About Gamzix
March 2020. The world had just shut down, borders were closing, and most businesses were bracing for the worst. Gamzix chose that precise moment to open. Founded in Tallinn, Estonia, during the first weeks of the Covid-19 pandemic, the studio built its proprietary game engine within five months of its doors opening, received RNG certification from iTech Labs in June 2020, and shipped its debut title Joker Splash the same month. It was an unlikely start. It also turned out to be a remarkably effective one.
Led by CEO Aleksandr Kosohov and operating across offices in Tallinn, Kyiv, and Cyprus with a team of between 51 and 200 people, Gamzix describes itself as a full-cycle slot provider, meaning it handles everything in-house from mathematics and mechanics through to animation, audio, and promotional tooling. That last part is more significant than it might first appear. The studio does not just hand over games and walk away. It gives operators access to a full suite of promotional tools including custom jackpots, slot tournaments, free rounds, and monthly in-house campaigns, all designed to slot neatly into existing casino infrastructure via API. It is a commercially thoughtful approach that has helped the studio land partnerships with over 2,000 casino operators globally.
The award recognition came quickly. SIGMA Industry Rising Star of the Year in 2022. New Casino Game of the Year at SIGMA in 2023. Best Rising Star in Gaming at MiGEA in 2025. A nomination for Game Feature of the Year at the CasinoBeats Game Developer Awards for Coin Win: Hold the Spin. Best Game Soundtrack for Book of Zulu at the SiGMA Euro-Med Awards, a win that reflects something genuinely unusual about how Gamzix operates: their audio team takes the music from their games and releases it as standalone albums on Spotify, Apple Music, and YouTube under the Gamzix Soundverse banner. The idea that a slot studio’s soundtracks are worth listening to away from the screen is a bold position to take, and it says something about how seriously the studio approaches the craft side of what it builds.
The Hold the Spin mechanic is the engine of the catalogue. It is not unique to Gamzix, but they have built more titles around it, refined it more deliberately, and extended it in more directions than almost any other studio. The concept is a respin system triggered when a minimum number of coin symbols land on the reels simultaneously. Those coins lock in place, respins begin, and each new coin that lands resets the counter to three. Fixed jackpots sit above the grid, and the full collection fills the board for the maximum payout. Gamzix has deployed this mechanic across dozens of variants including Coin Win, Sticky Coin, Tiger Pot, Spooky Coin, Samba Stars, Buffalo Coin, Buffalo Ice, Egypt Sphere, Patrick’s Luck, Japanese Coin, Sunny Coin, and the 3×3, 3×5, and 5×3 stripped-back versions for players who want the mechanic without the surrounding complexity.
Beyond Hold the Spin, the slot game studio makes a genuinely wide range of slot formats. Book of Zulu brought an African savannah theme to the book genre with an Extra Bet feature that guarantees a Wild Scatter on every spin for 2.5x the stake and an in-game soundtrack featuring real elephant calls recorded at Dubai Zoo. Gold Mania sits at the top of the portfolio in terms of raw win potential, delivering a 25,000x maximum win and an RTP of up to 97% through Sticky Wilds, Sticky Multiplier Wilds, and Unlimited Free Spins across a 5×3 grid with 10 paylines. Rich Granny, one of the studio’s more personality-driven releases, features random multipliers, wilds, and a Granny’s Letters bonus game built around a theme that manages to be both charming and genuinely feature-rich. The Chilli Fruits series, Bonanza Donut, 9 Jalapenos, and Jack O’Wild round out a catalogue of over 70 titles spanning fruit machines, book slots, Hold the Spin variants, jungle adventures, crash games, and more.
RTPs across the portfolio cluster around 96%, with Gold Mania pushing to 97% and Buffalo Coin and Buffalo Ice leading the active slots at 96.32%. Volatility spans medium through high across most titles, with max wins typically sitting between 2,000x and 10,000x, and Gold Mania’s 25,000x standing as an outlier at the ceiling. Bonus buy options are available across the majority of the range.
“Gamzix are one of those studios that keeps growing on you the more time you spend in the catalogue. The Hold the Spin mechanic is executed really well across all their variants and Gold Mania in particular is a seriously strong slot. Book of Zulu is a proper standout too. Consistent, well-crafted games from a studio that clearly takes audio and visual quality as seriously as the maths.” Mark, Content Editor
“Really enjoy the Gamzix slots. The Hold the Spin games have this brilliant rhythm to them where you’re just constantly watching those coins land. Tiger Pot is one of my favourites and Gold Mania when it goes off is incredible. Solid studio, good RTPs, nothing feels cheaply made.” Aisley, Slot Streamer
Gamzix Slot Game Reviews
FAQs for Gamzix
-
Founded during a global pandemic. How did Gamzix actually pull that off?
The studio was incorporated in Tallinn in March 2020, built its proprietary game engine in five months, received iTech Labs RNG certification in June 2020, and shipped its first title the same month. The compressed timeline was deliberate. CEO Aleksandr Kosohov built a small expert team and moved fast rather than waiting for conditions to improve. -
What is Hold the Spin and why does Gamzix use it so much?
Hold the Spin is a respin mechanic triggered when a set number of coin symbols land simultaneously. Those coins lock, respins begin at three, and each new coin resets the counter. Fixed jackpots at the Bronze, Silver, Gold, and Platinum level sit above the grid, with the top prize awarded for filling the board. Gamzix has refined and extended this system across over 20 variants, from full-featured releases like Tiger Pot and Spooky Coin to minimalist 3×3 versions stripped back to the core mechanics. -
What is the highest paying Gamzix slot?
Gold Mania. It carries an RTP of up to 97%, high volatility, and a maximum win of 25,000x, the highest ceiling in the entire catalogue. The game runs on a 5×3 grid with 10 paylines and three distinct bonus modes including Sticky Wilds, Sticky Multiplier Wilds, and Unlimited Free Spins. -
What is Gamzix Soundverse?
It is the studio’s standalone music project, releasing the in-game soundtracks from their slots as full albums on Spotify, Apple Music, and YouTube. The idea that a slot studio’s audio is worth listening to outside the game is an unusual position in the industry and reflects how seriously Gamzix takes sound design as a core element of every release rather than a background detail. -
What promotional tools do Gamzix offer operators?
A full suite including custom jackpots, tournaments, free rounds, monthly in-house campaigns, and the Spin-o-Mania promotional tool, all integrated via API and designed to work across the entire game catalogue. It is one of the reasons the studio has grown to over 2,000 operator partnerships despite being relatively young. -
How big is the catalogue and how quickly is it growing?
Over 70 titles at the time of writing, with roughly one new release per month since launch. The range spans Hold the Spin variants, book slots, fruit machines, crash games, and standalone themed releases. All games are built in HTML5, fully optimised for mobile and desktop, and available across regulated markets in Europe, Latin America, Asia, Africa, and Canada.
