Welcome to the haunted manor of Mysterium!
Scotland, in the 1920’s... The gifted astrologist and clairvoyant, Conrad MacDowell, has inherited the family manor. The instant he sets foot in the property, he begins to feel a supernatural presence. In a bid to free the stranded spirit, MacDowell summons the pre-eminent mediums of the day for an extraordinary séance. The gathered assembly has seven hours in which to contact the ghost and solve an age-old mystery…
Unable to talk, the amnesic ghost will communicate with the mediums through visions (illustrated cards). They will have to decipher the images to help the ghost remember how he was murdered (who? where? which weapon?). The more they cooperate and guess well, the easier it will be to the catch the right culprit.
This party game is one of the most anticipated games of 2015, thanks to innovative, thrilling and immersive features. It offers cooperation and investigation with an asymmetrical gameplay. While playing the ghost or a medium, you will have fun trying to guess what other players have in their minds!
So enter in this strange manor and let yourself be led by your intuition!
In Mysterium, one player takes the role of ghost while everyone else represents a medium. To solve the crime, the ghost must first recall (with the aid of the mediums) all of the suspects present on the night of the murder. A number of suspect, location and murder weapon cards are placed on the table, and the ghost randomly assigns one of each of these in secret to a medium.
Each hour (i.e., game turn), the ghost hands one or more vision cards face up to each medium, refilling their hand to seven each time they share vision cards. These vision cards present dreamlike images to the mediums, with each medium first needing to deduce which suspect corresponds to the vision cards received. Once the ghost has handed cards to the final medium, they start a two-minute sandtimer. Once a medium has placed their token on a suspect, they may also place clairvoyancy tokens on the guesses made by other mediums to show whether they agree or disagree with those guesses.
After time runs out, the ghost reveals to each medium whether the guesses were correct or not. Mediums who guessed correctly move on to guess the location of the crime (and then the murder weapon), while those who didn't keep their vision cards and receive new ones next hour corresponding to the same suspect. Once a medium has correctly guessed the suspect, location and weapon, they move their token to the epilogue board and receive one clairvoyancy point for each hour remaining on the clock. They can still use their remaining clairvoyancy tokens to score additional points.
If one or more mediums fail to identify their proper suspect, location and weapon before the end of the seventh hour, then the ghost has failed and dissipates, leaving the mystery unsolved. If, however, they have all succeeded, then the ghost has recovered enough of its memory to identify the culprit.
Mediums then group their suspect, location and weapon cards on the table and place a number by each group. The ghost then selects one group, places the matching culprit number face down on the epilogue board, picks three vision cards — one for the suspect, one for the location, and one for the weapon — then shuffles these cards. Players who have achieved few clairvoyancy points flip over one vision card at random, then secretly vote on which suspect they think is guilty; players with more points then flip over a second vision card and vote; then those with the most points see the final card and vote.
If a majority of the mediums have identified the proper suspect, with ties being broken by the vote of the most clairvoyant medium, then the killer has been identified and the ghost can now rest peacefully. If not, well, perhaps you can try again...
