Relax Gaming Slots

Relax Gaming has been the Malta-based reference studio for modern big-win slots since 2010. Focused on dense bonus rounds and record max wins, Relax Gaming established itself on the 2018+ slot scene with the cult Money Train franchise and Hellcatraz. Roughly 80 slots in the catalogue, above-average quality overall.

The absolute signature slot: Money Train 4 (September 2023). A 6x6 Scatter Pays format, 96.1% RTP, max win 150,000× — the outright market record across every provider, ahead of Nolimit's Tombstone R.I.P. (advertised at 300,000× but under 150,000× in practice across tested sessions). The Money Cart mechanic (triggered by 3+ scatters) runs with 20+ persistent modifier symbols plus an Upgrader that transforms symbols. It's the slot with the highest theoretical mathematical potential in our selection.

Relax's signature identity: genuinely dense bonus rounds. The Money Cart mechanic has become a market reference — triggered by 3+ scatters, it runs a bonus mode with 20+ persistent modifier symbols (Necromancer, Sniper, Reset, Persistent Sniper, Collector, Payer, Upgrader, Hat Switcher, Boss...). It's not a simple Free Spins round — it's a full standalone game with its own game design.

The Money Train saga: Money Train (2019, 20,000× max) → Money Train 2 (2020, 50,000× max) → Money Train 3 (2022, 100,000× max) → Money Train 4 (2023, 150,000× max). A clean linear progression in max wins. Money Train 2 remains the most played for its RTP/max-win balance.

Hellcatraz (June 2020) is the portfolio's second best-seller. A 6x6 cluster pays format, 96.46% RTP, max win 51,840×. Unique mechanic: countdown mystery symbols (each mystery symbol carries a counter that ticks down; at 0 it transforms into a random high-pay symbol). Combined with cluster pays, it produces genuinely dense sessions.

Relax's RTP — honest. The studio generally sticks to its official RTP figures (96-96.46%). Downgraded builds are rare (unlike Pragmatic Play or Play'n GO). Money Train 4: 96.1%. Hellcatraz: 96.46%. Money Train 2: 96.4%. That's one of the structural arguments for favouring Relax over studios with common downgraded builds.

An innovative bonus buy: Money Train 4 offers two Buy tiers — 100x stake (standard, classic Money Cart access) or 500x stake (a persistent-symbol version pre-loaded for a bigger potential boost). That's rare on the market and lets high-bankroll players target the 150,000× max win.

For players: Relax Gaming is very well integrated across the leading crypto and anonymous casinos in the BetsRank top list (SpinAura, BetRiviera, SlotLair). ⚠️ No online casino is ANJ-licensed in France: the ANJ licenses sports betting, horse racing and poker only, so it cannot step in if a dispute arises.
