Muffuletta (Fog, Modular Lines, Sandwich Layers)
(Published on 18. August 2026, 17:00 by Crusader175)
Been wanting to make more puzzles with this ruleset, and finally got around to making one. Hope you enjoy solving the puzzle!
Rules:
Normal sudoku rules apply.
Dynamic Fog: Placing a correct digit clears fog from its cell and possibly other cells.
Modular Lines: Any set of three sequential cells along a teal line must contain one digit from [1,4,7], one digit from [2,5,8] and one digit from [3,6,9].
Sandwich Layers: The number in the top left corner of a cage indicates the sum of the digits sandwiched between 1 and 9 in that row (red cage) or in that column (blue cage), where a "🥪" can represent any sum ranging from 0 to 35. The digit in a cage indicates how many digits (including the crusts of 1 and 9) the corresponding sandwich sum contains.

Lovely puzzle. Great interactions between the sandwich sums and the modular lines under the fog

Very nice! Great and clever break-in which was a bit tricky, smooth afterwards. Thanks

Nice idea, as someone who has been to Central Grocery: How did you came up with the name?

Very nice but I found it hard. Maybe 4 stars difficulty?
