Clockwork Chess
by Maxi · v1.0
Blitz chess with a real clock: a tuned alpha-beta engine at three strengths, pass-and-play, and live online games over the platform relay. Full rules — castling, en passant, promotion, threefold, fifty-move — with hand-drawn vector pieces and a proper flag-fall.
How to play
Click or tap a piece, then click or tap its destination square (dragging works too). Promotion opens a piece picker; flip, sound, resign, draw and rematch are buttons.
