Unravel with your team a mystery from 1905. That was when four women were gruesomely murdered by the same serial killer in just one month. The game immerses the participants in the events of that year and also introduces them to the 6 suspects. Using clues and through elimination, they must try to pinpoint the real culprit, preferably in a more efficient and faster way than the other teams.

In this game, past and present are perfectly blended. To solve this more than 100-year-old mystery, 2 participants in each team will receive instructions via their smartphone: the guide will see the location of the checkpoints on a live map, and the team captain will see the assignments, and can enter answers and request hints. The team is further supplemented by 2 or 3 detectives who have to take careful notes and take care of the secret envelope sent in advance via post or delivered digitally. Only through efficient and coordinated cooperation is victory within reach.

Slaughter is a stand-alone concept (without a game leader, all information is delivered in advance via e-mail).
