Triple Triple PC is a opener invented by Yu. It is an opener that allows you to get a Perfect Clear after a T-Spin Triple.
Build Order
First Bag
In the first bag, the L and Z pieces need to come early.
Please remember the mirrored shape as well. S and J comes early.
Second Bag
In the second bag, you can always make a T-Spin Triple in one of the following two methods. If possible, build the first, as it can result in a Perfect Clear after 8 lines.
J before O or J before T
In the case of JO before Z before L, you do not need to wait for gravity; the Z can be spun in with Soft Drop —> Rotate CW —> Rotate CW —> DAS Right.
TO before J
Alternate 2nd Bag Setup
Created by 10Penta. If you get a late J but still want to build an 8-height PC, then you can use this alternative setup (Requires Z before J):
You now have a 67.1% PC chance with 9 minimals.
Third Bag
In the first loading method, you can always get a Perfect Clear in the third bag. One solution can result in a T-Spin Triple beforehand. Some other solutions may result in a T-Spin Double or T-Spin Single beforehand.
Third Bag continuations
When you use the second loading method, you can use any of these continuations:
Perfect Clear after 10 lines
There is a 95% chance to stack your third bag like this, with the exception of TLO before S before Z. After the T-Spin, you will have a 50.4% chance to do a Perfect Clear.
Perfect Clear after 14 lines
Note that this one is a revised version by HDChung. For the past versions of 14L PCs, which might feel easier to some of you, refer to these past revisions: the original 14L PC 10Penta's 14L PC
The third is mostly possible to build (fails on L>S>J and O>J) without 180 spin. With 180 spin, this is always possible to build.
The fourth bag can always be stacked.
Note that you can delay the 1st T-spin double to build a fractal:
You now have a 100% chance of PC with 8 minimal solutions. Note that the first solution can be used 93.9% of the time with 180 spins and 83.5% of the time without 180.
These are the potential Tetris / T-Spin Double solutions, which are optional to learn.
The following 4th bag with some queue dependency is also optional to learn, but it will lead to higher chance of T-Spin Double solutions.
This will also have 100% 14L PC chance with the following 7 minimal solutions. Note that the first and third solutions have potential Tetris, the second solution has potential T-Spin Double, and the fourth one has both.
These are some, but not all, optional solutions with potential Tetris / T-Spin.
New TTPC
New TTPC is a variation of TTPC found by 10Penta that has a lower build rate than TTPC but guarantees the 8L PC setup if using 180 spins.
