Backgammon Pendulum

There are twelve triangles on each side of the chessboard, which are numbered clockwise from the lower right corner with numbers 1 to 24 (the opponent is just the opposite, numbered counterclockwise from the upper right corner, the first point of your own is the opponent's The twenty-fourth point, the second point of one's side is the twenty-third point of the other side, and so on). Each player places two pieces on the twenty-fourth, three on the eighth, five on the thirteenth, and five on the sixth. The first point to the sixth point is called the inner disk, and the seventh point to the twelfth point is called the outer disk. The seventh point is also called the critical point, and the thirteenth point is also called the midpoint.
