Mine Finder is a deduction puzzle where you clear a grid of hidden mines using numerical clues. Each revealed number tells you exactly how many mines are adjacent to that cell (including diagonals). By combining these clues, you can logically determine which cells are safe and which contain mines. Far from random clicking, every Mine Finder board is a rich exercise in constraint-based logical reasoning.
How to play Mine Finder
Reveal Cells
Click any cell to reveal it. If it contains a mine, you lose. If it's safe, it shows a number or opens a blank area.
Number Clues
Each number tells you how many of the 8 adjacent cells (including diagonals) contain mines. Use these clues to deduce mine locations.
Flag Mines
Right-click or long-press to flag cells you've determined contain mines. Flagging helps track your deductions visually.
Blank Cascades
When you reveal a cell with zero adjacent mines, all neighboring safe cells automatically reveal, often opening large sections of the board.
Count Carefully
Each number accounts for ALL adjacent mines, including ones you've already flagged. Subtract known mines to find remaining threats.
Win Condition
Win by revealing every safe cell on the board. You don't need to flag all mines - just avoid clicking on any of them.
Strategy & solving tips
Expert Mine Finder players use systematic deduction patterns rather than guessing. Learning these core techniques transforms the game from luck-based to logic-based.
- The "1-1" pattern: when two adjacent 1s share exactly two unrevealed cells, the mine must be in the cell unique to one of them
- Satisfied numbers: if a number already has that many adjacent flags, all remaining adjacent cells are safe - reveal them
- Unsatisfied numbers: if the remaining unrevealed cells around a number equal its value minus existing flags, all remaining cells are mines
- Work the borders between revealed numbers and unrevealed territory - that's where deductions happen
- Use "effective number" counting: subtract adjacent flags from each number to track remaining mines more easily
- Start from corners and edges where cells have fewer neighbors, making deductions simpler
History & origins
Hidden-mine number games date back to the mainframe era of the 1960s and became a worldwide habit on home and office computers in the early 1990s. The logic puzzle version, where every mine is deducible without guessing, grew up separately in puzzle magazines and competitions, and no-guess mine puzzles have appeared at the World Puzzle Championship since the 1990s.
Mine Finder FAQ
Is Mine Finder always solvable without guessing?
Yes. Randomly generated mine boards can leave you with a coin-flip guess, but every Mine Finder board is checked so that every mine can be logically deduced without needing to guess.
What does the number in a cell mean?
The number tells you exactly how many of the 8 cells touching it (horizontally, vertically, and diagonally) contain mines. A "1" means one adjacent mine, a "3" means three, and so on.
What's the best first move?
Corners or edges are statistically safest for a first click since they have fewer adjacent cells. Many implementations guarantee the first click is always safe.
How do I get faster at Mine Finder?
Practice pattern recognition. Common patterns like 1-2-1 and 1-1 along edges become instantly recognizable with experience. Focus on accuracy first - speed follows naturally.
