How we review casino bonuses

Where the numbers come from

The primary source is always the operator's own page: the promotions listing for the headline offer, and the bonus terms or general terms and conditions for the conditions attached to it. Nothing is copied from another comparison site.

Where the promotions page and the terms page disagree — which happens more often than it should — the terms page wins, because that is the document that governs the account. Where a figure is not stated anywhere, we record it as not stated rather than filling it in from a competitor's listing.

Each offer is recorded as 9 fields: match percentage, maximum bonus, free spins, the wagering multiplier, what that multiplier applies to, free-spin wagering, minimum deposit, maximum bet while wagering, and the time limit.

The one field that decides most of it

A wagering requirement of 35× can mean two very different things. Applied to the bonus alone, a €100 bonus needs €3,500 of turnover. Applied to deposit plus bonus, the same 35× on a €100 deposit matched to €100 needs €7,000 — double, for an identically worded offer.

This is why we record what the multiplier applies to as its own field, and why it carries more weight in the score than the size of the bonus. In our 52-casino study, 27% of the offers that stated a basis applied wagering to deposit plus bonus, and almost none of them said so on the promotions page.

How the score is built

The score out of 10 is an editorial judgement, not a formula with a hidden weighting we can pretend is objective. It is built from four things, in this order of importance:

What you keep. The wagering requirement, what it applies to, the maximum bet allowed while wagering, and the time limit. An offer with a low cap and clean terms scores above a larger one with 50× wagering and a 7-day window.

Breadth. Whether the welcome package covers more than slots — a separate live casino, sportsbook or crypto offer is real additional value if you use those products, and worth nothing if you do not. We say which case a score assumes.

Clarity. Whether the terms are findable, complete and internally consistent. An operator whose promotions page contradicts its own terms loses points for that alone.

Accessibility. The minimum deposit and the deposit methods that qualify. An offer that excludes e-wallets is a narrower offer than one that does not.

Two offers with identical terms get identical scores. Where you see a small gap between two operators on this site, it usually reflects breadth or clarity rather than a difference in the bonus arithmetic — and the head-to-head pages spell out exactly which.

Re-checking

Bonus terms change without announcement. Every listing carries the date it was last verified, and that date is not auto-generated — it moves when someone actually re-reads the source, not when the site is rebuilt.

If you find a figure here that no longer matches the operator's page, tell us and we will correct it. The Editorial policy sets out how corrections are handled.
