Quiz Monster is an educational massively multiplayer online role-playing game (MMORPG) that allows students to review the learning material. It is a quiz-type battle that encourages learners to participate so that they can better retain the information on what they have learned. The game is played in the same classroom environment as 2-View in ELiF, and a separate application, rather than the application for ELiF, is used. The game can even be enjoyed by students on their own smartphones.
