After mastering these things, move onto learning advanced tricks such as left rotate and finesse. This is where it gets interesting and where Tetris seems far more advanced than most people’s play. For example instead of moving the O piece 3 to the right, you are supposed to hold right until it reaches the right side of the field, then move it back 1. Left rotate brought me from 1 minute to sub-50. Guess how you learn these? Again, practice. Take it slow.
The first time you use left rotate do not expect to come close to your regular times. I went from 1 minute to about 1:30 average on a good game the first day I tried this
