The kit has base units (1) including one of two openings (2, 3) that are located in connection with runways (7, 8) and connected with one another. The openings permit a passage of a ball (12) through the units. A clay/tone unit with a toner generation body is arranged between the openings at the base units such that the engendering tone comes in contact with the tone unit by the ball rolling through the base unit. An independent claim is also included for a ball runway.
