How to make a point counter system?

Only I read the manual? XD
I like snap manual because not like other manuals, it have pictures, colors, examples.
But figure out yourself is also a good way, but you need more time to figure out than read a manual (in my opinion)

I just like the satisfaction of figuring something out myself.

Well, making a global or sprite-local variable in Snap! is the same as in Scratch

Yeah, well, I didn't make blocks in Scratch.

Well, making blocks is different between Scratch and Snap!

How? I never tried to make blocks in Scratch so I don't know.

Step 1

Step 2

Step 3

Huh, looks pretty easy.
