= First Bag =

= Second Bag and Onwards = The second bag can always be built.

Third Bag
The third bag requires the Z piece before the I piece and T piece (if the I piece is placed before the Z piece, it will clear the line that the Z piece needs to sit on). This breaks Back-to-Back.

Fourth Bag
The fourth bag can always be built, and sets up a Triple Double Attack.

Freestyling the Third Bag
If the intended build fails, you can skim the line that covers the hole and then freestyle T-Spins. Some examples of freestyling are shown below.

8-Line Perfect Clear Setup
The second bag can alternatively be built the following way to achieve a Perfect Clear (or PC) after 8 lines. The build rate with the T-Spin Double is 40%, and with skimming it is raised to 66%. The perfect clear has a 95.08% chance to PC with 26 minimals. Below are some examples of the most common minimals, however with good PC knowledge, you should be able to find the solves on your own fairly easily.

DT Cannon Route
Another alternate second bag build that sets up a DT Cannon. Examples of how the DT Cannon can be completed are shown below.

Early I TSD route
Makes a broken DT Cannon, can be made if I is first or behind J and S
