Blast is a good game of this genre, but now you’re going to play in the open space. Coloured asteroids are coming to the planet. They will certainly fall down on if you do not protect the planet. You need to make colour chains of three or more balls. Then shoot and they disappear. Some asteroid balls contain hidden bonuses that can help you to pass the level. Your goal is to destroy all the asteroids and keep them from the black hole. Remember that you can only destroy colour asteroids with a ball of the same colour. Otherwise it can become a part of a destructive chain.
