In chess, a queen can move as far as she pleases, horizontally, vertically, or diagonally. A chess board has 8 rows and 8 columns. The standard 8 by 8 Queen's problem asks how to place 8 queens on an ordinary (empty) chess board so that no queen is under attack by another.
8 Queens"8 Queens" is a Delphi application hosting a chess board to try for yourself and a button that will give you the possible solutions.
Start by double-clicking a cell in a grid. The program will display what cells are "taken" by this action - so that queens do not threaten each other on the next move. Continue placing your queens. You should put 8 of them.
If you fail, you can always go for the "Solve" button. This will display the list of possible solutions in a string list. Double click an item to be displayed in the grid.
