So far, we have learned about creating shapes from scratch and about different
blocks of scratch. In this chapter, we will learn about the more blocks of Scratch and
creating games in Scratch.

Blocks Shapes in Scratch

As you must have observed, the blocks in Scratch are in different shapes. They can be
divided into six types of shapes. These are: Hat, Stack, Boolean, Reporter, C and Cap.

Hat Blocks

They are called hat blocks as they look like a hat. We wear a hat
on our head, so the hat always comes on the top. Similarly, hat

blocks always come at the top of a script as they start a script.
This means that you cannot place any blocks above them.

Stack Blocks

Stack blocks are the most used blocks in Scratch.
They perform the main commands. Stack blocks have

a bowl shape cut on the top and a bump at the bottom.
This makes it easier to stack other blocks above and below them.

Boolean Blocks

Boolean blocks are condition blocks which return the values “true”
or “false” or the number “0” or “1” depending on how they are used in the script.

Reporter Blocks

Reporter blocks can hold values, which consist of numbers or

strings. If you ask, “What is 3 + 3 ?”, it will answer “6”. They have
rounded edges.

C Blocks

As the name suggests C blocks are C shaped. They are also known
as Wrap blocks. These are loop blocks to check if a condition is

true in the blocks within the loop. The C blocks are present in
the Control blocks category.

CAP Blocks

The blocks that end scripts are known as CAP blocks. They have a
notch at the top and a flat bottom. They are usually the last blocks
in the script. They are also present in the Control blocks category.
