One drop. Then everything goes.
Match a colour and the orbs above fall into place. A new match starts the next link in the chain.

PARTICLE-PHYSICS PUZZLE · ANDROID
QUARK
FORGE.
A little colour.
A lot of chaos.
Drop pairs of coloured orbs. Match three or more, break the crates and keep a chain reaction going. Then things get wonderfully strange.
Antimatter blasts, gluon strings and plasma fever turn ideas from particle physics into puzzle mechanics. Curious where they come from? Optional “Real physics” cards explain the connection.

MECHANIC DEMONSTRATIONS
It starts with a match.
A whole colour. Gone.
Match five to forge a gluon. This wildcard joins a group and sweeps every orb of that colour away.
Now turn up the heat.
Keep the chains coming to fill the plasma meter. Your next drops go white-hot and pop everything they touch.
FOR CURIOUS MINDS
Inspired by
particle physics.
Quarks are tiny building blocks of matter, found inside protons and neutrons at the centre of atoms. Their strange world gives this puzzle its wildest ideas.
The game's optional “Real physics” cards connect the mechanics to the science behind them. Here are three of those connections.
Explore the physics at CERN ↗Antimatter Opposites annihilate
Matter and its antimatter counterpart annihilate when they meet. In Quark Forge, that becomes an explosive way to clear orbs.
Gluon strings A powerful connection
Gluons carry the strong force that binds quarks. The game turns that connection into glowing strings: pop one end and the other goes too.
The Higgs field A little more mass
Elementary particles acquire mass through interactions with the Higgs field. In the puzzle, glowing fields catch and hold orbs, changing where you can place a pair.
