Mysterium without a scorekeeper: you pick Won or Lost, Teamzy counts the wins
In Mysterium, the ghost and the psychics win or lose together. At the end, you pick Won or Lost, and Teamzy keeps the match in the history. Over your game nights, you see how many matches your table has really won.
The rules of Mysterium in 30 seconds
Mysterium is a cooperative game by Libellud, for 2 to 7 players. One player is the ghost: they know who the murderer is, but they cannot speak and can only send Vision cards. Everyone else is a psychic: each must find their own character, location and object, helping one another. There are no points to note and nobody wins alone. The psychics have 7 hours, one round per hour, to finish their investigations. If one investigation is not finished by the end of the 7th hour, the whole table loses. Otherwise, the ghost sends a last vision and the psychics vote to name the culprit: the right one, the whole table wins; the wrong one, the whole table loses.
How a game of Mysterium ends
There is nothing to count: the game has two parts, and the table wins or loses as one. First, each psychic must find their character, then their location, then their object before the end of the 7th hour: a single unfinished investigation and the game is lost. Then comes the final vote: the psychics name the culprit among the table's investigations, and the game is won if they pick the right one. The clairvoyance points only matter in that final vote, and the ghost plays with the table: they win or lose like the psychics. In Teamzy, there is nothing to enter: you pick Won or Lost.
How a game ends, and the difficulty
| What counts | Points |
|---|---|
| Each psychic found their 3 cards, then the right culprit at the final vote | won |
| An investigation not finished at the end of the 7th hour | lost |
| Wrong culprit at the final vote | lost |
| Difficulty | easy, medium or hard |
An evening for five, 4 investigations finished before the 7th hour and a win
Lucas plays the ghost; Emma, Hugo, Léa and Chloé are the psychics. They pick the medium level: with four psychics, 7 characters, 7 locations and 7 objects go on the table, and the ghost has a few crows to change their hand. In Teamzy, there is no draw and no level to set: "Whole table" gathers the five players.
- 1Every hour, Lucas sends each psychic a vision: one or more Vision cards, and not a word. The psychics talk it over while the sand timer runs, place their pawn on the card they think is meant, then Lucas lets them know with one knock on the table for yes and two for no. In the 3rd hour, he uses a crow to change his hand.
- 2Emma finishes her investigation in the 4th hour: she moves up 3 steps on the clairvoyance track, one per hour left. Léa finishes in the 5th hour, then Hugo in the 6th. Along the way, the psychics also bet on the others' picks with their clairvoyance tokens.
- 3Chloé finds her last object in the 6th hour: all four investigations are finished before the end of the 7th hour. On to the final vote.
- 4Lucas secretly picks Hugo's group as the culprit and sends three Vision cards, one for the character, one for the location and one for the object. Without talking, everyone votes: after the bets, Chloé is one of the furthest behind on the clairvoyance track and sees a single card, while Emma, the furthest ahead, sees all three. Three votes out of four name Hugo's group: it is the culprit.
The table wins: the four investigations are finished in time and the final vote names the right culprit. There are no points, just one shared win, for the four psychics and the ghost.
In Teamzy, on the end-of-game screen, "Whole table" gathers Lucas, Emma, Hugo, Léa and Chloé: tap Won, then save the match: it joins the history, won by the whole table. "Save and play again" saves it the same way and sets up the next match with the same table. Before tonight, 4 matches of Mysterium had already been played: 2 won and 2 lost. With this one, the game details show 5 matches, and each of the five players has 3 wins, a 60% rate. Chloé, Emma and Hugo appear under "The best" (on a tie, alphabetical order breaks it), Lucas and Léa in "See the full leaderboard". Teamzy remembers every match and keeps the count for you: all you have to do is play.
The questions that come up at the table
The table wins in two steps. First, each psychic finds their character, location and object thanks to the ghost's visions, before the end of the 7th hour. Then the final vote names the right culprit: the psychics vote in secret, the majority wins, and the ghost does not vote. The win is shared by every player, the ghost included. In Teamzy, you tap Won on the end-of-game screen: the match joins the history and the game details.
The Mysterium page on the Libellud websiteThe whole table loses in two cases: an investigation is not finished by the end of the 7th hour, or the final vote names the wrong culprit. In the first case, the final vote does not even happen; in the second, every investigation was finished but the last vision was misread. In Teamzy, you tap Lost: the defeat counts for the whole table, never for a single player.
Nothing but the final vote. During the investigation, a psychic who bets on another's pick with a clairvoyance token moves up the track if they were right, and finishing an investigation early moves them up by as many steps as there are hours left. At the final vote, the higher a psychic is on the track, the more cards of the last vision they get to see: one, two or three. They are not winning points: Teamzy does not note them, and the track is only used from 4 players.
The level sets how many character, location and object cards go on the table, and the ghost's crows. With four psychics, there are 6 cards of each kind on easy, 7 on medium and 8 on hard. The ghost can change their hand with a crow every round on easy; on medium and hard, they only get a small number of crows for the whole game, given in the rulebook. Teamzy recalls these three levels in the "How do you win?" help, but it does not store the level: the match only keeps Won or Lost.
Yes. With 2 or 3 players, each player who is not the ghost plays two psychics, and the clairvoyance track is not used: with 2, the player names a single group in the final vote; with 3, the two players agree on the culprit. Teamzy sets up a game of Mysterium for 2 to 7 players, 5 by default, and "Whole table" gathers everyone, ghost included.
No. Mysterium is cooperative: there is no score and no ranking, and nobody wins alone. That is why Teamzy has no score sheet for this game: at the end, you pick Won or Lost, and the app counts the wins of the people who play. The Mysterium expansions are left aside.
A little. In the 2025 Refresh edition, the crows become three candles for the whole game, the rulebook mentions neither the clairvoyance track nor the difficulty levels, and the final vote is made together: the psychics agree on one answer, or decide by majority. The ghost and the 7 hours stay the same, and the win or the loss is still shared. Teamzy only notes Won or Lost, so it suits both editions.
The Refresh edition rulebook on the Libellud websiteWith Teamzy: save every match of Mysterium with Won or Lost. The game details show the number of matches played and, under "The best", each player's wins with their rate. Since the whole table wins or loses together, the people who play every match all have the same figure, which is your table's. "See the full leaderboard" lists them all, and every match stays in the history.
