The game is aimed at kids from 3-5 years of age and develops logical reasoning, which is the ability to recognize and classify the important properties of objects.
Each round there are 4 objects presented on the screen, of which, 3 have something in common - thus uniting them into a category. Such a category always has a name (for example: furniture, toys, fruits…). The fourth object doesn't belong to that category and thus is "not like the others". For example, the following objects may be presented: a spoon, a cooking pot, an apple, and a fork. Three objects (the spoon, the cooking pot, and the fork) together are in the category of "dishes". The apple is a fruit and does not belong to the category of dishes. The task of the child is to choose the object that is not like the others.
