"In this game each player has a Knight which moves as in Chess. However, once a piece has moved, the square it was previously on cannot be entered again by either player. The Knights cannot capture each other. The object is to leave your opponent without any moves.
Joust features five levels of computer opponent, and can also be played by two human players. The computer opponents range from the randomly-moving 'Gorilla' to the very strong 'King', but all are beatable if you persevere.
I don't know who invented this game. I came across it as an ancient Amiga PD game, although in that version the pieces started in a fixed position in the centre rather than being randomly placed on opposite sides of the board. As well as the game of Joust, the program allows you to try the "Knight's Tour" puzzle for boards of size 5x5 up to 12x12."
