How does the scoring work in leagues ?

Hi , 
How does the scoring work in leagues ? 
15 for a win ?
Do you get anything if you loose ?
And 5 of a draw ? 

I have noticed some people are on odd numbers like , 27 , 17 , 19 ..etc , how has that happened ? 
I guess , if you get say 3 point for a loose , maybe 

Hi T-jankins9522 , 
How do I know which I am playing ? 
I normally , in fact always play 10min rated games . 
rapid is 10min games or is that blitz? and bullet is 1 min games , yea ? 
That may sound silly , but I use to have a score of 1200 -1300 (don't on what) but that has dropped massively to 900 -1000 , sometimes even touching on the high 800s

Thanks

Hi T-jankins9522 ,
Sorry to bug you , but just played a game , it was 10mins , so that is a Rapid , but the clock was white , what does that mean ? 
Also , just so I am not being silly , you do mean the stop watch counting down , yea ? 
Is the a user guide on there on how and what things mean . Not on how to play chess , but the interface

Also I noticed , that for a win , I scored 9 , but for the league it adds 15 , this is for the same game i mean .

Make it for King Of The Hill, please.

Variants were removed from leagues early on and likely won't get added back. It was too easy to get a lot of trophies really quickly.
