Japanese Minesweeper (Beginner)

(Eingestellt am 21. März 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:

⇒ Beginner (9x9, 10 mines)
⇒ Intermediate (16x16, 40 mines)
⇒ Expert (16x30, 99 mines)

Here is the Beginner. Don't be fooled by its name — it is much more challenging than a classic Beginner Minesweeper! Estimated difficulty is around 3–4*, so don't expect a quick solve. Have fun!

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 and Christounet for testing and suggestions!

Example puzzle (6x6, 5 mines):
It is highly recommended to try the example first to get familiar with the ruleset.

Lösungscode: Column indexes of all mines in reading order (left to right, top to bottom; 10 digits in total). For the example puzzle, it would be 16355.

the example puzzle was harder for me than the 9x9, but I guess that's testament to how well the example did at preparing me for the real thing. that said, I'm scared of the other difficulties

Super cool idea. Working up the courage to try the intermediate and expert modes soon

Terrific puzzle! It took quite some time for me to figure out how to think, and I think it's a ruleset with a fairly steep learning curve. Very fascinating!
