Booongo

Booongo made its name with Hold and Win slots: special symbols lock in place, you get a few respins to land more of them, and filling the screen can win a fixed jackpot. Its games are popular with players who like simple rules and the excitement of a respin feature.

Booongo started releasing games in the mid-2010s and has grown into a widely distributed slot studio. It supplies casinos directly and through aggregators, and has expanded into Latin America and other emerging markets through partnerships with local operators.

• 15 Dragon Pearls – a Hold and Win classic with fixed jackpots.
• Sun of Egypt – an Egyptian Hold and Win series.
• Book of Sun – a low-volatility book slot.
• Gods Temple Deluxe – scatter-driven free spins.
• 777 Gems Respin – a classic-style respin game.

In a typical Hold and Win round, landing six or more special symbols starts the feature. Those symbols stay on the reels, and you get three respins. Each new special symbol sticks and resets the respins to three. When the respins run out, you win the values on the symbols – and filling every position often pays the top fixed jackpot.
