The Arcade

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

X₁ · O₂

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.

|0⟩ ⇄ |1⟩

QPong

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

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.

CONCEPT 02

Entanglement

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

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.
