For much of the early 1990s, the Gamesampler, a subset of the Entertainment Pack small enough to fit on a single high-density disk, was shipped as a free eleventh disk added to a ten-pack of Verbatim blank 3.5" microfloppy diskettes. Games on the sampler included Jezzball, Rodent's Revenge, Tetris, and Skifree. A "Best of" disk of several of the games was also available at times as a mail-in premium from Kellogg's cereals.[7]
