Carbon Dated
Survey, then excavate. Ten rounds to uncover today's ancient site, and keep it standing.
🎯
Survey (rounds 1–5)
Slide to guess the percentage. Each answer brushes away a layer of the mound. The closer you are, the better the ruin underneath has survived.
⛏
Excavate (rounds 6–10)
Put five finds in order — drag, or tap two to swap. Exact scores full points, one place off scores half. Finds further out knock pieces out of the ruin; at 0% stability it caves in.
🔥
The torch
You get 20 seconds for each survey question and 60 for each excavation round. When the torch burns out, whatever you've set is locked in.

The Museum

Hidden artefact

One of today's finds isn't what it seems.

One of these never existed. Spot it, and you'll uncover what was really buried there.

Phase Two
Excavate
Your survey uncovered the site. Now catalogue five finds each round — anything more than one place out knocks a piece out of it.
