We are doing our best to coordinate the preparation of the game-workshops according to the booking-situation. Payment is possible on site in cash or with electronic purse. If the number of participants changes you do not have to notify us, as long as the maximum number of participants is not exceeded. If the number of participants shrinks the price per person is increased by a small amount. It is possible to cancel your booking until 24 hours before your desired timeslot. Please be punctual (ideally 10 min before)! If you arrive late, you cannot play the whole 60 minutes! If you have any further questions, please read our FAQ´s.
