This game is an example of "Pasapalabra", also called "Alphabetical":
It is perfect for a revision exercise and it can be carried out in class despite the current pandemic situation, as it does not invove any physical contact.
You can play as a whole group (you split the class into two teams and the teacher is the one reading the questions and keeping track of time) or you can split the class into small groups (you may need one tablet or phone per small group to share the link), if you decide to organise students in small groups, one is the judge (or TV presenter) and is the only one touching the screen, asking the questions (he/she should have the key) and keeping an eye on the time, and the rest of the group is divided into competing teams.
Thanks to @saraofer, you can use this reusable genial.ly template so that you can change whatever you wish. Click on the photo:
