Yeah sorry, I'm guessing you never played Tetris before or if you did, not seriously. You just have to practice. Eventually you will know the different orientations of all the pieces and will be able to look at the next few pieces coming up so that you aren't surprised about what pieces come up. I can do it using peripheral vision by the color of the piece. I make sure I can place the next piece before I place the current piece. You also need to work out what patterns are more helpful than others. Level 15 is a bit fast though, you really do need to keep the stack low.
