World Imposter

World Imposter is a choropleth game: a map where darker shading means a bigger number. Each day picks a region of the world and a real statistic from open data, labelled above the map with its source: on 20 October 2026 it was the share of electricity that comes from hydropower across the Americas, darker meaning more.

One country's colour is wrong. Its fake number has been chosen to sit comfortably among its neighbours, so you cannot spot it by colour alone: you have to know, or reason out, which country would really be lighter or darker than it looks.

You tap a country and press Accuse. A wrong guess hatches out more countries that are telling the truth, the same ones for every player, so the field narrows. You have six guesses, and the fewer you need the better. At the end you see the imposter's real number and why it stands out.

Maps can be zoomed and panned, names turned on or off, or the countries shown as a list. Puzzles are numbered, and the past seven days sit along the top to catch up on; a catch-up counts in your log but not your streak. You can share a row of squares for your result. There are no ads and no sign-up. Axisless also makes Daily Shade, Keysweeper and other data visualisations.
