StockPuzzle based on the rules of TabletopGame/{{chess}}. A grid representing a subsection of a chessboard is shown, and the puzzle solver must place a certain number of queens on it so that none of them threatens the others: that is, none can share a rank, file, or diagonal. The standard puzzle is "Place ''N'' queens on an ''N''x''N'' board," with a value of N between four and the standard eight of a full board. The puzzle can't be solved for N = 2 or 3.

SubTrope of GridPuzzle, the general trope for puzzles solved by arranging the elements of a grid. Compare MagicSquarePuzzle (a square array of integers that sum the same in each row, column, and main diagonal).

[[folder: Live-Action TV ]]

* ''Series/TheCrystalMaze'': In the tenth episode of the fourth series, the team of the week is tasked with solving one of these puzzles in the Medieval Zone.

* ''VideoGame/AdventureEscape'': ''Murder Inn'' uses TabletopGame/{{checker|s}} pieces to represent the eight queens. The puzzle needs to be solved [[SolveTheSoupCans in order to open a drawer.]]
* ''VideoGame/{{Core}}'': An N=6 variant appears in the ''Tower Core'' flash game, inside one of the three towers.

* ''VideoGame/ProfessorLaytonAndTheCuriousVillage'': The puzzles given by the chess player in the tavern are N=4 and N=5, and one of the bonus puzzles is a full 8. The hints for the bonus puzzle tell you to not bother buying more hints, as you should know how to do it by that point.
* ''VideoGame/{{Safecracker}}'': The N=6 version appears on one of the safes in the attic. Slightly easier than most examples because every square follows a pattern, as your character is quick to point out.
* ''VideoGame/SplinterCellDoubleAgent'' has a 3D version of this. GenreShift, anyone?
* ''VideoGame/TheWhisperedWorld'': You have to solve this puzzle in the second chapter.
