Atomas

Originator Max Gittel
Primary Metric 3,390
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?

I’ve been playing this game for 10 years relatively consistently. It remains a favorite for its simplicity, design, and replayability.

I have been playing atomas for at least ten years at this point. I love this game. It doesn’t have any ads and doesn’t force any spendings on you to win. Also the gameplay is fun. Has different game modes, but i just play the basic one usually.
Great game, great app, i appreciate the developer for not making this game a money cow

The game forces you so that right after your last move you get a plus. It makes you pay for fricking antimatters when they could just give you free antimatters for an ad or something. I do not recommend this game for beginners.

This is one of my favorite games, and I hope more people will get to play it, but I have one suggestion for you. PLEASE DECREASE THE AMOUNT OF ATOMS YOU HAVE TO GET TO UNLOCK ZEN MODE.

How long ago did this app come out? It has to be over a decade ago now, right? Well anyway, I play this game every day and I love that it doesn't have ads, it's simple but difficult. It's calming because you go at your own pace. Easily my favorite app. Please never change!

dude this is amazing, just got this and its amazing, keep adding more

If you’re going to have a game with real names of elements you could at least use semi-accurate chemistry, but then to not even use accurate 1st grade math, it’s embarrassing, offensive. Two Heliums (2x2) make a Beryllium (4), not a Lithium (3). Stellar nucleosynthesis is just an alpha and beta decay, two options for changes in atomic number (+/- 4 or 1). It would be really easy for anyone with a 6th grade education with a very short tutorial. Too bad.

This game is my favorite but there are SO MANY BUGS!!! One I found is that when the game ends, there is a share button. When you click the share button, it crashes the app.

Eh, pretty fun

Smooth, easy concept, gets challenging, doesn’t plague you with advertisements

The app helps you memorize the elements while playing a fun atom merging game.

I found a glitch with the ( - ) power, I’m not sure exactly what caused it, but I used it in a hydrogen, placed it, pressed undo (time machine) and it undid two moves while replacing the original hydrogen with nitrogen, and gave me an extra hydrogen to place.

The difficulty of the game progresses nicely with the length of the gameplay.

I just understand the idea or goal of the game is the tutorial isn’t enough. I know trial and error is a thing but it’s a game, no? It’s kind of boring.

I love this game, but it had issues. The randomness means I could be getting mountains of +s I don’t need. Or I lack them when they are needed. Also, I wish there were more power ups.

Game is great played it before loved it it’s simple it takes skill and luck but could you update this game maybe make the graphics better and such or even add different music.love the game just sad to see it hasn’t updated in years.

It’s my first time playing! I got to Nobelium! Where are the game modes?
Muffmuncher97 • Mar 1, 2024 ★ 3
This game is really cool but it has a major flaw, I think. As you’re playing the game will give subtle hints as to what you should do next, where the atom best fits in. But if you’ve already started your own chain and you don’t follow the hints then it seems almost like the game punishes you by denying you positives until you fill out the game area. Obviously I can’t prove this so it’s entirely unfounded but it’s just how I feel.
