All 16 games

Running this with a class?

Open a room, put the code on the board, and everyone plays the same questions at the same moment — thirty phones, no app, no logins for the children. Afterwards you get the part a leaderboard never shows you: which question two thirds of the room got wrong, and what they put instead.

Set up a teacher account Free. Children never need one.

The games are one part of it. There is also a planner, a paper builder and a few hundred worksheets — all free for your own classes.
