"Xmas Pipes" Game

Xmas Pipes is a fascinating logic puzzle game in which you have to think hard about how to deliver toys and presents to the Christmas tree. The thing is that the Christmas tree is on one side of the pipe, and on the other side are the decorations for it. In between are many different disparate pieces of pipe. You need to connect the pipes so that you have a complete closed system. Only by doing this, you can open the flap so that the toys fall down the pipe you built and reach the Christmas tree. Then it will glow, and you can proceed to the next level. Will you be able to complete all 30 levels, which will become more and more difficult each time?
