Empyr / Minigames

Two seats,
one clock.

A board for two, with room for spectators. Every rule is enforced on the server — castling, en passant, promotion, mate, stalemate and every draw condition. The clock lives there too, so a flag is never up for debate.

How it works

How it works

What is actually in there

What is actually in there

A hand-written rules engine, no libraries.

Castling and en passant

Every condition: no castling through check, rights that expire, and a capture right that lapses after one move.

Promotion you choose

Queen, rook, bishop or knight — never silently queened.

Automatic draws

Stalemate, dead material, fivefold repetition and seventy-five moves end the game on their own.

Claims

Threefold repetition and the fifty-move rule are yours to claim, exactly as in a tournament.

Flagging with no material

Run out of time against a side that cannot mate and it is a draw, not a loss.

Notation and PGN

Full algebraic notation with disambiguation, plus a PGN of the finished game to copy.
