Mark off a bite of their country on squared paper, then throw the eraser.
A phone each. Find a table with other players, or start a room and send friends the link.
This is a game Turkish schoolchildren played on squared paper, with the silgi: the two-tone eraser that was red at one end for ink and blue at the other for pencil. You drew a country, split it between everyone at the desk, and then argued over it one flip at a time.
Mark off a piece of somebody else's land, then throw the eraser. Red side up and it is yours. Blue side up and you hand over the same amount from your own side.
The map has ground worth wanting: hills, a river with two fords, a capital on a flag, and twelve rounds of weather. Any seat can be a person or the computer, so you can pass one phone around or play alone.
A number puzzle where you draw each region yourself. New board every day.
Hold on. Don't get rugged.
Stand on a jetty, charge a throw, and chase the stone down the valley.
