Atoms

Stellar fusion merge puzzle

Free · Designed for iPad. Not verified for macOS.

Slide. Fuse. Go supernova. Climb the real fusion chain from helium to iron - then forge gold from the shockwave. Atoms is a merge puzzle built on the real physics of the stars. Swipe to slide every atom on the board. Matching atoms fuse into the next element, exactly like stellar nucleosynthesis: helium to carbon, carbon to oxygen, all the way up the fusion ladder to iron. But iron doesn't fuse. Iron explodes. Slam two iron atoms together and you trigger a supernova - a shockwave that wipes the whole 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: Fe + Fe detonates, wipes the whole board, and forges Au - only gold survives - Two looks: sleek glass design, or flip the 64-BIT switch for retro pixels - Dark and light themes - Four difficulty levels, from chill 6x6 ZEN to brutal 4x4 HARD - Per-level persistent high scores - One-handed play, no timers, no pressure - just you and the periodic table Easy to learn, deep enough to master. How far up the fusion chain can you climb?

Big-screen polish: the board now keeps its proportions on iPad - tiles and spacing scale together. Small fixes and tune-ups.
