RubyPlay: gems, sevens and a link feature that sells
RubyPlay is one of the steadier mid-tier slot studios in the market. It launched in 2017, set up shop in Malta with development roots in Kyiv, and built a catalogue around a small number of ideas done well: glossy gem and fruit themes, a hold-and-collect link feature, and math that operators can tune. It is not the loudest studio in the lobby, but its games keep showing up. Here is who they are and what to check before you play them.
Who they are
RubyPlay emerged in 2017 as a development studio with a team that, by its own account, carries a couple of decades of combined iGaming experience. The company is structured under NSYNC Developments and opened offices in Malta as it scaled, adding the Malta Gaming Authority licence and Romania's ONJN approval, which are the credentials that let it supply regulated markets rather than only offshore ones. That licensing matters for a B2B supplier: it is the difference between a studio a serious operator can integrate and one it cannot. RubyPlay distributes through the major aggregation platforms, so its games reach a wide spread of casinos without the studio needing a direct deal with each one.
The games and the Link It Up feature
RubyPlay's house style is clean and commercial: bright gem clusters, classic fruit-and-seven symbols, and the occasional themed adventure. Its signature mechanic is Link It Up, a hold-and-win style feature where collected coins lock in place and respin for a shot at fixed and progressive jackpots, the same template Pragmatic and others made popular. Diamond Explosion 7s is the studio's calling card, and to play Diamond Explosion 7s is to see the formula at work: a familiar classic-slot look bolted to a modern link-and-collect bonus, with extras like a Jackpot Pick round. Immortal Ways Diamonds and Mayan Cache show the same instincts on a ways-to-win and an adventure theme, while Book of Riches Deluxe nods to the genre's evergreen book mechanic. The studio favours a curated release pace over flooding the market, which keeps the quality even. Its games sit alongside other feature-led mid-tier studios such as Booming Games and Spinomenal in most lobbies.
What to check before you play
RubyPlay ships games in more than one RTP version, which is normal for the industry but worth naming: the same title can pay a different long-run percentage from one casino to the next, so check the figure on the info screen the way our RTP guide recommends. Volatility varies across the catalogue, with the link-and-jackpot titles sitting on the higher-variance end, so read our volatility guide and stake to match. The link feature and progressive jackpots are designed to keep you spinning toward a big result that rarely lands, so set a budget before you start and use our responsible gambling tools to hold it. As always a good supplier does not vouch for a weak operator, so vet the casino itself using how to choose a casino. If the supply side interests you, our cornerstone on how to start an online casino explains where a studio like RubyPlay fits in an operator's content mix.
The verdict
Strengths: a tidy, commercial catalogue, a proven link-and-collect feature, proper MGA and ONJN licensing, and wide distribution through the aggregators. Weaknesses: the studio breaks little new ground, leaning on themes and mechanics the market already knows, and the jackpot titles carry the usual high variance. RubyPlay is a reliable mid-tier supplier whose games are easy to recommend to players who like polished gem and classic slots without surprises.
