Pac-Man as a quantum particle. Split into mirrored copies, phase-flip ghosts into edible |−⟩ states, and survive measurement on a coin flip.
Tetris with superposed pieces that collapse on contact. Flip pieces into antimatter that annihilates blocks, and clear entangled pairs in one go.
superpositionannihilationentanglementmeasurement PLAY ▸ |MINEQUEEPER⟩Minesweeper where numbers are expectation values. A half-mine is in superposition, an anti-mine counts −1, and measuring a cell turns guessing back into deduction.
superpositionnegative phaseentanglementmeasurement PLAY ▸ |BREAQUOT⟩Breakout where the ball is a wave packet. Split it on beam splitters, flip its phase, make branches interfere, and catch whichever branch the paddle measures as real.

superpositionentanglementphase flipinterference PLAY ▸ |LIGHTS QOUT⟩A one-player logic puzzle. Every light is a qubit. X presses can't touch |±⟩ and Z presses can't touch |0⟩/|1⟩, so each board is two puzzles connected by a few precious Hadamards.
A logic puzzle that starts as a classical 0/1 Binairo and grows into the whole Bloch sphere. Balance every row on every axis, and read the clues: ○ identical, ● opposite, ◐ unbiased, the overlap no classical bit can have.
2048 where every tile has a phase. Equal tiles with the same phase merge, opposite phases annihilate, Z tiles flip phases and H tiles split a tile into |v⟩ and −|v⟩. Grow, or cancel?
Battleship with the Elitzur–Vaidman bomb tester. Zeno probes find ships without touching them, and more steps make them quieter. A photon the ship absorbs gives you away and draws extra fire.
