In ANNO DOMINI it is not about exact knowledge. Because who knows whether the "first German kindergarten" existed before or after "Pumuckl becomes visible to Master Eder". In turns, each player adds a new event to the chain of mostly curious occurrences and tries to be the first to get rid of their cards. If a player doubts that the event cards are in the correct order, the hour of truth strikes: The cards are turned over and the chronological order is checked against the given date. If something is wrong, the player who was directly before gets penalty cards. However, if everything is correct, the doubter has to draw penalty cards.
