A free pipe connection puzzle game with unlimited randomly generated levels. Rotate pipe segments to link the water source to every endpoint on the grid.

How to Play

Choose a difficulty

Pick from Easy (5×5) up to Extreme (13×13) to generate a new random puzzle. Easy starts with many pipes pre-placed.

Rotate the pipes

Click, tap, or use arrow keys and Space to rotate a pipe segment 90 degrees. Plan your connections from the source outward.

Watch the counter

The blue source must connect to every green endpoint. The "Connected" counter shows your progress; pipes glow as water flows.

Use help when stuck

Tap Hint to highlight a tile to fix, or Show Solution to reveal the answer. Replay the board to beat it on your own.

Frequently Asked Questions

Are the puzzles always solvable?

Yes. Every puzzle is generated from a valid solution and then scrambled by randomly rotating some of the pipes. There is always at least one correct arrangement, and no board ever spawns already solved.

I find it too hard. Can I get help?

Yes. Easy boards start with about half the pipes already correct so you have footholds. Each level gives several hints that highlight a tile to rotate, and when you run out the button becomes Show Solution, which reveals and animates the full answer so you can learn the pattern.

How many pipe types are there?

Six: straight (two opposite sides), corner (two adjacent sides), T-junction (three sides), cross (all four sides), source (the water origin), and endpoint (the target to reach).

Does it work on mobile and keyboard?

Both. Tap a pipe tile to rotate it on touch screens; on a computer, use the arrow keys to move and Space or Enter to rotate. The grid scales to fit your screen.
