The atoms are spreading and we need to clear them fast in this unique strategy and puzzle game. Can you destroy all the atoms by the use of a single atom too? Step up to finish the challenge here in Meltdown! You will be given a board full of hexagons and some of them are filled with green atoms. You must shoot them with particles in order to expand them. They will explode if they have reached their maximum size and their particles will spread out shooting nearby atoms as well. Try to limit your shots as much as possible to continue playing and for more points.
