A series of digging-based maze games. The objective is to get the protagonist (variably named Taizo Hori or Dig Dug) to eliminate all enemies, usually consisting of tomato shaped Pookas and dragonic Frygars, through the use of an air pump. The series later spawned an action-puzzle based spin-off, Mr. Driller which featured the son of the first game's star.
In addition to spawning the spin-off series Mr. Driller, elements from Dig Dug have appeared in numerous other games, such as cameos in some Pac-Man games. The Pooka enemy from Dig Dug appears in Smash Run and cameos in Namco Roulette.
The level start, main theme, and level complete music from Dig Dug appear in Namco Arcade '80s Retro Medley 1.
