The object of the game is to connect a pipeline from an oil tank somewhere on an island to a filling station on the edge of that island so a cargo ship can pick up the crude and carry it off to billions of anxious consumers. The playing field is a grid and each square can take one piece of pipe. The trick is that the different pipe shapes crosses, straight pieces, bent pieces come in random order so you have to work with what you are given.

Sound simple? Well, it might be except for a few things. First of all, there's a time limit on each level. An experienced player will find it easy to complete a pipeline in the allotted time but a beginner will most likely struggle.

Also, each level has a set of goals that must be met. The player must get a certain amount of points (points are awarded for time left over and for the number of pipeline pieces laid) and must build a certain number of "crosses". As I mentioned, some of the pipeline pieces that you are given to work with are in the shape of crosses. This means that instead of just connecting them on two sides, you can attach pieces to all four sides. If you do this correctly, the oil will turn as it flows through the finished pipeline. You also get bonus points for each "cross" the oil flows through.

After you complete the pipeline, points are deducted for any pieces you have placed that are not part of the main line. And on the higher levels there are occasional obstacles (rocks and bushes) which you can not place pieces on. (Actually, the whole game takes place on islands which are sometimes irregularly shaped so you do not even necessarily have a square playing area.)

Your system should be able to display at least 256 colors, or the graphic isn't very good.
