Are you ready for a fun and challenging puzzler? Then Flow Free is the game you are looking for! Flow Free tests your ability to correctly figure out how to connect the dots with pipes, all without breaking other pipes or leaving any squares on the game board unused. It starts off simple enough, but soon grows much more challenging. Do you have what it takes to win or will you give up in frustration?.
Color Alchemy is another cool app like this. It has literally 100's of levels and different tools to mix and match the color pipes, making it harder and more addictive. https://play.google.com/store/apps/details?id=com.elementmodulus.coloralchemy
