It has some skill, but it's all rather complicated. The main factor is whether or not the "evil" tag is set. This is an invisible value that rigs the second and third slots. It makes the second slot stop immediately as oppose to rolling on to the next one, whereas the third slot not only skips forward one from the icon you would have got normally, it also stops you from getting three in a row. The chances of the evil tag being set are based on the first slot's face value (the "higher" it is the more likely the evil tag is set) and your current play time in seconds.
