I studied maths at university and started my career as an odds compiler at a UK bookmaker. That's where I learned how gambling companies structure their offers — not out of generosity, but to maximise player engagement while keeping the house edge intact. Understanding those mechanics changed how I look at every casino bonus.

James brought me on to handle the numbers side of Digital Austen. When you see a "200% up to £500" bonus, the headline looks great. But the real question is: after 45x wagering at 96% RTP, how much of that bonus money can you realistically expect to keep? That's what I figure out for every casino on this site.

I also personally test every payment method. I time deposits and withdrawals, check for hidden fees, and verify that the processing times match what the casino claims. If a casino says "24-hour crypto withdrawals" but it actually takes three days, that goes in the review.

Every bonus goes through the same framework. I calculate the expected balance after clearing based on the wagering multiplier and realistic RTP, factor in game restrictions and time limits, and compare the result against other casinos on the list. The reviews include specific scenarios showing what you'd need to wager and what you could realistically expect to keep.

A 400% bonus sounds incredible until you realise it comes with 50x wagering. A 100% bonus with 25x wagering might actually leave you with more money in your account. That kind of comparison is exactly what I do in every review.
