One Amazon reviewer says:
I don’t know if the original PIPE DREAMS distributed by LucasFilms Games in 1990 was the very first, but it certainly illustrates that the puzzle theme has been around for a long time. PIPE PUZZLE PREMIUM brings this classic style to Android users in a Portrait only orientation, phone friendly game with polished Unity-based graphics, soothing New Age soundtrack, and potentially maddening difficulty.
