TKI 3 Perfect Clear


 * Return to: TKI 3 Opening

The TKI 3 Opener can be continued with a Perfect Clear after 8 total lines after the 2 T-Spin Doubles. In this page, the best patterns are shown, arranged by Perfect Clear rate. If applicable, a Perfect Clear after 6 total lines will also be accounted.

Basic Setups

 * Z → O and L → S (100% PC rate, 47 minimal solutions + ɑ): In this case, the player can make a Perfect Clear after 6 or 8 lines. In the case of 8 lines, place the I piece on the very left.


 * O → J and I → L (99.92% PC rate, 67 minimal solutions)


 * SL → IO (99.64% PC rate, 59 minimal solutions): Normally, the J piece would be around the O piece, and therefore get a 100% PC rate, but in this setup, there is a gap beneath the O piece instead since the J piece is placed on the very right.

Okey's Plank
This is an uncommon continuation from Okey_Dokey. In the second bag, there is a horizontal I piece placement in the second bag which clears a single line. That line clear can happen before or after the second T-Spin Double.

The playfield is pretty empty after the second bag, thus offers a good opportunity to downstack. Alternatively, a Perfect Clear can always be achieved in the third bag. This Perfect Clear is so easily achievable because the single line clear in the second bag leaves an odd number of cells empty in the row below (see Parity).

Fonzie variation



 * SL → I and Z → J (100% PC rate, 65 minimal solutions + α): In this case, one can make a Perfect Clear after 6 or 8 lines. If going for 8 lines, place the O piece on the very right.


 * L → S → I and J → O / SL → I → J + O (100% PC rate, 61 minimal solutions)


 * Z → IL and O → J (99.96% PC rate, 78 minimal solutions)


 * S → O → J (97.74% PC rate, 10 minimal solutions)


 * SL → IZ and J → O / Z → O → J and I → L (96.79% PC rate, 30 minimal solutions)

Flat Top variation



 * O → L (J on hold, 100% PC rate, 59 minimal solutions + α): The most ideal way to get a Perfect Clear after 6 or 8 lines.


 * J → O (L on hold, 99.96% PC rate, 43 minimal solutions + α): The second-best way. If you want a Perfect Clear after 6 lines, keep the L piece on hold.


 * L → I (J on hold, 99.09% PC rate, 42 minimal solutions)


 * J → O (S on hold, 98.10% PC rate, 49 minimal solutions + α): This has the same piece dependencies as the second-best way, except that the L piece is used instead of the S piece.


 * O → S and T → I (98.06% PC rate, 24 minimal solutions): In the second bag, the J piece can be spun in even after the L piece is placed. After the T-Spin Double, place the I piece on the very right.


 * J → O → L (93.57% PC rate, 21 minimal solutions): If the S piece comes first, the rate will be 99.17%.


 * O → L → J (90.36% PC rate, 9 minimal solutions): If the J piece comes first, the rate will be 98.61%.


 * J → I and O → S (82.46% PC rate, 8 solutions): The J piece can be spun in after the L piece is placed.


 * O → J (41.27% PC rate, 3 solutions): This way is easy to memorize because of the small number of solutions.
