Mystery boxes can be obtained from the Quiz Master random event. Players can choose between 1,000 coins or the mystery box upon successfully completing the random event. The box contains a random selection of items. It is also possible to receive nothing. The message in your chatbox will state "Inside the box you find absolutely nothing! What a shame."
