Unlabeled

Unlabeled gives you four charts, one at a time: line charts, bar charts and other shapes, each with its numbers on the axes but no words. Your job is to work out what each chart measures. You tap an empty slot above or below a chart and choose a label from the list of ten. The numbers are your clues: an axis running from 1900 to 2025 is almost certainly Year, and the size and shape of the data tell you the rest.

Once all eight axes have a label you press Check. Correct labels turn green and lock in place; wrong ones come back to the list, and the game tells you how many you have right and how many tries remain. You have four tries in all, and two of the ten labels are decoys that fit no axis.

The four charts of a day are linked. When the labels are done, the game asks you to put the charts in order as a chain, each one driving the next, with a Check order button and a Skip if you would rather just see the answer.

Every puzzle is made from open data with its source named, and an archive and a sources page list past puzzles and where their data came from. Unlabeled is made by Andrew Antes and launched in autumn 2026. It can be played in English, Spanish and French, there is no account to make and nothing to pay, and an optional email arrives each morning when the new puzzle is ready. It suits players who like reading graphs, and teaches you a little about the world each day.
