Apps / Tamerlane Board
Timur's 14th-century chess with giraffes, war engines and citadels.
Play Tamerlane chess, the medieval Timur variant on an 11 by 10 board with citadels, against a computer opponent, or invent your own pieces. Each piece is described in one short line of movement notation, so you can design a new one, watch where it can reach around blockers, get an estimated value and drop it into Timur or classic chess. Six computer-versus-computer games test whether your piece unbalances the game, and a share link sends it to anyone. History cards explain each historical piece.
Some rules are simplified, such as no king swap, and the classic chess mode has no castling or en passant.
