Back-to-Back S/Z-Spin Triple

Z-Spin Triple Stacking
This method of stacking allows for 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.

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.
