The age for which the puzzle is designed.
These recommendations are rather conditional, but you still should not deviate from them — primarily because a puzzle that is too “adult” may turn out to be too difficult for a child. In addition, kits for the older age category often contain small parts that a careless baby can inhale or swallow. The main age recommendations look like this:
from 3,
5,
6,
7,
8,
9,
10, from
12 and
14 years old.
The total number of individual pieces in the puzzle.
The larger this number, the more difficult the puzzle and at the same time the more interesting it is. At the same time, a small number of parts is not always a sign of simplicity: the parts may be small and may require some skill to assemble.
The most modest modern 3D puzzles contain
up to 25 pcs. Numbers
from 25 to 50 are generally considered small,
50 to 100 are considered average, and the most extensive sets can consist of
more than 100 and even
more than 200 parts.
