148 free demo slots from Onlyplay
OnlyPlay makes more sense as a studio once you stop thinking of them as a slot provider. The Lithuanian company spent over a decade building games for other businesses before launching its own brand in 2020, and that history shows. Their real identity lives in crash games and a patented tap-based format called TapGames - the slots you see here arrived later, and they play like a different studio made them.

OnlyPlay's origin explains a lot about the catalog's uneven personality. The team started in Vilnius in 2007 as a contract development shop, building lottery games and instant-win products for other companies. By 2013 they were coding instant-win titles for Lithuania's national lottery. In 2016 - years before most iGaming studios discovered crypto - they shipped a game on Ethereum. CEO Christina Muratkina joined around 2011 as a programmer, which partly explains why the studio's marketing stays quiet while the technical output stays ambitious.
The rebrand to a standalone provider happened in June 2020. Five years later, the catalog has grown past 140 titles distributed through 2,500 operators and aggregators like SoftSwiss, QTech, and EveryMatrix. The company's identity still splits cleanly between its original strengths (crash games, instant wins, experimental formats) and the conventional video slots it started producing after 2023 to fill operator lobbies.
F777 Fighter put OnlyPlay on the B2B map. A dual-bet crash game with progressive jackpots and 97% RTP, it found traction on crypto-friendly platforms and spawned a family of themed variants: CosmoX, GoalX, ScoreX, CricX. The crash lineup runs at a consistent 97% RTP with provably fair verification - solid math for the format, and the studio built ultra-lightweight sub-1MB versions of these games specifically for African markets with limited connectivity.
Then came TapGames, a patented mechanic that drops reels entirely. Piggy Tap has players tapping to smash a piggy bank in a shared multiplayer environment, splitting the prize pool among participants. The format earned SlotsWise Award nominations in 2025, and the patent gives OnlyPlay a mechanical moat no other provider can legally copy. Whether tap-based gameplay keeps players coming back long-term remains an open question, but the idea itself is more inventive than what 90% of small providers produce.
The video slots in this catalog - Zeus Sky, Valentine Storm, Wild West Jackpot, Lucky Ferret - arrived as part of a push into conventional slot territory. They use familiar frameworks: Hold & Win, multiplier reels, cascading wins, fixed jackpot tiers. Competent execution, clean mobile interfaces, decent RTPs. Nothing in these slots signals the same inventiveness that built TapGames or the crash lineup. The gap between OnlyPlay's experimental formats and their slot output is the widest disconnect in the portfolio.
OnlyPlay holds a Curacao gaming license with RNG certifications from iTech Labs and BMM Testlabs. MGA and UKGC applications have been mentioned in company communications over the past two years. Neither license has materialized.
This matters for two reasons. Curacao-only providers are excluded from UK-regulated casinos, which removes them from the largest English-speaking gambling market and the streamer/forum ecosystem that drives organic player awareness. And operators in stricter jurisdictions - Malta, Sweden, Denmark, the Netherlands - either can't or won't integrate Curacao-only content. Five years into their branded existence, the licensing gap remains the single biggest brake on growth. The B2B aggregator network compensates for distribution reach, but it doesn't solve the regulatory credibility question.
The practical result is that OnlyPlay thrives in crypto casinos, Latin American markets (they built Brazil-targeted titles like Caramelo Jackpot), and African operators - segments where Curacao licensing is standard and connectivity-optimized products have real value. The player communities around these markets don't overlap much with English-language forums, which is why almost nobody on Reddit or streaming platforms talks about OnlyPlay despite the studio serving thousands of operators.
Of the five games here, Lucky Ferret plays like the studio had something to prove. High volatility, 96.5% RTP, cascading reels with Free Spins, Mirror and Coin symbols, and a max win above 20,000x. For a provider whose other slots cap between 2,944x and 10,232x, that ceiling signals a different design ambition - closer to what Hacksaw or Push Gaming would attempt.
Wild West Jackpot takes a more interesting structural approach. A sixth Multiplier Reel applies x1 through x9 to every win on the spin, layered over a five-tier fixed jackpot system. At 96.06% RTP and medium volatility with a 10,232x cap, it's built for session play rather than a jackpot chase.
Zeus Sky: Hold & Win runs the most conservative math in the catalog. A 3x3 grid, medium volatility, 2,944x ceiling. Functional, but the Hold & Win format has been executed more aggressively by a dozen other providers with deeper multiplier stacking and higher payout potential.
ChiX operates on crash game math at 97% RTP. It shares the page with four video slots, but comparing it to them makes about as much sense as comparing blackjack to a slot machine. The session dynamics, house edge model, and player interaction are fundamentally different. Players who enjoy crash games should try it on those terms rather than expecting slot-style gameplay.
Valentine Storm is the newest release and the hardest to assess. Medium volatility at 95.66% RTP with an 8,000x cap. The structure suggests a Hold & Win or momentum-based format in holiday packaging. February seasonal releases from any studio tend to be short-shelf-life products, and at 95.66% it sits at the lower end of what the rest of the catalog offers.
