Wordwall is a brilliant collection of activities that language teachers can easily create and share with their students. Here are two video tutorials about Wordwall by Russell Stannard. The first, from 28 September 2020 is for beginners. The second, from 1 October 2021, is more advanced (and very impressive).
The games and exercises in Wordwall can appear in many formats. To make sure your students receive a usable format, go to the game you create in a different browser and see what you students will see.
