Mini Golf Castles allows up to four players to compete on medieval themed courses, each consisting of nine holes. At first, only one course can be selected, two others can be unlocked through tournament play. Four characters are available for visual representation. The aim is visualized by a punctured line indicating the direction of where the ball will go, the power of the shot is simply controlled by a button press and showed on a bar. There is an eight-stroke limit per hole. Some of the challenges are in tune with the medieval theme, like putting the ball at the right moment into a hole while an armour suit puts a sword down.
