My Friend In The Mirror
Ok I know I said two times I was going to add borders to my puzzles, but this is a collab puzzle and we were fine with it as is. And that's ok.
Anyway, hello mates. This was a collab I did with Scojo for his own setting saturday series, this is a slightly older prompt where we had to do something cool with mirrors or reflection
Rules:
- Normal sudoku rules apply.
- Friendliness Mirror: A cell is considered friendly if its digit matches at least one of the following: its row number, column number or box number. Any pair of cells reflected along the marked diagonal have the same friendliness value (they are either both friendly or not both friendly)
- Index Lines: On a blue line, the digit in the Nth cell along the line (starting from the diamond) indicates the position on the line where the digit N appears
- Entropic lines - Any set of three sequential cells along a tan line must contain a low digit (123), a middle digit (456) and a high digit (789). Digits may repeat on lines, if allowed by other rules.

The friendly mirror was a bit strange to get used to, but once I understood the implications this flowed very nicely.

Very nice spin on the "parity mirror" rule.
