4 x 4 x 4

Rules:
In each grid, normal 4x4 sudoku rules apply.
The grids are numbered 1-4 in normal reading order.
2x2 boxes within each grid are numbered 1-4 in normal reading order.
Cells within each 2x2 box are numbered 1-4 in normal reading order.
Reading along a coloured line (starting at the end with the invisible bulb), the digits WXYZ indicate that in grid W, box X, position Y, a digit Z should be placed.
Every line indexes a different cell, which always happens to be located somewhere on a line.

spent 90 minutes trying to read, spent maybe 5 minutes doing the actual puzzle once i actually started doing it
i foolishly assumed each line was self indexing as well as grid indexing, that is NOT what "each line indexes a different cell" means. idk how i came to that conclusion

I also missed that you have to find the invisible bulb...even after reading the comments! Very nice easy puzzle with a solve path that shows how intentional the setting is.
The rules made me realize how weird it is that as a mathematician, I think W should come after Z when using variables.

Wow that was pretty amazing - I thought I had messed up and re-read the instructions... invisible bulbs!

Once I learned how to read this was wonderful to solve

Really interesting puzzle—I'd say it didn't feel like doing sudoku at all, but some other kind of puzzle. Very satisfying
Marty: ahhh thankyou i'm glad you enjoyed it. And love 3blue1brown :)
By the way—I watched the 3blue1brown video about Hamming codes recently, and the patterns in this puzzle reminded me of it. A clearer head than mine might be able to make a stronger connection there!

Wow! That was really striking, and while not hard, not totally trivial either and made you think at each step.

This is impressive that it solves uniquely with just those rules. Another amazing puzzle.
