A map quiz of the world's countries on Buckminster Fuller's Dymaxion (Airocean) projection, the globe unfolded into twenty triangles, played by clicking or tapping on the map: answering needs a mouse, touch or pen, there is no keyboard way to pick a country. The first round names a country; click or tap it on the map. The second round names a capital; pick the country it is the capital of. These two rounds leave out 35 small states; the third and fourth round ask all 197, the small ones marked with rings. Then the rounds start over in a new order. Found countries are coloured, a wrong pick shows the name of the country you picked. Zoom with the buttons, a mouse wheel or a pinch; move the map by dragging it or with a two-finger scroll on a trackpad; the plus, minus and 0 keys zoom and the arrow keys move the map.
