How to play GeoPaint

Each day brings four country flags, each with one colour missing. Use the Hue, Saturation and Brightness sliders to recreate that colour: the closer you get, the more points you score, up to 100 per flag.

A flag is worth up to 100 points and the score falls off as your colour drifts from the real one. Hue usually matters most, but saturation and brightness decide whether you land in the eighties or the high nineties.

The worldwide puzzle uses more flags than the regional ones, so totals differ between editions. Flags are drawn fresh each day, and the Europe, Americas, Africa and Asia versions stay within their own continent.
