I decided that I wanted to complete a "perfect" marathon game of back-to-back tetris' on ps3 tetris before I posted here. I was just wondering what the best strategy for getting a better score is. My global all-time marathon rank is 449 with a score of 706040... what is the best way to improve on this? My score pales in comparison to the higher ones! Is it t-spins? Also, could someone link me to a page that explains the acronyms that are used among those in the community?
