3 Secret Safes is S Gaming's twenty-payline slot on a five-by-three grid. Its coloured safes lead to three different features: Vault Wilds place large wild doors over the reels, Walking Wilds move safe symbols across successive spins, and Stick N' Win keeps prize safes in position during respins. A booster can enhance the feature on entry. These are separate bonus routes, so describing every safe as an ordinary scatter would miss how this game works. The provider lists multiple RTP configurations rather than one universal return.

To compare related slots formats, read the rules of Dead or Alive 2 and Mega Joker.

The library also explains the difference between lines, ways and clusters to help put these mechanics in context.
