Leo Svedjehed started playing when he was eleven years old and got stuck right away.
He quickly became good at the game Counter-Strike, or CS as it is called.
The parents have not always been so happy about the game.
They previously demanded that he had to finish school and train to play.
But now that he is a professional and can live on gambling, his parents have also let go of the requirements.
- It is not only possible to live on playing CS, it is possible to live a luxury life, says Leo Svedjehed.
Leo plays in the highest league in Sweden with the newly created team Gamingbutiken.
He was headhunted by two legends in the Counter-Strike world.
Now the team is number one in the elite series and are favorites to win the playoffs, which will be decided in Stockholm in June.
In the video, Leo answers three questions about being a computer game professional.
