To crown the game theory lecture, Dr. Friederike Stoll and Prof. Michael Eisermann auctioned off valuable items on Friday, 7 February 2020. The auction took place during the weekly Casino Royal, where game theory was tested experimentally. In addition to lecture and study posters, various calendars, an uncensored version of the departmental announcement "Klopapier" and a glass full of 1 and 2 cent pieces donated by staff and students of the department were auctioned off. The highlight was the auction of one Euro. Anyone who was there is still amazed today.
