Pipe Flow: Rotate Pipe Puzzle

Pipe Flow is a pipe puzzle where you rotate pieces to connect the water source to the drain. Your job is to rotate each piece of pipe until there is one unbroken path all the way to the outlet. It sounds simple, and the first networks are. Then the grids grow, junctions start feeding two directions at once, and every rotation that fixes one branch tends to break another. Solving a board is less about speed and more about spotting which connection has to be right before the rest can follow. 124 levels across 12 worlds, each verified as solvable, plus a fresh puzzle every day. You can also play boards made by other players, build your own in the editor and pass them on with a link. Leaderboards and likes show which community networks people actually enjoyed. Stuck? A hint points at the piece worth turning next. No timers, no move limits — the puzzle waits. The campaign and daily puzzle work offline; community levels, leaderboards and likes need a connection. No ads. The optional Thermal Springs world adds 60 new pipe puzzles with a one-time purchase. The original 124 levels, daily challenge and community stay free.
