It Rocks. Download it.

I can play it all day and it’s so simple. Best game to pick up and play a little and throw it down whenever you need.

True Classic

I’ve downloaded this game onto my last 3 phones because it’s so simple, satisfying, and peaceful. NO ADS!!! No annoying “buy this boost!” pop ups, just a game. You can buy stuff but it’s only mentioned when you first install the game :)

Longtime fan

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

Been playing for years

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

FAQ

What is Atomas?

Atomas is a puzzle game where players combine atoms to create new elements, starting with hydrogen and progressing to more complex ones like Gold and Platinum. The goal is to strategically fuse atoms to achieve high scores without overfilling the game universe.

How do you play Atomas?

You start with hydrogen atoms and use 'plus' atoms to fuse them into helium, then two heliums into lithium, and so on. The key is to build symmetries and trigger chain reactions to create valuable elements and prevent the universe from becoming overfilled, which ends the game.

What are the game modes and features?

The game offers 4 different game modes, 124 different atoms to create, and 12 different lucky charms that can affect gameplay. It also features exciting challenges, score comparison via GameCenter, and social sharing options.

Is Atomas free to play?

Yes, Atomas is free to play. It does include in-app purchases, which may offer advantages or cosmetic items, but the core gameplay and ability to create all atoms are available without spending money.

What is the objective of the game?

The primary objective is to create valuable elements like Gold, Platinum, and Silver by strategically fusing atoms. A secondary objective is to prevent the game universe from becoming overfilled, which leads to a game over. High scores are achieved through efficient fusion and chain reactions.
