Imposter

1. Every country is coloured by a real number. Darker means more.
2. One country is lying. It wears the colour its neighbours would have, so it blends in. Look for the country you know should stand out, and doesn’t.
3. Tap a country, then Accuse. After a wrong guess, more honest countries are cleared (hatched) for you, the same ones for everyone.
4. You have six guesses. The fewer you need, the better.

Zoom and pan like any map. A new Imposter every midnight.
