Game description

Game rules
 * Each player on his turn adds a new point. The point must prolong the existing Polyline (or start the Polyline, if it doesn't exist).
 * The resulting Polyline must be non-interrupted and each move can be taken in any of end of the line.
 * The player, which locks the line (the point is set on the polyline), wins.
