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.
New in v1.3
The way out now sits in the toolbar next to flip, sound and new game, with a fullscreen toggle beside it on desktop, instead of the platform's pill floating over the board. It stays above the menu card so you can leave from anywhere, and the whole toolbar grows to a proper thumb size on phones.
