About Chess3dastra
Chess3dastra is full-rules chess against a computer opponent that runs locally in your browser. Castling, en passant, promotion and draws are all in, and you choose one of three difficulty levels before you start.
According to the repository, it was built in the GitHub Copilot app with GPT-6 Astra from four prompts, including a review pass by a second agent. It ships as a single static HTML file with unit and browser tests, and the computer's search runs in a Web Worker so the interface stays responsive.
You move by clicking, with the keyboard or by typing algebraic notation, with undo, a move history and a captures list at hand. The board switches between 3D, with hand-made pieces and an orbiting camera, and a flat 2D view. That choice survives a reload, and so does a game in progress.
