A Nintendo computer game that allows players to practice their golf swing or fine-tune their tennis stroke in their living room has won six Bafta awards.

The Japanese company's top-selling title Wii Sports swept the board at the British Academy Video Games Awards in central London.

It was named best sports game and picked up five other awards, including best gameplay, innovation and strategy.

Unlike most consoles, Nintendo's Wii uses a wireless, motion-sensitive controller that can be used like a golf club, tennis racket or baseball bat.

Wii Sports lost out in one of the main categories, beaten to the best game prize by BioShock, an acclaimed first-person shooter set in a dystopian underwater city.

Two other games both picked up two prizes: organized crime thriller Crackdown (action and adventure; use of audio) and the Greek mythology game God of War 2 (story and character; technical achievement).

The British Academy of Film and Television Arts is best known for its annual film awards, sometimes referred to as the British Oscars. It has awarded prizes to the year's best video games since 1997.
