Inquisitive Indexer Snake
(Published on 7. September 2026, 12:47 by starwarigami)
The Sudoku Variant museum has reopened after extensive remodelling, and an Inquisitive Indexer Snake is the first to come and check out the new exhibits.
It enters the museum through one of the 4 exits (Corners) and wants to visit every exhibit (Box) exactly once, finishing at the centre of the museum (R5C5).
The snake consists of a single path of orthogonally connected cells that never touches itself orthogonally (diagonally is fine).
The Nth digit the snake passes through within a box gives the position of the digit N along its path within the box (e.g. if the 2nd digit the snake passes through in a box is a 5, then the 5th digit it passes through in the box must be a 2).
Solve the sudoku such that there exists a unique path for the snake through the museum.
All standard variant rules apply.

I was just startled for a while but after I had seen the break-in it went smoothly. Truly brilliant

I genuinely was convinced after looking at this that I JUST. WASN'T. SMART ENOUGH.
But you built it in such a kind, fun way that I made it through! Thanks for making me feel smart, friend. Beautiful work!

Easier than expected after reading the rules. I don’t know how you people think of these things.

For exhibit 7, should the rule say "greater than"?
