Spider's Web is a pac-man variant. The player controls a spider-monster and must gobble up all insects in the top-down maze. Each insect eaten earns the player points. The player is chased by four horrors that must be avoided. When the player eats a green insect he briefly gains the power to defeat the horrors. If the player manages to eat four horrors within five seconds an extra life is won allowing the player to score even more points. There are twelve game variations with different maze layouts, insect locations, and game speeds.
