Line Puzzle: Pipe Art — How to Play & Free Pipe Puzzles to Try
Line Puzzle: Pipe Art is a free mobile puzzle game by BitMango in which you connect matching-coloured pipes so they fill the whole board without overlapping — a relaxing, connect-the-colours "flow" puzzle with well over a thousand levels. If you enjoy it, you can also play a free pipe puzzle in your browser here — the rotate-to-connect kind, with no install.
Below is what the game is, how to play it, how it relates to other pipe puzzles, and the tips that beat hunting for answers level by level.
What is Line Puzzle: Pipe Art?
Line Puzzle: Pipe Art is a connect-the-colours flow puzzle: you draw a pipe between each pair of matching colours so the pipes cover every square and never cross. It is published by BitMango and plays at your own pace — there is no timer by default, though an optional Time Attack mode adds one.
Its main features are:
- More than 1,000 levels that scale from tiny starter grids to dense, large boards.
- A relaxed, no-penalty pace — take as long as you like, with an optional Time Attack mode if you want pressure.
- Daily puzzles and bonus rewards to bring you back each day.
- Offline play on phone or tablet, free with ads and optional purchases for an ad-free board and hints.
It is available on the App Store, Google Play, the Amazon Appstore and the Microsoft Store. (We are not affiliated with BitMango — this guide just explains the game and points to free browser options.)
How to play Line Puzzle: Pipe Art
- Find each colour pair — every colour appears exactly twice, and your job is to join the two.
- Draw a pipe between them by dragging from one endpoint to the other.
- Cover every square — a level is solved only when the pipes fill the whole grid.
- Never cross or overlap — if two pipes would share a cell, one of them is routed wrong.
- Use undo and hints to back out of a dead end instead of restarting the board.
Is it the same as a "pipe puzzle"?
Line Puzzle: Pipe Art is the connect-the-colours type of pipe puzzle, not the rotate-to-connect type. Both get called "pipe puzzles", so it helps to know the difference:
| Type | What you do | Examples |
|---|---|---|
| Connect-the-colours | Draw paths linking matching endpoints to fill the grid without crossing | Line Puzzle: Pipe Art, Flow Free |
| Rotate-to-connect | Turn fixed pipe tiles until every pipe joins one connected network | Pipe Puzzle, Net, FreeNet |
For more on the draw-the-path family, see our flow puzzle guide; for the turning-tiles family, see what a pipe puzzle is.
Looking for answers or a walkthrough?
The fastest way to beat the levels is the technique, not a list of solutions. With more than a thousand boards, looking each one up is slower than learning the method:
- Start at the corners and edges — a colour in a corner usually has only one sensible route out.
- Connect the most boxed-in colours first — the pairs with the least room force the rest.
- Never strand an empty cell — leave no square that no pipe can legally reach.
- Fill the grid completely — if a square is empty, a path needs to detour through it.
The same edge-first logic powers our guide to solving a pipe puzzle.

Frequently asked questions
Is Line Puzzle: Pipe Art free?
Yes. Line Puzzle: Pipe Art is free to play with ads. Optional in-app purchases remove the ads and add hints, but you can finish the puzzles without paying.
Who made Line Puzzle: Pipe Art?
It is published by BitMango, a casual-puzzle studio, and is available on the App Store, Google Play, the Amazon Appstore and the Microsoft Store. We are not affiliated with BitMango.
Is Line Puzzle: Pipe Art the same as Flow Free?
They are the same family of puzzle. Both are connect-the-colours flow puzzles, descended from Numberlink: you link each pair of matching endpoints with a path so the paths fill the whole grid and never cross. The publishers and artwork differ, but the core idea is the same.
Can you play Line Puzzle: Pipe Art on PC or in a browser?
It is a mobile game with no official browser version. You can run it on a PC through Google Play’s PC option or an Android emulator. If you want a pipe puzzle to play directly in your browser with no install, you can play our free rotate-to-connect pipe puzzle instead.
Where can I find Line Puzzle: Pipe Art answers?
Walkthrough videos and answer pages exist, but the game has well over a thousand levels, so memorising solutions is slow. Learning the technique — connect the most constrained colours first and never strand a cell — beats looking up each board.
