Pipe Flow

Start with the core loop

Play Pipe Flow free online. Rotate pipe tiles to connect the source to the drain before the water flows, across rising levels.

Tap a tile to rotate it clockwise. Arrow keys move the cursor; Enter or Space rotates.

Build a better run

Boards expand over successive levels while the timer and scoring reward fast, economical rotations.

Play with intent

Trace backward from both endpoints, solve forced edge connections first, and avoid rotating already connected sections.
