When you first start the game, a chessboard and 4 randomly generate chess pieces ranging from a pawn, queen, rook, horse,etc.,  are place randomly on the chessboard like the image to the left. The objective of the game is to have one piece remaining on the board.  There's only one rule similar to chess which is that the pieces move the exact same way in regular chess, i.e., the bishop can only move diagonally. There are restrictions to the game such that you cannot move your piece in an empty square, or violate the one rule similar to chess.  You can select any of the 4 pieces to start the game, but remember you only want one piece remaining so the player must keep in mind how the pieces move in order to win. 

The reason I choose this game because I like chess and puzzles.  This game takes both of those elements by randomly generating 4 chess pieces and placing them randomly on the chess board. From here you try to figure out how to get one piece remaining for the game. I like the chess aspect of them game, where you can move the chess piece, but just like chess you can only move certain pieces in certain direction. Additionally, I like the puzzles aspect of the game where you try to figure out how to move each of the chess pieces in order to get one piece remaining.
