How to Play and Win Minesweeper Without Guessing

By Haroon Mustafa · Updated October 2026 · 12 min read

Minesweeper looks like a game of luck, but most of a board can be solved with pure logic. If you learn to read the numbers as exact rules and spot a handful of common patterns, you will rarely need to guess. This guide walks you through it step by step, from your first tap to the last mine.

1. Read every number as an exact rule

A number tells you exactly how many mines touch that square, counting all 8 neighbours (fewer on an edge or corner). Not "about" that many: exactly that many. A "1" touching only one unopened square means that square is a mine. A "2" that already has two flags next to it means every other neighbour is safe. Treat each number as a small puzzle with one correct answer.

2. How to start a game

In Playnook Games' Minesweeper your first tap is always safe, because the mines are placed after it. Tapping near the middle of the board gives you the best chance of opening a large empty area to work from. Once you have an opening, never tap randomly again: every next move should come from a number.

3. The two basic moves

Find the mines. If a number equals the count of unopened squares around it, all of those squares are mines. Example: a "2" with exactly two unopened neighbours. Flag both.

Find the safe squares. If a number already has that many flags around it, all its other unopened neighbours are safe. Open them, or tap the number to clear them all at once (this is called chording).

Repeat these two moves around the edge of the opened area and you will solve most of an Easy board without any patterns at all. Flag a mine the moment you are sure of it, so you never have to remember it and never tap it by mistake.

4. Patterns to memorise

These patterns appear along a straight edge: a row of numbers with a row of unopened squares right next to them. Learn them once and you will spot them in every game.

The 1-1 pattern. Two 1s side by side, starting at a wall or at an already-solved square. The first 1 can only have its mine in the first two squares next to it. Those same two squares also touch the second 1, so the second 1 is already satisfied. The third square along, next to the second 1, is safe.

The 1-2 pattern. A 1 next to a 2. The 2 needs two mines, but the 1 beside it allows only one mine in the squares they share. So the 2's other mine must be in the square that only the 2 touches: the square on the far side, next to the 2 and away from the 1. Flag it.

The 1-2-1 pattern. Three numbers in a row: 1, 2, 1. The squares next to each 1 are mines, and the square next to the 2 in the middle is safe. This is the most common pattern in Minesweeper, so it is worth learning first.

Mine	Safe	Mine
1	2	1

The 1-2-2-1 pattern. Four numbers in a row: 1, 2, 2, 1. The two squares next to the 2s are mines, and the two outer squares next to the 1s are safe.

Safe	Mine	Mine	Safe
1	2	2	1

A useful way to remember them: when the numbers rise, a mine sits on the side of the bigger number. When the pattern is balanced (1-2-1, 1-2-2-1), the mines sit in the matching positions and the rest are safe.

5. The subtraction trick

When no simple pattern fits, compare two neighbouring numbers. This works when every unopened square next to the smaller number is also next to the bigger number. Subtract the smaller number from the bigger one: the difference is exactly how many mines are in the squares that only the bigger number touches.

Example: a 3 sits next to a 2. All of the 2's unopened neighbours also touch the 3, and the 3 has one more unopened square of its own. The difference is 3 − 2 = 1, so that extra square is a mine. If the difference had been 0, the bigger number's own squares would all be safe.

This one trick solves most positions that look like a guess at first sight.

6. Use the mine counter at the end

The counter at the top shows how many mines are left. Near the end of a game, this number can solve the last squares for you. If two unopened areas remain and the counter says only one mine is left, and one area must contain a mine, the other area is completely safe. Always check the counter before you guess.

7. When you really have to guess

Sometimes the board allows two answers and no logic can tell them apart, for example two squares where exactly one is a mine and nothing else touches them. That is a true 50/50, and no strategy can avoid it. When it happens:

Guess early, not last. If you can see an unavoidable guess, take it before you spend time solving the rest of the board.
Pick the lowest risk. A square far from all numbers has a chance of roughly the mines left divided by the unopened squares left. Compare that with the risk of the squares near the numbers and choose the smaller one.
Prefer squares that give new information. A corner is often a good choice: it is not safer than any other unknown square, but it is the most likely to be a 0 and open a big area.

