Potatospin

Under Construction

Potatospin is a Trinity opener setup created by sin90equals1 and Evim6‎. The 1st bag is identical to that of Aromatic Baby with a T-Spin Single. This is followed by a Trinity in the 2nd and 3rd bags, with possible continuations to Mechanical TSD or a 14-line Perfect Clear. This opener preserves Back-to-Back from the beginning through the execution of the Trinity, and will send at least 18 lines to the opponent in the first 3 bags. Attack can be boosted by saving the T-piece in the 2nd bag and using it to spike with the 3rd bag.

First Bag

The build chance of the first bag is 56.67% regardless of whether the mirrored setup is considered.

Notice that the I can always be placed regardless of whether the J or L have been. If both the J and L have already been placed, the I can still be spun in.

Second Bag

Normal Build

This build is always possible with an early L. The T can also be saved to be used in the third bag instead for spiking purposes. The build chance is 66.67%.

It is also possible to spin the T differently (Trinity TSD Declined), yielding a T-spin mini single in the second bag and a Triple Double Attack in the third and forth bags. The third and fourth bags are stacked identically to the normal build.

Alternative Build

If the normal build is not possible due to an early J and T, in most cases, the J may instead be placed on the right side of the board. However, this is undesirable because the overhang for the Trinity will need to be created in the 3rd bag, which is not always possible to do without wasting a T.

Alternatively, if the normal build is not possible, the player can always stack one of the 2nd bags of Aromatic Baby instead. This is usually better than going for the alternative build described above.

Third Bag

Normal Build

There are many ways to finish the setup using the first few pieces in the third bag. (PC solutions coming soon)

Afterwards, the player is left with an opportunity for 2 TSD's.

Alternative Build

The overhang for the Trinity can be created with a Z or S piece as well as with O and J or L (a T can also be used if absolutely required).

Not recommended

Similarly, the tub on the right can be filled with a Z, O, J, L, or I and S.

Aromatic Baby

The 3rd bag of Aromatic Baby sets up a TST tower. This particular build has two different possible setups.

Note that in some cases, the I piece will need to be spun into place.

Continuations

Normal Build

In the third bag, one may opt for an STMB cave instead with a 68.77% build chance. This leaves behind a convenient board for a Mechanical TSD v2 setup beginning with the 4th bag.

Perfect Clear

After the 4th bag, a 14-line Perfect Clear is also possible with a PC chance of 89.88%. The full set of minimals is shown below in decreasing order of build chance.
