TKI 3 Opening

With an I tetromino early in the first bag, one 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 their T.

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

 * TKI 3 TSD Opening with TST Finish


 * Imperial Cross: The fourth diagram is preferred becuase one 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: Yet another way to place pieces in the second bag resulting in a chance for a Perfect Clear.



TKI 3 (Flat Top variation)
This way involves placing the J piece upside down on top of the Z piece (there is another way as shown in the first picture).

 * 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 one can hold the J piece and I comes early in the third bag.

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


 * Imperial Cross: The second diagram is preferred becuase one will have a chance to make a Perfect Clear (89%). The solutions are the same as above.


 * Perfect Clear after 6 lines: If one can hold J and I from the third bag comes early, it is possible.


 * 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.

Below is an additonal way. Either I or L should come early in the third bag.

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