The 3rd Room
(Published on 24. September 2025, 18:13 by Wiggel)
This is the second puzzle in my '3 Series'.
Starting the creation of this puzzle, I knew that indexing digits can give way to some interesting and elegant logic chains. So I tried just indexing 3's and see where that gets me. I needed some other digits to actually make it work, but I managed to stick to multiples of 3 for those. Have fun solving.
Rules:
- Normal sudoku rules apply.
- Numbered rooms: clues outside the grid indicate the digit which has to be placed in the Nth cell in the corresponding direction, where N is the digit placed in the first cell in that direction.
Solution code: Column 2 (top to bottom)

Very simple solve if you’ve done indexing or numbered rooms before. Really interesting to see how much comes out of just placing 3s around the grid!
