Relax Gaming is a Malta-based B2B slot studio and content aggregator, licensed by the UKGC, MGA and Gibraltar regulators, and best known for the Money Train series and the Dream Drop progressive jackpot network. This guide covers verified RTP and max-win figures for the headline titles, the ownership chain now running to FDJ United, and the UK casinos carrying the catalogue.
Relax Gaming was founded in 2010 by Jani Tekoniemi and Patrik Österåker and is headquartered at Level 8, The Centre, Tigne Point, Sliema, Malta. Relax Gaming slots reach players through two channels at once: a developer arm producing its own titles, and an aggregator distributing third-party studios through its Silver Bullet and Powered By Relax programmes. That dual model separates it from a pure studio such as Pragmatic Play's provider profile, which reaches the same operators by direct integration only.
Ownership has moved twice in five years. Kindred Group, a shareholder since 2013, completed its full acquisition on 1 October 2021 at a €320 million enterprise value. Kindred was then acquired by La Française des Jeux — now trading as FDJ United — which closed on 2 October 2024 after securing 90.66% of Kindred's depositary receipts in a €2.45 billion tender offer. Relax continues to operate as an independent B2B entity inside that group, and Relax Gaming slots still ship under the studio's own brand.
The best Relax Gaming slots carry most of the studio's UK lobby traffic: the Money Train franchise, Book of 99 at the top of the RTP league, and the Dream Drop network. RTP, volatility and bonus mechanics all change over time, so confirm current figures in the operator help panel before depositing.
Each of the best Relax Gaming slots below is verified against the studio's own product pages and cross-checked against BigWinBoard, SlotCatalog and FruitySlots. GB cash equivalents use the £5 statutory stake cap for players aged 25 and over; £2 applies to the 18–24 cohort.
| Title | Year | Base RTP | Volatility | Max Win |
|---|---|---|---|---|
| Book of 99 | 2021 | 99.00% | High | 12,075x |
| Money Train 4 | 2023 | 96.10% | Very high | 150,000x |
| Money Train 3 | 2022 | 96.10% | High | 100,000x |
| Money Train 2 | 2020 | 96.40% | High | 50,000x |
| Iron Bank | 2020 | 96.20% | High | 49,999x |
| Temple Tumble Megaways | 2019 | 96.25% | High | 7,767x |
| Templar Tumble 2 Dream Drop | 2022 | 94.00% | High | 20,000x + jackpot |
| Snake Arena | 2019 | 96.25% | High | 2,758x |
Released 4 May 2021 on a 5×3 grid with 10 paylines, this is the RTP flagship at a headline 99.00%. Anyone arriving from the genre's defining original will find the contrast set out in the Book of Dead review, which covers where the two studios part company on volatility. Volatility is rated 5/5 and the 12,075x ceiling is worth £60,375 at the £5 cap or £24,150 at £2.
Released September 2023 as the intended series finale, Money Train 4 runs a 6×6 scatter-pays grid at 96.10% RTP with a 150,000x top prize — £750,000 at the £5 cap, £300,000 at £2. Volatility is 5/5 and hit frequency 20.14%. Operators may configure 94% or 90% builds, so check the live figure first.
September 2020, 5×4 grid, 40 paylines, 96.40% RTP, 50,000x max win — £250,000 at the £5 cap or £100,000 at £2. Its Money Cart round introduced the hold-and-respin engine and the persistent-symbol system every later Relax title has iterated on. Feature-buy builds at 98.00% RTP exist abroad but cannot be served here.
Built in 2020 with the CasinoGrounds community, Iron Bank offers 4,096 ways across a 6×4 grid and three selectable free-spins modes. Base RTP is 96.20%, max win 49,998.9x — £249,995 at the £5 cap, £99,998 at £2.
Released 6 February 2019, this was the studio's first title on Big Time Gaming's licensed Megaways engine: 6×6 grid, up to 46,656 ways, 96.25% RTP, 7,767x max win — £38,835 at the £5 cap or £15,534 at £2. A modest ceiling by Money Train standards, but the block-clearing mechanic has kept it in UK lobbies for six years.
