About

I'm Lewis. I do the maths so you can see it.

Between 2017 and 2020 I made about £50,000 from UK bookmaker offers, tax-free, before software costs. It started with matched betting on sign-up offers. Later, a good chunk came from riskier value and each-way betting. After that I taught matched betting to beginners.

The short version

I averaged four figures a month. I don't have a tidy profit-and-loss sheet, and exchange statements wouldn't tell the story anyway, because the profit is spread across dozens of bookmaker and exchange accounts. So instead of screenshots of totals, this site proves it the hard way: worked examples on real offers, calculators that show their formulas, and walkthroughs of exactly how each play works.

What I believe

Matched betting is pure mathematics using sign-up bonuses. People hear the word "betting" and their eyes glaze over. Fair enough. But the first stage of this has a known outcome before a ball is kicked.

The later stuff, each-way no-lay, Lucky 15s, casino offers, is different. It's positive expected value, and it swings. I'll always tell you which is which. And I've no time for gurus selling £1,000 courses for something you can learn free.
