During the Bonus Round, Rules are added every time the player advances down a floor. This causes the rules on each floor to change dramatically between playthroughs. Some of these rules make the game harder, while others can help make the game easier or just simply change the rules in an interesting way.

There are two options when going down a floor: a rule that is already set up for you, and another rule from the list chosen at random. Certain rules are more common than others, and some rules, like Wicker Man and Buster, will not show up together in an episode.
