RTP and house edge: reading the numbers properly
RTP is a long-run average, not a session forecast. This guide shows how to read a game's published figure, how volatility changes the experience, and where the number is disclosed.
RTP and house edge: reading the numbers properly. Every UK-facing casino must hold an operating licence from the UK Gambling Commission, and that licence entry is public. This guide walks through what the rules require, what an operator can and cannot do, and the specific things worth checking before you hand over money or identity documents.
Start with the licence. A remote casino operating licence number looks like 039326-R-319358-061: an account number, the licence type, and the licence identifier. Search the licensee name on the Commission's public register and confirm the status reads as active. If a site cannot produce a licence number, it is not regulated in Great Britain and none of the protections described here apply to you.
Finally, set your limits before you play, not after. Deposit limits, loss limits, reality checks and time-outs are required tools at every licensed operator, and GAMSTOP covers self-exclusion across all of them at once.
Frequently asked questions
Where can I verify a licence number?
On the UK Gambling Commission's public register. Search the licensee company name, then match the licence number printed in the casino's footer against the register entry.
Does this guide constitute advice?
No. It is consumer information about how UK-licensed gambling works. Gambling involves risk and you should never stake money you cannot afford to lose.
