Pipeline

A real-time puzzle game, reminiscent of Pipe Dream’s basic idea crossed with a
sliding-block puzzle. The goal is to form a continuous pipeline, conducting
the flow of a red liquid from source to destination. Each level starts with a
grid of jumbled pieces; the player is represented by a movable tile, which can
slide in four directions, exchanging places with adjacent tiles.

Non-player tiles are either blank or occupied by a pipe section: a horizontal
or vertical straight line, a corner, or a cross-shaped piece (which allows
both horizontal and vertical flow). The liquid starts flowing as soon as the
level begins, and the pieces must be re-arranged in real time to carry it
safely from start to finish. Pieces can no longer be moved if they contain
liquid; the round is lost if the liquid reaches a gap, or tries to flow into
an ill-fitting pipe section.

Up to two human players may play simultaneously, using the keyboard.
Pipeline features fifty levels of increasing difficulty, which can be played
in no particular order – some levels add a computer-controlled third “player”
which moves about at random, frequently blocking your movement and destroying
your carefully-constructed plumbing.
