There's some players in Warlight been in higher levels under one month so how to get to the higher level under a month

And what achivements have high points to earn in ranked games

Win coin games

But I don't have coins so I cannot do coin games yet

Win lottery games

Lottery games do help

In your specific case, it's the lack of won games that's holding you back from levelling up. It's significantly easier to level up if you actually win games, as the only things that give points are winning games, achieving achievements, and having a top 10 ladder position.

Top 10? In top 30 I get around 1000 points a day?

I know I was lacking of winning games but I enjoy warlight games and that how it is

If you're having trouble winning games, try to improve your skills.

Also, at this point your most "bang for the buck" is to complete Achievements - it only takes a couple to level, and most are pretty easy. Go chase after them!

Ask a player higher for rigged lottos

And some day you can have a body like mine.
