In ColorEx you should change the position of pipes to fit it. The colorful liquid must fill up into the right container.  You can fill the bottle with extraordinary ways of avoiding even pipes. Each player can fill the pipes in his own way.  Firstly the player should turn pipes to fit them in best positions and after turn on liquid, if the plan is enough good the colored water will get into the right glass flask. Usually you should fill 2-3 flasks but in difficult levels you can see 4-5 flasks that should be filled exact color of water. In some cases, you need to mix various colors of liquid to get the necessary color and only after that to think how to fill it to the right flask. In some cases, many players just make higher IQ solutions that can't be expected even from developers of this project.  In any case, we hope you will love the game. Let the liquid run, let's have fun!
