Timeline is a card game played using 220 cards. There are lots of different versions – historical events, art history etc. Each card depicts a historical event, invention or discovery on both sides, with the year in which that event occurred, invention or discovery was made on only one side. Players take turns placing a card from their hand in a row on the table. After placing the card, the player reveals the date on it. If the card was placed correctly with the date in chronological order with all other cards on the table, the card stays in place; otherwise the card is removed from play and the player takes another card from the deck.
The first player to get rid of all his cards by placing them correctly wins
