The author of the games is a child psychologist with more than 10 years of child educational experience.

Spatial intelligence develops in preschool and in early grades. The games "Postman" and "Maze" develop help develop a child's ability to analyze spatial problems. The child learns to work with pictures, patterns, and maps. Such exercise helps the child to handle geometric material at school.

The games "Sudoku" and "Rhythm" develop logic and concentration, which are very important for further studies at school, especially in math, sciences and technical/engineering subjects. While solving logical tasks, children train cognitive functions, working memory, and attention; which results in a higher IQ.
