Relax Gaming Slots

Relax Gaming Slots Overview

Relax Gaming is a Malta-headquartered developer founded in 2010, acquired by Kindred Group in 2021 and subsequently absorbed into La Française des Jeux (FDJ United) following FDJ’s takeover of Kindred in 2024. The studio holds UK Gambling Commission approval and operates on two tracks — an in-house game studio producing the Money Train and Temple Tumble series, and the Silver Bullet and Powered By aggregation programmes that distribute content from partner studios. The Dream Drop progressive jackpot network, launched in 2022, has become one of the most played jackpot systems at UK casinos. Relax Gaming slots blend mainstream accessibility with genuinely high-ceiling volatility releases.

Best Relax Gaming Slots Ranked

The table below ranks the most popular in-house Relax Gaming slots by a combination of max win, RTP, and sustained player demand at UK casinos in 2026. Detailed breakdowns follow each entry.

Money Train 4

The current flagship in Relax Gaming’s most successful franchise, Money Train 4 runs at 96.10% RTP with a 150,000x max win and extreme volatility. The Money Cart bonus — triggered by three or more scatters — is the sole win vehicle, and the round fills with persistent value symbols, Payer symbols that distribute to others, Collector symbols that gather adjacent values, and powerful hybrid symbols that combine both roles. The maths rewards extended bonus rounds where collectors and payers interact across the grid. UK players treat Money Train 4 as the benchmark for extreme-volatility mainstream slots, and most UKGC casinos carry it at default RTP.

Money Train 3

Money Train 3 kept the 96.10% RTP but introduced the Necromancer symbol — a wildcard that can assume Payer, Collector, or any hybrid role at random, producing the largest possible endgame combinations. The 100,000x max win sits below MT4 but the bonus pacing is tighter, with persistent symbols upgrading through levels across successive respins. Extreme volatility means dry stretches between triggers are genuine, but the bonus-round reputation is what cemented the game as a cult release. Still widely stocked at UK casinos in 2026 despite being superseded by the fourth instalment.

Money Train 2

The 2020 release that made the franchise a fixture at UK casinos. 96.40% RTP, 50,000x max win, and the first entry to introduce Payer, Collector, and Persistent symbol types. Extreme volatility and a Money Cart bonus round that can extend significantly when persistent symbols keep respins alive. The softer max-win ceiling compared to later entries is balanced by a slightly higher RTP, making it the most mathematically friendly entry in the series. A reasonable starting point for UK players new to the Money Train formula before moving on to the more punishing third and fourth instalments.

Money Train

The original 2019 release runs at a 98.00% RTP — a standout figure for the UK market — with a 20,000x max win and a softer high-volatility rating. The bonus round uses a respin format without the full Payer/Collector system of later entries, and value symbols accumulate as reels lock between respins. Less feature-dense than its sequels but considerably more generous in long-term maths. Some UK operators stock reduced RTP versions of Money Train at 94% or 96% — always check the paytable, as the 98% build is the one that built the franchise’s reputation.

Hellcatraz 2

Hellcatraz 2 operates on a 6×6 cluster-pays grid with 96.16% RTP and a 75,000x max win. The core mechanic is a cascading cluster engine where destroyed symbols reveal multiplier values that attach to a running bonus meter. Free spins trigger a dedicated multiplier trail that persists across spins, and the round can scale significantly when multipliers chain. Extreme volatility, genuine endgame potential, and one of the most atmospheric presentations in the Relax Gaming catalogue. UK players familiar with Hacksaw Gaming style cluster slots will find the format immediately comfortable.

Temple Tumble 2 Dream Drop

The Dream Drop jackpot network variant of the original Temple Tumble. 96.10% RTP, 25,000x max win, and five-tier progressive jackpots ranging from Rapid (seeded small) to Mega (often £750,000+ at peak). Tumbling reels remove winning combinations and progressively demolish temple blocks, increasing paylines as the grid opens up. The jackpot trigger is random rather than feature-based, meaning any spin at any stake can hit. High volatility, strong mid-tier potential, and genuine network jackpot integration make this one of the most popular Relax Gaming slots at UK casinos in 2026.

Temple Tumble Megaways

A Megaways adaptation of the original Temple Tumble, using the Big Time Gaming engine under licence. 96.25% RTP, 7,776x max win, and up to 46,656 ways to win during bonus rounds. The temple-block mechanic from the original carries over, with destroyed blocks expanding the ways-to-win count on every tumble. High volatility with generous mid-game payouts. The max-win ceiling is lower than the Dream Drop sequel, but the Megaways format delivers a different rhythm — faster cascades, more frequent small wins, and a bonus round that trades top-end scale for consistency.

Top Dawg$

A 2023 release that has held strong in UK lobbies through 2026. 96.11% RTP, 25,000x max win, and a cash-collect bonus round themed around urban street gameplay. Value symbols land with cash amounts printed on them, and collector symbols during free spins gather every value on the reels. Symbol upgrade mechanics during the bonus round push collected values higher as the round progresses. High volatility, clean collect pacing, and one of the better presented entries in the current Relax Gaming catalogue for players who enjoy cash-collect mechanics without the extreme variance of the Money Train series.

