Our Methodology

Every ranking on this site follows one transparent process. We judge casinos on how well they serve a Megaways player, not on the size of a welcome banner. Here it is in full.

1. Licensing first

A casino is only eligible for our tables if it holds a current UK Gambling Commission licence, verifiable on the public register. No licence, no listing. This guarantees tested slots, fund protection and real recourse for players.

2. Megaways library size and quality

We count how many Megaways titles a casino carries and judge the quality — whether the big names are present and whether the major studios (BTG, Pragmatic, Blueprint, Red Tiger and the rest) are represented. Range backed by quality beats a padded count.

3. RTP versions

Because many Megaways slots ship in multiple RTP versions, we check which the casino runs. Casinos running the higher-RTP versions of the headline titles rank above those quietly serving cut-down ones.

4. Fairness and payouts

Every slot must be independently tested as a condition of the UK licence. We also withdraw from each casino and time it, because a big Megaways win is only as good as the payout behind it.

5. Hands-on review

We play the headline Megaways titles on desktop and mobile, so our ratings reflect real experience — how the slots run, which versions are used — rather than the marketing.

6. Independence

We earn commission on sign-ups, but it never moves a casino up the table. Rankings follow our review and the criteria above alone. We publish corrections openly — if you spot an error, tell us.
