Some studios are famous for one legendary game. Relax Gaming is famous for a legendary game and a secret side hustle almost nobody notices. The game is Money Train, a slot so popular it has spawned sequel after sequel, each one paying more absurd money than the last. The side hustle is quietly running the technology that launched some of the biggest studios in the business.
Put those two things together and you get one of the most useful companies in online casino. It makes brilliant games with one hand and moves thousands of other studios’ games with the other. Most providers pick a lane. Relax Gaming drives down both at once.
Provider type: Game Studio and Aggregator. This is one of the rare companies that fits two boxes on our Provider Types filter. It builds its own slots like a Game Studio, and it distributes a huge library of third-party games like an Aggregator. Keep that split in mind, because it explains everything about how Relax works.
Who is Relax Gaming, in plain English
From behind-the-scenes plumbing to headline games
Relax Gaming was founded in 2010, and for its first several years it was not really a game maker at all. It was a B2B company that shifted other people’s content around and dabbled in poker and bingo tech. Useful, profitable, and about as glamorous as a plumbing supplier.
That changed in 2018, when Relax launched its first in-house slot, Erik the Red, and started building its own games in earnest. The gamble paid off spectacularly. By 2026 the studio has released more than 120 of its own slots, and a couple of them turned into franchises big enough to define the entire company.
The two hats it wears
To understand Relax Gaming, you have to hold two ideas at once. First, it is a creative studio that makes original slots, some of which are genuine blockbusters. Second, it is an aggregator, which is industry-speak for a company that bundles thousands of games from many different studios into one connection an online casino can plug into. One hat is about making. The other is about moving. Relax wears both, and that is unusual.
Money Train, the franchise that made Relax famous
How the Bonus Train actually works
Money Train arrived in 2019 and introduced the feature everyone remembers, the Bonus Train. In plain terms, you trigger a bonus round where special symbols land and stick to the reels, each carrying a cash value or a modifier. Every time a new symbol drops in, your respins reset, so the round keeps going and the values keep piling up. Collectors add everything together, multipliers pump it up, and on a good run the whole thing snowballs into a genuinely eye-watering number.
The sequels and the ever-climbing ceiling
One hit slot is nice. A franchise is a licence to print money, and Relax knew it. Money Train 2 sharpened the formula and pushed the maximum win to 50,000 times your bet, which turned it into one of the most talked-about slot releases in years. Money Train 3 cranked things further still. Then came Money Train 4 in 2025, with a full science-fiction makeover and a colossal top win of 150,000x. The train kept getting faster and the payouts kept getting sillier.
The most reluctant retirement in gaming
Here is a funny one. Relax marketed Money Train 4 as the final chapter, the last ride, the end of the line. Very dramatic. Then, in 2026, a teaser campaign got the whole industry whispering before Relax announced, with a straight face, Money Train 5. Turns out the last train had one more departure in it. If a slot series can have a running joke, this is it, and players love the studio for leaning into the drama rather than pretending it never happened.
Beyond Money Train
It would be a mistake to think Relax is a one-trick pony. The studio also built the Temple Tumble series, a cascading-reels favourite that spun off its own Megaways version. Its Dream Drop Jackpots are a bigger deal than casual players realise, a progressive jackpot system stitched across many games that has reportedly created more than 20 millionaires since it launched in 2022. That is real money landing in real accounts.
The back catalogue runs deep beyond that, from Snake Arena to Zombie Circus to Wildchemy, plus a steady stream of fresh 2026 releases keeping the lineup current. Whatever mood you are in, Relax usually has a slot for it, and the ones tied to Dream Drop come with a life-changing jackpot bolted on top. You can read how prizes like these pay out in our guide to casino bonuses and promotions.
The secret second business: Powered By Relax and Silver Bullet
What aggregation actually means
Time for the invisible half of the company. Running an online casino means offering thousands of games, and signing a separate deal with every single studio would be a nightmare. Aggregators solve that. They bundle huge numbers of games behind one integration, so a casino plugs in once and instantly offers a giant library. Relax runs two of these programmes, and together they connect over 7,000 games from more than 50 partner studios to 900-plus operator brands.
