Reactor

The goal of the game is to direct each atom to its color-coded receptacle. There are 15 atoms and receptacles of each color per level. Change the direction of an atom by dragging an arrow from the upper-left part of the screen into the path of an atom of the same color. The atom will then move in the direction of the arrow you placed in its path. Grey arrows change the direction of all atoms. To change the direction of an arrow click on one of the green directional arrows that appear.
