Dr. Divesh Garg is a game mathematician with a PhD in mathematics who has built slot maths models since 2021. He fact-checks the game maths on Online Pokies.

Dr. Divesh Garg is a game mathematician who designs and validates the maths behind slot games. He fact-checks the game pages on Online Pokies, making sure every RTP, volatility, hit frequency and jackpot figure we publish is correct and accurately explained.

Divesh holds a PhD in mathematics from J.C. Bose University of Science and Technology, YMCA, and a Master of Science in mathematics from Jamia Millia Islamia. He spent seven years in academia, as an assistant professor at GGDSD College and then at Galgotias University, where he taught mathematics and published research in probability and statistics.

In 2021 he joined Aristocrat Gaming as a Senior Game Mathematician. Over four years he led the mathematical modelling of slot games from concept to production sign-off. That work included building paytables and running Monte Carlo simulations to verify RTP, volatility and bonus-feature payouts on released titles. Since July 2025 he has been a game mathematician at Ingenuity Gaming, building and validating maths models for slot and casino games.

At Online Pokies, Divesh checks the numbers and the explanations behind them: what an RTP figure means over a real session, how volatility shapes wins and losses, and how bonus features and jackpots are funded. He reviews the maths only. The casinos we list, and their order, are decided by our editors.
