Case file · today

Somewhere on Earth, a place changed.

Find it. Read its timeline. Then decide whether what people say about it is true.

  • 01 Pin the place on the globe. Faster is better.
  • 02 Put four satellite images in order.
  • 03 Judge the claim. Your verdict is sealed until tomorrow.

What got in your way?

How it works

01One place. Three steps.

Every day a real place where nature changed. Pin it on the globe, put four satellite images in order, then judge a claim about it. About three minutes.

02Seeds are just points.

Seeds show how well you played. They have no monetary value and can't be bought, sold or exchanged.

03Accuracy is what counts.

Your verdicts are checked the next day. Accuracy comes only from those verdicts, not from speed or seeds. Later, the most accurate players will be invited to paid field tasks: recording nature sounds near where they live.
