Shadow Queen Chess is standard chess with one secret twist: before play begins, each player secretly designates one of their pieces (not the King or Queen) as their Shadow Queen. That piece moves normally — but can also move and capture as a queen at any time.
At the start of the game, click the ⬡ Activate Shadow Queen button, then click any of your pieces (except the King or Queen) to secretly designate it. A purple dot appears on your piece — only you can see it.
Your Shadow Queen stays hidden until one of these occurs:
Upon reveal, the piece permanently converts to a queen on the board.
Standard chess rules apply: checkmate, resignation, timeout, stalemate, or threefold repetition. The Shadow Queen adds bluff, deduction, and surprise — your opponent never knows which piece is secretly a queen.
