Was America discovered before Planetary Motion?
Each card has a different discovery and on the opposite side its associated date. A card is randomly selected and placed in the middle of the table, date-side up and is the starting point of a chronological line which will slowly be built by players. The first player then chooses one of their cards and places it before or after the initial card. The player's card is then turned date-side up. If the player was right, it remains on the table. The more cards which are correctly played, the harder it is to correctly place new ones. The first player to get rid of their cards wins.
