free Spins” feature

Offers lots of jackpot opportunities

High variance

If you love big swings, then Rhino Hold & Win from Booming Games is the title for you. It’s loaded with jackpot opportunities, and there’s a “Major Free Spins” feature that gives you up to 8 free games every time it’s triggered.

While you can make a lot of money in a hurry at this game, it’s also quite volatile, as it only has a 95.87% RTP. 

You can find this game at PlayOjo, which is one of our favorite online casinos. It offers bonus money without wagering requirements, and you can withdraw as little or as much money as you like, whenever you like.

2. JurassicWorld Raptor Riches — Highest Hit Rate

Release Date: March 9, 2021

Studio: Fortune Factory Studios

Casino:

High hit rate of 44.45%

Fun themed option

Low max win of just 2,500x

96.02% RTP

Fans of themed games will love Jurassic World Raptor Riches, as it’s full of familiar faces (yes, including raptors) from the hit movie franchise. 

The game provides a steady dose of wins, as it has a hit rate of 44.45%, but it counterbalances all those victories with relatively low payouts. The most you can win here is 2,500x your bet.

This game is hosted by Casino.com, which is primarily known for its generous welcome bonus, which includes a healthy number of free spins.

Release Date: February 9, 2021

Studio: Green Jade Games

Immersive gaming experience

Can pay to activate free spins mode

Gameplay gets repetitive after awhile

96.27% RTP

Based on the children’s classic Alice in Wonderland, Cheeky Cheshire from Green Jade Games does everything it can to make you feel like you’ve fallen down that rabbit hole behind Alice. The graphics and soundtrack create an enchanting world that you’ll be happy to get lost in for hours at a time.

The free spins mode is a ton of fun, and you don’t have to wait around to activate it, as you can simply pay to skip right to it. However, while the regular gameplay mode is simple and easy to learn, it does get repetitive over time.

This slot is found at Magic Red, which prides itself on having quirky and offbeat titles like this.

Release Date: September 30, 2021

Studio: Blueprint Gaming

Creates movie-like experience

Lots of opportunities for free spins

Medium volatility

Payout percentage at 96%

Classic movie lovers will enjoy The Goonies Return from Blueprint Gaming. There are plenty of graphics and animations that give the whole thing a cinematic vibe that’s quite enjoyable.

You’ll still get all the perks of a slot machine, of course, including multiple bonus spins. However, the max bet is only at £500.

The Goonies Return is found at The Sun Vegas, which has a ton of other fun casino games in addition to slots.

5. Brides of Dracula Hold and Win — Best Mobile Gameplay

Release Date: July 10, 2021

Studio: iSoftBet

Casino: Mansion

Extremely interesting gameplay

Mobile-friendly design

Lacks a free spins feature

RTP is 95.5%

Made by iSoftBet, Brides of Dracula Hold and Win is a fun and engaging title under the most normal of circumstances. Once you trigger the bonus mode, though, all sorts of special features flood your screen. 

It’s just as fun playing mobile slots with this title as it is playing on a desktop, as it offers glitch-free play without sacrificing any features. What you will sacrifice, however, is a free spins option.

Mansion Casino is the best destination to play this title. And while you’re there you can also enjoy their excellent assortment of bonuses for both new and established players.

6. Well of Wilds Megaways — Best Free Spins Mode

Release Date: October 7, 2021

Studio: Red Tiger

Multipliers go up during free spins

Cascading reels mechanics leads to extended wins

No jackpots available

Red Tiger’s Well of Wilds Megaways is an Irish-themed title, so right away you know that they’re going to lean heavily into the “luck” factor. That’s especially true during free spins, as the multipliers can get as high as 40x, giving you the chance to earn a ton of bonus funds.

There isn’t a jackpot feature, but it does have an RTP of 95.67% and a cascading reels feature that can lead to indefinite wins (capped out at 10,500x) — not bad for a day’s work.

You can play Well of Wilds Megaways at Lucky Niki, a site that’s made a name for itself with its impressive daily deposit bonus.

7. Helios’ Fury — Best Bonus Rounds

Release Date: October 6, 2021

Studio: Relax Gaming

Staggering 50,000x max payout

Multiple bonus rounds

Not all features available for UK players

While it has a Greek theme that’s been done to death, you don’t play Helios’ Fury from Relax Gaming for the ambiance — you play it for the money. It offers plenty of that, as it has an incredible 50,000x max payout and multiple bonus rounds to keep the cash coming.

However, if you’re playing it from the UK, you’ll find that not all of the features are available to you.

Helios’ Fury is hosted at Jackpot Village, which, true to its name, is renowned for its bloated progressive jackpots.

