Kalamba Games is a Krakow, Poland-based boutique studio founded in 2016, known for two proprietary mechanics: HyperBonus™ — a two-phase bonus buy system that offers standard and ultra bonus modes — and HyperBet™ — which lets players buy reduced RTP rates in exchange for increased volatility and higher win potential. These mechanics appeal to experienced players who want to customise their risk/reward profile beyond standard bet adjustment. Kalamba's catalogue of 50+ titles includes Book of 99 (99% RTP base game), Blazing Bull series, and Chilli Bonus Mayhem. The studio holds MGA B2B certification and distributes through Relax Gaming's Silver Bullet programme.