Snake Arena Dream Drop

A grid-based release built around a snake trail mechanic, running at 96.09% RTP with a 10,000x max win plus five-tier Dream Drop jackpot integration. The snake symbol grows across consecutive spins, adding wilds to its path, and collecting food symbols extends the snake and applies multipliers. High volatility, novel mechanics that differ meaningfully from the studio’s standard cash-collect and cluster formats, and the added jackpot upside via Dream Drop. Genuinely distinct from the rest of the Relax Gaming portfolio and worth trying for variety if you have been cycling through Money Train and Temple Tumble.

Marching Legions

A Roman-themed cluster-pays slot running at 96.28% RTP with a 30,000x max win. Wins are scored across cluster groupings of matching symbols, with the grid expanding during the free spins round to unlock additional positions and ways-to-win. High volatility, a strong feature trigger rate, and visually one of the more polished Relax Gaming releases. A good fit for players who prefer cluster-pays over payline-based slots but want a harder maths profile than typical NetEnt cluster releases like Starburst XXXtreme.

Iron Bank

A 5×3 bank-heist themed release with 96.12% RTP and a 20,000x max win. The signature mechanic is a value-symbol collect system paired with a progressive multiplier trail — each collected symbol increases the active multiplier, and the multiplier locks across the full free spins round. High volatility with structured bonus pacing that rewards extended feature rounds. Not as mechanically complex as Money Train, but one of the cleaner expressions of the Relax Gaming cash-collect formula and a sensible entry point for players new to the studio.

Beast Mode

A 2022 extreme-volatility release with 96.17% RTP and a 25,000x max win. The core mechanic is a beast transformation system — during free spins, a random low-paying symbol transforms into a high-paying beast, and subsequent wins can upgrade the beast further through multiple tiers. Extreme volatility is genuinely felt, with long dry stretches between bonus triggers, but the top-tier beast transformations produce some of the largest single-spin wins in the Relax Gaming catalogue relative to max. A strong pick for players who have outgrown mainstream volatility tiers but do not want the 100,000x+ ceilings of the Money Train series.

How Relax Gaming Slots Work

Relax Gaming’s in-house catalogue is built on a few recurring mechanics that appear across series in different configurations. Understanding the core components helps you pick the right titles for your bankroll and playing style.

Core Mechanic Explained

The defining Relax Gaming in-house mechanic is the persistent-symbol cash-collect system, most fully expressed in the Money Train series. In the Money Cart bonus round, value symbols land and stay locked in place for the duration of the feature. Payer symbols distribute their value to other positions, Collector symbols gather all visible values, and persistent symbols keep respins alive as long as new symbols keep landing. The interaction between payer, collector, and persistent symbols produces the series’s characteristic endgame sequences where bonus values can scale dramatically within a single round.

Signature Features & Bonus Rounds

Free spins and respin-based bonus rounds are the primary win vehicles across nearly every in-house Relax Gaming slot. The Money Cart format — triggered by scatters and consisting entirely of locked value symbols across multiple respins — is the studio’s most influential design. Dream Drop is the other signature feature: a five-tier progressive jackpot network (Rapid, Midi, Maxi, Major, Mega) attached to eligible games including Temple Tumble 2 Dream Drop and Snake Arena Dream Drop. Jackpots trigger randomly at any stake level, though higher stakes improve trigger probability across the network.

Common Features Across Relax Gaming Slots

Most in-house Relax Gaming slots share baseline design elements: extreme or high volatility profiles, RTPs clustering in the 96.09%–96.40% band (with outliers like the 98% original Money Train), scatter-triggered bonus rounds as the main feature, and Bonus Buy availability on most titles. Bonus Buy costs typically range from 80x to 500x depending on the game — Money Train titles sit at the higher end. Availability at UK casinos varies: most UKGC operators permit standard Bonus Buy, but some disable it or restrict specific buy tiers under responsible-gambling guidelines. All titles are HTML5 and fully mobile-optimised.

Relax Gaming Slots by Volatility

The in-house Relax Gaming portfolio skews heavily toward the high and extreme volatility tiers. Silver Bullet and Powered By partner titles fill out the softer end of the spectrum.

Low Volatility

There are effectively no low-volatility in-house Relax Gaming slots. The partner-aggregation catalogue includes softer titles from various studios, but the core Relax Gaming brand is built around high-variance design. Players looking for low-volatility alternatives are better served by provider-level options from studios like Red Tiger which cover the lower end of the spectrum more comprehensively.

Medium Volatility

A small handful of Relax Gaming slots sit in the medium-high range — primarily the original Money Train (2019) and certain branded releases. These offer the Relax Gaming design sensibility without the extreme variance of the main catalogue. Good entry points for players curious about the studio before committing to the harder titles.

High & Extreme Volatility

The majority of in-house Relax Gaming slots sit in the high-to-extreme tier. Money Train 2, 3, and 4, Hellcatraz 2, Beast Mode, and Temple Tumble Dream Drop are all rated extreme or high-with-extreme-leanings. Expect long stretches without meaningful wins punctuated by significant bonus payouts. These are not games that produce consistent base-play returns — the design philosophy is built entirely around the bonus-round maths. Players who enjoy this tier typically also play Nolimit City releases for similar variance profiles.

