Overview
Relax Gaming occupies a unusual position in the industry. They’re simultaneously a game developer — producing their own slots, poker, and bingo products — and a distribution platform that delivers thousands of games from partner studios to casinos worldwide. Understanding this dual identity is essential to evaluating them properly, because most of the 4,000+ games accessible through their platform aren’t games they built.
The company was founded in March 2010 in Malta by Patrik Österåker and Jani Tekoniemi. The story is that they sketched out the idea in a pub, envisioning a company that would simplify B2B game delivery. Early success came through a poker partnership with Unibet, followed by bingo, and eventually their own slot portfolio. Kindred Group (Unibet’s parent company) gradually increased its stake, becoming the largest shareholder by 2013 and completing a full acquisition in October 2021 for €320 million. Relax operates as an independent entity within Kindred, with offices in Malta, Tallinn, Malmö, Belgrade, and Gibraltar.
What makes Relax genuinely interesting is the quality gap between their proprietary games and the industry average. The Money Train series, the Tumble games, Book of 99 — these are among the most respected slots in the market. Their Dream Drop Jackpot system has redefined what progressive jackpots look like in 2025. The platform side is solid infrastructure; the games side is where the creative ambition lives.
Game Portfolio
The numbers require context. Relax’s Silver Bullet aggregation platform distributes over 4,000 titles from dozens of partner studios. But Relax’s own proprietary catalog sits at roughly 140+ slots, plus poker and bingo products. These are the games Relax actually designed, built, and maintains — and they’re the ones this review focuses on.
The proprietary portfolio punches well above its size. The Money Train series (four entries plus Dream Drop variants) established Relax as a serious slot developer. The Tumble franchise (Temple Tumble, Cluster Tumble, and their various Dream Drop editions) showcases cascade mechanics with escalating multipliers. Standalone titles like Snake Arena, Hellcatraz, and Iron Bank round out a catalog that leans toward medium-to-high volatility with strong feature depth.
Thematically, Relax covers wide ground — Western heists, ancient temples, underwater adventures, steampunk vaults, mythological settings. There’s no single aesthetic identity the way you’d associate Nolimit City with dark themes or BGaming with bright, accessible designs. What unifies Relax’s games is mechanical ambition: they consistently introduce new feature concepts and refine existing ones rather than reskinning the same template.
Signature Features
Dream Drop Jackpots
Launched in May 2022 with Temple Tumble 2 Dream Drop, this is Relax’s answer to the problem that traditional progressive jackpots feel unwinnable. Dream Drop uses five tiers — Rapid, Midi, Maxi, Major, and Mega — with the Mega Jackpot starting at €500,000 and capped at €2 million. It pays out roughly every four to six weeks. In 2025, Relax added three guaranteed daily jackpots on top of the existing tiers.
The system spans over 50 participating games from both Relax and partner studios like 4ThePlayer and Four Leaf Gaming. A portion of each bet (typically 12% of the RTP) feeds the jackpot pool. The Dream Drop feature triggers randomly during play — when it does, you enter a mini-game (wheel, pick, trail, or Plinko-style depending on the slot) that determines which tier you win. Every entry guarantees a jackpot of some level.
What separates Dream Drop from older progressives is the payout frequency and the guaranteed entry mechanic. You’re not chasing a jackpot that hasn’t paid in six months. The Mega hits regularly, and the lower tiers hit constantly. Over 200 Major Jackpot winners have been recorded, with multiple Mega wins exceeding €2 million.
Silver Bullet Platform
The aggregation side of the business. Silver Bullet lets operators access thousands of games from partner studios through a single integration. For smaller studios, it provides distribution reach they couldn’t achieve independently. For operators, it simplifies their technical stack. Studios like AvatarUX, Trigger Studios, and Northern Lights Gaming have used the platform to scale their market presence.
Relax later introduced Relax Apex, a next-generation overlay that streamlined QA, compliance, and promotional tool access for connected operators. The platform isn’t just a pipe — it includes promotional engines, tournament systems, and compliance management.
