About Minesweeper
Minesweeper is a logic puzzle played on a field of hidden squares. Every number you uncover gives you information about the mines nearby. Piece those clues together and turn an uncertain field into a clear picture, one safe move at a time.
On Lolo, choose a small field for a quick puzzle or a larger challenge. No-guess fields, hints, undo, and a hands-on lesson let you choose how much guidance you want as you learn.
Your goal
Reveal every square that does not contain a mine. Revealing a mine ends the game. You do not need to flag every mine to win: the goal is to uncover all the safe squares.
Read the numbers
A revealed number counts the mines in the eight squares touching it, including diagonals. A 1 means exactly one neighboring square contains a mine; a 2 means exactly two. At the edge of the field there are fewer neighboring squares, but the rule is the same.
Revealing an empty square opens the connected empty area and its bordering number clues automatically.
Place flags
Put a flag on a square you believe contains a mine. Flags are reminders, not proof: placing one does not check your answer. Remove a flag when you change your mind.
The mine counter shows the total mines minus your flags. Reaching zero does not mean you have won or that every flag is correct.
Reveal around a number
When the number of neighboring flags matches a revealed number, you can reveal the remaining neighbors together. This is called chording. With “Tap revealed numbers” enabled in Settings, activate the number to do this. With a mouse, you can also press the left and right buttons together on it.
Controls
| Input | Action |
|---|---|
| Touch or pen | Tap a square using the selected Reveal or Flag tool. Hold a square to mark it. |
| Mouse | Click using the selected tool. Right-click to mark a square. |
| Keyboard | Tab to the board, then use arrow keys to move between squares. Enter or Space uses the selected tool; F marks the focused square. |
| Undo | Use the Undo button, or Ctrl+Z / Command+Z while the board has keyboard focus. |
| Board view | Drag to pan, pinch or use the mouse wheel to zoom. Reset View returns to the default view. |
The Reveal and Flag tools stay below the board. If Question marks is enabled, marking cycles through a flag, a question mark, and an unmarked square.
Choose a field
| Field | Dimensions | Mines |
|---|---|---|
| Small | 9 × 9 | 10 |
| Medium | 16 × 16 | 40 |
| Large | 30 × 16 | 99 |
“Allow guessing” in Settings applies to new fields. Leave it off for fields designed to be solved with logic. Turn it on if you want fields that may require a guess. Board themes change the appearance, not the rules.
The timer records elapsed play time. First concentrate on clearing the field; you can aim for a faster finish as you become more confident.
When you get stuck
Compare clues that share unopened neighbors. A flag deduced from one clue may make another clue useful. Use Hint for guidance or Undo to revisit a move.