8. Common mistakes that cost games

Tapping randomly after the first opening. Once you have numbers on the board, every move should come from a number. A random tap on a 15% board is a 1 in 7 chance of losing.
Forgetting the diagonals. A number counts all 8 neighbours, including the four corners around it. Many "impossible" positions are just a missed diagonal.
Placing a flag you are not sure of. A wrong flag looks like solved work, and if you then chord that number, a mine goes off. Flag only what the numbers prove.
Ignoring the walls. The edge of the board is a free clue: a number on the edge has fewer neighbours, so it is often easier to solve than a number in the middle.
Leaving the 50/50 to the end. If a guess cannot be avoided, take it as soon as you see it. Losing early costs less time than losing after you solved everything else.
Rushing the last few squares. Slow down at the end and check the mine counter. The last squares are where most avoidable losses happen.

9. How to get faster

Speed comes after accuracy. Once you win most Easy games, these habits will cut your times:

Chord whenever you can. Tapping a number that already has all its flags opens every other neighbour in one move, instead of three or four separate taps.
Work along the edge of the open area. Move in one direction around the border instead of jumping around the board. Your eyes will spot patterns faster.
Solve patterns by sight. After a few games the 1-2-1 and 1-2-2-1 shapes jump out at you without counting. That recognition is most of the speed difference between new and experienced players.
Only flag what you need. Some fast players flag only the mines they need for chording. On a phone, flagging is still useful, because a stray tap on a flagged square does nothing.

10. A simple practice plan

Board difficulty depends on mine density: the share of squares that hide a mine. On Playnook Games, Easy is 10 mines on 81 squares (about 12%), Medium is 20 mines on 144 squares (about 14%), and Hard is 35 mines on 225 squares (about 16%). For comparison, the classic Windows Expert board was 99 mines on 480 squares (about 21%).

Week 1, Easy: play without any guesses until you win 5 games in a row. Say each rule out loud in your head: "this 1 is done, so these are safe".
Week 2, Medium: focus on spotting 1-2-1 and 1-2-2-1 patterns and on the subtraction trick.
Week 3, Hard: practise the mine counter at the end and the "guess early" rule. Try to beat your best time shown at the top of the game.

Ten minutes a day is enough. Minesweeper rewards steady, careful practice more than long sessions.

Put the logic to work

Try the patterns on Easy (9×9, 10 mines), then step up to Medium and Hard. Your first tap is always safe, and tapping a number with the right flags clears its neighbours instantly. It also works with screen readers.

Minesweeper FAQ

Can you win Minesweeper without guessing?

Most of the time, yes. On Easy boards almost every game can be solved with pure logic. On bigger, harder boards you will sometimes reach a spot where the numbers allow two different answers, and then a guess is unavoidable. Good players keep those guesses rare and make them as safe as possible.

Is the first click in Minesweeper always safe?

In Playnook Games' Minesweeper, yes. The mines are placed only after your first tap, so the first square you open is never a mine.

What is the 1-2-1 pattern in Minesweeper?

Three numbers in a row reading 1, 2, 1 along a straight edge of unopened squares. The two squares touching the 1s are mines and the square in the middle, touching the 2, is safe.

Where should I guess in Minesweeper?

Guess where the chance of a mine is lowest and where a safe answer helps most. A square far from all numbers usually has a chance close to the remaining mines divided by the remaining unopened squares. A corner is often the best choice because it is the most likely to be a 0 and open a big area.

What is chording in Minesweeper?

When a number already has as many flags around it as its value, tapping that number opens all its other neighbours at once. It is fast, but a wrong flag will set off a mine, so only flag squares you are sure about.

How do you play Minesweeper?

Tap any square to open it. A number shows how many mines touch that square, counting diagonals. Use the numbers to work out which hidden squares are mines, flag them, and open every safe square. You win when all safe squares are open, and you lose if you open a mine.

Is it possible to beat Minesweeper every time?

Not every time. Most boards can be cleared with logic alone, but some boards reach a point where two answers fit the numbers and you must guess. On Easy boards this is rare. With good pattern reading and smart guesses, a strong player wins most Easy games and a good share of Hard ones.

Why do I keep losing at Minesweeper?

Most losses come from tapping randomly after the first opening, forgetting diagonal neighbours, or placing a flag you were not sure about and then chording it. Make every move come from a number and only flag what the numbers prove.

What is a good mine density for beginners?

Start with around 12% mines, like the Easy 9 by 9 board with 10 mines. Move up to Medium (about 14%) and Hard (about 16%) once you can win Easy games without guessing.
