Tetris Perfect Clear Study - Phase 1
I will be sharing this study as a PDF soon as well, but in the meantime, it's much easier to "flow" through the study in a web page. Simply click the link below, "open" or "run" the file when prompted (this should be opened with your default browser, or Internet Explorer if there are any loading issues). Once you have the document open in your web browser, be sure to "allow the blocked content" so you can view all of the contained information. Also, once you are viewing the document, don't miss the tabs at the bottom. The document defaults to the Preface tab, and there is also an Original Collective tab.
This study will be discussed in further detail on the Hard Drop forums in this thread:
