Mysterium: Hidden Signs

Mysterium: Hidden Signs is the first expansion for Mysterium, adding 42 new vision cards, 6 new suspects, 6 new locations, and 6 new objects. No new rules — just more content to shuffle in and significantly more possible game combinations.

The ghost gains a larger pool of dreamlike illustrations to draw from, making communication both richer and more varied. Mix Hidden Signs into the base game alone, combine it with Secrets & Lies, or use all three together for a constantly shifting experience.

What's good?

• 42 new vision cards give the ghost far more to work with
• 6 new suspects, locations, and objects dramatically increase game variety
• No new mechanics — drops straight into your existing game
• Fully combinable with Mysterium: Secrets & Lies

Who is it for?

• ✔ Mysterium fans who've exhausted the base game combinations
• ✔ Groups who want more variety without learning new rules
• ✔ A natural first purchase alongside the base game
• ✖ Not a standalone game — requires Mysterium to play

⚠️ Expansion — requires Mysterium to play. Compatible with Mysterium: Secrets & Lies.
