Pipe dream

The pieces of pipe you lay are each the size of one grid square and they appear one at a time in a random order. They include horizontal pieces, vertical pieces, corners, crossroads, and small reservoirs (which buy you a little time when the flooze is on its way!). Much like Tetris with its ‘next piece’ indicator, here you get to see the next five pipe pieces in the queue so you can plan ahead to some extent, but if you get any pipe pieces you don’t want, you can dump them elsewhere on the grid.
