An offline 3D chess game by Quantum Billing LLC. Play against Stockfish in the browser, download native builds, or let an LLM play through the built-in chess agent API.
Select one of your pieces, choose a highlighted legal move, and play against Stockfish as Black.
Use mouse, touch, zoom buttons, wheel, or pinch gestures to inspect the board. Flip the view from the controls panel.
Moves animate, the move list scrolls, sounds can be toggled, and check or checkmate highlights the king square.
The pieces are a professionally sculpted Staunton set, with a carved horse-head knight, a slit bishop mitre, a crenellated rook, and a cross-topped king. The default is a glossy ebony and boxwood tournament set on a maple and mahogany board; use the Pieces button to switch to satin wood, the model's own marble finish, or classic white and black. The set is Chess Set by Riley Queen on Poly Haven, released under CC0.
The live game exposes window.quantumChessAgent, so a model-driven browser harness can observe board state, inspect legal moves, and submit chess moves.
const agent = window.quantumChessAgent;
agent.observe();
agent.act({ type: 'move', from: 'e2', to: 'e4' });
agent.act({ type: 'san', move: 'Nf3' });
agent.reset();
