Atomic theory is difficult. Fortunately, this game does not require complicated theory.
Atoms are currently floating in an unstable state (white) in the maze.
Here you have to move the tunable atom (orange) to make contact with the prepared atom (yellow).
Atom that has completed its mission finds stability and emits its original color,
The atom that is touched becomes in control.
One of the remaining atoms is ready again, and a new unstable atom appears in the middle of the maze.
Of course, no complicated theory is needed in this game.
The walls of the maze are movable, and no one knows what will happen if they come in contact with an unstable electron. (Maybe a new big bag??)
Now, time to go on a journey to stabilize the atoms in the maze.
