Order by the year each first happened. You place all 44 cards on one timeline, one at a time. You start with three lives, and ten right in a row wins a lost one back.
Each card is a first that everyday life now takes for granted: the first photo, stamp, traffic light, credit card, cash machine, email, text, web page and tweet. Under the name you will see where it happened or who did it, and you sort the cards by the year of that first. One card starts on the line, year showing. Choose a gap for each new card. If you are right, the year appears; if not, the card still lands in its true place and you lose one of three lives.
The early cards are about streets, shops and post, and the later ones move onto screens and phones. Digital firsts come in a rush, often only a year or two apart, so think about which tool had to exist before the next one could. Many of these firsts happened long before the thing went mainstream, which is why a gadget you remember getting as a novelty may have had its debut much earlier.
Want a longer game? On the deck tree you can tick this deck alongside any other one measured in release years and dates, and they shuffle into a single timeline together.
Here are 28 of the 44 cards you might be dealt, with 16 more in the deck. Their values stay hidden until you place them.
