Les as du casse is a cooperative action game where players work together as spies on a daring mission to steal a valuable blue diamond from a heavily guarded vault. The theme revolves around classic heist movie elements: security cameras, boobytraps, a high-tech vault, and a dramatic escape—all under pressure from an impending police response.
The gameplay is centered around physically maneuvering a magnetic spy figure using strings controlled by each player. Players must use coordination and precision to guide the spy across the board to complete a sequence of tasks: disabling surveillance cameras in a specific order, neutralizing a boobytrap, opening the vault by manipulating a red wire, and retrieving the diamond. Each task requires different interactions using the spy’s hook or body to manipulate objects on the board.
Once the diamond is secured, the team must quickly drop it into the getaway car and release it before the police arrive. The game adds tension by making the vault’s opening the trigger for the police countdown, meaning the final steps must be completed under time pressure.
The goal of the game is to successfully complete all mission steps and escape with the diamond before time runs out. Success relies on teamwork, dexterity, and timing. If the team manages to escape in time, they win the game—otherwise, the police arrive and the mission fails.
