A bundle of 4 games for kids of 3-7 years of age to develop logic, cognitive operations and spatial intelligence.

1. Postman - the child has to help the Hedgehog to deliver a letter to the correct house, based on the provided address.
2. Maze - find the way to the house inside a maze.
3. Sudoku (with pictures) - fill the empty cells in the table with correct objects, so that every object appeared exactly once in each row and column.
4. Rhythm - the child has to understand the pattern used in the sequence and find the object which breaks that pattern.

The author, Irina Marina is a child neuropsychologist with more than 10 years of experience and a PhD in biology. Her games are based on the materials she uses in her practice with kids.

Spatial intelligence develops in pre-school and early school period. The games Postman and Maze develop the child's ability to analyze spatial problems. The kid learns to work with pictures, schemes and maps. Such exercise helps the child to handle geometric material at school.

The games Sudoku and Rhythm develop logic and concentration which is very important for further studies at school, especially for math, computer sciences and technical/engineering subjects. While solving logical tasks, children train cognitive functions, working memory and attention which results into higher IQ (intellect quantity coefficient).

Each game has 4 levels of difficulty:
easy (3 yo.)
normal (4 yo.)
hard (5-6 yo.)
very hard (6-7 yo.)

In the Lite version all games take place on the river. The full version includes 6 locations which will get the child more engaged: forest, Egyptian pyramids, Antarctica, river, space, fantastic planet.
