Sessions last one half hour, which includes 5 minutes of briefing, 20 minutes of play and 5 minutes to get results. 6 to 20 players can play at the same time. Minors must be accompanied by an adult, even if this person does not play.

There is no minimum age but as the sessions take place in a dark area, little ones may be afraid of the dark.

...entry is offered to the birthday child (one birthday per party). Participants often purchase 2 sessions, take a break in the middle, have refreshments and eat the cake you have brought for the occasion in a small private room reserved for you and your guests.
