About Pipe Line
You just have to touch a dot and drag it another same colored dot to make a link.
Do this for all the same colored pairs of dot.
İmportant: "A level is considered clear only when the whole board is filled with the pipes connecting same colored dots"
Keep in mind that links will break if they cross or overlap.

The game has some bugs, the level won't finish sometimes. Not to mention that it is a complete clone of a well known game.
