The Classic Game of Strategy
Choose a piece to promote to:
Capture the opponent's king by delivering checkmate.
White moves first, then players alternate turns.
Click or tap one of your pieces to select it.
Click or tap a highlighted legal square to move.
Move onto an opponent's piece to capture it.
Your king is under attack and must be protected immediately.
The king is in check with no legal escape. Game ends.
King moves 2 squares toward a rook; rook jumps to other side. Neither piece may have moved, no squares in between attacked.
A pawn that just moved 2 squares can be captured by an adjacent enemy pawn as if it moved only 1 square.
A pawn reaching the opposite end can become a Queen, Rook, Bishop, or Knight.
Stalemate (no legal moves, not in check), insufficient material, threefold repetition, or 50-move rule.
