History & Company Background
While 3 Oaks Gaming itself was launched in 2021, the company was built on the back of a previous studio, Booongo who, themselves, were established in 2015. However, for the purposes of this review, we’re going to be looking at the company from 3 Oaks Gaming’s perspective, with as little mention of Booongo as possible.
Now, the reason for the rebrand isn’t totally clear, but it was somewhat influenced by the fact that the software provider wanted to position itself as a more modern studio. From the beginning, the software provider brought together expertise from all over the iGaming world, and their leadership team is very experienced.
From their relaunch, 3 Oaks positioned itself not just as a content creator but as a content enabler, too. The company’s model revolves around sourcing and distributing engaging slots from independent studios, helping them reach regulated markets efficiently through a single integration. This aggregator-focused approach allows 3 Oaks Gaming to scale really quickly, while also spending time on developing some of their own games.
3 Oaks Gaming is based primarily on the Isle of Man, but they also have offices and freelancers working across Europe and Asia! They’ve also started to expand into a large number of new regulated markets, too, allowing their games to be enjoyed by players all over the world.
In its early days, 3 Oaks Gaming (then, Booongo) was licensed in Curacao, although with the rebrand came a change in licensing, too. Today, 3 Oaks Gaming is licensed in the Isle of Man and works with a number of independent testing labs, most notably, Quinel (Quinel Limited) and eCOGRA (eCommerce Online Gaming Regulation and Assurance).

3 Oaks Gaming Product Portfolio
Online Slot Games
3 Oaks Gaming specialises in online slot machines and has built a library of over 100 titles spanning several sub-genres. Below, we’re going to explore five of their most popular video slot releases.
Boom! Boom! Gold!
A high-volatility 6×5 scatter pays slot with a gold mine theme Boom! Boom! Gold is one of 3 Oaks Gaming’s latest releases, and the game awards wins when you manage to form eight or more of any symbol anywhere on the reels. Now, each time a win is formed, a cascade feature is triggered, and this can then see Boom Multipliers dropped onto the reels, worth up to 500x!
You can also trigger a free spins bonus round by landing four or more scatter symbols anywhere in view, and during this free spins round, the multipliers do not reset between rounds! Some markets offer an optional bonus buy mechanic, too, so it’s a cool game, yes, but it is basically a clone of Pragmatic Play’s Sweet Bonanza.
777 Fruity Coins
777 Fruity Coins is a video slot from 3 Oaks Gaming that was released in July 2025, making it one of their most recent slot releases. The game’s designed to blend classic visuals with modern mechanics, and on the whole, it works very well in our opinion! Now, despite a basic 3×3 setup, 777 Fruity Coins has some excellent bonuses and features.
Firstly, you’ll find golden coin symbols on reels 1 and 3 that activate a bonus round where only Collect, Bonus, and Jackpot symbols appear. During this bonus round you gather Collect symbols to win fixed jackpot prizes (Mini, Minor, Major, and Grand), and these are worth up to 3000x!
Sky Pearls: Hold and Win
Released in March 2024, Sky Pearls marks 3 Oaks’ first-ever 4×4 grid Hold & Win title. Featuring a stunning Asian look complete with turtles, fish, frogs, and dragons, the game balances polished visuals and relaxing music with some superb bonuses and features!
The Hold & Win feature, triggered by six pearl symbols, awards three respins that reset with each new pearl, leading to four jackpots: Mini, Minor, Major, and the largest, Grand. A wild dragon symbol makes it easier to form base game wins. This is yet another scatter pays game, so wins are formed by landing 8+ of any symbol anywhere in view!.
Hawaii Riches: Bonus Bank
Another fairly recent release, Hawaii Riches: Bonus Bank, was released in January 2025. It features a 5×4 reel layout with 25 paylines set against a Hawaiian backdrop. Above the reels sits the innovative Bonus Bank board, with 20 cells each holding random multipliers from 0.6x to 300x.
Landing four or more Bonus Bank symbols collects these values; “Up” symbols can increase their values further, too! However, the game’s main attraction is its free spins feature, and this is triggered by landing 3, 4, or 5 of the scatter symbols anywhere in view. During the free spins, wilds are transformed into bonus wilds, and this brings the multipliers down from above the reels onto the game grid!
3 Jewel Crowns
3 Jewel Crowns was released in June 2025, making it another recent release. This game is designed around a very simple 3-reel, 5‑payline format with modern touches, so, while the classic structure might feel retro, the modern mechanics ensure it’s actually anything but!
The central feature, three coloured crown symbols (green, red, and blue), is what you’ll be aiming to hit once you begin playing. Each crown unlocks unique modifiers during the free spins bonus round, once triggered. Green adds seven extra spins; red places fixed Minor/Major/Grand jackpot symbols onto the reels, while blue duplicates the game board. Perhaps most exciting is the fact that all three of these crowns can be triggered together, so the modifiers can, effectively, stack on top of each other!
Jackpot Slots
3 Oaks Gaming has made jackpot mechanics a core part of its portfolio, appealing to players who actively seek out high-stakes gameplay and big-win potential. Many of its most popular titles, such as the Sun of Egypt series, feature multi-tiered fixed jackpots, Mini, Minor, Major, and Grand, each with clearly defined jackpot levels.
Now, while it’s not always the case, most of these non-progressive jackpots are won through the studio’s signature Hold and Win bonus mechanic, where landing a set number of bonus symbols triggers a respin feature that can award one of the fixed prizes. If you begin to play their slots for a bit, you’ll quickly see this demonstrated in many of their games.
Now, in addition to these fixed-jackpot titles, 3 Oaks has also introduced its innovative Must Drop Jackpot series. These are standalone 3×3 slots specifically designed to guarantee a jackpot win within a predetermined timeframe or before the jackpots reach a certain monetary figure. Unlike traditional progressive jackpots, which can take years to win, Must Drop Jackpots are programmed to pay out before hitting a set limit, so, it’s very similar to what you may remember from Red Tiger Gaming.

