How to Play Shogi

Overview

This is full-board Shogi: you (Sente) vs CPU (Gote) on a 9x9 board, with 16 selectable CPU levels.

Core Rules

• You win by capturing the opponent king or delivering checkmate.
• Captured pieces become your hand pieces and can be dropped later.
• Promotable pieces may promote when moving in/out/within the promotion zone.
• Pawn/Lance/Knight are auto-promoted if they would have no legal move otherwise.
• Two unpromoted pawns on the same file are not allowed.
• Pawn-drop mate is prohibited.

Controls

• Click your board piece to view legal destinations.
• Click a hand piece button to view legal drop squares.
• If promotion is optional, a confirmation dialog appears at move time.
• Change level or press "New Game" to restart the match.

Note
