TKI 3 Opening

With an I tetromino early in the first bag, you can try a TKI opening, invented by Tetris DS player TKI. Given the right pieces, it allows for three T-Spin Doubles and a T-Spin Triple to finish. This is a good setup since it uses all pieces in a good balance, as well as not wasting your T.

Here is the basic TKI-3 Opener. Beneath are some variations on the setup. Throughout these, however, the basic setup remains the same.

 * Example of 3 TSD


 * TKI 3 TSD Opening with TST Finish


 * Imperial Cross: The forth diagram is preferred becuase you will have a chance to make a Perfect Clear (89%).

If Perfect Clear is not possible, one may build another T-Spin Double, Imperial Cross or Fractal.


 * Perfect Clear after 6 lines: In the third bag, O or L must come early.

TKI 3 (Flat Top variation)
Alternate way to make the Flat Top variation:

 * T-Spin Double


 * ST Stacking


 * Donation


 * Single Double (SD1)
 * Super T-Spin Double


 * Back-to-Back T-Spin Triple


 * Double Triple Cannon: A DT Cannon followup. Theoretically may result in a PC.


 * Blink SZ Prop: It may also lead to a Perfect Clear after 6 lines (diagram 5) if you can hold the J piece.

If Perfect Clear is not possible, one may make another T-Spin Double like below and then continue with another TSD or 4-wide. A Perfect Clear after 10 lines is also possible.


 * Imperial Cross: The second diagram is preferred becuase you will have a chance to make a Perfect Clear (98%). The solutions are the same as above.


 * Perfect Clear after 6 lines


 * Perfect Clear after 8 lines: Although there are other ways, this way is the easiest to memorize because it has three solutions.

Continuations

 * Perfect Clear after 6 lines: In the third bag, O or L must come early.

If Perfect Clear is not possible (e.g. O or L came late), one may stack an STSD.

TKI 3 (Snail variation)
Also called Trustworthy DT. Try this variation when the O piece comes late in the first bag.
