Mind the Edge ! #4
(Published on 23. September 2026, 10:53 by Todd)
Sudoku: Place digits 0–8 so that each digit appears exactly once in every row, column, and 3×3 box.
Edge mines: Each digit equals the total number of mines on that cell’s four edges (top, bottom, left, right). Each edge holds 0, 1, or 2 mines. Adjacent cells share the edge between them (with same mine count of that edge).
Given edges: Edges around the given digits are pre-marked:
• blue = 0 mines
• red = 1 mine
• red with a red × = 2 mines
All other edges are unmarked and must be deduced. Mark remaining edges yourself.(Pen tool under Settings ⚙).

TIPS: 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. For example, an 8 forces 2 mines on each of its four edges, so none of its four neighbors can be 0 or 1. Likewise, none of the four neighbors of a 0 can be 7 or 8.The figure below shows one possible arrangement of digits in a box, together with mines on edges:

Solution code: The mine counts on all vertical edges of row 9, read left to right (10 numbers, each 0–2).

It's indeed a bit harder than before, requiring a basic understanding of some relationships or patterns.
