Minesweeper Rules
- Left-click a cell to reveal it. If it's a mine, you lose. If it's safe, it shows a number.
- Numbers indicate how many mines touch that cell (including diagonals). A "3" means 3 mines are adjacent.
- Right-click a cell to flag it as a suspected mine. Right-click again to remove the flag.
- Clear all non-mine cells to win the game. You don't need to flag every mine — just reveal all safe cells.
- Chord clicking: When a number has exactly that many flagged neighbors, double-click it to reveal all other adjacent cells at once.
- First click is always safe. The cell you click first — plus its neighbors — will never contain a mine, in Daily and Practice modes alike.
Minesweeper Strategy — How to Win
- Start in a corner. Clicking a corner cell gives you the most information with the fewest adjacent cells to worry about. It often reveals a large area.
- Learn the 1-2-1 pattern. If you see 1-2-1 in a row, the cells below the 2 are always mines, and the cells below the outer 1s are always safe. This is the most powerful pattern in Minesweeper.
- Use the 1-1 pattern. When two 1s are adjacent and share a common unflagged cell, the cell beyond the second 1 is always safe.
- Flag known mines. Once you deduce a mine's location, flag it immediately. This prevents accidental clicks and helps with chord clicking.
- Count remaining mines. The mine counter tells you how many mines are left. If the counter matches the number of flagged cells, all remaining unflagged cells are safe.
- Work systematically. Don't click randomly. Scan the board row by row, looking for cells where the number matches the count of hidden neighbors — those hidden cells are all mines.
- Use probability when stuck. If you can't deduce a mine's location, calculate which cell has the lowest probability of being a mine. Beginner boards are usually solvable without guessing.
Minesweeper Difficulty Levels
- Beginner: 9×9 grid with 10 mines (12.3% density) — perfect for learning the rules and basic patterns.
- Intermediate: 16×16 grid with 40 mines (15.6% density) — requires more advanced strategies and pattern recognition.
- Expert: 16×30 grid with 99 mines (20.6% density) — the ultimate challenge. Even experts need to guess sometimes.
Common Minesweeper Mistakes
- Clicking randomly. Minesweeper is a logic game, not a guessing game. Every move should be based on information from revealed numbers.
- Not using flags. Flagging known mines prevents accidental clicks and enables chord clicking.
- Ignoring the mine counter. The counter tells you how many mines remain — use it to verify your flags and find safe cells.
- Playing too fast. Rushing leads to mistakes. Take your time to analyze each number carefully.
