Minesweeper walkthrough: prove a mine, then open safe cells

A revealed number counts mines in the eight surrounding cells, including diagonals. Follow this real 8×8 board to identify one mine and safely open two neighbors using only the clues you can see.

Tap or left-click a hidden cell to reveal it. In the default controls, hold for 0.6 seconds on mobile or right-click on desktop to toggle a flag. Tap a revealed number to open its remaining hidden neighbors when the adjacent flags and already-revealed mines together match the clue. Only do this after proving the flags are correct.

Rows run top to bottom and columns left to right, starting at 1. Dark cells are hidden, pale cells are revealed, F marks a flag, and gold outlines show the cells being discussed. Hidden mine locations and numbers are never shown.

1 · Find a forced mine

The top-left opening has revealed a clear area and its boundary numbers. Look at the gold-outlined 1 at row 2, column 2. Seven of its eight neighbors are already revealed and safe. Its only hidden neighbor is row 3, column 3, so that cell must contain the one mine.

2 · Flag the proven mine

Place a flag at row 3, column 3. The flag records the deduction; placing it does not reveal the cell or prove anything by itself. Here the number and its seven revealed neighbors are the proof.

3 · Use a second clue

Now look at the 1 at row 2, column 4. The proven mine at row 3, column 3 already accounts for that clue's entire mine count. Its two remaining hidden neighbors, row 3, columns 4 and 5, must therefore be safe. The gold outlines mark the clue and these two safe cells.

4 · Open the safe neighbors

Tap the revealed 1 at row 2, column 4 to open its remaining neighbors together, or reveal the two safe cells individually. Row 3, column 4 shows 3; row 3, column 5 shows 1. You have revealed two more safe cells without losing a life. Use these new clues for the next deduction.

A matching flag count is not proof

1. When a clue's hidden neighbors are exactly the mines it still needs, those neighbors are mines. Count diagonals too.
2. Once proven adjacent mines account for the full clue, its other hidden neighbors are safe.
3. A misplaced flag can make a number look satisfied. Opening the remaining neighbors can then hit a mine. Arcadity gives you three lives, but the deduction still needs to be correct.

Minesweeper scoring: progress, time, and lives

Cell points are 20 for each revealed safe cell, plus up to 1,000 progress points. The progress bonus is 1,000 × (revealed safe cells ÷ all safe cells)², rounded down. Flags alone earn nothing. In this example, revealing 14 of 54 safe cells gives 347 cell points; revealing 16 gives 407.

The final score multiplies cell points by 1 + (seconds remaining ÷ round time limit), then by an accuracy factor of 1.00, 0.85, 0.70, or 0.55 for zero, one, two, or three mine hits. That product rounds down; revealing all safe cells then adds 500 points. The third mine hit or an expired timer ends the round. The example's cell points are not a final match score.
