Atomas

Atomas is an incremental puzzle game that starts with a universe containing only hydrogen atoms. By using energy-rich plus atoms, you can fuse two hydrogen atoms into helium, then two helium atoms into lithium, and continue up the periodic table. Your main goal is to create valuable elements like gold, platinum, and silver.

Be careful: if your universe becomes overfilled with too many atoms, it will trigger a big crunch and end the game. One way to prevent this is to build long symmetries among your atoms and set off big chain reactions. From time to time, minus atoms appear; use them to absorb and replace atoms in your universe or sacrifice them for a plus atom.

Creating new elements such as oxygen or copper unlocks lucky charms that affect the game in various ways and let you adjust it to your strategy. The game is easy to learn, but reaching the top requires a good strategy to keep your atoms organized.

Atomas offers four different game modes, simple but addicting mechanics, 124 different atoms to create, 12 lucky charms, Google Play Games leaderboards and achievements, score sharing on Twitter and Facebook, and a quick tutorial. The developer's high score is 66,543. Can you do better?
