Mechanical TSD Setups

Mechanical TSD setups are repeating T-Spin Setups. They are builds that keeps repeating in one bag. The advantage of using these setups is that they are simple and easy to learn. They are similar to ST Stacking.

Repeating the same shape over and over again creates a T-Spin shape. However, because the height gets higher as more TSDs are done, you cannot repeat indefinitely.

First Bag
In the first bag, use all pieces including the T piece and stack like so.

Second Bag and beyond
In the second bag, stack like so and do the T-Spin Double. In the third bag and beyond, stack the same way. In any bag, if you get an early T, then you may do the lower TSD instead.

The shape will look the same. But it is getting higher and higher and you have a few cells in the center. If the left side is like shown in the diagram, you may do an I-Spin to fill in that gap (shown during the fifth bag).

Also, you can do a Tetris while in the loop, to lower the setup. You will need three I pieces.

Build order
First Bag

The first bag is made similarly to TKI 3. In the first bag, I and J need to come early.

Second Bag

In the second bag, you are always able to make a TSD if you use soft drops.

Third Bag

In the third bag, again, you are always able to make a TSD if you use soft drops. This time, the IO placement is different.

After that, the process repeats. Please refer to the fumen below. The fumen below shows Mechanical TSD v3 after 7 bags. code=m115@AhRpg0DeglBeRpg0BeQ4AeglCeh0BtR4hlAezhBtQ4?JeAgHvhBFqBAAA2gh0AtFewhg0BtDeRpwhg0AtCehlRpwhx?wglAeR4glg0AewhxwglR4whglJeAAAvhBFnBAAAsgh0AtDe?whBeg0BtDewhRpg0AtCehlwhRphlAtAeR4glwhAeQ4glBtR?4AeglBeQ4CexhAeg0JeAAAvhBFiBAAAigh0AtFewhg0BtDe?Rpwhg0AtCehlRpwhhlAtAeR4glQ4AewhglBtR4AeglQ4Eex?hAeg0TeAAAvhBFdBAAAYgh0AtDewhBeg0BtDewhRpg0AtCe?hlwhRphlAtAeR4glwhAeQ4glBtR4AeglBeQ4CexhAeg0deA?AAvhBFYBAAAOgh0AtFewhg0BtDeRpwhg0AtCehlRpwhhlAt?AeR4glQ4AewhglBtR4AeglQ4EexhAeg0neAAAvhBFTBAAAE?gh0AtDewhBeg0BtDewhRpg0AtCehlwhRphlAtAeR4glwhAe?Q4glBtR4AeglBeQ4CexhAeg0xeAAAvhBFOBAAAYghlAtDeQ?4BeglBtDeQ4EexhAeg07eAAA

Perfect Clear
There is a Perfect Clear after 8 lines in the third bag (71.67%). SZI is always fixed. If S comes early in the third bag, then the chance is increased to 100%.

There is also a Perfect Clear after 14 lines (10.95%).

Miscellaneous

 * Abandoning the loop: Here is an example if you abandon the loop:


 * Alternative placement in the second bag: if one decides not to use the usual form above, then they may stack like below as if they are using TKI 3.
