Millie Moreorless is an innovative new game for iPad and iPhone co-designed with children with Down Syndrome to ensure that it is inclusive and accessible for players of all abilities. As they help the space adventurer Millie Moreorless explore beautiful alien planets, players practise and develop their basic number sense.

The game is based on pioneering scientific research in the field of Magnitude, our instinctive ability to identify whether one quantity is ‘more or less’ than another – without counting. This ability is believed by some scientists to be the foundation of all subsequent maths learning.
