A murder mystery game involves players assuming roles from a script, solving puzzles within the script to achieve game objectives, thus engaging in a form of role-playing game.

The game often includes elements such as character selection, script reading, clue investigation, roundtable discussions, voting for the culprit, puzzle unveiling, and case review. Before the game commences, each player selects a different character and receives a corresponding character script. Through the singular perspective of their chosen character, each player endeavors to comprehend the entirety of the script's narrative. They immerse themselves in the story from a first-person perspective, gather information about the case, discern character relationships, and identify relevant clues.

In the game, the information obtained by each player is relatively limited and one-sided. Players perceive varying timelines, case clues, and plot details from different character viewpoints, and there might even be secrets that need to be kept hidden from one another. Consequently, in order to uncover the truth behind the case and restore the integrity of the story, players must interact, gather and analyze information, and deduce the complete narrative progression and the true culprit behind the case.
