Dragon Island is a simple game that bears some similarities with Hunt the Wumpus. The goal is to slay a dragon with a spear. Each turn the player may throw his spear in one of ten caves. If the dragon is in the chosen cave he dies, if he's in an adjacent cave he'll snort. The dragon can also change cave. Between each throw the player must retrieve the spear. If the dragon in the mean time moved into the cave, the player dies. The player also dies if he or she fails to kill the dragon before the clock strikes eight.
