The Quiz Master is part of a random event in which the player is told "It's your lucky day!" and given the option to be teleported to an unknown area to play a game of Odd One Out.
There are four questions, with three rotating items displayed. Fish is the most common item to be displayed, appearing in every question. Each question has two of one item type, and one of another. The correct selection is the one that does not match. Get four successive questions right, and the player is rewarded with either 1000 coins or a mystery box and then teleported back to where they were.
This random event is a reference to Mastermind, a longstanding British quiz show with the iconic black chair and spotlight for contestants.
