When I use Kahoot in my Classroom there's always some student that says aloud "Yellow" or "Red", it's rally a simple way to spoiler the right answer to classmates! It would be fantastic if possible to randomize the position of the correct answer apparing on the different devices. For example, on device 1 the correct answer is on red position, on device 2 is in green position. This would really great not only to evoid cheating, infact using short times it's more difficult to do it, but principally to focus the attention on contents, even when cheating, it is a different way of considering learnig.
