The Martian game of Yano is usually played with six players. Counters or oval metal coins change hands between winners and losers. Each round of Yano is played with six spheres, numbered from one to six. The regulation Yano court should be level, with a hard, smooth surface.
Most courts feature a containing barrier and banking wall behind the holes area.
The traditional court is laid out with seven holes, six in a line parallel with the Players Line. The diameter of the holes is two inches. The distance between the edges of the holes is two inches. A line passing through the centers of Holes 1 to 6 is a distance of 15 feet from the Players Line. For each play the spheres must be mixed and redistributed.
