Which places are the oldest in Vienna? Where do you encounter mythical creatures? Why do we find mammoth bones at St. Stephen's Square? This puzzle rally promises a journey through time to Roman and medieval Vienna. Whether legendary buildings, medieval narrow streets or remains of the Roman legion camp Vindobona – every place tells stories from very old times. The game is played in small teams (one team per Booking Referral). At the beginning, the rally management briefly explains the process and provides everything needed for the game : game sheet, card and a bag of letters and materials. Afterwards, the teams move independently from station to station through the city centre and go on a search for clues on site, combining clues and cracking tricky puzzles. The rally management is close by throughout the game, easily accessible and happy to assist if a team doesn't know what to do or questions arise. At the end, the solutions are evaluated, the hidden code is cracked and the mysterious treasure chest is opened with a little sweet surprise.
