You don’t have to be a chess player, or even know the rules of chess, to have a good time with today’s puzzle. All you need to know is that the queen is the most powerful chess piece – she can move as far as she likes in any direction: forward and back, sideways to the right or left, and diagonally. The diagram on the right illustrates the queen’s awesome power.
Today’s challenge is to place eight queens on a chess board such all 64 squares are attacked and no two queens are attacking each other. To make this puzzle easy and fun, I’ve created a custom software simulation, which you can use to try to solve it yourself right here on my blog (so you don’t even need a chess set). Just click on a square below to add a queen, and keep going until you’ve placed eight queens or run out of space with fewer than eight. You can click on an existing queen to undo a placement and there’s a reset button below the board in case you want to start over. You can also click the “solve” button to have your computer quickly find a random solution (there are many). Have fun and leave me a comment if you manage to solve this one!
