Peg Solitaire

What is Peg Solitaire?

Peg Solitaire is a solo jump puzzle, also known as Kongming chess, Solo Noble, Solo Goli, Marble Solitaire, or simply Solitaire, where you hop one peg over a neighbor into an empty hole, remove the jumped peg, and keep going.

You start with every allowed hole filled except the center. Chain straight-line jumps until only one peg remains—ideally back in the middle. Helper hints and the auto-solver can steer you toward clean runs.

The first printed mention shows up in 1697 at Louis XIV's court, where Mercure galant outlined the cross board, rules, and sample drills.
