Still at it. It occurred to me that the hearts on the left take 19 blocks to form.
Coincidentally, 19 is the total number of unique rotations of all the Tetris pieces, summed accordingly:
T – 4
S + Z – 2 each
J + L – 4 each
I – 2
O – 1
I wonder if there’s a solution that uses each rotation once AND avoids piece adjacency?
This sounds like a problem you should solve by writing a program to search for arrangements that work.
Yep, as soon as the question came to mind I thought the same thing. Haven’t really been feeling the programming groove in my spare time lately but I might just have to give it a crack to sate my curiosity.
I have been trying all morning and I haven’t got remotely close. It doesn’t feel doable, but for the life of me I can’t tell you why. Tetrominos have interesting properties.
