Zillion Games is one of iGaming's most compelling growth stories. Starting from a lean portfolio, the studio has scaled to 600+ casino integrations across 50+ countries while posting 215% revenue growth year-on-year. Two EGR wins in 2024–2025 confirm what the numbers suggest: this isn't just fast growth, it's quality growth. With a diverse slot catalogue, sweepstakes solutions, and a custom game development service, Zillion offers casino operators a genuine one-stop content shop. The Curaçao licence and iTechLabs RNG certificate provide a solid compliance baseline, though operators requiring Tier 1 licences (UKGC, MGA) should verify coverage. For operators looking to add a proven, rapidly expanding studio, Zillion is a strong addition.

Key Growth Metrics
Game Portfolio
Zillion's catalogue spans 70+ high-performing video slots across popular themes, with a deliberate focus on unique mechanics and immersive gameplay. Rather than chasing volume, the studio prioritises slot concepts that generate strong GGR for operators. Seven of their innovative titles rank among the top performers by gross gaming revenue.
Beyond slots, Zillion offers sweepstakes solutions designed to boost user acquisition and elevate player excitement, which is increasingly sought by operators targeting North American and social casino markets. The studio also provides a dedicated custom game development service, enabling casinos to commission exclusive, branded titles tailored to their player base.
