Minesweeper Strategy and Tips
Winning more Minesweeper games comes down to two habits: solve in the right order, and only trust what you’ve proved. The rules take a minute to learn. This page covers the rest. The mines would prefer you skip it.
Solve in the right order
- Certain mines. A number that touches exactly as many unopened tiles as its value: all of them are mines.
- Certain safe tiles. A number with all its mines found: every other tile around it is safe.
- Patterns. When no single number is enough, read neighboring numbers together (1-2, 1-2-1, 1-2-2-1), after subtracting flags. See the patterns guide.
- The mine counter. Late in the game, the number of mines left can rule tiles in or out.
- Only then, guess. And pick the guess carefully.
The habit that matters most: go back to step 1 after every tile you open. Each new number changes what its neighbors can tell you.
Yes, every tile. Minesweeper rewards the patient and the slightly obsessive.
Where to click first
In Classic mode on RetroSweep, your first click and the eight tiles around it are always mine-free. So your first click always opens an area.
A click away from the edges clears at least nine tiles. A corner click clears at least four. So start in the middle.
Some other versions, including the original Windows game, only make the clicked tile itself safe. There, corners are more likely to open an area, because a corner tile has only three neighbors that all need to be mine-free. The area just tends to be smaller.
On a daily board, start on the tile marked START HERE. It’s free. We checked.
Work the edge, one area at a time
All the information on a board sits on the border between opened and unopened tiles. Work along that border in one direction. Finish an area before jumping to the other side of the board.
Jumping around means re-reading the same numbers. It’s also how tiles get missed.
Flag with a purpose
You don’t need flags to win. They’re useful in two cases.
One: to chord, which means clicking a satisfied number to open all its neighbors at once. Two: to remember a mine you’ve already worked out, so you don’t work it out twice.
A flag placed on a hunch is dangerous, because your later deductions will trust it. If you’re not sure, leave the tile alone. A wrong flag is a tiny lie you tell your future self.
Right-clicking a flag turns it into a question mark. It does nothing to the game. Some players use it as a note for a tile they suspect but haven’t proved.
Use the mine counter
The counter in the top-left shows the number of mines minus the flags you’ve placed. When only a few tiles are left, it can decide the ending.
Say the counter shows 1 and one group of tiles must hold a mine. Then every tile outside that group is safe.
If the count ever comes out impossible, one of your flags is wrong. The counter doesn’t lie. Flags sometimes do.
When you have to guess, guess well
Random boards sometimes leave no safe move. Before you guess, check once more for a pattern you missed or a number you haven’t reduced. If it really is a guess:
- Compare the odds. A tile far from any number is about as risky as the board’s remaining mine density. A tile next to a 1 that touches three unopened tiles is about one in three. Take the lower risk.
- Pick the guess that tells you the most. A tile that could open a new area, or reach an unsolved region from a new side, beats one that only settles itself.
- Guess early. If a spot will need a guess anyway, take it before you clear the rest. That way you lose less time if it goes wrong. The exception is a spot the mine counter might settle later. Leave that one for the end.
If the guess goes wrong, don’t worry. We have a whole collection of things to say about it. The guessing guide goes into more detail.
Mistakes that cost games
- Misreading a number. Count all eight neighbors, diagonals included, every time.
- Chording on a wrong flag. Chording trusts your flags completely. One wrong flag and the chord opens a mine.
- Rushing the easy part. Most losses come from a quick click on a tile that wasn’t solved yet. Hard positions are rarely the problem.
- Forgetting the counter. In the last few tiles, the mine count often settles what the numbers can’t.
Moving up a difficulty
Mines get denser as you go up. About 12% of tiles are mines on Beginner, 16% on Intermediate and 21% on Expert.
Denser boards have more big numbers and smaller openings. You’ll need patterns more often than single numbers.
When you can clear one level most of the time, move up. The daily challenge is good practice at every level, because daily boards never need a guess.
