Dig Dug

Each level is a cross-section of dirt with tunnels dug in real time as the player moves.

The two types of enemies encountered are Pookas, round red creatures wearing goggles, and Fygars, green fire-breathing dragons.

Both pursue the player through tunnels, and after a few seconds of losing sight of the player, they can transform into ghostly forms to move through solid earth until they reach another tunnel.

To defeat enemies, the player carries an air pump that can be attached by pressing the action button.

Pumping inflates the monster until it bursts, awarding points.

Pumping can be interrupted, but partially inflated enemies will revert to normal and continue attacking.

An alternative method of attack is luring enemies under large rocks scattered throughout each stage.

Digging beneath these rocks can cause them to fall, crushing anything below, including the player.

Rocks falling also open tunnels, and dropping multiple rocks in a stage grants bonus points.

Scoring incentives are built into the system.

Vegetables occasionally appear in the middle of the screen once two rocks have been dropped in a round.

Collecting these vegetables grants bonus points, and the type and value of the vegetable increase in later rounds.

Bonus points are also awarded for consecutive ghost kills or for crushing multiple enemies with a single rock.

Each round ends when all enemies have been eliminated.

Enemies increase in speed as stages progress, and Fygars add the additional threat of breathing fire horizontally across tunnels, which can instantly defeat the player.

Later versions and home releases varied in presentation and features.

The arcade original allowed two players to take turns, while console and computer ports often adjusted graphics and sound to suit hardware limitations.

Some versions altered maze size, e

Dig Dug for Game Boy is currently worth €33.32 loose, €128.52 complete in box, and €295.71 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Dig Dug, loose is €33.32 and CIB is €128.52 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.

The PAL version of Dig Dug is currently worth €33.32 loose, versus €19.64 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
