Halfway between an outdoor escape game, a treasure hunt and a visit to Montmartre, we take you on a unique urban adventure! Divided into several teams, find clues, solve an investigation and follow a route to discover known and unknown places. As a team, set off on a quest for clues to flush out in the most famous streets of Montmartre, thwart the minutes of the infernal chrono, and manage to shed light on these strange affairs. An unusual activity, between stroll and enigma, which could well sharpen your sense of discovery… And of competition! For a business activity, a bachelor party, or a simple team challenge with friends, it's a perfect opportunity to discover Montmartre differently... And to take advantage of a reward for the best investigators! Two formulas are proposed. In a public session, you compete against other participants outside your group. Saturdays at 2:30 p.m. During a privatized treasure hunt, your group is alone on the game and no participant outside your group participates in your event.
