A child will earn one DoodleStar for every question answered correctly in Doodle.
At the end of each exercise a child will be prompted to collect the stars that they have earned. When they do this, they will see the stars fall from the top of the screen into the the star gauge in the bottom left corner.
A child can save up their DoodleStars and use them to accessorise their avatar or purchase rewards of your choosing! Children just need to head to Stars from their Learning Zone.
