Pipeliner

A Pipe Dream clone. Each level of this abstract puzzler challenges the player to set up a network of pipes to allow an unspecified substance to flow through as many of those as possible. The pieces are offered in random order, and there are seven different types - straight lines going horizontally or vertically, corners rotating in each of the four directions, and cross-over pieces which carry the liquid straight across horizontally and vertically. Each of these can be entered from either side. When the liquid hits a gap or a piece that the previous piece can't flow into, the pipe is finished.
