The stocks consists of a frame and a bottom element clamped by studs. The internal contour of the frame is essentially conform to the tangential curve of the group of balls. The bottom element is a thin solid sheet, its shape is conform to the outer contour of the frame. The studs are a bit shorter than the diameter of balls in particular so that the internal flange of the frame touches the balls being adjacent to it. The stocks is cut in two halves by a dividing plane. The dividing plane lies on a bisectrix of the stocks and it is perpendicular to the bottom element. The halves of stocks are coupled together at the side cut through by means of a small hinge structure, meanwhile with a lock structure at the tip cut in half. A catching basket is mounted on each halves of stocks at the tip cut in half. Slopes are formed on the two halves of the bottom element in the neighbourhoud of the catching basket, those slopes tilt to lower flate of the bottom element.

The essence of the game is the balls overturned from the stocks on a flat surface have to be picked up one by one by means of the stocks, meanwhile other balls mustn't be moved. The game is played by two players one of them has to collect the red balls and the other the white ones. If the player moves another ball too, the game is the other players turn. The player, who collected his own balls first can pick up the black one. The winner is, who can collect up the black ball.
