Opus Magnum

Catch the falling elements of the alchemical Great Work and turn them into gold. Four stages, three fires, about three minutes.

Move the ring with the mouse or arrow keys. On a phone, drag anywhere on the field. Esc pauses.

How the game works

Alchemists called their work the Opus Magnum, the Great Work: turning raw matter into the philosopher's stone. They followed it through four stages and recognised each by the colour of the matter in the vessel: black, white, yellow, red.

The game follows the same four stages. Your vessel is the Ouroboros, the serpent that eats its own tail. Whatever falls through the ring goes into the work. Gold is counted in grains, and the athanor, the alchemist's furnace, burns on three fires.

  1. I · Blackening

    Nigredo — Calcination

    Everything begins in the dark. Catch any element that falls and keep the dross out of the ring.

    Gather 15 elements

  2. II · Whitening

    Albedo — Separation

    Now the work asks for one thing at a time. Catch only the element the recipe names. Anything else spoils the batch.

    Follow four recipes

  3. III · Yellowing

    Citrinitas — Conjunction

    Opposites must meet. Catch a pair in order: the first half waits in the ring until its partner comes. Watch the Green Lion: it eats a waiting Sun.

    Join three pairs, then catch the Key

  4. IV · Reddening

    Rubedo — Multiplication

    The last fire. Everything falls at once. The Pelican doubles your gold, the Phoenix relights a fire. When the time runs out, catch the Philosopher's Egg.

    Hold out 30 seconds, then catch the Egg
