Paste the options, or the class list, and spin. The wheel is drawn big so the whole room watches the same thing slow down.
Put the options in the box, one per line, and press spin. It works for names, for topics, for who presents first, for which question to do next. The wheel slows down instead of jumping to an answer, because the slowing down is the part the class enjoys.
Tick the box and each winner is taken off the wheel, which turns it into a rotation rather than a lottery. That is usually what you want with a class list.
Learnify turns the class into a role-playing game run from the teacher's screen: points for real reasons, avatars that evolve, attendance, groups and quiz games. Pupils need no devices and no accounts of their own.
