Atomicity is a very addicting transport puzzle game.

The objective is to assemble the molecules shown using the atoms on the board. Sounds simple, huh? The part where this seemingly easy task gets more difficult, is that once an atom starts moving in one direction, it will continue moving until it hits another atom, or a wall.


- 48 Levels of varying difficulty
- 16 Bonus Levels
- Auto Save (if you stop in the middle of a game, you can pick right back up where you left off)
- Sound Enable/Disable
- Statistics
- Undo
- Pause
- Board Reset (if you get stuck and want to start over)


Reassemble the molecule shown in the example window (pay attention to the connectors between the atoms)

How to Play:

- Tap on an atom on the playing surface to select it. It will display the possible directions it can move using yellow arrows.
- Use the Directional arrows on the right of the screen (under the example window) to move an atom (only the valid direction will "light up").
- An atom can only move in one direction at a time.
- Atoms will continue moving in the chosen direction until they hit another atom or a wall.
- The next set of 6 levels (plus 2 bonus levels) are unlocked when all the previous levels (not including the bonus levels) are completed.

- You can undo your latest moves by clicking on the Undo button
- You can reset the move count, board, and timer to their initial values by clicking on the Reset button
- Pay attention to the connectors between atoms

Great Game!


This game looks simple enough, but once you start it is like you cannot put it down. The first couple of levels give you a taste of what is to come. I think that I have spent 15 hours playing and replaying this game, trying to find the quickest way to beat a level. This is a really great game and is definately worth the 3 bucks. You will not be disappointed.

BTW 15 moves on the first level in 11 seconds, try to beat it!!!



I have had my ipod for several years and I play games on it daily. But I have
not run across any other game that can even come close to this game. It really does give your brain a good workout. Love this app make more levels or other games like it. I will replay this app many times I'm sure!!!!
