Best 3 Oaks Gaming Casinos 2026

Last updated: June 2026

3 Oaks Gaming is the studio you might know better as Booongo. It helped popularise the hold-and-win mechanic that is now everywhere, built the hugely popular Sun of Egypt series, and rebranded to 3 Oaks to push deeper into regulated markets. It is a giant of the crypto and emerging-market casino worlds. This is our honest guide to the best 3 Oaks Gaming casinos in 2026, the games worth playing, the real RTP numbers, and where you can find 3 Oaks slots.

3 Oaks Gaming at a glance

Best 3 Oaks Gaming casinos in 2026

Here is the honest shape of it. 3 Oaks is strongest in regulated Europe, Latin America and Asia, and it is a major fixture in crypto, where Stake runs a dedicated 3 Oaks Gaming library. In the US, it is found only at sweepstakes and social casinos like Pulsz, not at the regulated real-money operators. The table below is the licensed, crypto and sweepstakes casinos we have tested where you are most likely to find 3 Oaks content. Scores are out of 10. Line-ups shift by site, so check the live lobby before you deposit.

If you play with crypto, 3 Oaks is everywhere, and Stake is the confirmed home with a deep catalogue. If you are in the UK or Europe, licensed brands carry it too. And if you are a US player, your route is the sweepstakes casinos like Pulsz rather than a real-money operator. Whichever you pick, a tested, reputable casino is the one we recommend, because the studio is only ever as safe as the operator serving its games.

Is 3 Oaks Gaming legit, safe and fair?

Yes, the studio is sound. 3 Oaks Gaming holds an Isle of Man software-supplier licence, taken in 2022, and a UK Gambling Commission licence, along with certification in Romania, Greece, Italy and other regulated markets. Its games, including the legacy Booongo titles, are independently tested for those markets.

The honest caveat is about where you play. Because 3 Oaks lives heavily at crypto and emerging-market casinos as well as licensed European ones, operator standards vary more than they would at a tightly regulated US studio. The games themselves are tested to a proper standard; the variable is the casino serving them. So a 3 Oaks slot is only as safe as the operator you choose, which makes picking a tested, reputable casino more important here than usual. See how we rate for the method behind our casino scores.

From Booongo to 3 Oaks Gaming

The name change confuses people, so here is the plain version. The studio launched in 2015 as Booongo and made its name early on as one of the studios that helped popularise the hold-and-win mechanic, with Asian and Egyptian-themed slots that did well across emerging and Asian markets. Around 2021 to 2022 it rebranded to 3 Oaks Gaming and took an Isle of Man licence, a deliberate move to break into the strict regulated markets of Europe and beyond.

There is one wrinkle worth knowing. The old Booongo business split into two: 3 Oaks Gaming, the regulated, Europe-facing arm, and a sister company called BNG that kept the Booongo name for other markets. The two share the same back-catalogue, which is why you will sometimes see the same game credited to “Booongo” on one casino and “3 Oaks” on another. They are, for a player’s purposes, the same games from the same heritage. For you, the practical upshot is that 3 Oaks is the name to look for at a licensed casino, and the games behind it have a long track record.

Hold and Win, the mechanic they helped build

3 Oaks has a real claim on the hold-and-win format. As Booongo, it was one of the early studios to popularise the mechanic that now dominates the slot world. The idea is simple and satisfying: land enough coin symbols and they lock in place, triggering a round of respins that resets every time a new coin drops. The coins carry cash values, and filling the screen or hitting the right symbols can award fixed Mini, Minor, Major or Grand jackpots, with the Grand often worth thousands of times your stake.

Most of the studio’s biggest games, from Sun of Egypt to Tiger Jungle, are built on it. Many also offer a Buy Bonus option to jump straight into the feature, and on some titles, like Book of Sun: Choice, buying the bonus actually raises the effective RTP. The honest caveat is the usual one: these are volatile games, and while a Buy Bonus can change the RTP on specific titles, it does not magically tip the odds in your favour, so treat the jackpot chase as entertainment and set your budget before you start.

