quantum-tic-tac-toe

Quantum Tic-Tac-Toe is a compact synced board game where each turn places one paired ghost mark across two open cells. Active pairs can collapse into a classic 3x3 board, and a resolved three-in-a-row ends the round.

The app is built for small Poe frames with a mobile-first Three.js board, direct cell taps, animated pair links, deterministic collapse, and a one-tap terminal drill.

What you can do

• Pair two cells: Tap one open square, then another, to place a linked ghost X or O.
• Collapse the board: Turn active ghosts into classic marks and check for a terminal line.
• Practice the drill: Load a deterministic collapse position that resolves into an X win.
• Restart quickly: Use the bottom action bar to collapse, load the drill, or start a new round.
• Play in a Poe frame: Synced-store keeps the board state consistent across the app instance.

Development
