How to Play
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
Minesweeper is a deduction game played on a grid of covered squares. Reveal a safe square and its number tells you how many mines are in the up to eight squares touching it, including diagonals. A blank means no neighboring mines and expands into a larger safe area. The aim is to reveal every non-mine square; correctly flagging every mine is not required to win.
Choose Beginner (9 × 9 with 10 mines), Intermediate (16 × 16 with 40), Expert (16 × 30 with 99), or a custom board. The first revealed square and its surrounding one-cell area are protected from mines. Mines are placed randomly elsewhere after that first click, so the opening protection does not guarantee that every later position can be solved without a guess.
A flag records your own deduction. The remaining-mine counter subtracts the number of flags from the board total; it does not assess whether the marked squares are actually mines. A reliable basic rule is: when a revealed number has exactly that many covered neighbors, all those neighbors are mines; when the number already has that many flagged neighbors, the other covered neighbors are safe.
On a revealed nonzero number, a double click attempts to open adjacent unflagged squares when the number of adjacent flags matches the clue. It checks only the flag count, not whether the flags are correct. An incorrect flag can therefore make this shortcut reveal a mine.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Start with a preset or set custom rows, columns and mine count. Custom dimensions must each be between 5 and 24; mine count must be at least 1 and no more than the number of cells minus 9.
Click or tap a covered square to start. Use the displayed count to compare neighboring covered squares with flags. Right-click or press F to toggle a flag; on a touch screen, press and hold a square.
Double-click a revealed nonzero number to try opening its other neighbors after the adjacent flag count equals that number. Check your flags first: the shortcut cannot tell a correct flag from a mistaken one.
Reveal every safe square to win. Use the reset control to begin again; changing board settings also resets the game and timer.
The timer starts at the first reveal. Use flags as a working map and revisit uncertain areas whenever a new number provides additional constraints.
Use cases
See how the tool fits into real work and everyday tasks.
A new player can begin on Beginner and practice comparing one number with its immediate neighbors. Focus on deductions that establish mines or safe squares before making another reveal.
On a phone or computer, choose a preset board and use taps, clicks or flags to progress. A reset starts a fresh layout when you want another round.
Adjust the board dimensions and mine count within the allowed range to create a different density. Record the settings alongside a time if you want to compare your own attempts.
Q&A
Find concise answers to common questions and confusing cases.
It means exactly two of the square’s up to eight adjacent neighbors contain mines. It does not show the total number of mines remaining on the entire board.
Yes. The first clicked square and its surrounding one-cell area are excluded when mines are placed. Later clicks are not protected.
No. Revealing every square without a mine satisfies the win condition; flags are optional markers to help you reason.
No. The remaining mines are placed randomly outside the protected opening, and the game does not guarantee that every resulting board can be solved with deduction alone.
Notes
Review scope, result limitations, and important precautions before use.
Mine locations are random after the protected first move, so the game does not promise a no-guess board. A flag is your annotation rather than a verified mine location, and the remaining count can be wrong when a flag is misplaced. The best time is kept only for the current page session; it is not a saved cross-session record. Changing board settings clears the current board and timer.
