Age
Age recommendations are rather conditional, but it is still not recommended to deviate from them. So, building blocks for older children may contain small parts that a curious little child can swallow. At the same time, sets for little ones are easy to assemble and uninteresting for adult children. And an age-appropriate construction set can be too complicated and uncomfortable, upset or even scare the baby.
Note that the age category to some extent also characterizes the maximum age at which the constructor can be useful. For example, a set for
1+ and
2+ is unlikely to attract an
8-year-old or even a
7-year-old elementary school student, and a complex design of
14+,
16+ and even
18+ often turns out to be interesting even for adults over 30 and even over 40. However, even within the same age category, much depends on the characteristics of a particular set, in particular, on the type of game. And there are options for designers for any age. In addition to those listed above, there are also
3+,
4+,
5+,
6+,
9+,
10+,
11+,
12+.
Number of pieces
The total number of parts included in the delivery of the designer. At the same time, the calculation, usually, also takes into account the details that make up individual characters (torso, arms, legs, head, etc.) — despite the fact that the figures are most often delivered assembled and are not designed for disassembly during normal use . Also note that the kit may include several spare parts, in case of breakage or loss of any of the main elements.
Moving elements (mechanics)
Details and elements that, after assembling the designer, can move, but are not driven by a motor; in other words, moving parts that need to be moved manually. These can be, for example, windows and doors, hatches, screws, crane booms, etc. The exception is rotating wheels — in this case they are not considered moving elements.
Mechanical moving elements can be combined with motorized ones (see below).
