No operator links. No affiliate commissions. We have no financial stake in which games you play.

Cross-Checked

Three sources for every data point. Where they disagree, we document the conflict and publish the more conservative figure.

🚩

Transparent

Our Inspection Log publishes every data disagreement we have found. No competitor does this.

What We Do

SlotMultiplier is an independent data service that collects, cross-checks and publishes RTP, volatility, max win and specification data for online slot games. We pull from multiple sources, compare them against each other, and flag every disagreement in a public Inspection Log.

Most slot information sites are operated by affiliates who earn commission when you click through to a casino. This creates an obvious incentive to publish optimistic data — higher RTPs look better in search, and conflicts with inconvenient truths are quietly ignored. We do not operate that model. SlotMultiplier carries no operator links and earns nothing from your gameplay.

Data & Methodology

iGaming Tools
Primary source
Our primary data source. Provides RTP, max win, volatility, and specification data sourced directly from certified paytables and developer documentation. Accessed via API with rate limiting.
Secondary source
Used for cross-checking RTP and max win values. Where slot.report disagrees with our primary source beyond our conflict threshold, we record the disagreement and publish the lower (more conservative) RTP. Attribution link provided as required by their terms.
SlotCatalog
Tertiary source
Used as a tertiary cross-check and for gap-filling where our primary sources have incomplete data. HTML-scraped with caching and rate limiting in compliance with their terms of service.

Our Conflict Resolution Rules

RTP Conflicts

When two sources disagree on RTP by more than 0.05 percentage points, we record the conflict in our Inspection Log and publish the lower (more conservative) figure. A lower RTP is less likely to be aspirational or incorrect.

Max Win Conflicts

When two sources disagree on max win by more than 50×, we record the conflict and publish the iGaming Tools figure as the primary source. We note the discrepancy for manual inspection.

Missing Data

Where data is genuinely unavailable, we display "—" rather than inventing or extrapolating a figure. We never publish speculative values.

Developer Authority

Where a developer's own certified paytable conflicts with aggregator data, the developer's certified figure takes precedence. See Mega Moolah in our Inspection Log for an example.
