Tabletop Game - Ghost Letters

The detective game "Ghost Letters" - a game with secret roles about investigating a crime.
The detective players deduce 3 true clues from 12 clues (images of objects) found at the crime scene.
The detective players are assisted by the player playing... the Ghost (the victim of the crime) who hints at the true clues through other clue hints, associatively. Among the detectives hides the Killer, who aims to confuse the investigation.

The game lasts for 4 rounds. Players choose from their hand and pass 1 clue face down to the Ghost, who reveals the successful ones. The unsuitable ones remain face down.
The player with the secret role of the Killer seeks to mislead the investigation - both in the discussion of the revealed clues and by bluffing about the clues left face down.
After 4 rounds, players vote in majority for 3 clues and the player who is the Killer.
The more players there are, the more interesting roles: Killer's associates, Witness, Expert, Blackmailer. In the extended mode, character cards with unique abilities are added to the game.
