While other versions of Timeline are focused on certain elements (events, inventions, discoveries, etc.), Timeline Classic is a highly engaging version that encompasses multiple themes in one convenient package. Was the pencil invented before Washington crossed the Delaware? Each card depicts an invention on both sides, with the year in which that invention was created 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.
