Infinite Luck

Sam has always been lucky. Every game he plays, he always wins by sheer dumb luck. He was never injured seriously, cause every time something bad would happen to him, it is simply luckily avoided. When he needs something but doesn't have the means to get it, he randomly bumps into it, with no apparent owner no matter where he searched.

His luck was so absurd that even the gods noticed him. It was then and there that a new game was born between those deities: who can end Sam's luck once and for all.
