A chain of glass marbles rolls out of the cave along the groove towards the hole. Aim your slingshot with the mouse (or ← →) and click (or Space) to shoot a marble into the chain. Three or more of one colour in a row pop. When a gap closes between two marbles of the same colour, the front part is pulled back and can pop again — chain reactions score double, triple… Right-click or X swaps your marble with the next one. Special marbles: 🐌 slows the chain, ⏪ rolls it back, 💣 blows up its neighbours, 🎯 gives a laser sight. Clear every marble to finish the level; if the chain reaches the hole you lose a heart.
More colours, a faster chain, longer rows. Play Marble Chain: Storm free in your browser — no download, no sign-up, on phone or computer.
