Quality standards for punchboards

A manufacturer of punchboards shall print a game serial number on all punches and manufacture, assemble, and package a punchboard so that winning punches, or approximate location of winning punches, cannot be determined in advance of punching the punchboard, including any patterns in manufacture, assembly, packaging, or markings. Winning punches must be randomly mixed among all other punches in a punchboard and between all other punchboards.
