Peg Solitaire (1697) — The Day a Game With No Inventor Became the Math of Proving "Unsolvable"
On a cross-shaped board of pegs, you jump one peg over its neighbor and remove it, again and again, hoping to end with a single peg left. The earliest record of Peg Solitaire appears in 1697, in the French court periodical Mercure Galant under Louis XIV. No inventor is known. The popular legend that a prisoner in the Bastille devised it traces back no further than an English book from 1801, and puzzle historian John Beasley calls it unsupported by any earlier French source. In 1912 Ernest Bergholt found an 18-move solution to the classic problem; in 1982 Winning Ways for Your Mathematical Plays introduced the "pagoda function," a tool for proving certain positions mathematically unreachable. In 2007 the board resurfaced as puzzles inside Professor Layton and the Diabolical Box. This piece traces a single ruleset that has been played for over three centuries without ever needing a named inventor.
