Vulcanicoin

How it plays

VULCANICOIN is a portrait one-finger arcade game set on the slope of an erupting volcano. A polished gold coin with a volcano crest rolls down through rows of black basalt gates, and a glowing lava twin follows the very same path a moment later.

Drag anywhere on the screen to steer the coin left and right. Each gate has one gap, and the gap keeps swinging like a pendulum. By the time the lava twin reaches the same gate, the gap has already moved — so the trick is to pass on the side the gap is swinging toward, where both of them fit.

Every level gives you a set number of gates and a score goal. A clean pass by the coin scores a point, a clean pass by its twin scores another, and a clean pair adds a bonus. Chain four clean pairs and the whole slope catches fire: for eight seconds every point counts double. Scrape a slab and the fire goes out — three scrapes and the coin cools down.
