Booongo games
Booongo (now often branded BNG or 3 Oaks Gaming) is a slot studio founded in 2015 with a Curaçao licence. It is best known for its coin-collecting 'Hold and Win' slots such as Coin Volcano, which reach South Africans mostly through offshore casinos.

Who Booongo is
Booongo started in 2015 and grew quickly on the back of one feature: “Hold and Win”. Its slots made the coin-collect respin round a mainstream format, and dozens of studios have copied the idea since. The company reports a Curaçao licence, with RNG certification from QUINEL in 2017 and iTech Labs in 2021. Part of its catalogue has since moved under the 3 Oaks Gaming brand, and some casinos label its games BNG, so you may see all three names in a lobby.
What Booongo games are known for
- Hold and Win respins. Land six or more coin symbols and they lock while you get three respins. Each new coin resets the count.
- Fixed jackpots. Many games carry Mini, Minor, Major and Grand jackpots that pay a set multiple of your stake.
- Bonus buys. Several titles let you buy straight into the feature where the casino allows it.
- Similar layouts across games. Once you’ve played one Booongo slot, you’ll know how most of the others work. That’s handy if you like the format and dull if you don’t.
Best Booongo games
Coin Volcano is the Booongo slot most searched in South Africa (“coin volcano”, “coin volcano demo”). It mixes a volcano theme with the classic coin respins and a feature where a volcano adds extra coin value. Its RTP isn’t confirmed in our data, so check the game’s info screen. Booongo games commonly sit around 95% to 96%.
The studio’s other well-known titles include 15 Dragon Pearls, Sun of Egypt and Black Wolf, all built on the same coin-collect idea.
Where South Africans can play Booongo
Booongo and 3 Oaks games are carried mainly by offshore casinos. We haven’t confirmed a South African provincially licensed casino that lists them, so check the lobby before you deposit. 1Win is open to South Africans with a large slot section and offers 500% up to R75,000 over 4 deposits; it is licensed in Curaçao, so there’s no provincial board to complain to.
Coin-collect slots are medium to high volatility. The base game pays modestly and most of the value sits in the feature, so a short session can feel quiet. If you’re clearing a bonus, set aside enough balance to reach the feature a few times.
Jackpots on coin slots
The Grand jackpot on a Booongo slot usually needs every position filled with coins, which is rare. Treat it as a bonus on top, not a reason to play.
