How to play

Sixteen moments from history, four eras. Find the four events that belong to each span of time. A new board arrives every day at midnight.

Tap four events you think happened in the same era, then press Submit. Get it right and the group locks in with its dates.

Today's four eras are listed above the board, oldest first, so you know what you're sorting into.

From widest to narrowest

A broad era, like the Middle Ages

A century, like the 1600s

Half a century, like the late 1800s

A single decade, like the 1980s

A wrong group costs one of your four mistakes. One away… means three of your four belong together. Those three keep a border in their era's colour, so you know which ones go together.

Stuck? You get one hint per board. It tells you the era of one event from the trickiest group still to find.

Tip: start with the era you're surest of. Fewer events left makes the narrow decades easier to spot.
