This stacking method, discovered by fiddlesworth, produces 12 garbage lines in Tetris DS and Tetris Online (Japan), while using roughly half as many tetrominoes (15 to 21) as the common "three tetrises" opening (30 to 35).
It requires Hold piece, SRS, 3-corner T-spin recognition, and 7-piece bag randomizer.
One can perform this stack from an empty playfield if any of the following is true of the first bag of seven tetrominoes:
- S before J
- Z before L
- J before S before T (hold the J)
- L before Z before T (hold the L)
It is especially useful if their first tetromino is S or Z, but it does have a speed penalty on games with a slow soft drop (like Tetris DS).
Single-Triple-Single
T-Spin Single
Start with an S–J or Z-L:
|
Setup with S and J
|
Mirror image
with Z and L
|
Build it (S and J depicted)
Soft-drop a T and spin it:
|
Soft-drop a T
|
Rotate right
|
T-Spin Single
(2 garbage)
|
T-spin Triple
Build it more. One will need to soft-drop the S, and they will need to switch the O and Z if they got Z before O in the first bag:
|
After single
|
Drop J before O
|
Or drop O before J
|
|
After single
|
Drop I before Z
|
Or drop Z before I
|
Or drop J first, and Z before O
|
Soft-drop a T and spin it twice:
|
Soft drop T
|
Rotate left
|
Rotate left again
|
Back-to-back
T-Spin Triple
(7 garbage)
|
T-Spin Single
Make another T-Spin Single. If one's stack does not look exactly like this, do not worry. They are pretty much improvising at this point. This will send an additional 3 lines of garbage, bringing the total to 12 lines sent.
Adjusting Your Strategy
Sometimes the 2nd T-Spin Single needs to be skipped. If one has received a lot of garbage, they may need to avoid overstacking and find the quickest path to uncover the garbage and clear it away. Other times, the garbage they have received may make the 2nd TSS impossible (or may open up better possibilities):
Open Corner
This is not a 3-corner T-Spin, so no reward is given.
There is a better way to handle this situation:
Lucky Hole
Here one can make a back-to-back T-Spin Double after the T-Spin Triple with a little help from the garbage randomizer:
Continuations
There are several ways to continue making T-Spins following Single-Triple-Single.
T-Spin Double
Type A
Type B
T-Spin Triple
Type A
STS Infinity
In theory, it should be possible to continue making a stream of Single-Triple combinations. After completing the first Single-Triple combination, the path to the next combination is outlined below.
Completing the single
If a T is received early in the bag (i.e. before the Z is dropped), make the T-Spin Single immediately. The other important piece in this step is S since it always requires another piece to be dropped before it can be used. Abort this build if S and T are after Z and before an appropriate "base" for S (I, L, or J depending on the case) in this bag. The cases that use J instead of S, as shown below, carry much more risk.

The next triple
The cases have now diverged too much for each one to be outlined. However, after completing the single, the way to complete the next triple should be clear. One will likely be left with either something like this or something that can easily be built into something like this:
|
Beautiful.
|
Usable.
|
I see some promise.
|
Simply build and make the T-Spin Triple. To make the next Single-Triple combination, an S block would need to be placed and an overhang created like so:
