What it flags

Hold vs theoretical

Tracks actual hold% by game type against the theoretical hold and spread you set for that game.

Z-score outliers, or nothing at all

Flags a game beyond 2.5σ of its theoretical for investigation, and beyond 1.5σ to watch — in either direction.

Trend and report

Builds a trend chart and an auto-generated management report ready for the monthly review.

Why directors adopt this

See internal theft first

Catch internal theft, fraud, collusion and AML exposure before they become a loss or a regulator finding.

Held to a published standard

The same verification rigor as our intelligence — sourced, documented and correctable.

Hold drifts before anyone admits a problem. A monthly Z-score against each game's theoretical is the difference between catching it in June and explaining it in December.

Questions

How does it operate?+

Built over decades of surveillance work, the reporter holds a theoretical hold and a standard deviation for every game type — both yours to set — and scores each month's actual hold against them as a Z-score. Each flag is a prompt for a closer look, not a verdict.

Does my data leave the machine?+

No. The export is read and analysed entirely in your browser. Nothing is uploaded, and closing the tab clears the data.

What can it import?+

Enter the month by hand, or import a CSV of drop, win and game type. The theoretical and spread figures ship as house defaults and should be replaced with your own property's measured hold.

Can we add our own branding?+

Yes. Add your property name and logo yourself at no cost. We also offer optional paid customisation to fit your jurisdiction and house rules.