Game Mechanics, How They Work & Unique Features
Paylines
Traditional slots used paylines, these are the specific lines running across the reels where matching symbols must land to create a winning combination. While they’re the oldest way wins are formed in slot machines, it’s still pretty common to see them used today, and many of 3 Oaks’ slots do use paylines.
You might see 10, 20, or even 50 paylines on a single slot, for example, and in some games, you can even adjust the number of lines active on every spin! In most payline-based games, symbols need to match from left to right along an active payline to win.

- 3 Clover Pots
- Sun of Egypt
- Lion Coins
Ways to Win
Instead of fixed paylines, ways-to-win slots let you create winning combinations as long as matching symbols appear on adjacent reels, starting from the leftmost reel. A typical 5-reel slot with 3 rows, for example, will offer 243 ways to win, although it’s possible for some games to offer as many as 4,096 ways to win!

Scatter Pays
Scatter pay slots are quite unique; they don’t require you to land symbols in any position, nor do winning symbols need to touch each other. Instead, as long as you land enough of the same symbol anywhere in view, usually 6+, you win!

- Boom! Boom! Gold!
- Coin Princess
- Goddess of Egypt
Cluster Pays
These slots abandon traditional lines altogether. Instead, you win by landing clusters of matching symbols that touch each other horizontally or vertically (sometimes diagonally too). The bigger the cluster, the bigger the payout. The number of symbols required to activate a cluster varies, depending on the game, but it’s commonly five or six.

Megaways
Megaways is a dynamic slot mechanic that was developed by Big Time Gaming (BTG). Due to its popularity, Big Time Gaming started licensing out the technology, and 3 Oaks acquired one of these licenses, allowing them to use Megaways technology in their games!
In Megaways slots, the number of symbols on each reel changes with every spin. Each reel can display between 2 and 7 symbols, creating anywhere from 64 to 117,649 ways to win on a single spin. The number of ways to win is calculated by multiplying the symbols on each reel together, so you never know how many ‘ways to win’ you’ll have until the reels stop spinning!