The technical stack rests on the game studio itself and on Relax Apex, the aggregation platform launched in June 2021 that distributes both proprietary content and partner studios. All Relax Gaming slots are HTML5-native and certified against the jurisdictions the studio is licensed in.
Proprietary mechanic families include the Money Cart hold-and-respin engine, the Dream Drop jackpot network, the Tumble series' cascading-reel structure, and Bonus Reels, a mode stripping out the base game for direct bonus purchase in markets that permit it. The Megaways engine on the Tumble titles is licensed from Big Time Gaming rather than proprietary. The full set of regulated points of supply is published on Relax Gaming's licence-info page, which remains the reference for which products are certified where.
The first-party Relax Gaming slots catalogue runs to roughly 200–250 titles depending on which aggregator database is consulted, with two to four launches a month across the wider group. Alongside slots sit HexaPro poker, launched December 2018, and Relax Bingo, launched 2015.
UK distribution reaches LeoVegas, MrQ, Sky Vegas, Ladbrokes, Coral, BetVictor, 32Red, Boylesports, Jackpotjoy, Casumo and Mr Green. The Gibraltar-arm UKGC licence granted 31 March 2021 opened integration with Entain's Ladbrokes and Coral brands.
The company began in B2B poker distribution, launching a Fast Poker Network variant in 2012 before Kindred took its opening stake in 2013. Bingo followed in 2015, and 2018 brought the casino platform and the Silver Bullet distribution model.
The slot franchise era ran from 2019, when Money Train and Temple Tumble Megaways launched, through Money Train 2 in 2020 and Book of 99 in 2021. Dream Drop arrived in May 2022, Money Train 4 in September 2023, and the US entry via RLX Gaming reached New Jersey and Pennsylvania in March 2026.

Dream Drop is a five-tier progressive network running on Relax Apex. Tiers seed at Rapid €1, Midi €5, Maxi €100, Major €25,000 and Mega €500,000, with the Mega capped by a must-drop-by ceiling of €10 million rather than growing without limit. On that structure it belongs with our progressive jackpot slots hub rather than the studio's standard high-volatility bracket.
Relax Gaming slots carrying the mechanic include Temple Tumble 2 Dream Drop, the first at launch in May 2022, plus Templar Tumble 2 Dream Drop, Wild Chapo Dream Drop, Cod of Thunder Dream Drop and Purrrminator Dream Drop. Base-game RTPs on network titles typically sit between 93.75% and 94.10%, because roughly 12% of stake feeds the jackpot pool. Relax confirmed its 29th Mega winner in March 2026, with individual Mega prizes ranging from just over €1 million to €2.9 million.
Relax Gaming slots share three mechanic families. Money Cart is the hold-and-respin bonus running across the Money Train franchise and spun out into standalone titles such as Money Cart Bonus Reels. It grants three respins on a cleared grid, every landed symbol resets the counter, and persistent Collectors, Payers and Snipers interact across respins to compound value.
The Tumble series layers cascading reels over a variable grid, with blocker symbols cleared during free spins to unlock further rows. Bonus Reels, introduced in 2024, removes the base game entirely — unavailable at UKGC-licensed operators, where feature buys have been off the table since 2020 under RTS 14A.
