Play’n GO: slots, grid mechanics and the Book of Dead studio
Play’n GO is a Swedish slot studio operating in 30+ regulated jurisdictions, best known for Book of Dead and for effectively inventing the grid slot. Around 400 titles, mostly slots with some table games, available through the IGP aggregator.
The studio
Who Play’n GO are
Play’n GO was founded in 2005 in Växjö, Sweden, with roots in game development reaching back to the late 1990s. It is now one of the largest independent slot studios in the industry, with a catalogue of roughly 400 titles and direct licences in more than thirty jurisdictions.
Book of Dead (2016) is the game that made the name global, and it is still one of the most-played online slots anywhere. But the more interesting technical story is the grid slot — Play’n GO shipped Energoonz in 2013 and then built the entire Reactoonz, Gemix, Moon Princess and Tome of Madness lineage on top of it.
The studio runs an unusually disciplined franchise system. Rich Wilde, Reactoonz, Rise of Olympus, Sweet Alchemy, the Joker series and licensed-music titles each have their own identity and their own sequels, which is why players search for Play’n GO games by series name rather than by studio.
Strategically, Play’n GO is a regulated-markets-only supplier — a positioning its commercial leadership states plainly. That narrows where it operates and raises what it costs to carry, but it also means the licence trail is unusually complete.

Play’n GO ships multiple RTP configurations per title and the operator selects which to run, so no single RTP figure applies across every casino carrying the game.
What makes it different
What Play’n GO is known for
One format the studio effectively created, one new mechanic from 2026, and a franchise discipline that is itself a competitive advantage.
Grid slots
The studio’s defining format and one it credibly pioneered. Equal-dimension grids — 5×5, 6×6, 7×7 — with cluster wins and cascades: winning clusters vanish, symbols drop in from above, and the chain can keep going. Started with Energoonz in 2013 and matured through Gemix, Reactoonz and Tome of Madness.
GO Guaranteed
Debuted 3 September 2026 with Infernal Trinity. A progression ladder of fixed guaranteed wins from 10x up to 100x the bet, and 120x in Ultra mode. The player climbs it by landing all three Tear Scatter colours in a single spin, and it resets when all three phoenix features fire together during Hold and Spin.
Series franchising
Rich Wilde, Reactoonz, Rise of Olympus, Sweet Alchemy, Legion Gold, the Joker series and licensed-music titles. Each runs to multiple sequels with a consistent identity, which is why players search the series name rather than browsing a provider filter.
Where it runs
Where Play’n GO games are available
Play’n GO has the broadest regulated footprint of any independent slot studio — over thirty jurisdictions, held as direct licences rather than through distribution.
Europe is the core: the UK, Sweden, Denmark, the Netherlands, Italy, Portugal, Switzerland, Greece, Belgium and Gibraltar. North America is the growth front — Ontario, Quebec, Alberta (licensed May 2026, live July 2026), Michigan, New Jersey, Pennsylvania, West Virginia, Connecticut, Delaware and Florida.
Latin America is expanding through Colombia and Argentina. The studio does not operate in unregulated markets by policy, so if your target market is grey, Play’n GO content will not be available there.

FAQ
Play’n GO — common questions
Video slots, grid slots and table games. The catalogue runs to roughly 400 titles. There is no live dealer, bingo or crash product — Play’n GO is a slots studio and has stayed one.
Book of Dead is the global headline title. Reactoonz, Moon Princess, Rise of Olympus, Fire Joker, Gemix, Legacy of Dead and Tome of Madness are the other names players search for directly. The newest release is Infernal Trinity (September 2026).
A slot built on an equal-dimension grid — 5×5, 6×6 or 7×7 — where wins come from clusters of matching symbols rather than paylines. Winning clusters disappear, symbols cascade down to fill the gaps, and the chain can continue. Play’n GO shipped the first one, Energoonz, in 2013.
A mechanic introduced in September 2026 with Infernal Trinity. It is a ladder of fixed guaranteed wins running from 10x to 100x the bet, climbed by landing all three Tear Scatter colours in one spin, and reset when all three phoenix features trigger together.
Extensively. Direct licences include Malta (MGA/B2B/225/2012), Gibraltar (RGL 131), the UK Gambling Commission, Greece, Denmark, Belgium, Alberta, Michigan, Connecticut, Delaware and Florida, plus certification in a further dozen European markets. The studio operates in regulated markets only as a matter of policy.
Around 400. The studio’s own materials quote both 350+ and 400+ in different places, so either is defensible — ask for the current machine-readable game list if you need an exact figure for a specific market.
Through an aggregator. Play’n GO content sits in the IGP catalogue with 150+ other studios on a single API and wallet. Note that availability is market-dependent, since the studio only supplies regulated jurisdictions.
