Rank 20!!

Yeah, I've ranked up my 2P of tetris battle in Facebook! It's RANK 20!!!!! I never thought that I can play until rank 20, but I did it! But it's start difficult too when I play with the rank 20 player. Always lose to them and down to rank 19. Or just maintain at rank 20 with no ranked up again. HARD!! How can some people can play until rank 30??!! It's too difficult la~~~~~ Wanna get my 6P one ranked up to 20 too!! Fighting~~^^