The best 3 Oaks Gaming games

The Sun of Egypt series

Sun of Egypt is the studio’s signature franchise and one of its biggest successes, an Egyptian hold-and-win series whose sequels, Sun of Egypt 2 at 95.64% and Sun of Egypt 3, are among the most-played 3 Oaks games in crypto lobbies. Aztec Sun, at 95.33%, takes the same formula to the Americas. If you want to understand the studio, start with the Sun games.

The Book of Sun and classics

Book of Sun is 3 Oaks’s take on the book-style adventure slot, with Multichance and Choice variants, the latter at 95.76% rising to 97.74% with the Buy Bonus. 3 Coins, a classic-style hold-and-win game at 95.84%, is another long-time favourite. These are the games that show the studio’s range within its signature mechanic.

More to explore

Wolf Saga, at a solid 96.06%, and Tiger Jungle, a hold-and-win game at 95.86%, are two of the studio’s higher-returning titles, while Magic Apple and its sequel show the lighter, fairy-tale side of the catalogue. As with any large catalogue, the famous titles are the safe picks, so start with the Sun of Egypt and Book of Sun games and the names players actually talk about.

Highest-RTP 3 Oaks Gaming games

Most 3 Oaks slots return in the 95% to 96% band. The figures below are published defaults. Some titles raise the effective RTP through a Buy Bonus, and RTP can be operator-configurable, so the version at your casino may differ. Always confirm the number on the in-game info screen before you stake.

3 Oaks vs Playson and Wazdan

Against Playson, the two are close cousins: both are European-rooted studios built heavily on the hold-and-win mechanic, both huge in crypto, and both running a slightly lower average RTP than the market leaders. The difference is mostly heritage and theme, with 3 Oaks leaning into its Sun of Egypt and Asian-market roots. If you like hold-and-win slots, you will likely enjoy both. See our best Playson casinos guide for the comparison.

Against Wazdan, it is a question of reach. Wazdan has pushed hard into the regulated US and offers its Volatility Levels tool, while 3 Oaks is more focused on crypto, Europe, Asia and Latin America, with no regulated US real-money presence. If you want a US-regulated option, Wazdan is the pick; if you want the Sun of Egypt games in crypto, 3 Oaks is your studio. See our best Wazdan casinos guide for the other side.

Where to play 3 Oaks Gaming

3 Oaks is a crypto, European, Asian and Latin American studio. Its regulated licences cover the UK, Italy, Romania, Greece, Portugal and Brazil, among others, and it has deep roots in Asian and emerging markets through its Booongo heritage. In crypto, it is a major name, with Stake running a dedicated 3 Oaks Gaming library and its games appearing across the crypto sites in our table.

What 3 Oaks does not have is a presence in the regulated US real-money market: it is not licensed in New Jersey, Pennsylvania or Michigan. Its only US foothold is the sweepstakes and social casinos, where titles like Sun of Egypt appear at sites such as Pulsz. So for a US player, the route is a sweepstakes casino or, where legal, crypto, rather than a regulated real-money operator. As always, make sure any casino you use is legal and appropriate for where you live.

Playing 3 Oaks online: mobile and free play

3 Oaks builds for mobile. The catalogue is HTML5 and runs in a phone browser with no app, and the studio’s bright, bold art, a legacy of its Asian-market roots, reads well on a small screen. The hold-and-win games in particular, with their clear coin values and jackpot meters, are easy to follow on mobile.

Free demos are available on most 3 Oaks slots and are worth a spin before you commit, especially to learn how the Hold and Win respins behave and to feel out a game’s volatility. Use the demo to learn a game, and if you play for real, do it at a tested casino with money you are comfortable risking. Our best online slots guide is a good place to compare lobbies.

How we rate game providers

We rate the casino, not the studio, because the game’s code is the same wherever you find it. Our job on a provider page is to verify the facts, flag the things worth knowing like the Booongo rebrand and the lack of a regulated US presence, and point you at the operators that carry the games and treat you fairly.

Every company fact in the key-info box is checked against 3 Oaks Gaming material and the public record of the Booongo rebrand. Every RTP figure is a published default, with the note that some titles raise it with a Buy Bonus and that RTP can be operator-configurable. Every casino in our table has been tested by us, scored on trust, payments, game range, support and responsible-gambling tools, and carries 3 Oaks content. We do not currently earn commission from any operator. The full method is in how we rate.
