Chess

Full standard chess, done properly in 3D — no shortcuts on the rules.

Features

• Complete rule set — castling (both sides), en passant, pawn promotion with a real piece choice, check/checkmate/stalemate detection, pinned-piece legality
• Real AI opponent — minimax search with alpha-beta pruning across 3 difficulty levels, tactically aware (it finds mate-in-1s and takes free material without prompting)
• 2-player local — skip the AI, play someone next to you
• Distinct 3D pieces — every piece type has its own genuinely different silhouette, not just a scaled pawn
• Undo if you misclick

Runs entirely in your browser — no install, no plugins. Windows, Mac, Linux, all fine.

Controls: Click a piece to select it, click a highlighted square to move.
