How to play Minesweeper
The 850305 guide to Minesweeper starts with observe, then act. Your task is to open all 71 safe cells. Opening a mine ends the round. Flags help you mark suspected mines but do not replace opening safe cells. The controls and example below describe this exact implementation.
Observe, then act
Look at the full play area and read the status message. Make a deliberate choice and compare the outcome with your expectation.
Your goal
Open all 71 safe cells. Opening a mine ends the round. Flags help you mark suspected mines but do not replace opening safe cells.
Step by step
- Open a covered square to reveal it.
- A number counts mines in the surrounding eight positions.
- Right-click to flag on a computer, or enable Flag mode on a phone.
- Use safe deductions to open the remaining cells.
Controls
Click/tap to open. Right-click to flag, or use the Flag mode toggle for touch devices.
A useful example
A revealed 1 with only one covered neighbour means that neighbour contains a mine.
Watch out for this
A flag is your own note, not a confirmation from the game. Remove a mistaken flag before opening that square.
