Nine queens puzzle

nine queens puzzle

Eight queens puzzle was one of my old puzzles. When I shared this puzzle I saw nine queens chess puzzle on wiki page.  This was a good puzzle idea and I decided to make a nine queens puzzle. Unfortunately all the solutions that I found on the web was including empty tiles. I tried to find a solution so each tile include a queen. After a few hour my sister found a solution. As you can see from photo there are three type of piece. One piece has a queen on center square. Four piece has a queen on the corner square and four piece with a queen at the center of the edge.  The distribution of tiles looks interesting.

The aim of this puzzle is placing eight chess queens on an 9×9 chessboard so that no two queens threaten each other. For solving this problem, you must place nine wooden tiles so no two queens share the same row, column, or diagonal.For making this puzzle I used 6 mm cherry wood. I cut first a 30 mm strip and after 30×30 mm tiles. I made saw traces with a hand saw. I made spots with my wood burning tool. Tiles are two sided.

This is a very easy to make puzzle. But if you don’t have woodworking possibilities you can download or preview  print and play PDF file including solution from here. (0.4 MB on secure server box.com) You can print and play or you can glue them on thick cardboard. Another easy and durable puzzle making method is printing them on full sheet label and putting them on plastic tiles.
