Dig Dug/Walkthrough

The pump stall
Having two or more Pookas on your tail can present you with a problem: if you try to explode one Pooka, the next one in line will pass right through his inflated friend and get you. The problem is that your pump line remains hooked to the first Pooka, and the other Pooka is not affected by your pumping.

The solution is to turn away from the first Pooka, breaking the connection, and instantly turn back and start pumping again. Your renewed pumping action will affect the closest Pooka. Meanwhile, the other Pooka will be immobile until he has completely deflated. Repeating the process one or more times may keep Dig Dug safe while defeating the enemies.

Using rocks
The rocks are a great asset, once you understand how to use them. Some important observations about the fine art of rock-dropping follow:
 * 1) Never turn down after passing under a rock; it will fall on your back.
 * 2) You can hold a rock in place by staying directly under it. Wait there until a Pooka or Fygar comes up from below, move to either side, and the rock will crush him.
 * 3) Rocks can fall through thin walls of dirt, so you can drop a rock on a Pooka or Fygar without ever entering his cave.
 * 4) Pookas and Fygars will sidestep a falling rock if they can. Try to time your drop so that there isn't a close escape route for the intended victim.
 * 5) As shown in the image, dig long vertical tunnels under the rocks. Make sure you do not dig to the left or right as you carve the tunnel - that will allow the Pooka or Fygar to just escape the falling rock when it is dropped.

Be greedy near the end
When time is running out, and the last Pooka or Fygar heads for the surface, grab whatever points you can. This may mean eating the vegetable bonus, or waiting on the surface for the fleeing enemy. If you're too far from the surface to get there in time, just keep burrowing and score a few extra "dirt points". These free points can make a difference - next time your game ends 10 points short of an extra life, you'll probably wish you had been more greedy.

The great escape
Unlike almost any other maze game, Dig Dug provides you with a way out of the seemingly hopeless predicament of being stuck between two approaching monsters. One possibility of course is to simply burrow away to the side. But if there isn't enough time for that, or you're stuck against a rock or the edge of the screen, you can still escape; just go through one of them. Hit a Pooka or Fygar once or twice with the pump button, and you can pass safely through him, as long as you do it before he deflates. The trick comes in handy very often - don't forget it.

Ender's Loop
To beat any level of Dig Dug, one must take advantage of the AIs. One way to do this is to dig out either left or right from the starting position, dig up a short ways from your starting position, turn around and continue digging out your initial tunnel, then go up again (this time further away from your start position) until you are higher then the end of your first upward tunnel. Continue from here in the opposite direction of the direction you went at the beginning of the level, until you have almost reached the vertical tunnel that exists before you start any given level of the game. Create a thin wall between you and the vertical tunnel, and pump enemies up as they pass by.

Free digging secret
It is best to try this before round 36 since everything speeds up.
 * 1) Get the game down to two Pookas. If you only leave one, it will escape thus ending the round.
 * 2) Get a Pooka to follow you, inflate as necessary to delay him a little.
 * 3) Right when you are next to the rock, inflate the Pooka once to just delay him. When he moves at your character again, move under the rock.
 * 4) Quickly turn around and start pumping the Pooka up. Using the delay of the rock dropping, you should be able to cause the Pooka to burst at the same time the rock drops on him.
 * 5) If you are successful, then the other Pooka will disappear and you can amuse yourself digging out tunnels all day long in the dirt. To return the game back to normal, drop another rock and you will proceed to the next round.

Late game

 * Score: Once you have made it to 999,990 points, your score will roll over to 0. No additional extra lives will be awarded to you after this point either, unfortunately.
 * Flowers: The flowers that indicate the rounds on the surface of the ground will stop updating at round 69, but the indicator at the bottom of the screen will continue updating until round 99 before rolling over to round 0. At this point there will be no flowers. Once you have made it to round 101, the flowers will start updating again.
 * Slow enemies: In the original arcade versions of the game by Namco, the Pookas and Fygars will slow down once you have made it to round 124, and again once you have made it to round 136. This reduction in speed will continue every twelve rounds until you have made it to round 256 (which is the "kill screen", see below).
 * Kill screen: In the original Namco versions of the game, the game has a "kill screen" on round 256, which is registered by the game as round 0. The round starts with a Pooka directly on top of Dig Dug, which will cause the player to lose all of his remaining lives very quickly.  Atari revisions of the game correct this problem.
