Games where quantum mechanics is the trick

Nothing to install — these games run in your browser. One of them brews real coffee, wherever a Qoffee-Maker is set up.

🧩

Entangible ↗

Build a quantum circuit with your hands — gate tiles on a table, live results on the screen.

Lay gate tiles on a board and watch the circuit come alive: a camera recognizes the layout, the big screen shows the circuit and its measurement results as you build. Made for booths, classrooms and kitchen tables — print the kit, or use the on-screen boards. Its Quantina mode, the successor of the Qoffee-Maker, lets the circuit’s probabilities pick a drink.

  • A camera reads printed or 3D-printed gate tiles and simulates the circuit live
  • Runs in the browser on a laptop, tablet or phone — no install
  • Quantum Golf, Quantum Runner and the Quantina drinks menu built in

Qoffee-Maker ↗

Order your coffee with a quantum circuit.

Build a quantum circuit whose measurement outcome decides which coffee the machine brews. Put the qubits in superposition and let physics choose your drink — a caffeinated way to learn what a measurement is.

  • Conference favorite — the circuit's measurement picks your drink
  • Eight drinks, three qubits, one superposition

Quantum Runner ↗

Steer the runner with quantum gates — an H gate puts you in both lanes at once.

A quantum-circuit puzzle game where the circuit is the controller: the state of your qubit decides which lane the runner takes, superposition lets you collect coins in both, and the simulation results are the game logic.

The notebook games

Each game is an interactive Jupyter notebook — one click, no account. It opens a free session on mybinder.org (via QuBins), so starting it can take a few minutes. Games marked ▶ also play right on their page. Play first, then pull back the curtain and see the circuit.
