In this game, you have to build up a routing of pipes from the fan, within a limited frame of time! As soon as the timer is released, a piece of pipe appears at the left of the menu bar above the image. Put this piece on the grid by clicking on the cell you want it to be. As soon as it is in place, the next piece of pipe appears.
There are two big difficulties in this game. First one is that the available timing is rather short so that you have to be rapid. Second one is that the pieces of pipe to be used are randomized, what can mean to get several pieces you can not use at all! Therefore a small hint: Reserve a part of the board to store the pieces that embarass you. Good work!
