Castle Dungeon is an adventure game for the Commodore 64 that was published in the June 1984 issue of the Compute's! Gazette. You are in a dark castle with nothing but a weak lantern. An evil wizard has set up three bombs that are set to explode and destroy the castle. Your task is to find and defuse these bombs before they blow up. Be careful, however, for there are blind guardians that can kill you and pits that you can fall to your death in. Thankfully, there are items you can find to get around those obstacles.

In this run, nymx completes defuses all the bombs in record time by getting an RNG seed that generates a level that has all the bombs close to each other without any obstacles in the way.
