Japanese Minesweeper (Expert)
(Eingestellt am 4. April 2026, 00:00 Uhr von cyddrdrd)

Hi Minehunter,
Minesweeper is back! Your goal is to find all the hidden mines in the grid. This time, however, all clues are given as Japanese sums outside the grid, so no numbers inside the cells are given!
Just like classic Minesweeper, I prepared three levels for you:
Finally, here you are, the
Expert. While this is the largest one, don't be intimidated. You've already made it through the
Intermediate, haven't you? Bring your calculator and have fun!
Oh, what's that? You are too lazy to use it? Then come a little closer… I'll whisper a secret: the sum of all column clues is 776 + ??.
Rules
- Classic Minesweeper: There are some mines in the grid. Every clued cell (i.e., a non-mine cell that is orthogonally or diagonally adjacent to at least one mine) contains a digit equal to the number of adjacent mines. Cells not adjacent to any mine are left empty.
- Japanese Sums: Clues outside the grid represent the sum of digits in each contiguous sequence of clued cells, in the order of appearance from left to right or top to bottom. Consecutive sequences must be separated by at least one mine cell or one empty cell.
A '?' represents any digit from 0 to 9. For a double-digit number, its first digit cannot be 0.
Thank you
MonsieurTRISTE for testing and suggestions!

This experience is best described as "just because you can doesn't mean you should" haha! But the break-in and the ending made it worth the headache
