Yes, I’m really spending 18 minutes talking about rotating blocks.

And I don’t regret it one bit.

However, what I do regret is releasing this video with a rather poorly researched T-Spin chapter. I am not proud of that part and would like to apologize for any misinformation it may have spread. You can find corrections in the pinned comment below.

Chapters:

0:00 Intro
1:44 The Tetris Games of Old
3:23 One Ruleset to Rule them All
5:03 The Super Rotation System
8:35 The Art of the T-Spin
14:12 Modern Tetris Masters
16:08 Conclusion