Relax Gaming slots UK availability spans most major UKGC-licensed operators, supported by two B2B licences held by the studio: account 37462 for the Malta entity and 57758 for the Gibraltar entity, both on the UKGC public register. Lobby depth rather than raw availability is the deciding factor between operators.
| Casino | Welcome Offer | Wagering | Licensee |
|---|---|---|---|
| Sky Vegas | 50 no-deposit spins + 200 after £10 stake | Wager-free | Bonne Terre Gaming Ltd (65519) |
| LeoVegas | 50 spins on Big Bass Splash after £10 deposit | Wager-free | LeoVegas Gaming PLC (39198) |
| MrQ | 100 spins on Fishin' BIGGER Pots after £10 stake | Wager-free | Tek Fox Ltd (ex-Lindar Media) |
| Ladbrokes | 100 spins on selected slots after £10 stake | Wager-free | LC International Ltd (54743) |
Sky Vegas carries the broadest range of the best Relax Gaming slots in the mainstream UK lobby set and surfaces Dream Drop meters directly on the game tiles. LeoVegas, MGM-owned since September 2022, has integrated Relax since the studio's early UKGC years and stocks every Money Train title alongside the Dream Drop network.
MrQ operates under Tek Fox Ltd, formerly Lindar Media, acquired by Kindred in 2022 and now inside FDJ United. Its catalogue is leaner but curated around the headline titles. Ladbrokes shares the LC International licence with Coral and carries the Relax catalogue through the Entain platform, though its welcome spins are restricted to Blueprint titles.
Any casino stocking these games must hold a valid remote licence, verifiable on the UK Gambling Commission public register. The GB stake cap — £5 per game cycle for players 25 and over from 9 April 2025, £2 for 18–24s from 21 May 2025 — applies at every licensed operator regardless of the developer's default maximum, which runs to €100 in other markets.
A Relax Gaming slot demo is available across most third-party aggregators and at licensed operators pre-login, and every headline title has a Relax Gaming slot demo build in circulation. What free play cannot confirm is the live real-money RTP configuration for Relax Gaming slots at the operator you eventually deposit with. Where a UKGC-licensed operator hosts a play-for-free version alongside the real-money game, that version should represent it accurately under RTS 6.
The practical use of a Relax Gaming slot demo is auditing base-game rhythm before committing bankroll: Money Train titles pay very little between triggers by design.
Every Relax Gaming slots mobile build is HTML5-native and renders across iOS Safari, Android Chrome and operator app wrappers without a dedicated client. Portrait legibility is strong on the 5×4 grids and adequate on the 6×6 layouts, though the denser Megaways engines can crowd on smaller phone screens. Dream Drop meters display above the reels in portrait and to the side in landscape, consistently across every Relax Gaming slots UK build.
Most titles ship with multiple RTP configurations — the Money Train series at 96.10%, 94.00% and 90.00%, Iron Bank as low as 94.00% at some sites. The figure quoted on developer pages is the highest available build, not a guarantee. Every licensed casino shows the live figure in the in-game help panel once the game loads in real-money mode. Where a headline Relax Gaming slots RTP has been independently confirmed, it is logged in our high-RTP slots ranking alongside the operator variance worth checking first.
Relax Gaming slots RTP figures tell only half the story, because volatility runs high to very high across the flagship titles. Published hit frequencies — 20.14% on Money Train 4, 28.49% on Iron Bank, 29.83% on Book of 99 — mean most spins return below stake. A working ratio for meaningful exposure to a Money Cart or Dream Drop trigger sits around 1:150 to 1:200, so at £1 stakes plan a session bankroll of £150 upward. Bonus-trigger frequency is not disclosed for most of the catalogue, so plan on budget and time rather than expected triggers.
Playing Relax Gaming slots UK-side means playing at operators holding a UKGC remote casino licence, subject to the LCCP. Current reforms are all live: the stake caps, the 10x bonus wagering cap from 19 January 2026, the 40% Remote Gaming Duty from 1 April 2026, and the RTS 14D minimum 2.5-second game cycle.
Every licensed operator must offer deposit limits, session reminders, loss limits and self-exclusion from account settings. Reality Check timers start at 15 minutes and interrupt play with a summary of duration and net position — better set before a session than mid-session.
GamCare runs the National Gambling Helpline on 0808 8020 133 with 24/7 confidential support. GamStop provides free UK-wide self-exclusion across every licensed operator for six months, one year or five years. BeGambleAware offers information and treatment referrals.
