Jon Yound

He owns the Bonus value pillar. Jon built — and rebuilds every quarter — the model that converts a marketing headline like "£200 + 100 spins, 35x wagering" into a single modelled expected-value figure. Every bonus number on sitelikeuk is his model's output, not the casino's claim.

Before sitelikeuk, Jon spent three years inside a London trading desk pricing structured products and another three modelling risk for a sports-betting exchange — work that taught him to treat every advertised number as a hypothesis until the maths confirms it. That habit shapes how he reads a bonus today: the headline is a starting point, the terms are the equation, and the answer rarely matches the promise.

Outside the model, Jon writes sitelikeuk's explainers on wagering, RTP, and game weighting — the pieces that show readers the working, not just the verdict. He answers every email that includes worked maths, and he has rewritten more than forty published scores after readers caught something his model missed. The corrections counter on this page is not a vanity metric; it is the receipt.