8. Mental — Best Themed Slot

Release Date: August 31, 2021

Studio: Nolimit City

Intense horror theme

3 linked bonus rounds

Hard to follow

96.06% RTP

Mental from Nolimit City is the rare horror game that actually manages to be horrifying. The theme includes disturbing images of mental patients, organs, and more.

There are three potential bonus rounds, each of which can be linked to give you the potential to land a big score and earn bonus spins. However, all of the action can get a bit hard to follow, so sometimes it’s difficult to understand whether you earned any bonus funds.

The best place to give Mental a try is Leo Vegas, which offers a great combination of both new and classic slots.

— Best Progessive Slot

Release Date: August 30, 2021

Studio: Playtech

Four progressive jackpot options

96.35% RTP

Can win random cash prizes

Theme is nothing special

Norse marauders are popular fare for slot machines, and Playtech’s Vikings: Empire Treasures doesn’t really bring anything new to the table in that regard. 

Don’t let that trick you into giving up on the game, though. You can win random cash prizes during regular play, and there are four different progressive jackpots that will keep you coming back for more.

This game can be played at Slots Heaven, and while you’re there you can take advantage of their mystery bonus offers.

10. Piggy Bank Bills — Most Unique Gameplay

Release Date: September 27, 2021

Studio: Pragmatic Play

Fun and unique gameplay

Able to win 5,000x on a single spin

Can be hard to spot a winner

RTP is 96.5%

If you want something a little different from the traditional slots experience, Piggy Bank Bills from Pragmatic Play offers a unique slant that many players will find irresistible. It’s a double-edged sword, however, because it can be difficult to tell if you’ve won.

You won’t be complaining if you hit it big, though, and you can win up to 5,000x your max bet on a single spin — no bonus rounds or modifiers needed.

Piggy Bank Bills is on tap at Dream Vegas, along with a bevy of other titles from top providers like NetEnt, Evolution Gaming, and more.

New Slots UK FAQs

Is Playing at UK Slot Sites Legal?

Yes, playing online slots is legal in the UK, so long as you’re at least 18 years old and the casino sites you play on hold a remote gambling license. 

Can I Trust Online Slot Sites?

That depends on the online casino. Some are more reputable than others, so you should look for the following before making an account anywhere:

Fully licensed: if the site doesn’t have a remote gaming license, then there’s no reason for you to trust it (and it’s illegal for you to play there)

Reputable banking options: if established brands like Visa, MasterCard, and the like won’t do business with the online casino, why should you?

Solid reviews: check to see what current and former players have to say about it. If it has a bad reputation, proceed with caution

How Do I Get Money on and off the Slot Sites?

Each site will have its own set of banking providers that it works with. These can range from big-time credit cards like Visa and MasterCard to e-wallets like Neteller, and some even accept cryptocurrencies like Bitcoin as well.

Are Some Slot Games “Looser” Than Others?

Yes and no. There are a lot of myths and superstitions surrounding slots, both online and in real life, including the idea that some slot games are designed to be “loose,” meaning that they’ll pay out more than others. 

The thought is that, when gamblers see that those machines are rewarding players, they’ll be encouraged to bet on other machines as well — and those machines won’t pay out much at all.

That’s not true. However, it is true that certain games have higher returns than others, but that’s all part of the design.

It’s called “return to player (RTP),” and it’s expressed in percentages. For example, a machine that has an RTP of 96% will pay out 96% of every dollar wagered. Another way to express this is that the house has a 4% advantage on that machine.

Different titles will have different RTPs. While you might think it’s best to just seek out the machines with the highest RTP, keep in mind that most companies offset that higher percentage by offering lower payouts.

What Does Volatility Mean in Regards to Online Slots?

This is similar to RTP. Each game will have a pre-programmed “hit rate,” which is how often it will allow the player to win. The higher the hit rate, the less volatile the machine is said to be.

As with RTP, though, lower volatility is usually accompanied by lower payouts. That means you’ll have to choose between winning small amounts more frequently or having long dry stretches interrupted by bigger payouts.

Is There a Best Time of Day to Play Online Slots?

This is another superstition surrounding slot machines. The idea is that a slot site will designate certain times of the day to make their machines pay out more in order to cause players to gamble more.

It’s absolute rubbish, though. Your odds of winning will be the same no matter when you play, so the best time is whenever you feel like it.

What Are Progressive Jackpots?

A progressive jackpot is a jackpot that increases by a set amount every time the game is played and the jackpot is not won. 

Over time, progressive jackpots can get quite massive, and some can grow into the millions. 

How Do I Choose the Best Online Slot Games for Me?

When choosing the best online slot for you, you need to consider these things:

High RTP

Fun Theme (or lack thereof)

Sharp Graphics

Generous Jackpot size

Low Volatility

Ease of use

Mobile-friendliness

At the end of the day, it’s going to be your preference as a player that will greatly influence your choice of slot.
