Pipe Puzzle 2: Waterworks

New in the Pipe Puzzle series: a sliding-tile twist. Slide pipe tiles into the empty space, line up every colored route, then run the water. 10 levels, fully offline.

Pipe Puzzle 2: Waterworks turns the classic sliding puzzle into a plumbing challenge. Every level is a grid of pipe tiles with one empty space. Slide tiles into the gap to rebuild the network, connect each colored inlet to its matching outlet, then press Run to send the water through.

If every route is sealed and no colors cross, the level is solved. If a pipe is left open or two colors meet, the run fails — rearrange and try again.

— HOW TO PLAY — • Tap a tile next to the empty space, or swipe it, to slide it into place • Rebuild the board until each colored entry reaches its exit through a sealed pipeline • Press Run to test the network and clear the level • Beat your best time on every difficulty

— FEATURES — • A sliding-tile puzzle built around pipe routing — easy to learn, tricky to master • Up to three liquid colors (blue, red, green), each with its own inlets and outlets • Locked tiles on harder levels force you to plan your route around them • 10 difficulty levels, from a gentle 4×4 grid up to a 7×7 multi-color network • Local best-time records for every difficulty • Hint button when you get stuck (hint-assisted runs don't count toward records) • Undo any slide • Continue right where you left off — your puzzle is saved automatically • Light and dark themes, plus a high-contrast mode • Music, sound effects, and haptics — all adjustable • Plays fully offline.
