Chess Queen and King Problem

This game is a collection of two chess problems based on Queens and Kings.

Mode 1:

Your task is to place maximum number of Queens and Kings on a chessboard in such a way so that number of Queens and number of Kings are equal and none of these can attack each other.

Placement will be such that Queen cannot attack other Queens and Kings and Kings cannot attack other Queens and Kings i.e. Queens and Kings will have to be placed in non attacking mode.

You will win if you can achieve the configuration.
(You will win the game for a configuration of four Queens and four Kings. You can continue the game after that if you want.)

Mode 2:

Your task is to place maximum number of Queens with only one King on a chessboard in non attacking mode.
(You will win the game for a configuration of six Queens and one King. You can continue the game after that if you want.)

Queens and Kings follow the standard chess rules.

Last moved piece (Queen or King) is represented by red boundary.

Queen button is to place Queen on the board.

King button is to place King on the board.

By default Queen is selected at game startup.

Hint button will show all the possible moves remaining.
But it will not show the cells mutually under attack by Queen and King.

Green dots denote that the cell is already covered by a piece (Queen or King or both).

Playing instructions can be found from game options menu.

Undo button reverts back the last move.
Clear button clears the chessboard.

If you touch a already occupied cell it will show the cells covered by that piece by green dots.