Relax Gaming Slots by Studio Programme

Relax Gaming operates three distinct production tracks: the in-house studio, the Silver Bullet partnership programme (exclusive distribution deals with independent studios), and Powered By (technology licensing to larger partners). The table below shows flagship titles across each track.

New Relax Gaming Slots in 2026

Relax Gaming’s 2026 release schedule has focused on Dream Drop expansion and series continuation rather than fresh IP. Money Cart 4 launched in Q1 as a scatter-only Money Train spinoff with a 100,000x max win and a reworked respin pacing system. Temple Tumble Forever Dream Drop arrived in March as an expanded jackpot variant with six demolition tiers and a higher base max win of 30,000x. Beast Mode 2 is confirmed for Q3 with an upgraded transformation system and a 50,000x ceiling. Partner studio output via Silver Bullet has been strong — multiple partner titles have launched in 2026 covering softer maths models than the in-house catalogue. True new IP from the in-house team has been scarce, consistent with how most established studios now operate.

Classic Relax Gaming Slots Worth Playing

Money Train 2

The 2020 release that established the Money Train formula at UK casinos. 96.40% RTP, 50,000x max win, and the blueprint for every persistent-symbol bonus round that followed across the industry.

Temple Tumble Megaways

The 2019 temple-block demolition game that established Relax Gaming’s design identity outside the Money Train series. Still widely stocked at UK casinos in 2026 thanks to its 96.25% RTP and accessible maths.

Dead Man’s Trail

A 2021 Western-themed release with a collect-trail mechanic that predated many similar designs across the industry. High volatility, 10,000x max win, and one of the cleaner examples of Relax Gaming’s maths design outside the flagship franchises.

What to Check Before You Play

RTP Versions — Why the Same Game Pays Differently

Relax Gaming, like most major providers, releases in-house titles with multiple RTP configurations. Money Train 4 ships in 96.10%, 94.10%, and 92.10% versions, and UK operators choose which build to offer. Always open the in-game paytable before committing to a session and confirm the active RTP. The original Money Train shipped at 98.00%, but some operators stock reduced versions at 96% or 94% — on a title of that theoretical ceiling, that drop is genuinely significant over extended play. If an operator is running a reduced version, moving to a different casino is usually the right response.

Bankroll Planning by Volatility Tier

For extreme-volatility Relax Gaming slots like the Money Train series, Hellcatraz 2, and Beast Mode, a working guideline is 300–500 base-bet spins per session — enough to absorb extended dry stretches before reaching a bonus round. For high-volatility but softer titles like Temple Tumble Megaways or Iron Bank, 200 base-bet spins is usually adequate. Bonus Buy sessions require significantly larger reserves: Money Train 4’s buy costs around 500x the bet, and covering multiple dry buys requires a bankroll in the thousands of base bets.

Hit Frequency & Bonus Trigger Rates

Extreme-volatility Relax Gaming slots trigger their main bonus rounds roughly once every 200–400 base-game spins. Money Train 4 sits toward the higher end of that range, while Temple Tumble titles trigger noticeably more often thanks to their cascade-based bonus entry. Hit frequency in base play is generally low — these are games designed around the bonus round rather than steady base-game returns. Dream Drop jackpot triggers are genuinely random and not tied to feature activation; any spin at any stake can hit a tier, though higher stakes improve network-wide trigger probability.

Playing Relax Gaming Slots Responsibly

UKGC Licensing & GamStop

Relax Gaming holds UK Gambling Commission approval, and every UK casino carrying its content must itself be licensed by the Commission. All UKGC-licensed operators are required to participate in the GamStop self-exclusion scheme. If you are registered with GamStop, you cannot open or log into any UKGC-licensed casino for the duration of your self-exclusion period. Before depositing at a new site, confirm the UKGC licence number in the footer and cross-check it against the Commission’s public register.

Session Limits & Deposit Tools

Every UKGC-licensed casino must offer deposit limits, loss limits, session time alerts, and reality checks. These tools are accessible from the account menu and can be enabled in seconds. For extreme-volatility slots like the Money Train series, time-based session limits are particularly worth using — the bonus-round payoffs can make extended sessions feel faster than they actually are, and reality checks at 30-minute or hourly intervals help break the flow. Deposit limits set ahead of a session are the most effective preventative tool. Decreases take effect immediately, but increases require a cooling-off period before activation.

Support Resources

If gambling is starting to feel less enjoyable or harder to control, free 24/7 support is available from GamCare by phone, live chat, or online forum. GamCare also operates structured treatment programmes and can refer you to local face-to-face counselling services. Reaching out early — before control is fully lost — produces significantly better outcomes than waiting until the situation has escalated. Using the time-out tool in your casino account is a useful short-term step while considering next steps, and switching to softer content from studios like Play’n GO or Pragmatic Play can help shift away from extreme-variance sessions.
