About

Quantum Fusion

Features
Read full description

Fuse the universe, one particle at a time. Quantum Fusion is a physics-themed twist on the classic merge puzzle. Slide to combine subatomic particles and cosmic objects — from humble Quarks up through Protons, Atoms, Molecules, and Stars, all the way to a Black Hole. Every tile is drawn in real time by a single custom shader: glowing orbs, orbiting electrons, comet tails, pulsar beams, and an event-horizon photon ring. But this is more than 2048 in space. Original mechanics change how you play: • Quantum Superposition — tiles exist in two states at once until observed • Electron Capture — Protons quietly evolve by absorbing electrons • Quantum Tunneling — particles fuse straight through barriers Simple to pick up, deep to master. Chase the leaderboard, plan your merges, and see how far up the cosmic ladder you can climb.
