Polymer T-Spins

Polymer T-Spins are setups for a T-Spin Double that uses kicks other than normal T-Spin Double and T-Spin Triple and kicks the T two rows downwards. These setups are considered ineffective in most cases, but still sometimes used to fix misdrops or complicated terrains.

Iso-TSD
An Iso-TSD is built by making a shape that looks like a T-Spin Triple but the overhang is placed on the other side.


 * Compulsory: the overhang for the Iso-TSD must be at least 3 columns long and the 2 rows-wide space between the overhang and the T-Spin Double must also be 3 columns long at least or else it will not work.

Some examples on how to make an Iso-TSD. The fifth example is not recomended because it wastes a T tetrimino; a better way to deal with that field is to use Kaslideoscope.

The most efficient way to cover the overhang after doing an Iso-TSD is by spinning a J into the leftover. One could also fix it by making a Donation T-Spin if the oppurtunity to do so presents itself. A T-Spin Triple followup is used on the first example.

One could also make a structure similar to Bennxt Prop to deal with the overhang.

Neo-TSD
A Neo-TSD is made by making an overhang on one column shifted from the T-Spin Double. On some games, this will be recognized as a T-Spin Mini Double instead and does not send many garbage lines.


 * Compulsory: the overhang for Neo-TSD must be at least 2 columns long and the 2 rows-wide space between the overhang and the T-Spin Double must also be 2 columns long at least or else it will not work.

Some examples on how to make Neo-TSD. The fifth example is not recomended because it, again, wastes a T tetrimino; a better way to deal with that field is to make a T-Spin Triple.

By dropping either I or L, it might convert a Neo-TSD into a T-Spin Triple with an irregular overhang. Afterwards, use an I or L to clean up.

The most efficient way to cover the overhang after doing Neo-TSD, familar to how it is done with Iso-TSD, is by spinning a J into the leftover. One could also fix it by making a Donation T-Spin if the oppurtunity to do so presents itself. A Company Train followup is used on the first example.

One can also make a Pseudo-Imperial Cross out of the overhang which could then be continued directly into a T-Spin Triple.

Fin-TSD
A Fin-TSD is made by putting an overhang above the T-Spin Double. This one is considered to be the most effective and efficient way to make a Polymer T-Spin out of the three due to it being easier to spot the opportunity on doing so and has much more reliable continuations.


 * Compulsory: the overhang for a Fin-TSD must be at least 2 columns long and the 2 rows wide space between the overhang and the T-Spin Double must be 3 columns long at least or else it will not work.

Some examples on how to make a Fin-TSD. The fifth diagram is not recomended because it wastes a T tetrimino; a better way to deal with that field, again, is to make a T-Spin Triple.

The most efficient way to cover the overhang after doing a Fin-TSD is by spinning a Z into the leftover. One could also fix it by making a Donation T-Spin if the oppurtunity to do so presents itself. A Cut copy followup is used on the first example.


 * A possible continuation without spinning a Z is by making a Cut copy.


 * Another way is to make an Impeldown for three T-Spin Doubles.


 * On rare occasions, one might make a DT Cannon-like structure with the Z spun later after the first T-Spin Double, like May.


 * If the overhang is one column longer, then one could make a T-Spin Triple overhang first then spin a Z later.

Trehalose
Discovered by TCM-β, this setup is a Fin-TSD → Neo-TSD Polymer T-Spin.

The Polymer (Trehalose) shape. At frame 3 is a Fin-TSD followed by a normal TSD (because the step is too far for Kaidan to work). It is a Fin-TSD at frame 11, followed by a Polymer (Fin-TSD + Neo-TSD combo, i.e. Trehalose). (fumen was made by Larrytetris)

Kojibiose
Discovered by TCM-β, this is a Fin-TSD → TST Polymer T-Spin.

Ajanba Signature
Discovered by Ajanba, this is a Fin-TSD → Neo-TSD → Neo-TSD Polymer T-Spin (fumen).

Iso-Trehalose
The Iso-Trehalose is a Iso-TSD → Neo-TSD Polymer T-Spin Double.

Yogsothoth
Yogsothoth is a Polymer T-Spin cut by a T-Spin Double. This could be applied to Fin-TSD, Neo-TSD or Iso-TSD.

Fin-variant

This is a Fin-TSD cut by a T-Spin Double that looks similar to Double Triple Cannon 2.

If the top-most overhang of this variant is only one column long, this could be easily transformed into a DT Cannon 2.

Below are some structures similar to the normal Fin-variant. The one that looks like a DT Cannon is used lot of times by player Amemiya Taiyou. The one that looks like a BT Cannon is just Amemiya's Yogsothoth with the first T-Spin Double shifted one column.

Just like the normal Fin-variant, the variations above could be easily transformed to the setups those are similar to respectively if the top-most overhang is only one column long.

Neo-variant

This is a Neo-TSD cut by a T-Spin Double that looks similar to DT Cannon 2.

Below are some structures similar to the normal Neo-variant. They look similar to DT Cannon and BT Cannon, respectively.

Iso-variant

This is a Iso-TSD cut by a T-Spin Double that looks similar to DT Cannon 2.

by translocating the top-most overhang of this variant is on the other side of the structure, this could be easily transformed into a DT Cannon 2.

Below are some structures similar to the normal Iso-variant. They look similar to DT Cannon and BT Cannon, respectively.

Just like the normal Fin-variant, the variations above could be easily transformed in to the setups those are similar to respectively if the top-most overhang is on the other side of the structure.

FinT Cannon

 * ''Main Article: FinT Cannon

FinT Cannon is a setup that starts with a Fin-TSD to TST.

WolfMoon Cannon

 * Main article: WolfMoon Cannon

WolfMoon Cannon is a Fin-TSD → Impeldown → Perfect Clear setup made by player WolfMoon.

Godspin

 * Main article: Godspin

Godspin is a Fin-TSD → Neo-TSD → TST setup. This setup was made as a joke and mostly ineffective during battles.

Godless-spin
Godless-spin is discovered by player cosin307, this is a Fin-TSD → Iso-TSD → Neo-TSD → TST setup. This setup was also made as a joke and mostly ineffective during battles.
