Each round there are 4 objects presented on the screen, 3 of which have something in common— thus uniting them into a category. The category always has a name (for example: furniture, toys, fruits). The fourth object doesn't belong to that category and is "not like the others"—the kids need to identify it.

Categories of objects found in the game include toys, dishes, tools, clothes, school supplies, flowers, mushrooms, fruits, vegetables, sweets, mammals, birds, insects, and marine creatures.

This logic game systematizes the child's knowledge about the world, and improves the ability to abstract and solidify concepts.

Teachers and parents can download and install the game for free on their Android phones or tablets.
