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_at, when it was first read, and verified_at, when 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
No operator wagering rules are on record (0 currently published). This is the largest gap on the site and it is worth being direct about.
Sweepstakes operators geo-restrict and bot-block their terms pages, so those documents could not be retrieved and read at the time this site was built. Rather than fill the section with rules copied from elsewhere, it has been left empty, and the playthrough section says so plainly.
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.
