Crazy Loops 2.3

In a game area you have to place different pieces of straight, bended or crossed pipes. On the right there is a conveyor, serving pipes. Take the lowest and place it on the game area. Try to build a locked up system. If one is ready, it will disappear and your score and the game level will increase. Now there is space for further more constructions. Some pipes wont fit together, so you will have to work on more than one system at the same time.
