What's inside the Secrets of line

By regulatory class

  • Class II2

Every documented entry in this line carries the same class designation.

By cabinet platform

  • AVP2
  • Bingo2
  • CDS1
  • Ascent1

The platform is the hardware family. It is what you recognise from across a floor, before you can read a single game name.

Coverage here

  • Titles documented4
  • With official artwork0
  • Filmed by slot channels3

Artwork comes from IGT's own product pages. "Filmed" counts titles named in recent uploads across the 138 slot channels we track — it is a popularity signal, not a completeness claim.

Other IGT lines

Manufacturers run several branded families at once. These are the rest of IGT's.

Why there's no single "Secrets of" machine

Manufacturers ship a successful title as a family, not one box. Each entry above is a distinct game with its own maths, artwork and cabinet — and casinos install whichever versions they license. Asking for "Secrets of" on a casino floor can mean any of these 4.

The same applies to payback: there is no single RTP for the series, or even for one title — manufacturers ship multiple par versions per game and the operator picks one.
