PornPipe is a Pipe Dream variant with an adult theme.

The player should construct the pipe (simulating the penis) to be long enough to ejaculate the sperm after defined time. While the "liquid" is flowing in the sections of "the pipe:, parts of a "porn video" (looping animated images) will appear at the bottom left corner. Once the video is fully revealed, or the final part of "the pipe" is reached, the level is completed.

There are four levels with four different female models seen in background of playfield. The mechanics of pipe construction also varies. Pipe may be constructed with parts given to the player in random order, or it may be adjusted with parts already scattered on playfield.
