Silverback Gaming
Silverback Gaming is a Bulgaria-based slot studio licensed by the UK Gambling Commission, known for Aztec Luck, Mystery Stacks and Golden Calaveras, and owned by GAN Limited since 2021.
Its portfolio is small and distributed mainly through Relax Gaming's Silver Bullet programme, which suits players who want a boutique studio backed by a named regulator rather than a large, all-purpose catalogue.

Silverback Gaming Casinos — Games, Fairness and Where to Play
Silverback Gaming is a slot studio founded in 2019 and registered in Bulgaria, holding a license from the UK Gambling Commission (UKGC) and serving players across the United Kingdom, Bulgaria and wider Europe. Its catalogue is compact and built around a handful of named titles — Aztec Luck, Mystery Stacks and Golden Calaveras — distributed to operators mainly through Relax Gaming's Silver Bullet programme rather than through a broad direct rollout.
Who Is Silverback Gaming
Silverback Gaming is headquartered in Sofia, Bulgaria, and was founded in 2019 under Raph Di Guisto, named as Founder & CEO of the studio at the time of its 2022 distribution agreement with Relax Gaming. PitchBook's company profile lists the studio at 8 employees, a figure that reflects a historical snapshot of a small, focused development team rather than a current 2026 headcount.
GAN Limited acquired Silverback Gaming along with exclusive rights to distribute its game portfolio, a deal completed on December 9, 2021. GAN Limited itself became a subsidiary of SEGA SAMMY CREATION on May 27, 2025, which places Silverback Gaming's output inside a larger corporate structure than the studio's own small headcount would suggest.
Games and Signature Mechanics
Silverback Gaming's publicly named releases are Aztec Luck, Mystery Stacks and Golden Calaveras — a short list that reflects the studio's scale rather than a gap in this catalogue. Aztec Luck was shortlisted in the Slots Studio Debut category of the 2021 CasinoBeats Game Developer Awards, an early signal of design recognition for the studio's first wave of titles. Golden Calaveras reached operators through Relax Gaming's Silver Bullet distribution channel, the same route used for the rest of the portfolio.
Because Silverback Gaming operates with a small team and distributes through a partner programme rather than direct market-wide launches, its visible catalogue stays narrow compared with larger studios in this hub. That is a function of the studio's size and distribution model, not a missing entry: a niche developer with eight staff on record and one distribution partner will naturally publish fewer titles than a studio releasing dozens of slots a year.
RTP, Volatility and Fairness
Return to Player (RTP) is a theoretical figure calculated over a very large number of spins — it describes what a game returns on average across millions of rounds, not what any single session will pay out. Volatility describes how that return is distributed: how often wins land and how large they tend to be. Silverback Gaming does not publish per-game RTP or volatility figures in the material available here, so the honest position is to judge the studio by its licensing rather than by invented percentages.
Silverback Gaming's ownership changed twice inside four years: GAN Limited completed its acquisition of the studio on December 9, 2021, and GAN itself became a subsidiary of SEGA SAMMY CREATION on May 27, 2025 — two ownership changes that sit behind a studio whose day-to-day output has stayed small.
Where to Play Silverback Gaming Games
Silverback Gaming's titles are listed at the casinos shown in the selection above this text, all drawn from operators licensed under Tobique, Anjouan or Curaçao registers. Four of the four casinos in this selection hold a Tobique license, three of the four hold an Anjouan license and three hold a Curaçao license, so a reader who wants a specific regulator has more than one option among Silverback Gaming's listed operators. Because the studio's portfolio is small, a general casino directory search is less useful here than checking the provider list on the operator itself before depositing.
- Provider availability — confirm Silverback Gaming titles appear in the casino's own lobby search, not just in its licensing history.
- Casino license — Tobique, Anjouan and Curaçao registers all appear among the operators carrying this studio, per our records.
- Minimum deposit — the casinos in this selection typically set a minimum deposit of 20 EUR/USD, per our records.
- Payout window — half of these casinos process withdrawals in under 24 hours, per our records; the rest can take longer.
- Region — Silverback Gaming's stated coverage runs to the United Kingdom, Bulgaria and wider Europe, so availability outside those regions is not guaranteed.
A player comparing options within this selection can also check payment coverage: Skrill, alongside Neteller, Mastercard, Visa and Interac Online, is accepted at all four casinos carrying Silverback Gaming in this selection, per our records — a useful filter if a preferred payment method matters more than the game list itself. For a broader look at operators built around fast mobile play or a longer verified track record, the mobile casinos hub and the trusted casinos hub cover ground this page does not.
Common Misconceptions About Silverback Gaming
- Award shortlists equal high payouts — Aztec Luck's 2021 CasinoBeats Slots Studio Debut shortlist recognised design and launch quality, not a return-to-player figure; it says nothing about how a slot pays out over time.
- Relax Gaming made these games — Silver Bullet is a distribution programme; Silverback Gaming develops its own titles and Relax Gaming carries them to operators, a distribution role rather than a development one.
- A title's name reveals its mechanic — names like Mystery Stacks suggest a feature direction, but the exact bonus mechanics of an unpublished-spec game should not be assumed from the title alone.
- New ownership changes the license — GAN Limited's 2021 acquisition and SEGA SAMMY CREATION's 2025 acquisition of GAN changed corporate ownership and distribution rights, not the UKGC license the studio already held.
Verdict on Silverback Gaming
"Silverback Gaming's catalogue is small enough that its UK Gambling Commission license and its listing across licensed operators matter more than the brand name — check those before the titles."
Silverback Gaming suits a player curious about a small, regulator-backed studio rather than one hunting a wide slot library — the practical route is to pick a licensed operator from the casino directory or the new casinos hub that lists this provider, confirm the casino's own license and payout window, and treat the studio's small output as a known limitation rather than a hidden one.
Gambling is entertainment, not a way to make money or fix finances. Set deposit and time limits, take regular breaks, and use self-exclusion tools if play stops feeling like fun. Licensed operators provide these tools — using them is a sign of control, not weakness. Learn more on Responsible Gambling →
