hard time with invisible tetris

[Obsolescence]

I can play tetris in my head with ease,  but I have a very hard time with invisible tetris. Please help/ explain?

maybe in your head, you get the pieces you need, shit i dont know. how big is the matrix in your head, are you sure you're mimicking the situation 100% correctly? abljfhjasdffdfsf d

I know i'm playing accurately in my head, but yes perhaps I'm always giving myself the right pieces.

I got a handful of tips in this thread a while back. Many people (including myself) recommend practicing in nullpomino's marathon+ level 21.
