Solitaire refers to a range of games that are typically designed for a single player, hence the name.

In the USA – and almost everywhere else, largely due to its implementation on personal computers – the card game known as Solitaire is actually Klondike, which is also known as Patience in the United Kingdom. In the UK, "Solitaire" typically refers to Peg Solitaire.

Peg SolitaireEdit

Peg Solitaire consists of a cross-shaped set of holes, in which pegs are housed. The pegs are sometimes replaced by other markers, such as marbles. The central hole of the grid is empty at the start of the game. The aim of the game is to remove all but one of the pegs from the board. Pegs are removed by "jumping" an adjacent peg over it. The "jumping" peg must move into a space on the opposite side of the "jumped" peg, and the move is obviously not valid if the space is occupied. It stands to reason that it is generally advisable to avoid creating too many separate clusters of pegs, as this will eventually result in isolated pegs which cannot move closer to one another, resulting in failure. Given that the number of pegs to be removed is the same every time the game is played, and that every move removes exactly one peg, any solution will always take the same number of moves.
