royal-checkmate

Royal Checkmate is a polished chess-style duel built for quick Poe play. It uses real chess rules, a cute Three.js board, large aligned tap targets, and synced game state so every legal move, capture, check, and checkmate stays consistent.

What you can do

• Tap to move — select a piece, then tap one of its highlighted legal destinations.
• Play real chess rules — legal moves, captures, checks, draws, stalemates, and checkmates are validated with chess.js.
• Track the battle — the top area shows turn and material score while the bottom area keeps the latest move and restart action close to your thumb.
• Use the compact layout — the board, status, help button, and controls are tuned for 300x500 and 350x509 Poe feed frames.
• Share synced state — the current FEN, move history, scores, and terminal state live in synced-store.

Built on Synced-Store

Royal Checkmate stores the public board state in Poe synced-store and renders the playable board with Three.js.
