"King of the Bingo Game"

When the narrator of the "King of the Bingo Game" says the quote ...
"“he felt vaguely that his whole life was determined by the bingo wheel”;“the unlucky cards and numbers of his days”“he felt that the man was making a fool of him”“as the wheel increased its speed it seemed to draw him more and more into its power, as though it held his fate; and with it came a deep need to submit, to whirl, to lose himself in its swirl of color”“This is God!”

I believe the wheel is discussed in these terms because it feels to the protagonist that winning the jackpot determines his life. Laura seems to be the love of his life, and if she is dead, then he has nothing to live for. The jackpot money will help pay for the doctor's bills, hopefully curing Laura from whatever sickness she has. By comparing the wheel to God, the protagonist is stressing how the money from the jackpot will change his life forever, just as God changes the lives of people.

I think at the end of the story, the protagonist did not win the jackpot and probably went crazy. His sexual thoughts from the beginning of the story hint that he might be "sick in the head" and this jackpot might have been his trigger for him to go crazy.
