Atomas is a fascinating puzzle game, which you can learn in seconds but will entertain you for weeks. The perfect game for your spare time!

Your little universe starts with hydrogen atoms only but with the help of the energy rich plus atoms you are able to fusion two hydrogen atoms into one helium atom, 2 helium atoms into one lithium atom and so on. Your primary goal is to create the valuable elements like Gold, Platinum and Silver.

But watch out, if your universe is overfilled with too many atoms it will cause a big crunch and the game is over.
One way to prevent this is to build up long symmetries in your atoms and start big chain reactions.

From time to time minus atoms appear, use them for absorbing and replacing atoms within your universe or sacrifice them for a plus atom.

You see Atomas is not hard to play, but if you want to get to the top you'll need a good strategy, which keeps your atoms organized.

By creating new elements like oxygen or copper you unlock lucky charms, which effect the game in various ways and adjust it to your strategy.

What Atomas offers you:

- 4 different game modes
- simple but addicting game mechanics
- 124 different atoms to create
- 12 different lucky charms
- exciting challenges
- compare your scores with friends via GameCenter
- share your score on twitter and Facebook
- quick tutorial

The developers high score is 66 534. Can you do better?

Very fun, but winning is based on luck

I’ve been playing this game for years, I’ve gotten nearly double the “devs highscore,” and while it’s a very entertaining game fun to play in those short moments when I’m on a bus or waiting in line, I’m convinced it isn’t beatable by skill alone. There is a not insignificant factor of luck, and as you get closer to the end game it’s programmed to make your luck worse by giving you numbers that are further and further apart from one another and reducing the chance of + and - it seems making it unbeatable. In the last game I lost I had 1 piece left on the board then got enough numbered pieces (without any + or -) in a row to lose the game, that’s what really set me on the path of changing my review to this one. Being luck based it’s theoretically possible to win by getting lucky but I don’t like that. For a game like this I usually rate 1/5, 3/5 is the highest rating I’ll give for an unbeatable or win by luck game.

Thank you so much!

I love this game so much! Not only is it fun, but it is very helpful! I started playing this game early last year and wasn’t in Chemistry. Now I am in Chemistry, and we actually had a quiz on naming the first 20 elements on the periodic table. I forgot about it and didn’t study, but what helped me to ace it was this game. It helped me to remember the elements and the order of them. The next quiz we have will be the first 50 elements, and believe me, I WILL be using this game to study!☝️

For the Geneva mode, if you use the green thing twice in a row on an atom, it stays plus until you fuse two atoms using it. Please fix the Geneva mode.
If you use the undo button, it undos the move. But if you use it again, nothing happens.
Another bug, you can get to like protactinium or higher on tutorial (just click outside the check mark when step done) and for step 6 you can absorb the atom then spam in the middle of the center and the outside, then the check mark will not appear.
