How do I flag tiles on mobile?

Toggle Flag Mode and tap a covered cell to place or remove a flag. On desktop you can also right-click to flag.

Is there first-click safety?

Yes. Mines are placed after your first reveal to ensure your first click is never a mine.

Is this version private?

Completely. The game runs fully in your browser and does not upload any data. Settings are stored locally only.

Minesweeper — Calm, Mobile, Privacy-First

Minesweeper — Simple. Gentle. Private.

Choose a cell to begin. Your first click is always safe.

Everything runs locally in your browser — no uploads, no accounts.

How to Play

Reveal empty cells to uncover numbers. Numbers show how many mines touch that cell.
Flag suspected mines. Clear all non-mine cells to win.
Mobile: Toggle Flag Mode to place/remove flags with a tap.
Desktop: Left-click to reveal, right-click to flag. First click is always safe.

Tips

Start from edges or large empty areas; zeros fan out and reveal quickly.
Use simple constraints: if a “1” touches only one covered cell, that cell is a mine.
Don’t guess if you can deduce — patience beats luck.

Best Strategies for Winning Minesweeper

Looking for a clear, non-stressful way to improve at Minesweeper? This guide collects the most reliable tips used by experienced players. It covers beginner habits, classic pattern recognition, and simple probability for the rare situations where logic alone cannot decide. Everything here applies to Beginner (9×9, 10 mines), Intermediate (16×16, 40 mines), and Expert (30×16, 99 mines).

1) Start wide, then tidy

Open a central cell first. With first-click safety, you’ll reveal a safe area. Large empty “0” zones cascade and give you lots of numbers to work with immediately.
Work the frontier. Focus on the boundary where revealed numbers touch covered cells. This is where information lives.

2) Learn the bread-and-butter patterns

These patterns appear constantly along straight edges:

1-1 (adjacent ones). If two “1” tiles share exactly two covered neighbors in a row, each “1” points to its outer neighbor. The middle shared cell is safe.
1-2-1. Along a straight line, the two outer covered cells are mines; the cell directly touching the “2” on the opposite side is safe. (This clears big strips quickly.)
2-3-2. A frequent variant where the three middle covered cells are mines; the diagonal extensions are often safe. Check the local shape before committing.
Corners and L-shapes. A “1” in a tight corner pointing to exactly one covered cell means that cell is a mine; the diagonally adjacent cell is usually safe.

When in doubt, redraw the neighborhood in your head as small groups. Minesweeper is local: most deductions use only the tiles within one or two steps.

3) Use flags deliberately

Flag only when it helps logic. If a number “2” already touches two obvious mines, the remaining neighbors are safe. Over-flagging slows you down and can cause mistakes.
Keep an eye on the mines left. The remaining-mine counter keeps your model honest and helps you spot contradictions early.

4) Clear with confidence (a.k.a. chording)

In many versions of Minesweeper, once a number has exactly the right count of flagged neighbors, you can reveal its remaining neighbors in one action (“chord”). If your version doesn’t support chording, you can still manually reveal those safe cells as a batch—same logic, one extra click.

5) Defuse common traps

Double-counting. Remember each number counts all eight neighbors. Check diagonals.
Edge mirages. Along the outer border, the board has fewer neighbors. Re-evaluate patterns; a 1-2-1 at the edge can behave differently than in the middle.
Islands. If you solve one area, zoom out. A single safe click somewhere else can unlock the hard spot you were staring at.

6) When logic runs out, use gentle probability

True “50/50” guesses are rare. Compare candidate tiles: the one adjacent to more unresolved numbers is usually riskier. If multiple guesses seem equal, choose the guess that, if safe, reveals the largest area (more information next turn).

7) Build calm habits

Click slowly near the endgame. Most losses happen after you’ve done the hard work.
Name the rule before you click. Saying “this 2 already has two mines” prevents impulsive errors.
Reset early, not angrily. A quick, relaxed reset beats a flustered streak of mistakes.

Minesweeper rewards steady logic over speed. Practice the core patterns (1-1, 1-2-1, 2-3-2), flag with intention, and let large safe areas unfold naturally. With these habits, wins become consistent—even on Expert.
