Use your manipulators to move the particles into the reactor! In this challenging strategy game you need to use your mouse (or the arrow keys) to catch hold of the particles and move them into the reactor. You will be using the barriers and windows to lengthen and shorten the beam because each particle will need to be handled in a different way. Some need to be dropped into reactors that match the particle color, others will need to be moved different distances than the previous particles. Also, make sure to stay on the track provided or your turn is over!
