The grading scale
| Grade | Score | Meaning |
|---|---|---|
| A | 85–100 | Excellent: little or no wagering, a high cap and fair time. |
| B | 70–84 | Good: standard UK terms with nothing unusual. |
| C | 55–69 | Fair: worth taking only if you'd play there anyway. |
| D | 40–54 | Weak: the terms take most of the value. |
| E | under 40 | Poor: not worth handing over your details for. |
| F | — | Do not sign up: unlicensed, aimed at self-excluded players, or outside UK rules. |
Why the terms are weighted this way
The licence and GamStop questions are pass or fail. Without a UK licence nothing else matters: the bonus terms are only as good as the company's willingness to honour them, and an unlicensed site answers to nobody in Great Britain.
Wagering carries the most points because it has the biggest effect on what you keep. The max cash-out comes next, because it decides whether a lucky run is worth anything. Time limits and the max bet rule matter less for value but cause the most complaints, so they still count.
