Halma is a board game invented in 1883 or 1884 by an American thoracic surgeon at Harvard Medical School, George Howard Monks. The inspiration was an English game called Hoppity.
Playing equipment consists of a checkered board. Pieces are typically black and white for two-player games, and of various colours or other distinction in games of four players, placed on opposing corners of the board. The goal of the game is to transfer all of one's pieces from one's own camp into the camp in the opposing corner. Each turn, a player either moves a single piece to an adjacent open square, or jumps over one or more pieces in sequence.
