T-Spin Single Triple Single

This stacking method, discovered by fiddlesworth, produces 12 garbage lines in Tetris DS standard vs. mode while using roughly half as many tetrominoes (15 to 21) as the common "three tetrises" opening (30 to 35). It requires Hold piece and SRS.

You 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 your first tetromino is S or Z, but it does have a speed penalty on games with a slow soft drop.

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)

O before Z

Z before O

Soft-drop a T and spin it:

Soft-drop a T

Rotate right

T-spin single (2 garbage)

Build it more. You'll need to soft-drop the S, and you'll need to switch the O and Z if you got Z before O in the first bag:

After single

Drop J before O

Or drop O before J

Soft-drop a T and spin it twice:

Soft drop T

Rotate left

S00per Rotation

Back-to-back T-spin triple (7 garbage)

And it leaves room for a back-to-back T-spin single (3 garbage).
