3 Oaks Gaming Casinos — Games, Fairness and Where to Play
3 Oaks Gaming is a slot studio built on the former Booongo brand, known for Hold & Win bonus rounds and Megaways-style mechanics across a portfolio of more than 80 titles. The studio operates under Isle of Man and UK licensing and supplies its games to online casinos through several established platform partners.
Who Is 3 Oaks Gaming
3 Oaks Gaming was founded in 2021 on the Isle of Man as the rebrand of Booongo, a studio originally established in 2015. The company is owned by Green Rock Limited and operates under Managing Director Sebastian Damian.
The studio holds licences from the Isle of Man Gambling Supervision Commission and the UK Gambling Commission, with additional certification in more than ten jurisdictions, including Romania (ONJN), Portugal (SRIJ), Bulgaria, Georgia and Italy. Games reach casinos through platform partners such as EveryMatrix, BetConstruct, Hub88, SOFTSWISS and EGT Digital, and the catalogue grows by roughly 20 new releases a year. The studio has been shortlisted for the EGR B2B Slot Supplier Rising Star award in 2023 and 2024, and appeared on the CasinoBeats (2024) and SBC (2025) shortlists.
3 Oaks Gaming Games and Signature Mechanics
3 Oaks Gaming builds video slots exclusively, with Hold & Win respin bonus rounds and Megaways-style reel mechanics as its two recurring signatures. Hold & Win titles typically lock high-value symbols in place for a respin sequence, a format the studio applies across several of its animal- and mythology-themed releases, including Wolf Saga and Tiger's Gold Hold and Win.
| Game | Type | Key Feature |
|---|---|---|
| Wolf Saga | Video slot | Wolf-themed reel set |
| Tiger's Gold Hold and Win | Video slot | Hold & Win respin bonus |
| Buddha Fortune Hold and Win | Video slot | Hold & Win respin bonus |
| Book of Wizard Double Chance | Video slot | Double Chance bonus mechanic |
| African Spirit Sticky Wilds | Video slot | Sticky wild feature |
Other titles in the catalogue — Wolf Night, Tiger Stone, Tiger Gems, Tiger Jungle Hold and Win, Thunder Of Olympus, Super Sticky Piggy and Super Rich God Hold and Win — extend the same animal and mythology themes across different volatility profiles.
3 Oaks Gaming RTP, Volatility and Fairness
3 Oaks Gaming does not publish one blanket RTP figure for its portfolio: return-to-player is set per title and can be configured differently from casino to casino. RTP is a theoretical value calculated over a large number of spins, not a short-term guarantee, so the percentage that applies at a given operator is the one shown in that title's in-game information panel before a real-money bet is placed.
Fairness is checked independently: the studio's random number generator is certified by Gaming Associates Europe Limited, and its Isle of Man Gambling Supervision Commission and UK Gambling Commission licences require ongoing compliance monitoring of the games it distributes.
All 3 Oaks Gaming titles run on HTML5 and support more than 19 languages, so the same build works across desktop and the Mobile Casinos category without a separate app.
Where to Play 3 Oaks Gaming Games
Casinos carrying 3 Oaks Gaming titles are listed in the ranking above this article. Three examples from that selection are Betico, The Slotz and Beef. Which specific titles are live, which RTP configuration is loaded, and whether a demo mode is enabled can all differ between these operators, so it is worth checking each casino individually before depositing.
- Provider filter: confirm 3 Oaks Gaming (or its former Booongo listing) appears in the casino's lobby
- Licence: identify which regulator covers the casino, since this is separate from 3 Oaks Gaming's own Isle of Man/UKGC certification
- Region: some jurisdictions restrict access to specific titles or to the studio entirely
- Demo access: look for a free-play version of the slot before committing real funds
Common Misconceptions About 3 Oaks Gaming Slots
- "A slot is due for a win after a losing streak" — every spin is generated independently by the certified RNG, so past results do not influence the next one.
- "3 Oaks Gaming and Booongo are two different studios" — 3 Oaks Gaming is the 2021 rebrand of Booongo, not a separate competing developer.
- "A higher RTP always means bigger single wins" — RTP describes the theoretical return over a large number of spins, while volatility determines how wins are distributed; a high-RTP title can still pay small amounts frequently.
- "Every Hold & Win title behaves the same way" — the respin mechanic is shared across several games, but bonus triggers, symbol values and volatility differ by title.
Conclusion
"3 Oaks Gaming builds a focused catalogue of Hold & Win and Megaways-style slots for players who prefer animal and mythology themes over table or live content."
3 Oaks Gaming suits players who favour respin bonus rounds and themed reel sets over broader casino content, since the studio produces slots exclusively. Its Isle of Man and UK Gambling Commission licensing, together with RNG certification from Gaming Associates Europe Limited, provide a verifiable fairness baseline, though the exact RTP and volatility of any single title still need to be checked at the chosen casino before playing.
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 →
