Methodology

What we collect

Once a week, for each casino we cover, we load the public lobby pages from inside a country that casino serves. We record, for every game the lobby displays: the section it appeared in, the position it held in that section, the country we viewed it from, and the ISO week of the visit.

We do not log in. We do not launch games, place bets, or interact with wallets. We read the same pages any visitor sees, at roughly one request per second, once per casino per week. The full posture is on our crawler policy page, including how an operator asks us to stop.

How position becomes a score

Two weights turn a lobby ordering into a number. A game’s position within a section is weighted by 1 / log₂(p + 1), so first place scores 1.00, tenth scores 0.29 and fiftieth scores 0.18 — steep at the top, flat in the tail, because the difference between position 50 and position 60 is not meaningful.

The section itself is weighted too. A “popular” or “top” shelf scores 1.0, because operators order those using their own play data. The home lobby scores 0.8, “recommended” 0.7, “new” 0.4, and the full A–Z catalogue 0.2 — a game appearing somewhere in an alphabetical list tells us almost nothing.

Those products are summed across every casino in the region for that week, averaged across exit countries where a region uses more than one, and normalised so the highest scoring game in that region and week is 100.

What the score is not

Lobby order is set by the operator. It reflects some mixture of their own play data, paid placement bought by game providers, CRM campaigns, and live A/B tests. We cannot separate those components from the outside, and we do not pretend to.

So the score measures prominence: how hard casinos in a region are pushing a game. It correlates with play, because operators generally do promote what people play. It is not a measurement of play, it is not a prediction, and it says nothing whatsoever about your chances on any given spin.

This is why nothing on this site says “most played” or “most popular”. If you catch us using those words, we have made a mistake — please tell us.

Guardrails

• A game is ranked only if at least two casinos in that region carry it. One casino promoting something heavily is not a trend.
• Failed or partial crawls are excluded from scoring entirely rather than quietly diluting the week.
• If the number of casinos we successfully crawled in a region falls below 60% of the previous week, the week is flagged and pages show “partial data” instead of a week-over-week movement.
• Our editorial rating of a casino never enters the prominence score. It is used only to break ties when two casinos offer the same game at the same lobby position.
• Every published number carries the week it was observed and how many casinos it was drawn from. A score with no denominator is not evidence.

Where the game facts come from

RTP, volatility and maximum win are taken from the game provider’s own published material wherever we can reach it, and we record which source each field came from and when. Where we cannot verify a figure against a primary source, the page shows “—” rather than a number we are not confident in.

Casinos sometimes run a lower RTP variant than the provider’s default. Where we can observe which variant a casino is running, we say so on the game page.

Data sources

Where each part of this site comes from, and what we do and do not trust it for. The provenance of every field is recorded per game, so a figure can always be traced back to whoever published it.

Corrections

If a number here is wrong, we want to fix it and say that we fixed it. Send us the detail and we will correct the page and note the change.
