It's been over 80 years since LEGO was founded. In this article, we would like to tell you about LEGO knowledge and its history to make you able to enjoy LEGO further.

How many types of bricks does LEGO have?

A: 2400 shapes & 53 colors

According to The Cult of LEGO published in 2012, LEGO has 2400 shapes and 53 colors. Over the last few years, with the increasing new sets, like Friends and franchised topics, LEGO has more and more brick shapes and colors.

The common types of brick consist of technic bricks, basic bricks, baseplates, plates, and tiles. As for brick size, it can extend from 1x1 to 48x48. So far the brick with largest area is 48x48 grey baseplate, which is 38x38 cm in area.

P.S. There was a 50x50 baseplate. However, it was produced from 1964 to 1979 and is now discontinued by manufacturers.

How to disassemble LEGO?

A: use a brick separator

When brick separators haven't come out, people can only forcibly separate bricks with fingers or even use their teeth to disassemble bricks. This could do harm to LEGO parts and also cause danger to users. Thereafter, LEGO released separators and the most common of them are the 1st grey and green separators and 2nd orange ones.

In light of lever theory, only 2 separators can easily split up two combined tiles. Thus, I suggest every user have 2 separators. But where can we buy them? Usually, you can buy them in authorized LEGO stores. Or you can find them in the large LEGO sets as freebies.

Green separator is the old version, while orange one is the newcomer. I think the old one is more user-friendly.
It used to be hard to split them up.
Now we can easily separate them with separators!

What is the difference between 4 digits and 5 digits?

A: at first 5 digits represent classics.

There were LEGO sets with 2 digits earlier at some time. Then LEGO sets with 3 digits had been being sold until about 20 years ago. Subsequently, sets with 4 digits cam out as well. When it came to the end of 2007, 5-digit sets were revealed. These sets are mostly large, like Cafe Corner 10182, Eiffel Tower 10181, Millennium Falcon 10179, AT-AT 10178.

P.S. at first, 5-digit sets are seen as LEGO remake. In 2001, Passenger Train 10001 was released, for example. Later, they are created not as remake but as classics.

The sets starting with the first digit of 1 feature delicacy, an enormous number of bricks, and high price. Therefore, some people call this kind of sets classics. However, 4 digits are later not enough for LEGO creation, so from 2013 the basic themes, like City, started be coded with 5 digits. As a result, nobody would currently use 5 digits to represent large-sized sets.

Why is there the number of pieces noted on the package?

A: considering different merchandise laws of countries

If you pay attention to details on the LEGO box, you will notice that some packages don't show the number of pieces, while some do. In my experience, sets from the U.S. will reveal their number. On the other hand, sets from European countries may not reveal the number of pieces on the package because of various policies in Europe.

The set from Japan doesn't show its number of pieces, while that from the U.S. does. Their box contents are the same.

Why does every set have the remains of bricks?

A: for MOC (My Own Creation)

Whenever we finish assembling LEGO sets, we usually can witness the remains of bricks. This is totally normal. These pieces are mostly 1x1 round bricks, light, tiles, and technic connectors. The official doesn't have an answer to it, but we can guess this is a tradition left from early sets.

About 30 years ago, small sets mostly allowed users to play in multiple assembling ways. However, only Creator series now allow opportunities to assemble sets in various ways. But with the rest of bricks in every set, you can still make some changes in your sets for MOC. Also, these bricks could be substitutes in case that players lose their set pieces. That's why LEGO gives players these complimentary bricks.

Update: the official claims that these small pieces are easily lost, so they will give away the pieces for back-up.

The rest of bricks can be back-up pieces.

Is my minifigure original?

A: hard to tell

You might think this question is pretty obvious. But this question would become critical when it comes to minifigures. Minifigures can be classified into official, third-party, and counterfeit models. Third-party minifigures are made from official ones covered with self-made printed layers. On the other hand, counterfeit minifigures copy official minifigure designs and reproduce them, most of which are different from the originals in terms of minifigure structure and are themed as Superheros and Ninjago.

I think third-party minifigures are in the grey zone. I assume that a third-party manufacturer turns an official minifigure into its own recreated minifigure. This should be okay. But if it remakes minifigures of a series of movie characters, like deadpool and batman, under the circumstances of unauthorization this is basicallly illegal. But as a customer, we cannot easily tell if a minifigure is authorized or not.


Deadpool minifigure was the most popular third-party minifigure.