The studios Relax helped launch
This is where the story gets genuinely cool. Relax runs Powered By Relax, a platform where other studios build their games on Relax’s technology, borrowing its remote gaming server, maths tools, and certifications.
Both Nolimit City and Hacksaw Gaming launched through it before growing big enough to stand alone. Relax also runs Silver Bullet, a curated programme that hand-picks promising up-and-coming studios and pushes their games out across its operator network. In effect, Relax has been a launchpad for some of the most exciting names in modern slots. Fame by association, and it earned it.
Who owns Relax Gaming
Despite the rebel energy, Relax is not an independent outfit anymore. Kindred Group, one of the largest names in online gambling, completed its acquisition of Relax Gaming in October 2021. The upside for players is that Relax kept its own management and creative direction rather than being flattened into a faceless corporate unit. It sits inside a huge group, yet still makes games that feel like Relax rather than committee output.
What Relax Gaming is like to play, and where
Mobile-first, fair, and tested
Every Relax slot is built in HTML5, which is the dull way of saying it runs straight in your phone browser with no app and no download. Mobile was the priority from the start, so the games load quickly and behave properly on a small screen. On fairness, the maths runs on tested random number generators and the studio holds licences from serious regulators, so the odds you are quoted are the odds you actually get.
How to spot Relax Gaming in a lobby
Finding Relax games is easy money. Most casinos let you filter the lobby by provider, and Relax Gaming is nearly always on the list. Even without the filter, the hits give it away. Spot any Money Train title, a Temple Tumble, a Snake Arena, or a slot flashing a Dream Drop jackpot banner, and you are looking at Relax.
The Dream Drop label is the one worth hunting for, since it means a shared progressive prize is stacked on top of whatever you spin. Worth knowing too: some games you would never guess are Relax at all, because they were built by partner studios on the Powered By Relax platform rather than by the in-house team. The name on the game is not always the name running the maths underneath.
Bonus buys, big wins and getting paid
Money Train and its cousins usually offer a bonus buy, letting you pay a premium to jump straight into the feature. It is a fast track and a fast way to spend, so handle with care. You will find Relax games at a broad mix of licensed sites, including plenty of crypto casinos that court the high-volatility crowd. Since these slots can occasionally pay enormous sums, and Dream Drop jackpots even more, it pays to check a casino’s payment methods and withdrawal limits before you deposit, because a giant win is only satisfying if the cashier can actually handle it.
A quick, honest word on risk
The Money Train games are high volatility by design, so expect long quiet spells between the fireworks. Those 150,000x headlines are the dream, not the plan. Set a budget you are relaxed about losing, treat the top prize as a lottery ticket, and the games stay fun instead of frustrating.
Relax Gaming in 2026
The company is moving on every front. Money Train 4 landed in 2025, Money Train 5 is on the way after that cheeky teaser, and 2026 has brought fresh releases like the ClusterBreaker-powered Midnight Marauder and a first-ever football-themed Dream Drop slot timed for a big tournament year. On the business side, Relax has been expanding its aggregation service into new markets, including the United States, widening the pipe even further.
The dual strategy is clearly working. Relax keeps its name in lights with marquee games while quietly powering a chunk of the industry behind the curtain. Few companies manage to be both the star and the stage crew, and fewer still do it this well.
The bottom line
Relax Gaming is one of the smartest operators in online casino, in both senses of the word. Its Money Train series is a modern classic with payouts that border on the ridiculous, its Dream Drop jackpots turn ordinary players into millionaires, and its aggregation platforms quietly helped launch some of the biggest studios going. Whether you know its name or not, you have almost certainly played a game that Relax either made or moved. You will find its slots across most of our top-rated casinos and plenty of other online casinos too.
