Wall Pipe

Wall Pipe is one of many Pipedream / Pipemania / Oilswell type games released by Soleau Software. This game plays pretty much the same as the games previously mentioned: Lay out pieces of pipe so that the oil continues to flow. You're given 30 seconds before the oil starts moving. The interface is a bit confusing to me: You need to click the mouse to select the next piece, which then disappears, so you'd better remember what type of piece you're placing.
