SCIENTIFIC BACKGROUND
Estiball is based on the concept of "subitizing" – the human brain's ability to recognize small quantities without counting – and extends this concept to larger number sets. Regular training of this ability can lead to improved mathematical skills, faster visual processing, and better number sense.

DID YOU KNOW?
The ability to quickly estimate quantities was vital for our ancestors – whether hunting, gathering, or recognizing dangers. Today, this ability is useful in many professions and everyday situations, from mathematics and science to financial decisions.
