A California steel contractor named Mike Leyde recently displayed one such type of persistence by playing a single round of his casual game of choice, Bejeweled 2, for 2,205 hours and 51 minutes over the course of three years. In that time, he collected 4,872,229 gems, earning the game’s highest calculable score, 2,147,483,647, at which point the score display got really perplexed and went blank.
