Japanese Chess

Shogi, also known as Japanese chess, is a two-player strategy board game that has been played in Japan for centuries. Played on a 9x9 board with 40 pieces total, Shogi stands apart from Western chess through its revolutionary "drop rule" — captured pieces switch allegiance and can be redeployed onto the board as your own. This single mechanic transforms every game into a dynamic battlefield where material advantage means something entirely different. Professional Shogi players in Japan are celebrities — the top player Fujii Sota became the youngest ever to hold all eight major titles at age 20.
Each player starts with 20 pieces: 1 King, 1 Rook, 1 Bishop, 2 Gold Generals, 2 Silver Generals, 2 Knights, 2 Lances, and 9 Pawns. On your turn, you either move a piece on the board or drop a captured piece from your hand onto an empty square. When pieces enter the opponent's last three ranks, most can promote to stronger versions. The Rook becomes a Dragon King and the Bishop becomes a Dragon Horse — both gaining additional movement. The objective is to checkmate the opponent's King, just like in chess, but with the added complexity of drops making the endgame wildly unpredictable.
The biggest difference is the drop rule: captured pieces switch sides and can be placed back on the board as your own. This means material is never truly lost, creating incredibly deep strategy. Shogi also features piece promotion in the last three ranks, and different piece movements from Western chess.
When a piece reaches the last three ranks (the opponent's territory), it can be promoted. Promoted pieces gain enhanced movement abilities. Rooks become Dragon Kings (adding diagonal movement), Bishops become Dragon Horses (adding orthogonal movement), and Silver, Knight, Lance, and Pawn all promote to Gold General movement.
When you capture an opponent's piece, it goes into your "hand." On any future turn, instead of moving a piece on the board, you can place (drop) a captured piece onto any empty square as your own piece. Dropped pieces return to their unpromoted state. There are restrictions: pawns cannot be dropped on a file that already has your unpromoted pawn, and pieces cannot be dropped where they would have no legal moves.
