Provider
Endorphina
Endorphina is a game studio founded in 2012 in Prague, Czech Republic, by a team of local iGaming professionals. More than a decade later it has become one of Central and Eastern Europe's best-known exports to the global casino market. Its portfolio runs from classic joker-and-fruit reel sets to mythology, gothic horror, festive specials and crypto-inspired concepts. Titles such as Mystery of Eldorado, Satoshi's Secret, The Ninja and Minotaurus have built its reputation with players and operators. The studio focuses on slots and instant games, offers a unified progressive jackpot network called Clover Chance, and holds B2B licences from regulators including the Malta Gaming Authority. Its content reaches more than 54 jurisdictions. A shelf of industry awards, from SiGMA's Best Slots Provider of the Year in 2022 to AffPapa's Game Provider of the Year in 2025, shows that its standing has grown steadily over time.
History & Licenses: From Prague to a Multi-Regulator Footprint
Endorphina was founded in Prague in 2012, and the Czech capital is still its headquarters. Jan Urbanec leads the company as CEO. Regulated status has been central to its growth. In 2018 the Malta Gaming Authority issued it a Type 1 Critical Gaming Supply Licence (MGA/B2B/404/2017), which covers companies that supply core game software. Further approvals followed from Romania's National Gambling Office (ONJN) and Greece's Hellenic Gaming Commission. In 2026 the studio added a Gaming-Related Vendor Licence (Tier II) from the GCGRA in the UAE, extending its reach into a newly regulated Middle Eastern market.
Fairness, Testing and Information Security
Endorphina backs its licences with independent certification. Its software has been tested and certified by iTech Labs and GLI, two of the most widely recognised testing laboratories in the industry. They check that game outcomes and systems behave reliably and with integrity. The studio has also completed ISO/IEC 27001:2022 certification for information security management. This standard covers how a company protects data and infrastructure, not just how its games perform. For operators, it signals that the supplier's own processes meet an internationally audited benchmark. For players, it adds a further layer of assurance behind the games they see in a lobby.
Most Popular Endorphina Games
Endorphina's signature catalogue is broad. Mystery of Eldorado is arguably its flagship: it won Best Online Slot at the Login Casino Awards 2019. Satoshi's Secret brings a crypto-inspired concept to the reels. The Ninja and Golden Ox draw on East Asian imagery, while Minotaurus turns to Greek myth. Kamchatka takes its name from the remote Russian peninsula. Hell Hot 100, Joker Stoker and Lucky Streak 3 continue the studio's classic-style lineage. Twerk shows its willingness to be playful. Book of Santa gives the popular book-slot format a festive twist. Chances of Angels and The Vampires round out a list that spans the celestial and the gothic.
Design Identity: A Studio of Many Moods
Endorphina does not have one house style. Its range is its identity. On one side are retro-leaning games like Joker Stoker, Hell Hot 100 and the Lucky Streak series. These appeal to players who like fast, familiar reel play without heavy narrative. On the other side are story-driven worlds: Mystery of Eldorado's lost-city adventure, the dark romance of The Vampires, the martial mood of The Ninja. Between them sit novelty concepts such as Twerk and Satoshi's Secret, which show a studio unafraid of offbeat themes. The result is a portfolio that lets an operator cover several player types from one supplier.
Clover Chance: A Unified Progressive Jackpot Network
One of Endorphina's more strategic assets is Clover Chance, a unified progressive jackpot network that runs across its portfolio. Linking jackpots across multiple titles gives the prize pool more momentum than any single game could build alone. It also adds a layer of anticipation to every spin, whichever eligible slot a player picks. For operators, a network jackpot works as a retention tool: players stay within the studio's catalogue while chasing a shared prize. It also gives the portfolio a common thread that stand-alone releases lack.
Innovation: Joker Ra and AI-Generated Art
In 2023 Endorphina released Joker Ra, described as one of the first slots to make extensive use of AI-generated graphics. The release was notable because visual production is one of the most resource-intensive parts of slot development. Experimenting with AI imagery at that stage put the studio among the early movers in a technique the wider industry was only starting to test. Joker Ra also fits Endorphina's pattern of combining a familiar motif, here the joker, with a fresh setting and a new production method.
Portfolio Across Verticals: Slots and Instant Games
Endorphina concentrates on two product categories: video slots and instant games. Slots are the core of the offer, from classic-style reel sets to feature-rich themed releases. Instant games cover the quick-result formats that suit short sessions and mobile play. This tight focus is deliberate. Rather than spreading into many verticals, Endorphina puts its development effort into reel-based and instant content, and pairs that catalogue with its own jackpot layer.
Technology & Distribution
Operators integrate Endorphina content through a modern API connected to a proprietary backend that handles day-to-day game operations. Owning the backend gives the studio direct control over how its games are delivered, monitored and managed once they are live. It does not have to rely entirely on third-party infrastructure. This technical base, together with its ISO/IEC 27001:2022-certified security management, supports the studio's expansion into more than 54 jurisdictions. It also lets new markets be switched on without rebuilding the product for each one.
Awards & Industry Reputation
Endorphina's awards cover much of its history. Slots Guide named it Best Online Slot Developer of the Year in 2015. Mystery of Eldorado took Best Online Slot at the Login Casino Awards 2019. The studio had a strong 2022: Best Slots Provider of the Year at the SiGMA Awards, Developer of the Year at the SPiCE India Awards, and Rising Star of the Baltics in Online Casino Technologies at the BSG Awards. It has also been named Best Game Development Studio at the GamingTech CEE Awards and Best Online Casino Provider in CEE at the Gaming Tech Award 2024. In 2025 it won Game Provider of the Year at the AffPapa iGaming Awards.
