The Goal of This Guidebook

I have written this book to improve and polish the canonical T-spin setup chapters in Books 2 and 3. Around 45 to 50% of the content is new.

These are popular T-spin setups, including DT Cannon, Fractal, Imperial Cross, Trinity, and STSD. Hence, they are core, essential, and practical mid-game methods that every serious Tetris player should master.

I also included slightly rarer, yet practical methods, such as Fin T-spins, Grim Grottos, and Impeldowns.

Such a low-stakes update (rather than creating the second editions of Books 2 and 3, which total 1000 pages — too much work!) through this rather short Book C is important, as Tetris is constantly evolving in its strategies.

I wrote this book to heavily supplement my How-to-Tetris video tutorial series at my Galactoid Tetris YouTube channel. Search for this playlist’s title in my channel:

As of August 2026, I have created 86 Tetris tutorial videos, making it the longest and most comprehensive Tetris video guide playlist, with nearly 12 hours of footage.

As you read this book, please refer to my How-to-Tetris videos on YouTube for each method. Hence, for the chapter dedicated to “DT Cannon,” please search and view the corresponding video.

The synergy between this book and my videos will complete the Tetris experience.

While I strive for perfection, a few errors may remain, as the book is self-published with limited manpower.

One Big Question

Q: Do you earn any money from this book?

A: Not a single cent. It’s free on this website, but you can buy the physical book when it’s out on Amazon to support me financially if you like.
