This is an educational guide to how UK online gambling works. Figures are typical industry values and vary by operator. Play for entertainment, never as a way to make money, and only ever stake what you can afford to lose.
What Is eCOGRA?
eCOGRA is an independent testing agency that checks online casino games for fairness. If you've seen its seal on a casino, it means the games have been audited by a third party — here's what that involves.
What it tests
eCOGRA examines whether a casino's random number generators are genuinely random and whether the published return-to-player (RTP) percentages are accurate. It can also review whether an operator handles players fairly.
What the seal means
An eCOGRA seal signals that an independent body — not the casino itself — has verified the games' fairness and payout accuracy. It's a mark of added transparency.
Testing vs licensing
It's important to understand these are different things. A licence (like the UKGC's) is regulatory permission to operate; eCOGRA is independent testing that complements it. The strongest sites have both. See what a UKGC licence means and how RNGs work.
