FroGames — Moments You'll Remember
Someone remembers a name. Someone else a place. Yet another person a date. And in the end, you have to decide together if you've listened enough.
WHAT IT'S ABOUT
A whispered investigation in four voices
Dominique Bodin returns with the Witness series, a cooperative game system that transforms asymmetric information into narrative tension. In The Sigma Club, the case moves to Switzerland: a university in Lugano, a murdered student, and a shadow that stretches to Italy. The graphic clues by Jochen Ewert build a visual puzzle that only unfolds if all four listen carefully.
Each player receives secret clues — cards with fragments of information, names, places, times — and whispers them to the others in four rounds of forced communication. No one ever has the complete picture. The challenge is not to solve the case alone, but to collectively reconstruct a coherent story through fragmented memories and information that accumulates round by round. In the end, three questions. And only those who truly listened know the answers.
What they're saying abroad
A game that forces you to trust others' memory, and doubt your own.

Eight cases intertwined like a serialized detective novel for the tabletop.

FrogScore · FroGames editorial rating · based on rules, international reviews, and play sessionsThe elements of the case
What passes from hand to hand
Clue cards
Visual and textual fragments distributed asynchronously. Each player only sees part of the puzzle: a name, a place, a time, an object. The truth is in the sum.
Whisper cards
Determine the direction of whispers in the four rounds. Information circulates following precise arrows: no one can decide who to talk to, the system forces sharing.
Final questions
Three questions about the case that each player answers in secret. Correct answers earn points: whoever memorized best wins, but everyone must have understood to solve the case.
Campaign booklet
Eight cases intertwined in a story that starts at the University of Lugano and reaches Italian mafia. Each solved case opens the next, building a complete narrative arc.
In an hour, you'll have a story to tell. And you'll realize that each of you remembers it slightly differently.
A game in five moments
What happens at the table
Not the rules. The experience.
The prologue read together
Someone reads the case introduction aloud: a missing professor, a student found dead, a campus in shock. Then everyone receives their secret clue cards. Silence begins. No one knows what others know.
First round of whispers
Whisper cards indicate direction. Each player whispers their clues to their neighbor: names, places, times. Information passes by word of mouth, without being able to write it down. The listener must remember everything.
Round 2, 3, 4: accumulation
Now you also whisper what you heard before. Information layers up: a name links to a place, a time to an event. The picture becomes complete, but memory falters. Someone confuses a detail. Someone else corrects it, perhaps.
The three questions
End of whispers. Everyone answers in secret: who is the culprit? Where did it happen? When? The answers are compared. Those who listened well earn points. But the real score is collective: if everyone is wrong, the case remains unsolved.
The revelation and the next case
The solution is read. Some say 'I knew it!'. Others slap their foreheads. And then someone notices a detail in the ending that opens the next case. The campaign continues, and now you know the story is bigger than a single murder.
How to play
The flow of each case
Four identical rounds, then the final judgment. Simple in theory, ruthless in practice.
Each player receives secret clue cards. No one can show them to others. Everyone reads their own fragments of information: texts, images, symbols.
The Whisper card indicates the direction. Each player whispers their clues (and those received in previous rounds) to the designated neighbor. No writing, only voice and memory.
Whispering is repeated for a total of four rounds, changing direction each time. Information circulates, accumulates, gets confused. Whoever loses a piece never recovers it.
Each player answers the three case questions in secret. The correct solutions are revealed. Individual points for each correct answer, but the group only wins if the case is solved collectively.
Why it's different from others
Six mechanics that make a difference
Mandatory oral communication
You cannot write, you cannot show. Only whispers. Memory is your only tool, and voice the only channel. Every oversight is a clue lost forever.
Rotating asymmetrical information
No one ever has the complete picture. Whisper cards change the direction of whispers every round, ensuring that information circulates but never predictably. Who receives what depends on the system, not strategy.
Layered narrative puzzle
Clues are not isolated data: they are pieces of a story. A name + a place + a time form an event. And events are linked together in a causal chain that you must mentally reconstruct.
8-episode serial campaign
Not unrelated cases, but a single story unfolding in eight acts. Each solution opens new questions. The University of Lugano is just the beginning: the plot reaches the Italian mafia, with twists that recontextualize previous cases.
Individual and collective scoring
You win personal points if you answer correctly. But the case is only solved if the group as a whole has understood the truth. A balance between light competition and necessary cooperation.
Very fast games
10-25 minutes per case. You can play an episode during lunch break, or chain three in an evening. No laborious setup, no game board. Just cards, voices, and thinking heads.
How it ends
How to win and how to lose
The scoring is double: individual (who has the best memory) and collective (if the case is solved).
Individual and collective victory
- Each correct answer to the three final questions earns personal points
- The group solves the case if they collectively identify the culprit, location, and motive
- Points accumulate over the 8 cases: whoever has the highest total wins the campaign
Defeat (and frustration)
- If the majority answers the key questions incorrectly, the case remains unsolved
- Those who forget crucial clues in whispers cause everyone to lose information
- No elimination: everyone plays until the end, but the weight of lost memory is felt
Witness is not a game about deduction, it is a game about trust in shared memory. And you will discover that this is the most fragile resource at the table.
Frequently asked questions
FAQ about Witness: The Sigma Club
Can it be played with fewer than 4 players?
No. The game is designed for exactly 4 fixed players. The whispering structure and clue distribution do not work with different numbers. If there are 3 or 5 of you, this is not the right game for that evening.
Can I take notes during whispers?
The rules explicitly forbid it. You can (and must) only write when answering the three final questions. During the whispering rounds, memory is the only tool. This very limitation creates the game's tension.
Do the 8 cases have to be played in order?
Yes, absolutely. The Sigma Club is a narrative campaign: cases intertwine, characters return, and revelations from one episode shed light on previous ones. Playing out of sequence ruins the story and makes clues meaningless.
How long does the entire campaign last?
Eight cases of 10-25 minutes each: 2-3 hours total if you play it all at once, or 3-4 evenings if you prefer one episode at a time. The serial structure lends itself well to both modes.
Is it available in Italian?
This edition is in English. The game is highly language-dependent: clue cards, narrative texts, and final questions require a good understanding of the language to work.
Witness: The Sigma Club is a cooperative investigative game for exactly 4 players, with games lasting 10-25 minutes per case and a recommended age of 10+ years. Designed by Dominique Bodin and published by Deep Print Games, the game uses mechanics of limited oral communication and shared memory: each player receives secret clues and whispers them to others in four mandatory rounds, with no possibility of writing. The eight cases form a serial narrative campaign set between Switzerland and Italy, with a university under investigation and the mafia in the background. Available on FroGames.it.
