Free Relax Gaming Games & Slots

Founded in March 2010 by Patrik Österåker and Jani Tekoniemi, Relax Gaming began as an aggregation platform before building in-house games from 2018 onward. The studio is now owned by Kindred Group, which acquired full control in October 2021, though Relax retains its own board and management team. It is licensed by the Gambling Commission and regulated across multiple jurisdictions. Offices span Malta, Estonia, Serbia, Sweden, Finland and Gibraltar, with game studios based in Belgrade, Novi Sad, Malmö and Stockholm.

The aggregation side of the business connects over 7,000 games from hand-picked partner studios to operators worldwide. On the content side, Relax has earned Casino/Slot Developer of the Year at the SBC Awards, Best Mobile Gaming Software Provider at the EGR B2B Awards, and GGA Product Launch of the Year for Dream Drop Jackpots. Most of the own-game catalogue falls into the video slots category, though the studio also offers poker and bingo products.

Themes and Styles

Relax Gaming covers a wide thematic range across its own titles. The Money Train series leans into a Wild West heist setting with persistent symbols and extreme volatility, while Iron Bank shifts the action to a high-security vault theme with expanding wilds and mystery symbols. The Temple Tumble line builds on adventure archaeology, using cascading reels and multiplying free spins to create a momentum-driven feel.

On the quieter end, Epic Joker and Powerspin deliver retro fruit-machine formats with a modern edge. Book of 99 draws on Egyptian mythology with its symbol-collection free spins mechanic, while Marching Legions brings Roman history to a 243-ways grid. The studio’s 2026 pipeline introduces Kraken’s Cove (7×7 cluster pays), Purrrminator (reverse avalanche) and Olympus 7’s Dream Drop, which packs six mini slots into a single Greek mythology framework. Titles carrying the Dream Drop badge also feed into the studio’s progressive jackpot slots network.

Key Mechanics and Features

Dream Drop Jackpots are the studio’s marquee feature, launched in May 2022 and now spanning 40+ titles across Relax and its Silver Bullet partners. The network carries five progressive tiers plus three guaranteed daily jackpots, with the Mega tier seeded up to €2 million. A random trigger during any spin can launch the jackpot entry round, where landing six Dream Drop symbols determines the prize tier. The network has created over 20 millionaires since launch.

The Money Cart bonus, signature to the Money Train franchise, uses a hold-and-respin grid populated by Payer, Collector and Sniper symbols. Each symbol type interacts differently — Payers add value, Collectors gather from other positions, and Snipers target specific cells. These persistent interactions can compound across respins, which is how Money Train 4 reaches its 100,000× max win ceiling.

The Tumble mechanic underpins the Temple Tumble series and several newer releases. Winning symbols are removed after each evaluation, allowing fresh symbols to fall into place. When paired with a non-resetting free-spins multiplier, this cascade structure can generate escalating win chains. Relax also uses expanding symbols (Book of 99), mystery symbols (Iron Bank, Hellcatraz) and cluster pays in newer titles like Pharaoh’s Last Wish. Several games support Megaways games formats, including Temple Tumble Megaways with up to 46,656 ways to win.

RTP and Payout Overview

Relax Gaming’s catalogue includes some of the highest-RTP slots available at licensed casinos. Book of 99 sits at the very top with a 99% return to player — just 1% house edge — making it a standout choice for value-focused sessions. The table below covers a cross-section of popular titles, from high-RTP classics to high volatility and extreme-volatility flagships. Check each game’s paytable for the exact return to player figure, as some titles offer multiple RTP tiers depending on whether the ante bet or bonus buy option is active.

Mobile and Free Play

Every Relax Gaming title runs on HTML5 and loads directly in mobile and desktop browsers without a download. The studio optimises its games for touchscreen input, and the responsive layouts adjust smoothly across screen sizes. Free demo mode is available on most titles, which is a practical way to learn how to play slots and explore mechanics like the Money Cart bonus or Dream Drop entry round before placing real bets.

Tips for Playing Relax Gaming Slots

We recommend starting with Book of 99 if you want extended play at the lowest possible house edge — its 99% RTP means the theoretical return is among the best available in any online slot. For players drawn to high-volatility action, the Money Train series offers extreme win ceilings but demands patience; dry spells between feature triggers can be long, so it pays to manage your bankroll accordingly.

Dream Drop jackpots fire on a random trigger that is independent of bet size, game selection or session length. No strategy can force the entry round — it is purely a matter of chance. Use demo mode to familiarise yourself with each game’s base game rhythm, scatter patterns and bonus round structure before committing real stakes.
