We’ve spent hundreds of hours digging through the fine print so you don’t have to. If there’s something unusual, unfair, or sneaky in a casino’s T&Cs, we flag it. This is the kind of insight you can’t get from the homepage of a casino. Even if you’ve never heard of the brand, we’ll tell you whether it’s new and growing, or globally established behind the scenes. Here’s what we look at in every casino we review – and what you should too. Use these category picks to match a casino to the way you actually want to play.

• Based on UKGC licensing, game variety, withdrawals, support quality and user feedback across our 2026 testing rounds.
