What is a higher-confidence RTP source?

A higher-confidence source usually has a provider/paytable/regulator source, date, visible game title, version label, operator or market context, and no unresolved multiple-RTP-version issue.

What should I do if the source is weak?

Do not rely on the RTP number yet. Save stronger evidence or use the root RTP Calculator only as a rough educational assumption.

RTP Source Checker

Q: Is this an RTP database?

No. This page checks source quality only. It does not look up game RTPs, certify RNG, or verify the operator version.

Use this page before an RTP or house-edge calculation when the weak point is the source itself: source type, captured date, visible title, version label, operator/lobby context, market context, paytable visibility and multiple RTP versions.

Privacy note: this tool runs in your browser. Do not enter account IDs, screenshots with private data, card numbers, bank details, passwords, document numbers, home address or support transcripts.

Responsible-play boundary: if RTP checking creates urgency, chasing, repeated deposits or pressure to raise stakes, stop. Call or text 1-800-MY-RESET for confidential support.

This page owns one job

It checks source quality before you use an RTP number as an assumption.

It is not a game RTP lookup, certification service, operator-version verifier, volatility forecast, legality check, tax answer or casino recommendation.

Higher confidence means the source is better documented. It still does not prove the live operator version, volatility, session outcome or legal availability.

Without JavaScript, use this rule: do not rely yet unless you have source type, date, title, version, operator/market context, visible rules/paytable/RTP screen and no unresolved multiple RTP version issue.

Confidence bands

Label	When it usually applies	What to do next
Higher confidence	Provider/paytable/regulator source, recent date, title, version, operator/market and no multiple-version issue.	Use the number as an assumption, not proof.
Medium confidence	Most evidence is visible, but one context field or freshness check is weak.	Recheck source before relying on it.
Low confidence	Generic article/database, missing date, missing version, or weak operator context.	Treat it as a lead only.
Do not rely yet	Unknown source, no visible RTP/paytable screen, or unresolved multiple RTP versions.	Find better evidence first.

RTP source checker FAQ

Is this an RTP database?

No. It checks source quality only. It does not look up named games or certify RTP.

What if a game has multiple RTP versions?

Do not rely yet until the operator/version label is clear.

Can I calculate after a low-confidence source?

Only as a rough educational assumption. Do not use it as evidence.
