Relax Gaming built the most extreme volatility slot franchise in the industry with Money Train — three sequels, each pushing the max win ceiling higher than the last. Beyond the train, their catalogue spans treasure hunts, fantasy battles, and jackpot networks through the Dream Drop platform. We’ve ranked their 6 best slots of 2026, scored on bonus mechanics, RTP, max win potential, and session quality.
Relax Gaming launched in Malta in 2010 and spent years building a B2B aggregation platform before their in-house slots division put them firmly on the map. The tipping point was Money Train 2 in 2021 — a maximum 50,000x win mechanic that rewrote expectations for what a bonus round could deliver. The studio was acquired by Kindred Group in 2021 for €320M, though it continues to operate independently. Our full Relax Gaming RTP list reveals how their titles perform across operators.
The Money Train series has since become one of the most-played slot franchises in the world. Money Train 3 raised the ceiling to 100,000x, and Money Train 4 introduced split multiplier mechanics that make every free spin a potential life-changer. Beyond the franchise, Treasure Tumble showcases Relax's design range — a Megaways-influenced cascading reels title with a 7,776-way payline grid and 10,000x potential. Their Dream Drop jackpot network pays progressives across hundreds of participating casinos simultaneously.
For Canadian players, Relax Gaming titles are widely available on both AGCO-licensed Ontario platforms and international crypto casinos. The Money Train series is particularly popular on Gamdom and Rolling Slots, where stake limits reach $1,000 CAD per spin. Dream Drop jackpot titles are worth targeting during peak Canadian evening hours — the network pool grows fastest when all participating casinos are busy, and several Canadian players have landed five-figure CAD wins on the jackpot tier.

These are among the most extreme slots ever produced. Session budgets of 300–500x stake are the minimum recommendation. The Hold & Win bonus is infrequent — most sessions will end in loss. When it does trigger with favourable symbol placement, the output can be extraordinary. Money Train 4’s 150,000x ceiling makes it the highest-potential regular slot currently available.
Still high variance, but manageable compared to the Money Train titles. Treasure Tumble’s cascade mechanic produces regular small wins interspersed with periodic large multiplier chains. Arena of Fortune and Cod of Thunder Dream Drop offer more conventional session profiles.
