Casini is a technology-driven iGaming company building online casino products for B2B partners (operators and aggregators). We cover the full development lifecycle — from artworks and mathematical models to gameplay architectures and back-office tools.

Our team designs and expands slot games, crash/instant mechanics, card and table games, supports existing codebases, and introduces new algorithms. In addition, we build and maintain back-office system used by internal teams and external partners.

Our games are live in Asian markets, and our core focus areas are scalability, reliability, and security. We value professionalism, openness to new ideas, and a mindset geared toward solutions that operate under high load for years.
