Built by a Game Mathematician
I’m Light, a game mathematician based in London, UK, specialising in slot mathematics, game design and simulation.
Over the past five years, I’ve worked across more than 100 slot and casino game models, covering both Western and Asian markets.
My work combines mathematical modelling, player psychology, programming and product design — with a focus on turning theoretical probabilities into compelling gameplay experiences.
I work primarily with Java and Python and support studios throughout the full math development process, from early concept to production-ready implementation.
Away from the desk, I genuinely enjoy gambling and a night at the casino — it keeps me close to how the maths actually feels from the player’s side of the reels.