Best 3 Oaks Gaming Slots Ranked By Demoslot Rating
Demo & Review
Our Conclusion:
Hold and win slots continue to remain popular with online players, so if you're in the market for something new in this genre and with a little less volatility, Purple Diamond might be the game for you. If, however, you want something with a bit more oomph, then you'll want to skip this one as quick as you can.
Demo & Review
Our Conclusion:
3 Oaks Gaming is no stranger to a hold and win slot, and if this style of game is something you enjoy when playing online, 4 Fairy Flowers may be a game of interest to you. On the flip side, though, these collector-type games have saturated the market since 2025, so it really is quite difficult to see what makes one stand out more than the other.
Demo & Review
Our Conclusion:
As we power on into 2026, the collection-based hold & win slots continue to be relentless in their production. Whether or not 4 Wolf Drums will appeal to you will be determined by nothing more than the theme, in my opinion, as feature- and mechanic-wise, there isn't much to separate this from hundreds of other slot games already on the market.
Demo & Review
Our Conclusion:
Such has been the long-standing popularity of Pragmatic Play's "Gates of" series that many other studios have followed suit, with various themes and designs being developed over the years.
This makes it really hard to give an opinion on each of these releases, as ultimately, they are nearly the same in every way, other than maybe an adjustment to multiplier sizes or max wins.
So, as always, when a slot genre is crowded with games, the best thing you can do is try our free demos and see which ones resonate with you the most.
Commitment to Player Safety and Fairness
Licensing & Regulation
When it comes to regulation, 3 Oaks Gaming is certified in a large number of markets, including the UK, Romania, South Africa, Greece, the Netherlands, Turkey, Italy, Peru, Georgia, Colombia, Hungary and Brazil.
They also hold a wide variety of online gambling licenses – including one from the United Kingdom Gambling Commission (UKGC), which was issued on the 9th February 2024. Their UK online gambling license number is: 063055-R-338209-005. 3 Oaks Gaming is also licensed in the Isle of Man.
They also hold a license from Romania’s Oficiul Național pentru Jocuri de Noroc (ONJN) and from Greece’s Hellenic Gaming Commission. These licenses ensure 3 Oaks Gaming’s slots can be distributed to online casinos worldwide, including in some of the most heavily regulated markets.
Partnerships and Collaborations
3 Oaks Gaming has actively partnered with leading distributors and operators to expand reach. When it comes to aggregator networks, for example, 3 Oaks has partnered with major platforms including IGT PlayDigital and Pariplay Fusion, which allows operators all over the world to access their full games catalogue with a single integration.
The studio has also secured content partnerships with major casinos. For example, its entry into Portugal came via Betclic.pt, and it supplies dozens of licensed operators in the UK, Europe, and Asia. Social casino sites (like Wow Vegas) also feature 3 Oaks’ Hold & Win games.
Interestingly, despite being a modest-sized studio, 3 Oaks Gaming also runs a developer programme that co-creates titles with smaller studios, leveraging its back-end infrastructure to bring new games to market quickly.
Fair Play & Security
When it comes to fair play and security, 3 Oaks Gaming does a pretty solid job of making sure that its games are fair and certified for markets around the world. They have teamed up with a number of leading, independent testing houses to ensure that both their games and random number generator software meet industry standards, and according to their website, they currently work with four different game certification houses.
This includes Gaming Associates, eCOGRA (eCommerce Online Gaming Regulation and Assurance), RiskCherry, and Risk Associates. The two former names are both industry leaders in the iGaming world and are approved testing houses by most regulators worldwide.
Corporate Social Responsibility
3 Oaks Gaming publicly emphasises the importance of responsible gaming. All of its products include built-in tools for safe play (like session reminders and self-exclusion options).
However, at the time of writing this review, we were unable to come across any dedicated corporate social responsibility initiatives. This is likely due to the fact that the company is still a relatively small game studio, and, typically, CSR initiatives are reserved for large operators.

Final Summary
3 Oaks Gaming has come a long way since its Booongo days, establishing itself as a solid mid-tier slot provider with a clear vision and strategic approach. While they might not be reinventing the wheel, games like Boom! Boom! Gold! are pretty obvious Sweet Bonanza clones, they’re pulling off familiar mechanics well, and their games portfolio now includes nearly 100 non-Booongo-affiliated titles.
One of the things we find quite interesting about 3 Oaks Gaming is their dual approach. They create their own content, sure, but they also act as an aggregator for smaller studios, and it’s this approach that has allowed them to enter a number of regulated markets, from the UK to Romania and Portugal. Their Hold & Win mechanics might feel repetitive if you play too many of their slots, but there’s no denying they know how to make them engaging.
However, 3 Oaks Gaming still feels like a work in progress. Their game library, while growing, lacks the “wow” factor many players associate with those from bigger studios, like Nolimit City or Hacksaw Gaming, and their heavy reliance on jackpot mechanics and Hold & Win features means their portfolio can feel somewhat samey after a while.
Still, they’re a pretty solid provider, and in just four years, they’ve managed to pivot away from their crypto-casino-focused days and reinvent themselves as a legitimate, well-regulated operator, and we look forward to seeing what they’re capable of producing in the future!
