Mind the Edge ! 4x4 #2
(Published on 22. September 2026, 10:33 by Todd)
This is a hybrid of Sudoku and Minesweeper. You need both Sudoku rules and the fact that adjacent digits share the mine count on their common edge.
Sudoku: each row, column, and 2×2 box contains each of 1–4 exactly once.
Minesweeper: Each digit equals the total number of mines on that cell's four edges (top, bottom, left, right). Each edge holds 0 or 1 mine.
Pre-painted edges around given clues:
• blue = 0 mines
• red = 1 mine
Unpainted edges are not given — deduce and mark them. (Pen tool under Settings ⚙).
