I can't recall which match that ended this way sometimes last month for a close relative, who was already rejoicing that his game is playing base on how it has been predicted it was already on the last minute or the match, and the referee gave extra time of about 3-5 minutes, which gave the other team a chance to equalise the winning team, which was just how the entire bet was ruined. It's something that happens frequently; the game can change in every little second. We can't be too sure; that's why some people just consider cashing out and saving themselves the stress than getting that high heartbreak of dying minutes winning.
