Overview
Booongo (BNG for short) is a slot-focused provider founded in 2015. It started out in Austria, then moved its base to Willemstad, Curaçao in the Caribbean, and by 2017 it held a Curaçao eGaming license and QUINEL random number generator certification. It makes video slots only, with no table games or live games.
What made Booongo’s name was its “Hold and Win” slots. You collect specific symbols, lock them in place and respin, going after 4 jackpot tiers: Mini, Minor, Major and Grand. They are especially popular in Latin America, Asia, Eastern Europe and the CIS region.
Booongo and 3 Oaks Gaming
In 2021, Booongo split its business in two. The division serving strictly regulated markets moved to a new brand, 3 Oaks Gaming, while the BNG brand continues to operate in less regulated regions.

| License | Curaçao eGaming | UK UKGC, Isle of Man GSC, Malta MGA, Romania ONJN, Portugal SRIJ, Bulgaria and others |

3 Oaks Gaming also earned certification in the Brazil, Spain and Georgia markets, and was nominated for “Slot Supplier Rising Star” at the EGR B2B Awards in 2023 and 2024.
Hold & Win mechanic
The bonus starts when a set number of bonus symbols (usually coins or suns) appear. The symbols that land stay locked in place and you get respins, and the respin count resets each time a new symbol lands. If the screen fills up with symbols or you collect specific jackpot symbols, you win the Mini, Minor, Major or Grand jackpot. It is in the same family as Pragmatic Play’s Hold & Spin.
It also often uses “Book of” style free spins with expanding symbols, as well as collect features that gather cash values. On the 3 Oaks side, it has also released games licensed from Big Time Gaming’s Megaways. Volatility is generally medium to high, and RTP is around 95-97%.

Operator Tools
Booongo builds tournaments, leaderboards, prize drops, free spin campaigns and network promotion features into its games by default. There is also a “spectator mode” for watching other players play. Operators can run these events without any extra development, which makes it popular with small and mid-sized operators that lack marketing tools.
Market
Booongo games are especially popular in Eastern Europe, Asia, Latin America and the CIS region. Because every game is built on HTML5, they run well even on low-end Android phones, which is a strength in these markets. In regulated European markets, the same games are supplied under the 3 Oaks Gaming name.
