About Nonosweeper
What is Nonosweeper?
Nonosweeper is a hybrid puzzle that fuses two beloved puzzle formats: the mine-clearing tension of Minesweeper and the grid-deduction logic of a Nonogram (also known as Picross or Griddler). Unlike standard Minesweeper, you never click blindly to reveal numbers — instead, the full set of row and column clues is visible from the very start, just as in a nonogram. Your job is to use those clues to work out exactly which cells hide mines, then click the safe cells to reveal them.
The Minesweeper element keeps the stakes high: one wrong click on a mine and the puzzle ends immediately. There is no safe first click and no random guessing allowed — every move must be deduced from the clues.
How to read the clues
Each row and column has a clue made up of one or more numbers. Each number represents a consecutive run of mines in that row or column. The runs appear in order (left-to-right for rows, top-to-bottom for columns) and are separated by at least one safe cell.
For example, a row clue of 3 1 2 means: three mines in a row, a gap, one mine, a gap, then two mines in a row. A clue of — means no mines at all in that row or column.
Strategy tips
- Start with zero-clue rows/columns. A "—" clue means every cell in that line is safe — reveal them all for free.
- Use overlap analysis. If a run is large enough that it must overlap itself in every valid placement, those overlapping cells are definitely mines.
- Cross-reference rows and columns. A cell's row clue and column clue together often narrow down its state completely.
- Flag mines before revealing. Once you are certain a cell is a mine, flag it before clicking adjacent safe cells — it keeps the mine counter accurate and the board readable.
Difficulty levels
- Beginner (8×8, 16 mines): A compact grid with short clues. Good for learning the mechanic.
- Intermediate (10×10, 35 mines): More cells and denser runs require careful cross-referencing.
- Expert (15×15, 75 mines): A large grid with complex multi-run clues — a serious nonogram challenge.
