🚧 This page is a work in progress. As I learn more I will add to it. Please be nice 👷🏻♀️
I am not an expert in T-spin triples. I am creating this as a reference to help me learn so please keep that in mind while reading. 🙏
I mostly created this page because they say you can learn by teaching, so here we go!
If you think this page lacks information and you'd like to help me get better at TST's and contribute some advice, feel free to join me on Discord in the #tetris channel where we try to help each other learn new fun tricks for all Tetris-related games.
Lone Mino TST (aka the "notch") examples
When there is a single, isolated mino 1 spot away from the wall, you can set up a TST. This works if it's 2 away too, but it's a bit harder to build because you need line pieces.
The images below show alternate versions, e.g. mirrored ones.
This notch/lone mino does not need to be at the very bottom. This can be done in the middle of the board as well.
L and J overhang
In the below image, the overhang is created with J and L pieces, and the O piece is used to help set it up.
Z and S overhang
In the below image, the overhang is created with S and Z pieces.
Clean board, extra T pieces
I wouldn't normally use T pieces to build out a TST but sometimes you have a few extra. I've seen this after doing a PCO before. You can use a T piece and either an L or J to set it up, then fill the space, and add the overhang. In this case you'll need to slide it in before spinning since there's no wall (unless you add one).
I will update this post with other methods as I learn them. Here is a helpful reference: four.lol/methods/tspin-triple
