What these games are actually about

Pragmatic Play made three of the five mystery games on this list. Cult is a horror game played on a 5x4 grid with a top payout of 10,000x. Moonshot is based on a lunar conspiracy and pays up to 5,000x. Then there is Madame Mystique Megaways. This one has a fortune-teller theme, uses the Megaways system, and offers a 96.67% RTP, which is the highest return rate on this page.

The biggest potential win comes from an Onlyplay game called Lucky Ferret. It has a detective theme on a 6x5 grid and pays up to 20,000x. Mascot Gaming offers Secrets of Papyrus, which is an Egyptian tomb game with a 2,000x max win. The mystery label is used very loosely here. It groups together everything from fortune tellers to archaeology, and the games do not share any specific mechanics.
