The success recorded in interactive gaming may not have been possible without the conscious efforts made by title developers and software providers. These brands help bridge the gap by creating content tailored to either the online casinos or to the jurisdiction they’re meant to be played in.

Relax Gaming is not a newbie in this industry, as it has been existing for more than a decade. It started in 2010 to create novel solutions that would take the industry to greater heights. By focusing on the provision of technical and high-quality slot solutions, it helped introduce newer mechanics to the market.
One thing that sets Relax Gaming online slots out from the competitors is that they’re designed on a B2B basis. Against this backdrop, the company offers the software solutions directly to partners, such as online casinos. Those, in turn, deliver the content down to the players.
This business model is further bolstered by the high production value and innovative slot mechanics, such as Dream Drop Jackpots and Megaways.
Relax Gaming has since capitalized on this market opportunity to lead in innovation through feature-rich slot development. These include the Temple Tumble Megaways, offering up to 46,500 winning pathways.

The first set of Relax Gaming best slots didn’t hit the market until September 2018, following the release of Erik the Red. One may wonder why it took over eight years. But the company believes in getting things right from the word go.
Although it began to release reel machines a bit late, it had built upon its expertise in the past. This is true due to the launch of the flagship poker product in March 2014, just four years after its launch.
It took a notch higher with the launch of a casino platform in January 2015. This became the hallmark of getting their titles list to penetrate the market faster. It also helped the brand collaborate with studios to push the content to broader jurisdictions.
Over the 15 years of existence, it has recorded successes, such as:
Relax Gaming online slots have become the darling of the industry, coasting home with reputable recognitions. It’s worth mentioning that the awards didn’t start rolling in until some decades after the company started operating.
It began with the Casino Software Supplier of the Year Award received in 2020 at the EGR Awards. Likewise, it would also be recognized as the Provider of the Year and Game of the Year for Money Train 2.
Going home with those three awards and several nominations in the same year shows how committed Relax Gaming is to building a good name in the industry.
The following years saw it go home with Casino Content Supplier of the Year at the EGR Nordic Awards and a nomination in 2023 for the Best Game Developer.
Their library includes mobile-optimized content. This has distinguished the company from the others because it goes all the rounds to create a mobile-friendly play process experience for users across several facets like bingo, slots and bingo.
Their effort didn’t go unnoticed, as it was awarded the «Innovation in Mobile» at the 2021 EGR B2B Awards. This fetched it a nomination at the EiGE Awards for the «Best Mobile Gaming Provider» category.
One fascinating feature of the mobile play process has to be the identical mechanics, giving players the feel of playing from a desktop. This is in addition to specific titles, such as the Dream Drop, which work seamlessly on mobile devices.
With side menus containing the information and paytables, you can access everything from the same interface.
All their reel machines are designed with precision, excellent play processes, and feature-rich attributes in mind. Yet, some outshine the others, particularly because new players and professionals find them exciting.
Here are some of Relax Gaming best slots.
Temple Tumble 2 Dream Drop is the first on the list because it comes with heavy prizes. It’s not just for the high rollers but also for those who want to play and wager on progressive jackpot slots. It also comes packed with the Dream Drop jackpot system.
Next on the list is the Money Train series, from which Money Train 2 was picked out and nominated for an award. This series is notable for adrenaline-rush gameplay and maximum payouts running into their thousands. You can start with Money Train 2, which pays a maximum of 50,000 times, up to Money Train 4 with a $150,000 maximum payout and a plethora of other bonuses.
We won’t make mention of the Relax Gaming best slots without putting titles ideal for long-term play. These not only have a higher Return to Player, but also encourage long-term play. They include the likes of Mega Masks with 97% RTP and Book of 99 offering up to 99% of the winnings.
Keep in mind that you can choose to play any of these Relax slots demos to get a hang of what the gameplay is like. New players can start with Marching Legions or Book of 99 for longer play sessions. Then, take things a bit higher by playing Hellcatraz for huge wins.
The top-paying Relax Gaming casinos are not only ranked by the maximum win potential. We also look at the different returns they give and how risky they could be, especially for new players.
Starting the list is Money Train 4. It has up to 150,000 times the wagered amount as the highest payout. It also comes loaded with the Persistent Symbol modifiers and extreme volatility. New players may go for the big win, but they would need a betting strategy to navigate the extreme risk.
Another slot in the series, Money Train 3, comes second with 100,000x maximum win. It also has an extreme variance.
In the third spot is Sloth Tumble, an extreme video reel machine with a 100,000x maximum win. It packs a lot of features, like cascading reels. The gameplay also has lots of bonus features designed to help players stack multipliers to the highest levels possible.
The maximum win potential is an obvious reason why players want to take a blazing spin at any of the online casino slots developed by them. We reveal some of the reasons why playing and wagering on these titles wouldn’t be a bad idea.
You’ll find different categories on the Relax Gaming games list. From bingo to poker and reel machines, you’ll get games that match your taste.
They come with attributes like mobile-first, fun promotions and are available as mini games. These are all built in-house, allowing this software provider to leave innovation in every development made.
We saved the best for last. The big winnings are a part of the benefits of playing any of the Relax Gaming online slots. They can move from 50,000 to 150,000 times the wagered amount.
In addition to ranking as one of the highest in the industry, these also come with the following:

| Stunning visuals | From immersive soundtracks to detailed symbols, the range of their slots is designed with high-quality animations. |
| Jackpot feature | Some titles, especially Dream Drop, have progressive jackpots, which offer life-changing cash prizes. |
As a company that believes in dominating via innovation, it’s not surprising to see them lead in that regard, with innovative mechanics. From persistent symbols to megaclusters, they have been optimized to add extra gameplay twists.
