3 Oaks Gaming
3 Oaks Gaming is the studio behind the Sun of Egypt slots and the Hold and Win coin-collect feature that runs through most of its catalogue. It is a games supplier, not a casino: it builds the slots and licenses them to operators, and it has spent the last few years turning itself into a distributor that also carries other studios’ content into regulated markets. If you have played a Booongo game, you have already met the same team.

The casinos listed on this page are licensed operators that have added 3 Oaks titles to their lobbies. Your account, deposits and support sit with the operator, not with 3 Oaks, so use the list to find a site that holds a licence for your country and stocks the games, then open the provider filter in the lobby to find them.
From Booongo to 3 Oaks Gaming
3 Oaks grew out of Booongo, a slot studio that had been releasing games since around 2015. In 2021 the group reorganised. The original studio kept going as BNG, the name many players still see under a Curacao licence, while 3 Oaks Gaming was spun out to chase approvals in the strictest markets and moved its base to Douglas on the Isle of Man. The rebrand was settled by 2022. Both arms draw on the same library, which is why franchises such as Sun of Egypt and Dragon Pearls turn up under both the Booongo and 3 Oaks names depending on the market and the operator. That shared history matters when you check a game’s paperwork, because the legally responsible supplier can differ from the brand on the splash screen.
Hold and Win: the feature that made its name
Ask what makes 3 Oaks recognisable and the answer is a mechanic rather than a theme. Hold and Win is a respin bonus built around collecting money symbols. Land enough special coins and the base symbols clear, the coins you triggered with lock in place, and you get a short run of respins; every fresh coin resets the respin counter and can carry a cash value or one of the internal jackpots. Sun of Egypt is the flagship for it, now several sequels deep, with Sun of Egypt 5 layering an Ultra Hold and Win version on top of the original. The feature has been copied widely, and it puts 3 Oaks in the same lane as Wazdan and its Hold the Jackpot line and the Hold and Spin games from Pragmatic Play, both of which fight over the same coin-collect audience.
What the catalogue actually contains
The output is slot-led and leans hard on two theme families: ancient Egypt, which the Sun of Egypt run has mined for years, and Asian mythology, where Dragon Pearls and its relatives sit. Around that you get the usual animal, fruit and treasure-hunt titles, and a handful of Megaways games produced under licence from Big Time Gaming. Counting the Booongo back catalogue, there are well over a hundred titles in circulation. What you will not find is a table or live-dealer range: 3 Oaks does not make roulette, blackjack or live studio games, so if a casino offers those alongside the slots they come from other suppliers.
A studio that is also a distributor
The bigger shift since the rebrand is that 3 Oaks stopped being only a maker of games. It now runs as a distributor too, signing up independent studios and pushing their slots out alongside its own. That aggregation model is why its reach grew so fast through 2025 and into 2026. Its games and partner content go to operators through the large aggregators rather than direct integrations in most cases: Pariplay’s Fusion platform and IGT PlayDigital have carried the catalogue for a while, Games Global added it in March 2025, and in December 2025 both Relax Gaming, as a Powered By Relax partner, and Microgame in Italy signed it up, the Microgame deal alone opening the door to hundreds of Italian operators. For a supplier of its size, being on that many shelves at once is the real story of the past year.
Where 3 Oaks is licensed
The move to the Isle of Man was about credibility with regulators. 3 Oaks holds a supplier licence from the Isle of Man Gambling Supervision Commission, which is its home regulator, and from the UK Gambling Commission for supply into Great Britain. In 2025 it added a Malta Gaming Authority licence, and its games are certified for a long list of regulated markets including Italy, Romania, Sweden, Bulgaria, Greece, Portugal, Spain, the Netherlands, Brazil, Colombia and Peru, with independent RNG testing handled by Gaming Associates Europe. A supplier licence is not the same as an operator licence: it means the games are tested and approved, but the casino you sign up with still runs its own age checks, identity and anti-money-laundering controls and responsible-gambling tools. Confirm the site holds a licence for your country before you deposit.
How we weigh a supplier like 3 Oaks
When we assess a games provider we look at the things a marketing budget cannot fake: the standard of its licences, how much of the catalogue it actually builds itself, how openly it publishes RTP, and whether it has staying power. 3 Oaks scores well on regulation now, with the Isle of Man, UKGC and MGA behind it, and its Hold and Win slots have a genuine identity rather than being generic reels. The honest caveats are worth reading. It is slots-only, so there is no depth beyond the reels. RTP on its games is often configurable by the operator, so the figure at one casino can be lower than at another, which makes checking the in-game information panel more than a formality. Because it now distributes third-party studios as well as its own work, the quality across the badge is less uniform than it used to be. And the Booongo, BNG and 3 Oaks naming can make it hard to tell which entity is actually behind a given game, which matters if you ever need to raise a dispute.
Is 3 Oaks Gaming the same company as Booongo?
They share the same roots. The studio released games as Booongo from around 2015. In 2021 the business was reorganised: the original studio carried on as BNG under a Curacao licence, and 3 Oaks Gaming was spun out as the arm built for tightly regulated markets, moving its base to the Isle of Man. Both draw on the same game library, so franchises such as Sun of Egypt appear under both names depending on the market.
What is 3 Oaks Gaming's Hold and Win feature?
It is the studio's signature bonus, a respin round built around collecting money symbols. When enough special coins land, the standard symbols clear and the coins lock in place, and you get a short run of respins that resets each time a new coin appears. The coins can carry cash values or trigger one of the game's internal jackpots. Sun of Egypt is the best-known title to use it, with Sun of Egypt 5 adding an Ultra Hold and Win version.
Is 3 Oaks Gaming licensed in the UK?
Yes. 3 Oaks holds a UK Gambling Commission supplier licence, alongside licences from the Isle of Man Gambling Supervision Commission, which is its home regulator, and the Malta Gaming Authority, added in 2025. A supplier licence means the games are tested and approved; whether you can play still depends on the casino itself holding a licence for your country.
Does 3 Oaks Gaming make anything besides slots?
Its own output is slots-only, with no table games or live dealer range, so any of those in the same casino come from other suppliers. Since the rebrand, though, 3 Oaks also works as a distributor, signing independent studios and carrying their slots to operators alongside its own.
What are 3 Oaks Gaming's most popular slots?
The Sun of Egypt series is the flagship and is now several sequels deep. Other well-known titles include the Dragon Pearls line and its other Asian-themed and treasure-hunt slots, most of which are built around the Hold and Win coin-collect feature. A few games use the Megaways engine under licence from Big Time Gaming.
