Minesweeper is the classic single-player logic puzzle where careful deduction beats quick reflexes. While platforming titles like Cat Mario test your patience through sudden hazards and precise jumps, Minesweeper presents a quiet grid where every single obstacle obeys strict mathematical rules. There are no surprise ambushes or moving targets; clearing the board relies entirely on reading numerical clues and methodically isolating safe ground.
A round begins with a blank field of covered squares. Uncovering a safe cell reveals either an opening that clears neighboring empty spaces or a number indicating how many mines touch that specific tile across all eight adjacent directions. By cross-referencing adjacent numbers, you can determine exactly where explosives lie, place protective flags, and safely clear the rest of the board.
How to play
The core controls and mechanics are straightforward to pick up:
- Left-click or tap: Uncover a covered square. Landing on a hidden mine triggers an explosion and ends the round immediately.
- Right-click or long-press: Mark a suspicious square with a flag to avoid accidentally clicking it later.
- Chording: Clicking an already opened number whose neighboring flags match its number will quickly clear all remaining adjacent unflagged squares.
Your objective is to reveal all safe tiles across the entire board without detonating a single mine. Numerical hints range from 1 to 8, representing the exact count of dangerous neighbor squares.
Core strategies and tips
Approaching each board methodically will dramatically improve your clearing speed and consistency:
- Master basic edge patterns: Learn classic combinations such as 1-2-1 and 1-2-2-1 along flat borders. A 1-2-1 configuration along a straight wall always means mines sit adjacent to the ones, leaving the center tile safe.
- Work inward from corners: Focus on corners and outer edges where tiles have fewer neighbors. Clearing these restricted spots creates anchor points that make central numbers much easier to resolve.
- Flag only when certain: Never guess when placing flags. A single incorrect flag creates false assumptions that can derail your calculations across the entire quadrant.
- Resolve forced 50-50 guesses early: If an isolated corner presents an unavoidable coin flip with no remaining logical clues, take the guess right away instead of wasting minutes solving the rest of the board first.

How do you flag a suspected mine on mobile or touchscreens?
On touch devices, long-press or tap the dedicated flag toggle icon before tapping the square to mark it safely.
Is the first click in Minesweeper always safe?
Yes, standard Minesweeper boards ensure that your opening click never lands on an explosive mine, usually opening an empty cluster.
