Pipe Mania becomes a maddening and frantic game of strategy and crowd-control as the timer ticks down and the flow trickles out. For a simple-seeming puzzle game, it's stupidly engrossing. The difficulty is a bit of an issue though. As the game continues, you'll find the demands it places on you become greater, and the unpredictability of the different pieces you receive becomes frustrating.
This isn't so bad, though, as you can skip levels at will, but for the points-purists out there, you'll want to play and complete levels with the best score you can muster. And that's the beauty of Pipe Mania – it's simple, addictive and fun in a way that all portable puzzlers should be.
