Connect Pipes Game

Connect pipes rules

• Connect each pair of same-colored dots with a line.
• The level is clear once every pair is connected. Empty cells can stay empty.
• Lines cannot cross.

A finished pipe joins one pair and then sits still. The other pipes route around it. Because empty cells are allowed, you are not pushed into a dead end just to cover space. Occupy a cell only when some pair needs it.

The pipe may turn as often as you like. It may not step diagonally, and it may not land on a cell that already holds another color. Side-by-side pipes are fine. Sharing a cell is not.

How to draw the pipe

1. Press one end of a color and drag through empty side-neighbors.
2. Release early if you want the pipe to stop. Pick up the open end on the next drag.
3. Press any cell of that same pipe to retract the end back to the cell you pressed.
4. Use Undo for one step, or Restart when you want the board empty again.

If the line stops in front of a blank cell, that cell is not a side neighbor of the current end, or another color already owns it. Move through the free cells that do touch the end. Hint lights the next three cells of one working route, in order, and then stops for that attempt.

Connect pipes questions

What counts as connecting the pipes?

One continuous path from one end of a color to the other end of that same color. When every color has that path, the level is clear, even if some cells are empty.

Why did the pipe refuse a blank cell?

The blank cell was not directly up, down, left, or right of the open end, or another color already occupied a cell you tried to cross. Drag along the free neighbors.

Can two pipes run next to each other?

Yes. They can touch along an edge for as long as you like. They cannot occupy the same cell, and one cannot jump across the other.
