Splitting the atom had many consequences for human technology, some of them helpful also potentially dangerous if handled improperly. Fortunately, we’re not dealing with any of that in this game, but we get to see how it works in action. Burst just one of the circles with letters and cause a cascading chain reaction.

  • The dots travel in a straight line. Their movements are based on their placement on the circles.
  • In later levels, you must move some circles to the correct positions to enable chain reactions to clear the level.
  • Play through 30 challenging levels.

What’s This About Splitting Atoms

Using instruments that shoot a subatomic particle moving very fast at the center of an atom (the nucleus), scientists can effectively split it into two atoms. The new atoms formed will be of a different element (pure substance) altogether.

Depending on the element used, you can also use this to make a lot of energy. This is especially true if you used heavy radioactive substances like uranium. Split a few uranium atoms and they cause other atoms to split, creating a chain reaction that goes on and on. Though it does come with a price; the waste created from nuclear power is lethal to humans must be handled with extreme care.
