I can't remember much about this scifi short story (part of a book of stories). It must be at least 30 yrs since I read it.
There was a space invader machine which was white with a spherical white control and no other buttons. I think it was in a dusty old shop with a sinister shop keeper. The main character was a boy (I think) and he had some kind of disquieting/disturbing experience when playing the game. It might have been that it connected him to an alien planet?
