Hi Hunter,

The default case will be triggered if none of the other cases are. For example, say you had a game app, and if someone scored an 8, they got a bronze medal, if they scored a 9, they got a silver medal, and a 10 got a gold medal. Anything below an 8 got a "better luck next time" message. The easiest way to do this would be a switch statement.

    case 8:
        message = "Bronze Medal!"
    case 9:
        message = "Silver Medal!"
    case 10:
        message = "Gold Medal!"
        message = "Better luck next time!"

The default case makes it so we don't have to write out every possible case. It also protects us in case something weird happens and an unforeseen case happens.
