The Chess Club’s Lucky Rook
A wooden rook used as the chess club’s good-luck token is hidden beneath one of four boards before the final round. Four players each sit at a different board, and a handwritten seating note identifies the token’s location.
Your task
Under which board is the lucky rook?
- 1
The token is not beneath Mira’s or Joel’s board.
- 2
Mira plays at Board 1 and Joel at Board 3.
- 3
Board 2 was lifted during setup and had nothing beneath it.
- 4
Exactly one board hides the token.
Solution revealed
Solution
The answer: Board 4
Mira’s Board 1 and Joel’s Board 3 cannot hide the rook. Board 2 was checked and found empty. Since exactly one board contains the token, the only remaining possibility is Board 4.
