Peg Solitaire is a single-player board game that involves moving pegs on a cross-shaped board. The objective is to remove all but one peg by jumping over adjacent pegs, similar to the game of checkers. Each jump removes the peg that is jumped over, and players must strategize to ensure they can continue making moves. The game starts with a specific arrangement of pegs, usually with one empty space in the center. Players can only jump horizontally or vertically, and the game ends when no more moves are possible. Peg Solitaire is a classic puzzle that challenges logical thinking and planning skills.
