Play Tube Online

Tube is one of those early MS-DOS puzzle games that came out without much fanfare, part of a broader wave of simple, focused titles from the late 80s and early 90s. It doesn't carry a famous developer name or publisher, but it fits right in with the kind of thoughtful, uncluttered design that made many DOS games quietly memorable.

You control a series of disconnected pipe segments on a grid, rotating each piece to form a continuous path before a timer runs out or liquid spills. The main objective is to complete each pipe route without leaks, under increasing time constraints and complexity. Signature mechanics include the ability to only rotate one pipe at a time, often under a ticking clock, and later stages that conceal pipe connections until you're nearly out of time. The pacing is tense but methodical, demanding quick decisions and spatial awareness. It feels like walking a tightrope between calm logic and rising panic.

Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
