This is not just any puzzle game. This is a quantum puzzle game! You can just play it for fun, or you can use it to conduct scientific research in the field of quantum error correction. These are the puzzles that need to be solved to keep quantum computers free of errors. We need to work out the best way to do it. By becoming a master at this game, you could help build a real-life quantum computer. Check out our website for more details on the science behind the game. This app was developed by Dr James Wootton, a quantum error correction researcher at the University of Basel. It is supported by the NCCR QSIT.
Quantum Fusion
Read full descriptionHide 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.

Verdict
The clearest difference is in-app purchases: Decodoku at none against Quantum Fusion's 1. Decodoku also leads on device support (3 vs 1) and iOS requirement (8.0 vs 16.0). On price and ads there is nothing between them.
