Games in education are the teacher’s weapon to try and involve students in activities that combine the element of fun and learning with a meaning. Mobile devices have reshaped the way of teaching and have created new opportunities towards this approach.
This article will present one of the most useful tools, Kahoot! which combines beautiful graphical representations and sounds, turns the classroom into a playroom, with the teacher being the "show" coordinator and the students to be the contestants (Fotaris, Mastoras, Leinfellner & Rosunally, 2016). Students are asked to give the appropriate answer to the current question they are dealing with using their mobile devices and according to their responses they earn points that rank them in a rating scale (Wang, 2015).
