Marble, obsidian and brass in honest 3D. Orbit with the right mouse button or a single finger, zoom with the wheel or a pinch. Light and shadow are computed live, and the quality adjusts itself to keep the frame rate up.
Quick play finds you a living opponent. Want a specific one? Create a room and send a friend the code. Nobody around? A bot on three levels: beginner, amateur, master. The last one does not forgive.
Time control with an increment per move: when the flag falls, the game is over. Live games count towards your rating and the leaderboard. Bot games are practice only and never touch your stats.
When the game ends, the board explains why the king had nowhere to go: attacked squares are crossed out, squares blocked by his own pieces are hatched, and a beam runs from every piece that holds a square. Not just “mate”, but who delivered it.
Mechanics
Castling, en passant, promotion with a choice of piece, draws by threefold repetition, the fifty-move rule and insufficient material. The engine knows everything an arbiter knows.
An opponent within seconds. Or your own room: the code goes to a friend, everyone else joins as a spectator and watches the game live.
Beginner, amateur, master. It thinks in a separate thread while you spin the camera. Bot games never touch your rating or your stats.
After mate, the board shows who holds every square around the king: crosses, hatching, beams. A win comes with an explanation, a loss with a lesson.
Watch other people's games, climb the leaderboard, argue in the room chat or the global one. Any game can be copied as PGN.
