The Games

Seven games have collapsed into reality. The rest are still in superposition.

● Live nowVersus

Quantum Tic-Tac-Toe

Place one mark in two squares at once. Entangle the board, force a collapse, and win the line that measurement leaves behind. Play a friend or the machine.

● Live nowVersus

QPong

Pong, but the ball is a qubit — and you're the physicist. Hit it off-center to spin it into superposition; the center line measures it and it veers — |0⟩ left, |1⟩ right. You set the odds. First to 7, versus a friend or the machine.

● Live nowVersus

QTwist

Pong, but the midcourt is a quantum field — and you're only the observer. A band rewrites the ball's law every few seconds: it delocalizes, tunnels, splits into twins, or forgets its momentum. Read it and defend. First to 7, versus a friend or the machine.

● Live nowArcade

Zeno Man

A quantum-Zeno maze chase. Your gaze freezes any ghost caught in it — but you can only look one way, and the ones you're not watching hunt you down. Eat every photon before they reach you. Play solo.

● Live nowVersus

Quantum Connect Four

Drop one spooky disc into two columns at once. Entangle the columns, close a loop to force the collapse, then stack four real discs in a row. Versus a friend or the machine.

● Live nowLab

QShift

Steer a photon by interference. Rotate the phase shifters so amplitudes cancel, drive every mine detector dark, and thread the safe port. Five interferometers to tune.

● Live nowLab

Quantum Escape Room

Assemble real quantum circuits — H, X, Y, Z, S, T and CNOT gates — to match each locked target state and spring the lock. Six rooms of gates between you and the exit.

In superposition

Entangled Minesweeper

Mines exist in two cells until you look. Every click is a measurement.

In superposition

Qubit Chess

Pieces move as probability clouds. A capture collapses the whole board.

In superposition

Superposition 2048

Tiles hold two values at once. Merge the wavefunction, not the number.

In superposition

Schrödinger's Solitaire

Face-down cards are both red and black — right up until you flip them.

In superposition

Wavefunction Reversi

Flip discs into entangled pairs and choose which reality settles the grid.

New to quantum? Good.

You don't need physics to play — but you'll pick up the real ideas by winning.

CONCEPT 01

Superposition

A quantum thing can be in two states at once. In the game, your mark lives in two squares until something forces a choice.

See it in Tic-Tac-Toe →
CONCEPT 02

Entanglement

Link two things and measuring one instantly settles the other. Those glowing threads between the columns? That's entanglement doing the work.

See it in Connect Four →
CONCEPT 03

Collapse

Look, and the maybe becomes a definitely. A loop on the board triggers a measurement — every mark snaps into one real square.
