Buy the original Mysterium if you want the full game. It plays 2 to 7 and has the most depth of any version. Buy Mysterium Park if you want something shorter and lighter for 2 to 6. Buy Mysterium Kids for children as young as 6. The 2025 edition of Mysterium is the same game with more cards and a few rule tweaks, for 3 to 7.

Mysterium vs Mysterium Park
“What’s the difference between Mysterium and Mysterium Park?” Park is a smaller, faster standalone version. It isn’t an expansion, and you don’t need the original to play it.
The big change is that Park drops the objects. Psychics work as a team to clear innocent suspects, then rule out locations, all within six turns. In the last round, they name the culprit and the place. The original asks each psychic to find a suspect, a location and an object over seven turns, then vote.
The setting changes too. Park moves the mystery from a manor to a 1950s American fairground, with the park’s former director as the ghost.
Pick the original if: you want the full experience, play with five to seven, or love the clairvoyancy betting and the tense final vote.
Pick Park if: you want a game under half an hour, play with two to four, or have a group that found the original’s setup too fiddly.
BoardGameGeek members rate the original a little higher, 7.2 to Park’s 7.0, and rate Park as lighter, 1.4 to 1.9 on their complexity scale.

The 2025 Edition Is the Same Game With More Cards
The 2025 edition is the original Mysterium, reworked. If you already own the original, you don’t need it.
According to Libellud’s 2025 rules and BoardGameGeek’s notes on the new edition, the changes are:
- 24 suspects, 24 locations and 24 objects instead of 18 of each, in three color-coded sets.
- Object cards are now the same size as the others.
- Three candle markers replace the crows for redrawing the ghost’s hand.
- A pocket watch replaces the clock board.
- The ghost may take back earlier vision cards that are misleading a psychic.
- 3 to 7 players, with a 3-player variant where each psychic plays two colors. There are no 2-player rules.
Libellud’s own site now lists only the 2025 edition, though the original is still widely sold. If you play as a pair, get the original or Mysterium Park; the 2025 edition starts at three.

Mysterium Kids Is a Different Game
Mysterium Kids: Captain Echo’s Treasure is a separate game for ages 6 and up, made by different designers, Antonin Boccara and Yves Hirschfeld.
There are no picture visions. The ghost player shakes and taps a tambourine to hint at one of five cards in the manor’s rooms, and everyone else has to agree which one the sound pointed to. A different player is the ghost each round.
BoardGameGeek lists it as the 2023 Kinderspiel des Jahres winner, Germany’s children’s game of the year. It’s the right pick for families whose kids are too young for the original.
