About the Expert

Over 10 years developing software for the gambling industry: RNG systems, odds engines, risk management platforms, and player analytics tools. I've seen how casinos and bookmakers operate from the inside.

Now I use this experience to create transparent tools that put mathematics on the player's side. My goal is to demystify the industry and help players make decisions based on numbers, not emotions or marketing promises.

About the Expert

8 years on the operator side — from risk analysis at Betsson Group to live casino operations at Evolution Gaming.

Verification Process

Every formula is tested against known results from academic sources and industry standards. We regularly audit our calculations to ensure continued accuracy. Our last comprehensive audit was completed in February 2026. Additionally, we perform algorithm reviews whenever bookmaker rules or industry calculation standards change to ensure our tools remain current and accurate.
