Atoms: Stellar Fusion

Atoms is a stellar fusion merge puzzle built on the real physics and chemistry of the stars. Swipe to slide every atom on the board. Matching atoms fuse into the next element, following stellar nucleosynthesis: helium to carbon, carbon to oxygen, all the way up the periodic table to iron. But iron doesn't fuse. Iron explodes. Slam two iron atoms together and trigger a supernova — a shockwave that wipes the board and forges pure gold. Only gold survives. Bank pairs of gold for massive points and keep the chain reaction going as long as you can. FEATURES • Real fusion chain: He → C → O → Ne → Mg → Si → S → Ar → Ca → Ti → Cr → Fe • Supernovae: iron + iron detonates, wipes the board and forges gold • Two looks: sleek glass design or flip the 64-BIT switch for retro pixels • Dark and light themes • Four difficulty levels, from chill 6×6 ZEN to brutal 4×4 HARD • Per-level persistent high scores • One-handed play with no timers and no pressure • A complete premium game with no advertising, subscriptions or in-app purchases • Play offline with no account required Easy to learn, deep enough to master. How far up the stellar fusion chain can you climb?
