Methodology
CAS1NO builds a knowledge base in which every fact can be traced back to its source. Three principles govern everything we publish:
1. A source chain per fact
Every data point carries a source reference (source, time collected and level). The catalogue is gathered from open, public sources; no paid APIs are used. A fact without a source chain is not published.
2. Confidence, not security theatre
Every fact has a confidence weighting. Higher confidence requires independent confirmation. Two facts that contradict each other are both shown (for example theoretical and observed RTP) — we never hide a source behind a "true" number.
3. Four eyes before an assessment
Claims are proposed by one actor and reviewed by an independent one — the same actor can never both propose and approve. Every approval, rejection and withdrawal is logged irreversibly (append-only) in the estate’s system of record. The publication gate closes automatically if a review is missing or a source has been withdrawn.
What we do not do
We publish no casino assessments without a completed review, no aggregate ratings without a basis, and no RTP “certifications” that we have not measured ourselves. Review status is always shown honestly.
Source references
Sources are coded (S01, S04, S06, S08, S18 and others) and shown per field on detail pages. Questions about the methodology: see the estate documentation in the repository.
How to read the cover
Every game gets a cover drawn from its own recorded data, not from an image. The same game always gets the same cover.
- The outer ring shows theoretical RTP on a 90–100 % scale. A hollow marker means the value lies outside the scale.
- The inner arc shows the highest recorded win on a logarithmic scale, ×10 to ×100,000. A full arc means ×100,000 or more.
- Six bars show the volatility class, from low (one bar) to very high (six).
- The dots show the grid: one dot per cell, columns × rows.
- The short scale under the grid shows the number of paylines or ways, logarithmic.
- The diamond: filled gold means jackpot-linked according to the source. A dashed outline means no jackpot link is recorded. We never draw a “no”, because no source states it.
- Dashed outlines mean not recorded. A game with fewer known facts therefore looks sparser, not worse.
- Games with no recorded facts are drawn almost empty and therefore look alike in their data. That is deliberate: what is missing must show as missing, not be filled in. The identity mark tells them apart but says nothing about the game.
The cover is not a quality rating and not a recommendation. Colour follows the provider and is pure ambience (a game from a scraping source with no real studio is grey). The fine pattern behind the gauge, the thin notched ring around it and the soft colour fields behind are the game’s identity mark, not data.
