Was the light bulb invented after or before glasses? With Timeline, learn the answer to this question and thousands of others by comparing your knowledge or hunches to historic reality. At the beginning of the game, players all get the same number of cards representing monuments, inventions, etc. On the back of each card is a date. To begin, one card is randomly drawn from those not given to players. This card is 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 the players. The first player then chooses one of their cards. If the player thinks that the invention on their card came before that of the initial card, the player places their card to the left of the initial card. If they feel that the invention on their card was created after, it is placed to the right of the initial card. The player's card is then turned date-side up. If the player was right, it remains on the table. Otherwise, the card is discarded and a new one must be drawn to replace it. Play proceeds clockwise. 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.
