Polymer T-Spins are setups for a T-Spin Double that uses kicks other than normal T-Spin Doubles and T-Spin Triples 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.
Classifications, Basic Setups and Continuations
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.

|
Compare an Iso-TSD with a T-Spin Triple with an irregular overhang.
- 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 at least 3 columns long.
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 arises. A T-Spin Triple followup is used in the first example.
One could also make a structure similar to Bennxt Prop to deal with the overhang.
Iso T-spin Triple (TrIso)
This kind of TST is rarely used. It can only be done on games which have 180° rotations and SRS 180° kicks, like Tetr.io (but not Jstris). It was first showcased by OctoCallie during the Garbo Gamble Cup tournament as a different continuation of the DT Cannon.[1] Yackspin is an opener that uses this technique.

Neo-TSD
A Neo-TSD is made by making an overhang on one column shifted from the T-Spin Double. On some games, this would be recognized as a T-Spin Mini Double instead and does not send many garbage lines.
- Compulsory: the overhang for the 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 at least 2 columns long.
Some examples on how to make a Neo-TSD. The fifth example is not recomended because it, 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, one 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 arises. A Company Train followup is used on the first example.
One could also make a Pseudo-Imperial Cross out of the overhang which could be then continued 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 the most reliable continuations.
- Compulsory: the overhang for the 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 at least 3 columns long.
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, 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 arises. 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. This uses the same concept as WolfMoon Cannon.
- On rare occasions, one might make a DT Cannon-like setup which results in a May setup afterwards.
- If the overhang is one column longer, then one could make a T-Spin Triple overhang first and then spin a Z.
Setups
Trehalose
Trehalose is a Fin-TSD → Neo-TSD Polymer T-Spin, discovered by TCM-β.
Empty Field Setups
Empty Field Openings, created by the player Larrytetris.
Midgame Opportunities
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). The fumen was made by Larrytetris.
| Pros: | Cons: |
| "It takes very few keystrokes to set each piece in place, and you can even take advantage of DAS/ARR repeat across pieces for the OIL." - Larrytetris. |
"They are impractical and dangerous in modern multiplayer and will always remain an outside quirk of a blanket rule, in my book. The stack for them is not flat, and for the number of lines taken to do one (including the high overhang, which is I assume easy to get spiked on), their send-attack ratio is poor. With the number of pieces used, a normal t-spin double is nearly always better, and a tetris cleaner and less risky." - Paul676 |
Kojibiose
Kojibiose is a Fin-TSD → TST Polymer T-Spin discovered by TCM-β.
Ajanba Signature
The Ajanba Signature is a Fin-TSD → Neo-TSD → Neo-TSD Polymer T-Spin, discovered by Ajanba. (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 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 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 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 overhang is on the other side of the structure.
