About RTP Ledger
RTP Ledger is an independent slot data project. We publish a recorded primary RTP for 2410 online slot entities. Volatility, hit frequency and maximum win appear only when the dataset has a value. Source status is assessed separately for each field; no game studio or casino has editorial input into the data.
What RTP Ledger does
RTP Ledger is a searchable database of slot mathematics and casino facts. Key fields show a source and confidence level when that history is available. RTP Ledger labels missing source history. The site does not operate a casino or claim that a game is due to pay.
What we track
RTP Ledger tracks RTP values, RTP ranges, implied house edge, maximum win, volatility, hit frequency, provider, release year, and game mechanics. Stake Engine records can also include an RTP value for each mode. Casino pages contain documented licensing, terms, fees, and product facts. The slot data includes values matched to dated secondary-source snapshots and legacy imports whose original upstream source may not have been retained. RTP Ledger withholds unresolved conflicts and leaves missing values blank. The full process is in the data methodology and source policy.
Why multiple recorded RTP values matter
Some games have more than one recorded RTP value. RTP Ledger shows the primary recorded value and the available range. The data does not prove that the primary value is the provider default. It also does not identify the value that a casino enabled. Check the RTP in the game paytable.
How casino profiles work
Casino pages cover 20 research areas. These areas include licensing, market access, deposits, withdrawals, identity checks, account controls, and game fairness. Each conclusion needs a dated source. Unknown and conflicting facts stay unresolved. Draft records stay out of search and have no partner link until they meet the source, freshness, archive, and human-review rules.

Limits, corrections and safety
The data can be incomplete or delayed. Legacy imports can lack full source history. If a figure does not match a current provider publication, read the corrections policy and report it. Please also read responsible gambling before you play.
