Super T-Spin Double

Super T-Spin Double or short STSD is a technique that results in two T-Spin Doubles. The technique is often used in mid-game. It can also be used as an opener but receiving garbage with a hole in the wrong column will break the T-Spin execution (wrong column means the third column from left respectively right in most pictures below).

Basic Setup

Empty Field Setups

Other Setups

T pieces are not required in the upstack of these setups. Hold the T pieces until one is ready to clear both T-spin doubles.

I base, O overhang

IO base, S overhang

JZO base, S overhang

IJ base, L overhang

STSD with T Base

Because a T piece is used in base these setups, the player must wait until at least the 3rd bag before having both T pieces required for clearing the STSD. By this point, there will be a decent 2-wide above the STSD (see discussion below).

General Tips

An STSD setup can be used over an empty column. This can be very useful when approaching rows that are too high to set up a TSD or if the player wants to sneak in a second T-Spin Double. When used in combination with tetrises, this technique can be very deadly.

When placing an STSD over a tetris column, a player can still tetris if the notch has not been set up.

Notch is not OK.

Overhang is OK.

Advanced Tips

STSD setups can be stacked

Similarly, the STSD can be used as a funnel for other T-Spin setups. This can be useful during a T piece drought. The following example is an STSD on an Imperial Cross.
