Pipe Challenge

In Pipe Challenge you can try to solve all kinds of challenging pipeline puzzles. Rotate the pieces of the pipeline to make them all connect. You must connect the two dots and all the pipe segments with each other, although not every piece has to be part of the line connecting the two dots. You can also lay out stray pieces in a loop, just as long as there are no open ends left. Look carefully at the scattered pieces. Can you figure out these tricky puzzles?
