What a level is like

Every level is 10 questions long and takes a few minutes. Questions are read aloud in recorded narration rather than robotic text-to-speech, and answers are tapped, dragged or typed on a number pad rather than written, so a child who is still learning to read can play unaided.

Most dojos open with a short lesson before the questions start. Get one wrong and the level teaches the step you missed before showing the answer, and you can play the level again — the questions vary on each replay, so it is practice rather than memorising a fixed sheet. Levels are scored out of three stars.
