Solitario

The situation puzzle known as Game of solitaire backs to the 18th century. Its origin is unknown, although some authors attribute it to a French count that used it while being imprisoned in the Bastille.

At the start of the game, the central square must be empty. During each go, the player has to move one chip over an adjacent one, that is taken off the board just as in checkers. The moves can have any direction except diagonal.

The objective is to get rid of every chip except one, that in the end must be in the central square.

The minimum number of goes to solve it known so far is eighteen, taken into account that a series of moves made with one chip makes for a single go. Here you can find a solution for the situation puzzle in 27 movements.
