Pipe Puzzle· Advanced

Goal

Connect all pipes into a single network from the central source.

How to Play

  • Tap a pipe tile to rotate it 90 degrees clockwise
  • The source and locked tiles cannot be rotated
  • Connect all pipes into one network to clear!

Align Pipe Openings

Adjacent pipes must have their openings facing each other for water to flow. A pipe facing a wall is an error.

Connect All Pipes

Starting from the source, all pipes must be connected without gaps. No pipe should be left disconnected.

Completed Example

  • Tap a pipe tile to rotate it 90 degrees clockwise.
  • All pipes must be connected to the source at the center.
  • No pipe should have an open end facing a wall or empty space.

Tip

  • Start with end tiles on the edges — their direction is easiest to determine
  • Work outward from the source to lock in pipe directions
  • Fix L-shaped pipes first — they constrain their neighbors automatically
