In this game similar to Pac-Man you steer a drilling head that needs to collect all points in the aisles of the level. During this, enemies move horizontally on each plane. You can "eat them" with the drilling head, but if they touch the pipe the player will lose a life. So if an enemy gets too close to the pipe, you need to quickly climb up again. The difficulty is to choose the paths in dependence of your current position, so that you have enough time to advance to the deeper layers.
The screen shows the oil refinery in the upper third and below this the soil with the aisles. Each of the eight levels is designed differently and caringly. In the refinery the available time and the drilling heads that are left are shown in the upper left and in the upper right you can see the points. On each plane there are two individual enemies. Unfortunately, the music only consists of a simple bass riff, but there are plenty of sound effects.
- You move the drilling head inside the aisles with the directions of the joystick.
- With the fire button you quickly draw it back.
Number of levels
After finishing the 8 levels they repeat and the enemies get faster each round. When you have played through all levels three times it gets as fast as in the first round.
The first three rounds can be chosen before the game as difficulty grades:
Items, enemies and points
|Item||Description / Info||Points|
|Simple dots (Oil Pellets)||When you have collected them all, you automatically reach the next level.||10|
|Big dots (Petromins)||Special Oil Pellets, which temporarily slow down the enemies.
There is one per level, it does not need to be collected to end a level.
|Cups (Goblets)||Do not kill when they touch the pipe.||1.000|
|Enemies||Description / Info||Points|
|Land Mines||Kill when touched with the drilling head, not with the pipe||—|
|Monster (Oozies)||Kill when touched with the pipe||20|
Points for the monsters
The game area is divided into 18 lines. At the start of the level the drilling head is in line 1. Except for a small shaft in level 7 there are no aisles there. Line 18 forms the lower border of the game area. The lines 2 and 4 to 17 can be occupied with aisles in which the monsters appear. In line 2 you get 20 points per monster, in line 4 you get 40 points and in line 5 you get 50 points etc. until line 17 with 170 points per monster. Line 3 is not ocuppied in any level, so that no monsters appear in line 3. So there are no monsters that get you 30 points.
- You start with 3 lives.
- Every 10.000 points you get another life.
- As all the creatures always enter the game area from the border of the screen, you should try to stay in the middle with the drilling head, or respectively always choose the passage in the next deeper level that is closest to the middle of the screen, so you have more time to react and draw back the drilling head.
The disadvantage here is, however, that longer paths are created and it can take longer until the drilling head is drawn back.
- Sometimes it can be worth keeping an Oil Pellet. If you still have enough time left, it can be used to collect Oozies or Goblets, before you finally end the level. By this you can use the available time and yet get some extra points especially in lower levels.
You should hereby look out for the time and not take great risks, because the 99 seconds that you have after losing a life are usually not enough to collect enough points with which you can compensate for a lost live.
However, it is possible with this tactic to acquire an additional life after two levels.
- The version by "ASS" has next to a cheat mode also a saveable highscore liste.
If you decide to cheat, the time limit (99 sec./life) is left out and you have unlimited time.
The game results in the cheat mode are saved in a separate highscore list.

Artur83: "Graphics and sound do look their age, but the game is rapid and challenging. A very good game principle with a great fun factor".
H.T.W: "A real classic, ingeniously simple but mind-boggingly fast, challenging and motivating. Just great, this game...".
blubarju: "There is nothing to object to in this game. An all around successful game that is fun. 7 points from me".
ZeHa: "One of my absolute favorites, such a great concept and I also love the mood created by the background music and the sound effects".

- Note from CW: The fourth round in my game starts with the following: In the first 3 levels everything moves in slow motion, then from level 4 onwards everything is even faster than in the third. Level 5 can't be done (lost 23 lives). Score by CW: 275930 (Round 4, level 5)
- Note from Mindless: my Oils Well steadily increases speed over the first 3 rounds, as usual. In the fourth round the first 3 levels are super-fast (creatures move the same speed as your drill head), then the remaining 5 levels are like round-3 speed. Round 5 has the first 3 levels super-slow (creatures barely move), and the remaining 5 levels are super-fast. I consider passing 5 rounds as "winning" the game (and thus posted my score above from that point), because from round 6 onward it appears every level is super-slow.
