Players select and place pipe segments, connect them without breaks, score completed paths, and use the next-piece preview to plan the route. Some modes add opponents, obstacles, or time pressure, turning simple placement into a race for space and points.

Build from a flexible area, avoid sealing the board too early, and check the next pieces before committing to a branch. Keep a safe continuation available, use the Japanese menu rules for the selected mode, and save or restart early when a route is irrecoverable.
