Norma's Shadow (Infections)

(Published on 13. September 2026, 19:28 by gdc)

Episode 4 of the Norma L. Dokes series. It uses walls which limit both path movement and infection spread. There is also "akari stlye" dynamic fog where the reveals mimic the vision inside a maze. According to testers (thanks everyone!) it should be 3.5-4 stars. I hope you enjoy!

Rules
Norma L Dokes: Normal sudoku rules apply.
Darkness covers all clues. Placing a correct digit lights up its row and column up to the first seen walls.
Neighbors: Two cells are neighbors if they share an edge which is not a wall.
Infection Sites: Each digit matching its box number is an "infection site". Each row and column contains an infection site. They are infected.
Infections: Infected cells infect every smaller neighbor. Infections keep spreading until no infected cell has a smaller uninfected neighbor. (Every infected cell can be traced back to one or more infection sites).
Path: Draw a path connecting the two arrows such that adjacent cells along the path are always neighbors and no infected cells are visited.
Microscopes are uninfected and count the number of infections in the (3, 5 or 8) surrounding cells.
Kropki Tabs join consecutive digits.
