silver up

im silver 2 .. i win 10 game. but i didnt up my rank.. what the system of rank game

The ranking system is a bit weird, I'm currently on a 11 game win streak and I've been flying through ranks. I started off as Silver 3 ( I bought the account like that ) and I've been grinding with friends and currently I'm Nova 2. You'd get used to it, dw.
