What is the number?

[Akuma]

I entered some number here, and its up to you to guess it.

Everyone can make 5 guesses, but the reward will be bigger if you manage in less tries.

According to the size of this black "square" you can make an educated guess how many spaces number can have.

I will reward the one who guess it first. I will also post a proof (this same screenshot without the black square, there is also a timestamp there).

Edit: don't just tell me I spent my two attempts

[Akuma]

the answer is taking 2 spaces, I guess I overdid it with the square lol