Money Train Mechanics
The Money Train series developed its own ecosystem of mechanics across four main entries. The core is a Money Cart Bonus — essentially a Hold and Win respin round with persistent special symbols that modify, multiply, collect, and reset values. Money Train 2 pushed the max win to 50,000x. Money Train 3 introduced new symbol types and raised complexity. Money Train 4 cranked the ceiling to 150,000x. Each entry refined the formula without abandoning what made the original compelling.
Top Games
| Game | RTP | Max Win | Volatility | Notable Feature |
|---|---|---|---|---|
| Money Train 2 | 96.40% | 50,000x | High | Money Cart Bonus with persistent modifiers |
| Money Train 3 | 96.10% | 50,000x | High | Respin Evolution with new symbol types |
| Money Train 4 | 96.00% | 150,000x | Very High | Highest max win in the series |
| Temple Tumble | 96.25% | 4,741x | High | Block-breaking cascade mechanic |
| Book of 99 | 99.00% | 4,500x | Medium | Highest RTP of any mainstream slot |
| Snake Arena | 96.25% | 2,000x | High | Gladiator battles determine wild placements |
Money Train 2 is the game that put Relax on the map for slot enthusiasts. The Money Cart Bonus became a template for how respin features could work with layered modifier symbols — Payers, Collectors, Snipers, Necromancers — each with distinct effects that interact with each other. It’s one of the most influential slot designs of the last five years, and its 50,000x max win remains among the highest for any non-Nolimit City title.
Book of 99 deserves special mention for its 99% RTP — the highest of any widely available slot. The house edge is just 1%, which is exceptional. The gameplay is a straightforward book-style slot (expanding symbols during free spins), so the appeal is almost entirely mathematical. For players who prioritize return over flashy mechanics, it’s essentially the best deal in online slots. It would sit at the top of any high RTP slots ranking.
RTP and Fairness
Relax Gaming’s RTP range is the widest of any major provider. At the top end, Book of 99 offers 99% and Marching Legions sits at 98.12%. The majority of the proprietary catalog falls between 94% and 96.5%. Dream Drop games typically show 94% base RTP because 12% of the total return is allocated to the jackpot pool — meaning the effective RTP including jackpots is higher, but the base game return is lower.
Relax holds licences from the Malta Gaming Authority, UK Gambling Commission, Alderney Gambling Control Commission, and Romania’s ONJN. Games are audited by eCOGRA for RNG certification. As with most modern providers, operator-configurable RTP is available on some titles, so checking the in-game paytable at your specific casino remains important.
Pros and Cons
| Pros | Cons |
|---|---|
| Money Train series is among the best respin slot franchises ever made | Dream Drop games have lower base RTP (~94%) due to jackpot allocation |
| Dream Drop Jackpots offer realistic, regular progressive wins | Proprietary catalog (~140 slots) is smaller than many competitors |
| Book of 99’s 99% RTP is unmatched in the industry | Some titles feel secondary to the flagship franchises |
| Strong regulatory standing (MGA, UKGC, Alderney, Romania) | Platform games from partner studios vary widely in quality |
| Consistent mechanical innovation across releases | High volatility focus may not suit casual players |
Verdict
Relax Gaming’s strength is concentration. They haven’t flooded the market with hundreds of forgettable titles — they’ve built a focused portfolio of ~140 games where the top tier (Money Train series, Tumble franchise, Book of 99) competes with the best output from any studio. The Dream Drop Jackpot system is genuinely the best progressive product in the current market, solving the fundamental problem of traditional progressives by guaranteeing regular, meaningful payouts.
The aggregation platform adds business value for operators but doesn’t directly affect player experience — you’re either playing a Relax-built game (which will be polished, mechanically interesting, and well-tested) or a partner studio game (which could be anything). The Relax name on the platform doesn’t guarantee quality for third-party titles.
For players, the recommendation is simple: the proprietary Relax games are among the best available. Money Train 2 remains a modern classic. Book of 99 is the fairest slot in the industry by raw numbers. And if you want a shot at a progressive jackpot without feeling like you’re throwing money away, Dream Drop is the most player-friendly system currently operating. The studio’s output may be modest in volume, but the hit rate on quality is remarkably high.
