Queen’s Game
In David’s chess class, the instructor asked students to arrange “8 queens” on a chess board, without any queens attacking each other.
In other words, it is a game of positioning 8 pieces on a 8 by 8 board. On any row, any column, and any diagnals, there should have at most one piece. (If more than one piece, they are fighting with each other.)
You can try it to see if you can find any such positions. If you can find one or two such positions, you are pretty good. But if you want to figure out how many possible positions there can be, that is for sure very challenging. You must be a genius if you can figure it out by pure analysis.
I has coded a program which can tell you all the possible positions in a second. You can download the zip file queengame.zip. It will show you a total of 92 positions.
