Domineering Manual

Goal: leave the AI with no legal domino placement.

• Each turn adds one new domino to the board; already placed dominoes never move again.
• A legal move is placing a domino on two empty orthogonally adjacent squares in your required orientation.
• You place vertical dominoes.
• The AI places horizontal dominoes.
• The yellow outline marks the most recently placed domino.
• If a player cannot move, that player loses.
