Mind the Edge ! #7
(Published on 19. October 2026, 08:18 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.
Killer cages: Digits in a cage do not repeat and sum to the number in the cage’s top-left corner.
Mark edges: Only the outside edges of each killer cage are marked — blue = 0 mines, red = 1 mine, red with a × = 2 mines. Mark the remaining edges by 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 having the same 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:
Mind the Edge ! #0: 000VE7.
Mind the Edge ! #2: 000UZC.
Mind the Edge ! #3: 000V0U.
Mind the Edge ! #4: 000V33.
Mind the Edge ! #5: 000VES.
Mind the Edge ! #6: 000VF7.

Solution code: The mine counts on all horizontal edges of column 9, read top to bottom (10 numbers, each 0–2).

A good practice to combine minesweeper and killer cages, I love it!
