Peg Solitaire, Solo Noble, Solo Goli, Marble Solitaire or simply 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 as solitaire in Britain and as peg solitaire in the US where 'solitaire' is now the common name for patience.

Board games are tabletop games that typically use pieces. These pieces are moved or placed on a pre-marked board and often include elements of table, card, role-playing, and miniatures games as well.
