Pipe Connect is a rotation logic puzzle. Most tiles turn 90 degrees when you tap them. The source and tank stay fixed. The board lights when a continuous path really exists — the game searches connections rather than counting how many times you turned a tile. Five boards make a full run. After a link you tap Next level.
Tap or click a pipe tile to rotate it. Source and tank do not turn.
Connect source to tank on all five boards. A lit path means the link is real.
Drop crates and keep the beam level.
