N-Queens is a straightforward chess-based puzzle game. Try to fit as many (or as less) Queens as possible on the chessboard.

N-Queens features two modes of play. The maximum N-Queens problem challenges you to place N queens on an NxN chessboard without threatening each other. To start, it is a good idea to try with a smaller board and then work your way up to the larger size 8x8 board. There are many possible solutions for boards with N higher than 4.

The minimum N-Queens problem is about placing the least number of Queens on the chessboard to threaten all squares on the board but not endanger themselves. The same recommendation is made here as above, start on the smaller board.
