Booongo built its slot library over close to a decade before rebranding as 3 Oaks Gaming, a change that came with licensing out of Douglas, Isle of Man, alongside credentials from the UK Gambling Commission, Romania's National Gambling Office and Greece's Hellenic Gaming Commission. The rebrand was more than cosmetic: it came with a modernised look and a stronger regulatory footprint, moving the studio on from an earlier reliance on Curacao-only licensing. The portfolio, now more than 60 titles, is built around Hold and Win, a respin feature in which paying symbols lock in place while the remaining reels spin again for extra prizes. It is the studio's signature mechanic, and one widely copied elsewhere in the industry since. Titles such as Super Hot Chilli lean on a classic fruit-and-fire look built around that same respin structure, while the wider catalogue also draws on Megaways licensing and the now-standard bonus buy option, alongside tournaments, jackpots and other promotional tools aimed more at operators than at players directly. For a demo player, 3 Oaks Gaming is a good place to see where the modern Hold and Win format comes from, rather than a studio chasing extreme volatility or elaborate multiplier chains. The house style favours clear symbol sets and a straightforward respin structure over layered cascading mechanics. It suits players who like the steady, symbol-locking respin format and want to compare an early, well-established take on it against the many studios that have since built their own version.
