The Manhole is brothers Rand and Robyn Miller’s first release before they went on to design the best-selling game in PC history (hint: it rhymes with "gist"). It is also noteworthy as the first product ever to be released on the new medium of CD-ROM — way back in 1987! Unlike that overrated collection of puzzles set in an empty world, The Manhole is teeming with lively cartoon characters that kids will like, as well as many educational tidbits disguised as mini-games to be discovered.
