Sources
What this site is willing to publish as fact, and what it leaves out rather than guess at.
The three kinds of claim
| Kind | What it means | Accepted for |
|---|---|---|
| primary | Read directly from the operator’s or game maker’s own published document, with the URL and the date it was read recorded. | Operator rules, published RTP figures. |
| derived | Computed from the stated rules of the game. A 37-pocket wheel paying 35 to 1 returns 36/37 by arithmetic, and nobody needs to confirm it. The derivation is published so you can check it. | Table-game RTP, house-edge figures. |
| secondary | Reported by a named third party. | Context only. A secondary source is never the sole support for a numeric claim, so no game record here publishes an RTP backed only by one. |
That last rule is applied to the data itself rather than left to good intentions. Where a record’s sourcing does not meet the standard for the claim it would support, the figure is absent from the page rather than published unsupported.
What this site will not do
- Invent an RTP. If a figure cannot be established from a primary document or derived from the rules of the game, there is no record for it.
- Use another affiliate site’s table as a source. RTP tables circulate between affiliate sites and acquire authority purely by repetition. A number with no traceable origin is not evidence, however many places carry it.
- Publish a casino-wide RTP. An average across a handful of games is dominated by which games were chosen, and is not a property of the casino.
- Present a single slot RTP as definitive. Most slots ship in several configurations and the operator picks one. See RTP configurations.
- Claim first-hand testing. Nothing here is based on anyone playing at an operator and reporting back. Where a claim would need that, it is not made.
Re-verification
Every operator rule carries two dates: Observed, the date it was first read, and Verified, the date it was last re-checked against the source. Both are shown next to the rule, because “we read this once” and “we re-read this recently” are different claims and you are entitled to tell them apart.
Old observations are never overwritten. When a rule changes, the previous one is closed with an end date and kept, so a change is visible as a change.

What is missing, and why
2 operator wagering rules are on record, for 2 of 5 operators. Every other operator’s rules are still missing, and that remains the largest gap on the site.
Sweepstakes operators geo-restrict and bot-block their terms pages, and some publish no multiplier at all, so a rule is recorded only where the operator’s own document could be read and states it. Rather than fill the gaps with rules copied from elsewhere, they are left empty; the playthrough section lists only the operators whose rules are on record.
The calculators do not depend on that data. They work on any rule you read yourself: take the multiplier and contribution from an operator’s terms and enter them directly.
