- Return to: C-Spin
The C-Spin Opener can be continued with a Perfect Clear after 8 total lines (3 bags, 20 pieces) after a T-Spin Triple in the second bag, and sometimes a T-Spin Single or Double in the third. The most ideal openers to stack are the ones with a vertical T piece.
Because there are many ways to stack the second bag, it is recommended that you use only a few stacks because it is inefficient to memorize everything.
TOJ Core (TKI Signature)
For the TKI Signature C-Spin, the first bag can be stacked in 2 ways, mainly depending on the placement of the S and J pieces. The latter has the most continuations, so it is therefore the most unstable.
|
|
TOJ Core (S placement 1)
Regular setups
- Setup A - O → ZL (50% setup rate, 95% PC rate, 23 minimal solutions): The most ideal way for a chance of getting a Perfect Clear. There is a good chance the player can do a T-Spin Double before the Perfect Clear, and if the O piece comes first, the chance of achieving a Perfect Clear would be 99.17%.
|
|
|
|
|
- Setup B - L → I (66.67% setup rate, 94.09% PC rate, 23 minimal solutions): Note that if the first bag's J piece was used as the notch, there would be one more requirement, namely J before O.
|
|
|
|
|
- Setup C - L → I (66.67% setup rate, 93.06% PC rate, 12 minimal solutions): No matter if the first bag's J piece was used as the notch or overhang, this alternative to setup B can be utilized instead, as long as the L piece comes before the I piece.
|
|
|
|
|
Bonus setups
- Bonus setup A - L → I (23.81% setup rate, 97.50% PC rate, 35 minimal solutions): This setup has the highest Perfect Clear rate achievable from the TKI Signature C-Spin, but you also must keep the O piece on hold. However, it may send at least 15 lines if you can score a T-Spin Double before the Perfect Clear (not necessarily in a combo). If you must place the O piece before the T-Spin Triple, use Perfect Clear setup B or C.
|
|
|
|
|
- Bonus setup B - S → I, L → O (20.63% setup rate, 76.53% PC rate, 16 minimal solutions): This is the only way to stack the second bag in a way that results in the slimmest chance of getting a Perfect Clear after 6 lines, which stands at 2.38% (one solution). Otherwise, achieve one after 8 lines.

6 lines PC (2.38%) |
8 lines PC (76.53%) |
8 lines PC |
TOJ Core 2
- Z → S → I or OS → Z → I (L on hold, 100% PC rate, 77 minimal solutions): The most ideal way to stack the second bag, and you will always be able to achieve a Perfect Clear.
|
|
|
|
|
|
If you must place the L piece, you can place it either vertically (95.00% success rate) or horizontally (89.25%). In the case of the former, the solutions are the same as the final setup listed in TOJ Core 1.

89.25% |
- Z → L → S + I (O on hold, 99.44% PC rate, 40 minimal solutions)
|
|
|
|
|
|
If you must place the O piece, it is best if you can place it on the very right, as this will give you a 97.22% success rate. Otherwise, the O piece can also be placed on the cavity (93.02%) or overhang (88.02%).

93.02% |
88.02% |
- Z → OI → S or Z → OS → I → L or OS → Z → I → L (99.68% PC rate, 14 minimal solutions): This is the most ideal way to stack the entire second bag.
|
|
|
|
|
|
TZJ Core
In the first bag, if the I piece comes early, the TZJ Core C-Spin can always be stacked. However, since the TKI 3 Opening is more appropriate if you get an early I, this opener is not as popular as other C-Spin setups. The J piece is on hold as it will be used in different places, but it is advisable if you can place it on the L piece.
|
|
- S → L (Z on hold, 97.98% PC rate, 53 minimal solutions): The most ideal way to stack the second bag for a high chance of achieving a Perfect Clear. It will also send at least 15 lines if you can score a T-Spin Double before the Perfect Clear (not necessarily in a combo).

If you must place the O piece, it is ideal if you can place it on the overhang, as this will give you a 95.79% success rate. Otherwise, place it in the shallow hole (89.25%).

If you must place the Z piece, place it horizontally, and you will get a 96.90% success rate. Otherwise, place it vertically, and get an 80% success rate instead. In the case of the former, the S piece can be placed with an S-Spin if the L, O and Z pieces are placed already.
96.90% |
80.00% |
- S → Z (O on hold, 96.07% PC rate, 46 minimal solutions):

If you must place the O piece, place it on the overhang. This will give you a 91.03% success rate. Alternatively, place it on SZ (89.33%). It is not recommended to place it on the cavity because this will give you quite a low chance of making a Perfect Clear (41.90%), so it not shown.

- ZO → L → S (93.02% PC rate, 10 minimal solutions)
|
|

|
|
|
- I → L (88.02% PC rate, 11 minimal solutions): This stack has the least piece dependencies (I → L).
|
|
|
|
|
|
- O → ZL (85.28% PC rate, 7 minimal solutions)
