Halma was invented by George Howard Monks, a US surgeon at the Harvard Medical School.

This traditional board game is played by two or four players seated at opposing corners of a board that is divided into 16×16 squares. The game is won by being first to transfer all of one's pieces from one's own camp into the camp in the opposing corner. On each turn, a player either moves a single piece to an adjacent open square, or jumps over one or more pieces in sequence. Moves can be orthogonal and diagonal.
