Pipe Puzzle 3: Waterworks

A new sliding-line pipe puzzle. Shift whole rows and columns to align colored routes, then run the water. 10 hand-crafted levels. Free with optional Remove Ads.

Pipe Puzzle 3: Waterworks takes the Pipe Puzzle series in a new direction. Forget dragging blocks. Forget sliding into an empty cell. Every cell on the board now holds a tile, and the move is to shift an entire row or column at once — with wrap-around, like rotating a face of a Rubik's cube. The tile that leaves one edge of the line reappears on the opposite edge. Each gesture sweeps a whole line of pipes into a new arrangement.

Your job is to line up the colored pipelines. Blue water has to reach the blue exit, red has to reach red, green has to reach green. Mix two colors in the same pipe and the run fails. Leave an open pipe end inside the route and the water leaks. Press Run and the network analyzer tells you exactly which colour broke, where, and how.

10 hand-crafted difficulty levels guide you from a calm 4×4 single-colour warm-up to a 7×7 three-colour network with merges and multiple exits. The starting scramble grows with each level — harder boards open further from a solved state, demanding more shifts and longer plans. Hint highlights a tile still off its home position on the route (but disqualifies the current run from records). Undo rolls back the last slide.

KEY FEATURES • Sliding-line mechanic — shift whole rows and columns with wrap-around. Multi-step drags shift several cells at once. • Up to three liquid colors — blue, red, green. Each with its own entry and exit ports. • 10 hand-crafted difficulty levels, designed by hand rather than generated. • Local records — best completion time per difficulty, stored on device. • Animated water — Metal-rendered fluid with caustic shimmer flows along the pipes when you press Run. • Portrait and landscape — play in any orientation. • Light and dark themes plus a high-contrast accessibility mode. • Saved game snapshot — close the app mid-puzzle and Continue picks up exactly where you left off, including the timer. • Undo up to 120 steps. • 22 localizations. • Fully offline gameplay — no account, no servers.
