Color Stars is one of the Tap Games that you can play on gamesfun.com for free. In this game, you must match the color of a rotating ball to the balls surrounding the planet. This might sound complex but it is easy to pick up - you have three potential ball colors - red, yellow and blue - you use your mouse button to change the color of your orbiting ball. The color of your orbiting ball must match the color of the next ball in orbit and so on.
