A year later, two new entries in the series have been released: Sven XXX and Sven 004. In 2003, Sven II appeared with different and larger levels, offering new animals such as pigs and chickens as Sven's potential love interests. Sequels įollowing the release of Sven Bømwøllen, several sequels have been developed. Occasionally, an alien UFO will appear and try to capture sheep with a beam.

A fish sheep may jump out of the water if Sven makes her happy, the player receives extra points. At the beginning, he has three lives in total, which can be increased by collecting power-ups. Sven can pick up extras in the form of flowers and mushrooms to gain special powers.

The players can always avoid the two by jumping into a pond or puddle, which will not cost a life, but results in Sven reappearing elsewhere on the screen. There are two enemies whom Sven has to avoid: a shepherd Lars Einnicken and his dog Wøtan. To clear a level, Sven must make all the white sheep disappear. After reaching a state of maximum happiness (symbolized by a heart), they will disappear, resulting in points being awarded to the player. Before they turn red, Sven can whistle to them to cheer them up. They may electrocute Sven, which, in itself, merely causes a loss of points, but will also paralyze him for a short time. At that point, they start to get angry and become red with horns, which makes them run around the field. The more female sheep wait around for their needs to be satisfied, the more their symbols shift towards a lightning. Their current happiness status is shown by a weather symbol above their head.

The female white sheep are entirely passive most of the time and await Sven's attention.

Sven is directed by a keyboard, with a special key that initiates the sexual intercourse. In Sven Bømwøllen, the player controls Sven, a black sheep, with a task to mate with all the white sheep around.
