[tetr.io] Cool 9 Line PC

Rest in peace former prime minister Shinzo Abe.

Used photoshop to make thumbnail for the first time so I don't spend the first 20 minutes of posting the video making adjustments to it.
Now both editing and thumbnail making is from adobe.

The point is that
Normal pc has 8 lines, which consist of 8×10=80 squares, and 80÷4(every piece has 4 squares)=20...0. The remainder is 0, so you can do a pc with 20 pieces.

In this case, you have nine lines, which is normally 90 squares, and 90÷4=22...2, so you can't do a 9 line pc yourself.
However two lines of it was garbage line, so you actually only have to fill 90-9*2=72 squares, and 72÷4=18...0, enabling you to do a pc with 18 pieces!

In conclusion, suppose that you have x lines in total and y lines are garbage
If (10x-9y)%4 = 0, then doing a pc is possible (but not always I guess)
And (x, y) = (9, 2) satisfies the equation.

Sorry for my poor English TAT

If garbage line is even, perfect clear is possible.

Your opponent really went early line clear into eat shit, huh?
I agree, that PC was very cool indeed, especially because the garbage lined up for it and you don't get to see that every day.

What pc would this even transition to? I assume some wonky 5th cause 2 pieces left in bag

Instead of counting the line you need to count the grid and its even and multiply by 4 then its possible to do a pc
