XPIPE, GAMES, Build pipe for the fluid to flow through OBJECT_OF_THE_GAME When the fluid flows through all the pipe you've built, the level is over. If the fluid went through enough pipes before the end of the level, you get to move on to the next level. Otherwise, "Game over!" Fluid will start to flow though the only pipe in the large grid after a short while. (See the status window to see how long until the fluid starts to flow.) On the left, you will see a small window with four pipes. When you click in the main window, the lowest pipe is placed where you clicked. The other three pipes then move down and a new pipe is placed at the top of this "preview" window. The lowest pipe in the small window is always the next tile that will show up on the big grid. The next higher pipe will show up next. Since there are four pipes in the preview window, you always know what the next four pipes will be. If you manage to fill enough tiles, you get to move on to the next level.
