How scores are calculated?

Good evening everyone. I am an Italian amateur player and my nickname is pgft. It is the first time that I write on the forum. I would like to know how the scores are calculated in case of victory or defeat. Also, I would like to know what the question mark next to some players' score means. Thanks for your attention and good games to everyone.

How do you pronounce your nickname?

That is also my question.

I saw the pronunciation on Google. It simply calls each alphabet!

must be an acronym, or some tongue twister. lucky it might have not been taken with so few characters. wonder how old is the account... what are the odds. 26x4 + 26x3 + 26x2 + 26 (or whatever alphabet) accounts 1 over that if people were all preferring smaller handles (maybe more odds depending on restrictions). or the 100 magnitude.

maybe this is meant not to be remembered, as difficult to pronounce (we all do sub-vocalization, to some extent, right?)
