Pipes by Michael Kerley – Free

I was literally looking to buy this game last night at $0.99 and now today the full version is available for free. I’ve renewed my interest in the "Pipe Mania" style games so this is excellent timing!

Rotate the pipe segments to connect all the pieces. Easy to learn and very addictive.
