Peg solitaire is a popular board game for one player. Choose a challenge problem and start to play.

Moves are made horizontally or vertically. A move can be made if a middle peg has another peg on one side and a hole on the other. In that case, the side peg jumps over the middle peg into the hole, and the middle peg is removed. The object is to remove all but one of the pegs on the board, with the last peg in the center of the board.
