Dig Dug is an arcade game released by Namco in 1982. A popular game based on a simple concept, it was also available as a home video game available on many consoles, and had many arcade and home clones. Dig Dug runs on Namco Galaga hardware.

The objective of Dig Dug is to eliminate underground-dwelling monsters. This can be done by inflating them until they pop or by dropping rocks on them. There are two kinds of enemies in the game: Pookas are round red monsters who look like tomatoes wearing yellow goggles, and Fygars; green dragons who can breathe fire. The player's character is Dig Dug, dressed in white and blue who can make tunnels. Dig Dug is killed if he is caught by a monster, burned by a Fygar's fire, or crushed by a rock.

It takes four 'pumps' with the player's action button to inflate a monster to popping. If left partially inflated, the monster will deflate and recover after a few seconds, but half-inflating is a useful way to stun an enemy, especially to make sure it remains in the path of a falling rock.

The monsters normally crawl through the tunnels in the dirt but they can turn into ghostly-eyes and travel slowly through the dirt.
