“Tetris is not a puzzle to be studied, but a reality to experience. You must play and flow with it.” – An adaptation of Galactoid’s Spiritual Novel Series’ Motto, based on Zen philosophy.
About the Author
Hello! I’m Galactoid, the creator of the well-known Galactoid Tetris WordPress guides. I am known by many other names, such as Ei_lara, on my Twitch Tetris streaming channel. Hard Drop Wiki has referenced my Tetris research under my former account, Malady2. Part of my advanced perfect clear research patterns also made it into Four.lol’s Tetris guide pages.
I’m a Tetris 99 main and am one of the most efficient Tetris players worldwide, having done 490,000 T-spins and having a T-spin per line clear ratio of 0.2 to 0.25 – one of the most efficient. Here’s a screenshot of my account as proof of my qualifications and experience in teaching Tetris:

Note that I never use my “Galactoid” name in any Tetris games, despite it being my most well-known name. If you see “Galactoid” on any Tetris games, like Jstris, it is not me. I use other names.
I have played Tetris since 2020, and it has become my obsession. I showed an early gift for spotting Tetris setups.
Over many years, I have researched thousands of novel Tetris methods and was the first in the world to create many guides in several areas. I’ve spent four years experimenting and testing these techniques to filter out the least practical methods, leaving only the most viable and streamlined techniques. My Galactoid Tetris WordPress website has nearly 90 guides in every Tetris skill area. It is one of the most exhaustive guides worldwide.
These are some of my Tetris feats from my mid-game when I stream on my Twitch channel below. I create them at between 1.7 to 2.2 pieces per second. Note the cleanliness and minimal T-piece wastage in the stack. These are Tetris 99 screenshots:



The above screenshots demonstrate my Tetris mastery to guide others. With 3,000 hours of playing and researching Tetris, I am in a position of authority to write this guidebook to help you master Tetris.
Layout of this Short Free Guidebook and Tetris Book Series
This guidebook series’ methods are based on observing, studying, analyzing, and compiling the techniques and strategies of high-level players such as Kazu, Amemiya, Doremy, Wumbotize, Furea, Fractal161, Blue Scuti, Firestorm, Yakine, myself, and many others.
It has the core features:
- Experience-backed content
- Principles-focused content
- Streamlined, well-structured, and clear content
- Heavy applied illustrations
Book 1 is a super-condensed and streamlined version of some parts of Books 2 and 3, designed for casual players. However, it still provides vital refreshment for players of any skill level. In those books, you will see the full extent of their depth, scope, analysis, and nuance.
All my Tetris guidebooks DO NOT use AI text or image generation.
Everything is a human product, obtained through years of laborious Tetris research, writing, illustrating, and editing.
Enjoy the Books!
I hope you enjoy my free and short book, which will prepare you for the two full-length guidebooks.
While I strive for perfection, a small number of errors may remain since the book is self-published with limited manpower. Please contact me if you spot any for a future, second edition publication!

Regarding My Desire for Solitude
As an introvert who experiences significant social anxiety, I ask that my solitude and boundaries be respected unless there is something important to discuss (like possible collaborations). I generally find it very uncomfortable interacting with traditional and larger Tetris groups, and prefer to go the solitary track. Large social interactions can be overwhelming for me.
For context on how I arrived at this reasonable approach, I’ve shared more details here, without naming any specific individuals or groups:
