What is Snowborn Games known for?
Snowborn Games is a slot studio with offices in Stockholm and Helsinki. It is best known for Masters of Valhalla and Masters of Olympus, two 5x4 slots with 1,024 ways and a top win of 20,000x, along with Pile 'Em Up and the Hyper Frames feature. Its games reach casinos through Games Global, the network that took over Microgaming's content in 2022.

What 86.89% Means in Snowborn Games Casinos
Most Nordic slot studios head straight for the European market. Snowborn took the scenic route. In May 2018 the Asian distributor QTech Games was reported to have bought a controlling stake in Snowborn Games AB, then a young Stockholm developer, and every new Snowborn slot was to be exclusive to QTech’s clients.
The first result was The Vault, a diamond heist slot with Paris landmarks behind the reels, which QTech unveiled at an after party during the ASEAN Gaming Summit in Manila in March 2019. A year later the picture had changed. In April 2020 Microgaming signed an exclusive supply deal with Snowborn, and The Vault went live for Microgaming’s operators on 28 April as the studio’s debut on that network, with five reels, 20 lines, respins, stacked wilds and free spins.
CEO Björn Zethraeus has said the company dates back to 2017 and became a pure game studio in 2020, after years spent building its own platform and game framework. That explains why SlotCatalog gives 2020 as the starting year, and that in house framework still powers every release. When Microgaming’s content business became Games Global in 2022, Snowborn’s games moved with it.
If you know one Snowborn title, it is probably a Masters game. These are the slots that put the studio on the map, and Zethraeus has called the first of them a major hit.
Released exclusively in February 2022 and to the wider market a month later, Masters of Valhalla puts Norse gods on 5×4 reels with 1,024 ways. A Berserk Booster meter fills as you play, the Wild God Respin gives the base game some bite, and the Valhalla Bonus is where the 20,000x top win lives. SlotCatalog rates it high volatility.
The Greek follow up arrived in January 2023 with the same 5×4 grid, the same 1,024 ways and the same 20,000x ceiling, plus a buy feature, sticky wilds and moving wilds. Side by side, the two games show what the studio means when it talks about pairing an engaging base game with volatile bonus features while staying away from slots where everything hangs on the bonus round.
Newer Snowborn slots lean on named mechanics that come back across several games, and Hyper Frames is the one worth understanding first.
It first appeared in Zeus Hyper Frames, released in July 2025 on 5×3 reels with 243 ways. Bonus symbols leave a bronze frame behind, the frame can upgrade to silver and then to gold, and a gold frame reveals a prize of 7x to 20x or one of the fixed jackpots. Six or more bonus symbols start the bonus game. SlotCatalog lists low volatility and a top win of 6,200x, so this is a gentler ride than the Masters games. Hyper Frames Poseidon has since brought the idea back with a different god.
Cash Flip is the other recurring trick, with bonus symbols that flip over to raise their value, seen in Cash Flip Medusa and Cash Flip Medusa Gold. Then there is Pile ‘Em Up from 2022, a retro cash collect game with a multiplier that keeps climbing. The studio’s own game list also shows series such as Massive Gold, Lucky Lemons and the Tippy games, so a sequel to the one you like is rarely far away.
Here are the figures SlotCatalog lists for five Snowborn slots, with the top win for The Vault taken from its 2020 launch news. They show how differently the games play once you look past the art.
| Slot | Released | Layout | Volatility | Top win |
|---|---|---|---|---|
| The Vault | April 2020 | 5×3, 20 lines | High | 5,000x |
| Masters of Valhalla | February 2022 | 5×4, 1,024 ways | High | 20,000x |
| Pile ‘Em Up | May 2022 | 5×3, 20 lines | High | 7,500x |
| Masters of Olympus | January 2023 | 5×4, 1,024 ways | High | 20,000x |
| Zeus Hyper Frames | July 2025 | 5×3, 243 ways | Low | 6,200x |
Four of the five are rated high volatility, so expect quiet spells between the bigger hits. SlotCatalog counted 44 Snowborn games when we checked, and new titles were still arriving in 2026.
Here is a number worth remembering. According to SlotCatalog, Masters of Olympus has a top RTP of 96.01%, but operators can choose to run it at 94.02%, 92.03% or even 86.89%. Same reels, same gods, same bonus, and a very different long term return.
Masters of Valhalla and Pile ‘Em Up are listed with RTP ranges too. The casino picks the setting, not the studio, so two Snowborn Games casinos can offer the identical slot with different returns. Nothing on the lobby thumbnail tells you which one you have opened. The info screen does, so check it before you play, and if the figure sits well below 96%, try the same game at another casino from the list.
The list at the top of this page shows the open casinos in our database that carry Snowborn Games, with closed and blacklisted sites left out. A place on that list tells you the slots are in the lobby, nothing more.
We found no gambling licence in Snowborn’s own name. The studio’s own site says its games reach operators across the Games Global network through the Quickfire distribution platform, so the licence that matters to you is the casino’s. Make sure it covers the country you live in, and if online casinos are not legal where you are, do not play. Read the withdrawal limits and processing times in our review, and check the RTP version as described above.
If you take a bonus, read the game weighting in the terms. Many casinos count slots in full, but some exclude high volatility titles or games with a buy feature, and that can make a bonus far harder to clear at Snowborn Games casinos. If the Nordic gods are not for you, our overview of game providers has plenty of other studios to try.
Snowborn Games has offices in Stockholm and Helsinki. It started out as Snowborn Games AB, a Stockholm developer, and its CEO dates the company back to 2017.
Games Global. Snowborn signed an exclusive supply deal with Microgaming in 2020, and its slots now reach the casinos on the Games Global network, so that is how most Snowborn Games casinos get them.
Public sources do not make that clear today. QTech Games was reported to have bought a controlling stake in 2018, but we found no recent source confirming the current owner, so we will not guess.
Masters of Valhalla and Masters of Olympus, followed by Pile ‘Em Up, Zeus Hyper Frames and the debut slot The Vault. The Cash Flip, Massive Gold and Lucky Lemons series also turn up in many lobbies.
It depends on the version. Several Snowborn slots come with RTP ranges, and Masters of Olympus runs from 96.01% down to 86.89% according to SlotCatalog. Open the info screen at the Snowborn Games casinos you use to see the figure you are actually getting.
Yes. SlotCatalog lists 2026 releases such as Triple Train Express and Cash Flip Medusa Gold, and the studio’s site was already showing Coin Blossom as its next game when we checked.
