Reception
Forrest Johnson reviewed The Toughest Dungeon in the World in The Space Gamer No. 35. Johnson commented that "Do you enjoy rolling dice for hours on end, even knowing the probability of a favorable outcome is very slight? [...] If you have better things to do with your time [...] there are plenty of other games on the market."

Anders Swenson reviewed The Toughest Dungeon in the World for Different Worlds magazine and stated that "In evaluation, this is a well done adventure with a crazy theme that everybody should try. Pity the poor troll, cowering in the dank depths, trying to get a small fortune together so he can escape to the outside world, free from the clutches of dungeon existance [sic]! It may make you want to take a troll to lunch."
