How it works
There are no points
No coins, no stars and no leaderboard. We did not forget — rewards actually make the desire to do maths smaller, and that is truest for children.
Nobody is timing you
Nobody is timing you. You may spend as long as you like on each task.
One mistake does not cost everything
You do not start over because you mistype once. The system remembers how it has gone over time.
The tasks have a code
There is a code under each task. If your teacher has the same one, the whole class gets exactly the same numbers — so you can talk about them.
