Mind the Edge ! #6
(Published on 10. October 2026, 11:20 by Todd)
Sudoku: Sudoku with digits 0–8 on each of FIVE 9×9 boards arranged in a plus (center + north/south/west/east). Four corner boards are unused. Within each board, every row, column, and 3×3 box contains each of 0–8 exactly once.
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.
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 ⚙).
Large board (desktop recommended): Settings → Experimental → “Test Large Puzzle UI”. Zoom with mouse wheel / trackpad; right-click and drag to pan. Mobile zoom is not supported.

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:
Mind the Edge ! #0: 000VE7.
Mind the Edge ! #1: 000UYM.
Mind the Edge ! #2: 000UZC.
Mind the Edge ! #3: 000V0U.
Mind the Edge ! #4: 000V33.
Mind the Edge ! #5: 000VES.

Solution code: Enter the digits from column 9 of the EAST board (top to bottom).
