Peg solitaire is a board game for one player involving movement of pegs on a board with holes. 
        Some sets use marbles in a board with indentations. The game is known simply as Solitaire in the United
        Kingdom.
    
The standard game fills the entire board with pegs except for the central hole.
            The objective is, making valid moves, to empty the entire board except for a solitary peg in the central
            hole.
            A valid move is to jump a peg orthogonally over an adjacent peg into a hole two positions away and then to
            remove the jumped peg.
