- There are unique atoms in each level in the game.
- You need to get at least two stars in a level in order to play next level.
- Three stars can be earned if a level is finished in a given time, if the Bad Electron is shot more than 5 times in a row, and if nucleus of the atom is not shot with the laser at all.
- You have to shoot the Bad Electron with the laser until it blows away so that the atom is stabilized.
- Orbital shapes and numbers differ in each level.
- Bad Electron passes between orbitals based on its energy.
- You will earn free rewards at the end of each level if you finish the level in a given time and if you shoot the Bad Electron more than 5 times in a row.
- You can use those free game rewards to get bonuses which make easy to pass a level.
- These rewards include nucleus protection which constructs a shield around the nucleus so that one of the stars is guaranteed.
- The other free game reward freezes the time which makes another star available.
- You can always play a previously achieved level freely.
- Enjoy Bad Electron!
