? oh... they are actually A.I's... I thought they were like hackers of some sort... I feel stupid hahaha. On a side note, I've been playing a lot of tetris battle on facebook and I'm level 16-17 each rank 35 and I don't know how to unlock the next pieces box... I decided to use my 5 cash they gave me to unlock one, but I want all of them unlocked.. is there a way of doing this?
