merge matching atoms and climb the real stellar fusion chain — helium all the way to iron, then forge gold from supernovae.
swipe (or arrow keys / WASD) to slide every atom on the board. each move spawns a new atom.
two matching atoms fuse into the next element:
He+He=C · C+C=O · O+O=Ne · Ne+Ne=Mg · Mg+Mg=Si · Si+Si=S · S+S=Ar · Ar+Ar=Ca · Ca+Ca=Ti · Ti+Ti=Cr · Cr+Cr=Fe
each fusion pays the new atom's mass in points.
Fe+Fe won't fuse — it explodes! +1000, the shockwave wipes the whole board (half each atom's mass in points) and forges Au. only gold survives.
Au+Au = bank +5000 and both clear off the board.
sets the board size and spawn odds:
ZEN 6×6 · He 50% / C 50%
EASY 5×5 · He 65% / C 35%
NORM 4×4 · He 80% / C 20%
HARD 4×4 · He 95% / C 5%
lines mark pairs that can fuse. the ladder at the bottom tracks your progress — tap any chip for details.
board full with no merges left = game over.
