Order by the year each was invented or first sold. You place all 50 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 an ordinary object you have probably used this week, from fasteners and tape to kitchen gadgets and things that live under the sink. The inventor or company sits under the name, and the hidden year is when it was first sold, or when it was patented if no sale date is on record. One card starts on the line with its year in view. Slide each new card into a gap. Pick right and the year appears. Pick wrong and the card drops into its true spot, and you lose one of three lives.
The hard part is that these things feel like they have always existed. Some household staples turn out to be surprisingly old, while others that seem timeless only reached shelves within living memory. The early cards are mostly simple patents, and the middle years fill up with plastics, adhesives and postwar kitchen conveniences. Late cards lean toward infomercial hits and things you saw go viral. Trust the materials: what an object is made of often tells you more than how familiar it feels.
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 50 cards you might be dealt, with 22 more in the deck. Their values stay hidden until you place them.
