In Poissy, The Exit's Beta Prison drops you into an experimental jail where your future hinges on your ability to work together. A mission that flips the usual escape theme with an original storyline.

This time you don’t go to prison to escape, but to take a test... At Poissy, The Exit offers La Prison Bêta, an escape game that imagines an experimental prison where inmates serving short sentences have one hour to prove they can reclaim their place in society. If there’s a chance to go free, the only path is to work together.

A prison where cooperation is the verdict

In the world of The Beta Prison, players step into the roles of inmates sent to a pilot facility. The premise is straightforward: if the team proves it can cooperate and stand together, an early release might be on the table. If not, the sentence must be served in full, with no reductions.

This scenario leans on prison-movie conventions while loading them with a fresh twist. Here, the goal isn’t just to escape, but to prove the team deserves a second chance.

Sixty minutes to prove your worth

Before the game begins, the game master lays out the context and the mission’s rules. Once the door is closed, the clock starts for a one-hour stretch of puzzles, observation, and hands-on challenges.

Every participant can contribute in their own way. Some will spot a detail, others will come up with a solution or push the team forward with an idea. More than speed, it’s the ability to communicate and move forward together that lets you progress.

A mission designed for players who love solving puzzles together

The Beta Prison can be a great pick for a night out with friends, colleagues, or family, as well as for players just discovering escape games or those who already have several missions under their belt. The storyline emphasizes cooperation, making it a venture where everyone can find their place.

The theme may also appeal to fans of prison-set worlds or stories that thrust players into a shared dilemma rather than a simple series of puzzles.

A new take on the prison universe

Many rooms kick off from a cell or penitentiary setting. The Prison Beta atThe Exit offers a different angle by imagining a prison where the challenge hinges on mutual aid rather than pure escape.

This kind of scenario shows that escape rooms are still pushing the boundaries of storytelling. A single prison cell door can conceal far more than a simple escape attempt... as long as the whole team is moving in the same direction.
