Deckades shows you a film, song, invention, or historical event, and you slot it on a growing timeline by the year it came out or happened. It gets harder with every card as the timeline gets crowded, and you only get 3 lives to place all 10 cards. The daily puzzle is the same for everyone, with a share grid at the end so you can compare. There are 50 themed decks: Disney & Pixar, Hip-Hop Chronicles, Blockbuster Cinema, World History, etc.
