The Great Pigsby comes with 243 paylines and you can bet anything from 10p up to £200, making it a good all-rounder for casual players and high rollers alike.

Marching Legions is one of the most underrated slots if you ask me. In this Rome-themed slot, you can enjoy a bunch of bonus features like free spins and respins. The RTP is extremely generous and stands at 98.12%, second only to Book of 99. The maximum payouts are also decent, as you can win up to 10,000 times your bet.
What may be a turn-off for some players is the slot’s 3D design. It is a matter of personal preference, and while some players like it, others do not. The graphics, however, are solid.

RTP: 96.00%
Maximum win: 10,000x your bet
Theme rating: 4/5
Overall score: 4/5
Are you a player who prefers the bonus rounds of slots over everything else? Then Money Cart 3 is the Relax Gaming slot you want to play as it is more or or less one big bonus game. In its base game you cannot win any cash prizes, instead you have one sole mission – get to the bonus game. Once you reach it, prepare yourself for tons of action and fun features.
Keep in mind that Money Cart 3 is a slot with high volatility, which means you can both win and lose your stake very quickly. You should therefore only play this game if you can handle big swings in both directions.

WHERE CAN I PLAY RELAX GAMING SLOTS?
There are plenty of slot sites and new online slot sites which have libraries full of Relax Gaming video slots. However, in order for casino operators to offer Relax Gaming games to their players, they must have a license from the developers.
Relax Gaming are one of the most popular slots developers around, so there is no shortage of online casinos offering their games. In fact, you can expect to find Relax Gaming online slots at almost every casino site in the UK. Our two favourites are Skol Casino and Slotnite Casino because they offer more games from Relax Gaming than anyone else. Other good Relax Gaming slot sites include Casumo Casino, MrQ Casino and PlayOJO Casino. You can find all of them in the list below:

WHAT KIND OF SLOTS DOES RELAX GAMING OFFER?
You may be surprised to know that Relax Gaming was not initially launched as a slot studio. They were founded in 2010 as an open online casino platform that offered games from various game developers to online gambling sites. In 2018 that changed when they created their first own video slot in Erik the Red, and since then they have developed close to another 100 games.
Today, Relax Gaming offers several different types of online slots, and they have recently started producing Megaways slots and progressive jackpots. Here are the ones you can expect to play online in the UK:
- Video Slots – You will find many classic video slots with a modern twist. Money Train 2 and Iron bank are the two slots we had the most fun playing.
- Megaways Slots – Relax Gaming has received permission from Big Time Gaming to use the Megaways mechanic. Right now there are a few titles in this category. The Great Pigsby Megaways and Temple Tumble Megaways are the most popular.
- Cluster Pays Slots – Cluster Pays is a unique slot mechanic where there are no paylines, but instead you win when matching symbols cluster together. Two such slots are listed at the top of the page (Kluster Krystals Megaclusters and Cluster Tumble).
- Progressive Jackpot Slots – In May 2022, Relax Gaming launched its own jackpot series in Dream Drop Jackpots. It is a progressive jackpot and you can win up to €10 million. There are a total of 15 slots in the series. Some notable ones are Banana Town Dream Drop, TNT Tumble Dream Drop, Wild Chapo Dream Drop, Temple Tumble 2 Dream Drop and Beellionaires Dream Drop
RELAX GAMING REVIEW
In my opinion, Relax Gaming is one of the most prominent slots providers not only in the UK but in the whole world right now. They do many things right, especially when it comes to delivering slots with a good payback percentage. Compared to other game developers, Relax Gaming offers a very high RTP on their slots, which as you may have realised by now, we at SlotsHawk think is a very important ingredient in creating a good slot game. Almost every slot that Relax gaming develops has an RTP above 96%, and the majority are above the market average of 96.20%. Moreover, some of their slots like Book of 99, Marching Legions and Money Cart 2 have an excellent RTP rate above 98%.
When it comes to graphics and game features, they are as modern as it gets. There is a simple reason behind this – Relax Gaming did not start to create their own slots until 2018. So, they do not have any old legacy lingering around in certain games like many of the veterans in the casino industry do.
As for the gambling licence, everything is in order. Relax Gaming has bingo, casino and gambling software licences from the UK Gambling Commission registered under account number 37462. They are therefore considered to be legitimate.
So is it worth playing Relax Gaming Slots? If RTP and modern gaming features are two things that you prioritise then the answer is definitely yes.
