ZST Stacking is a Back-to-Back S/Z-Spin Triple setup. This method of stacking is arguably the easiest and most efficient way to perform Z or S-Spin Triples. Compared to normal B2B ZST/SST, this method is faster, uses less pieces, leaves no overhang, and allows for the addition/continuation of the Triples. The player utilizes SRS Roofless Kicks. Given proper stacking and flow, this setup allows for theoretically infinite Z or S-Spin Triples.

Creating the Base

Having the correct shape is important to be able to stack indefinitely. Note that these are not the only ways to create the shape, and that the first three are most likely the best/most efficient way to start the build.

2. LJT

3. LOT

4. LST

5. LLT

6. LTT

7. LOS

8. LOI

9. LIZ

10. LLZ

Recognizing the Shape

The necessary shape is a three-wide space with one block on either adjacent side.

Both options practical

Empty S/Z Triples

By the law of SRS rotation, the dotted square below must be filled for the system to register as a counted spin.

Therefore something like this performed mid-game will not count.
