XOXO Quantum Tic-Tac-Toe

A 3×3×3 grid. Each player gets two moves per round to place superposed marks.

How to play

• On your turn, place two tentative marks (superposition) on different cells.
• After each round (two X moves and two O moves), the state collapses: one definitive X and one definitive O remain.
• Continue until the board resolves; three in a row wins!
