Fortune tellers and cults

Three of five mystery slots come from Pragmatic Play. Cult leans into occult horror at 10,000x on a 5x4 grid. Moonshot takes a lunar conspiracy angle at 5,000x. Madame Mystique Megaways goes full fortune-teller with the Megaways engine and a 96.67% RTP - the highest on this page.

Lucky Ferret from Onlyplay leads at 20,000x on a 6x5 format with a detective-mystery vibe. Secrets of Papyrus from Mascot Gaming blends mystery with Egyptian tomb exploration at 2,000x. The theme label here is loose - "mystery" covers everything from supernatural séances to archaeological puzzles, with no mechanical thread connecting them.
