Revision as of 11:29, 5 May 2021
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. The first three diagrams show the initial opener and the last diagram shows a variant.
Castle Top |
Fonzie |
Flat Top |
Sub-variant |
Castle Top variation
Continuations
- TKI 3 TSD Opening
- Imperial Cross: The fourth diagram is preferred because one will have a chance to make a Perfect Clear (89.68%).
If Perfect Clear is not possible, one may build another T-Spin Double, Imperial Cross or Fractal.
T-Spin Double |
Imperial Cross |
Fractal |
- Perfect Clear after 6 lines
|
O |
T |
Z |
S |
I |
- Perfect Clear after 6 lines + T-Spin Double: Yet another way to place pieces in the second bag resulting in a chance for a Perfect Clear.
Fonzie variation
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.
|
|
|
- Mechanical TSD
|
|
|
|
|
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 diagram).
Continuations
- T-Spin Double
Using a Donation technique may be feasible if O is late.
|
|
- LST Stacking
|
|
|
|
|
- Double Triple Cannon: A DT Cannon followup. Theoretically may result in a Perfect Clear.
|
|
|
|
|
|
|
|
|
|
|
|
- Imperial Cross: The second diagram is preferred because one will have a chance to make a Perfect Clear (89.68%). 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.
|
|
|
Using the Blink SZ Prop technique may result in the same situation.
|
|
|
- Perfect Clear after 8 lines: Although there are other ways, this way is the easiest to memorize because it has three solutions (42.38%). If S comes first, then it is increased to 77.78%.
|
|
|
|
|
- Perfect Clear after 12 lines: If one gets SZO in the third bag, it would not be possible.
|
|
|
|
|
|
|
|
|
|
Dingle variation
This is the latest variant, discovered by Agent RO in April 2021. This one places the J piece after the T-Spin Double, on the valley where the T-Spin Double was.
|
|
Continuations
- 6-line Perfect Clear + T-Spin Double: Requires O preceding I.
|
|
|
|
- Perfect Clear after 8 lines: Some ways require placing the remaining piece on top of the T-Spin Double. One example (PC chance: 75.08 %):
|
|
|
|
- Perfect Clear after 12 lines
|
|
|
|
|
|
Sub-variation
Try this variation when the J piece also comes early in the first bag.
|
|
|
Continuations
- T-Spin Double: Both examples can be followed by a Perfect Clear (93.10% for the second example).
|
|
- LST Stacking
|
|
|
|
|
- Perfect Clear after 6 lines: The last two diagrams will work if O or T come early in the third bag.
|
|
|
|
|
- Perfect Clear after 6 lines + T-Spin Double
|
|
|
- Perfect Clear after 8 lines: The chance is 68.77%. See TKI 3 Perfect Clear for all 8 solutions.
|
|
|
|
One can continue with a T-Spin Double if they cannot make a Perfect Clear.
LST (J first) |
Donation |
- Perfect Clear after 12 lines: It may work as long as O is early in the third bag.
