How to get better at Minesweeper: tips for faster, cleaner games

Accuracy before speed

The fastest way to a better best time is to stop losing games. A lost Expert game costs you every second you put into it, and it usually comes from a click you were not sure about. So the first goal is a high win rate: only open a square you have proved is safe, and only flag a square you have proved is a mine.

A useful test: before each click, say to yourself which number or numbers make the square safe. If you can't name them, don't click yet. It feels slow for a few days, then it becomes automatic, and that is when your times start to drop.

This works best on boards that never force a guess. On a no-guess board every loss is a mistake you can find afterwards, so each one teaches you something. On a fully random board some losses are just bad luck, which makes it much harder to tell whether you are improving.

Move up the levels at the right time

The three standard levels get harder in two ways at once: more squares, and a higher share of them are mines. That second number is what makes Expert feel so different.

A good rule of thumb is to move up once you win nearly every game at your current level without hints. Beginner teaches the basic rules and the 1-1. Intermediate is where most of the learning happens: long boundaries, plenty of 1-2-1s, and enough mines that counting matters at the end. Expert adds density, so numbers of 3 and above become common and reduction (subtracting flags you already know) becomes essential.

Learn the patterns until you stop thinking about them

Strong players don't reason out each square. They glance at a row of numbers and already know the answer, because they have seen the same shape hundreds of times. A small set of shapes, 1-1, 1-2, 1-2-1, 1-2-2-1 and the same shapes after subtracting flags, does most of the work on any board. The Minesweeper patterns page has every one with a diagram.

To make them automatic, play Intermediate and deliberately name the pattern before each move. After a week or two you will notice you are no longer naming them; you just see them.

Make fewer clicks

Once you are accurate, speed comes mostly from doing less, not from moving your hand faster. Three habits make the biggest difference:

• Chord. When a number has all its mines flagged, click the number itself to open every other square round it at once. One click can do the work of five or six. (How to play Minesweeper explains chording if you haven't used it.)
• Flag only what you will use. A flag is worth placing when it lets you chord a number, or when it helps you subtract on a crowded part of the board. A mine deep in a finished area that nothing will chord off doesn't need a flag.
• Don't open numbers one by one when an opening will do it. Opening an empty square (a 0) clears a whole area by itself. If you can prove a square is safe and likely to be empty, opening it can save a dozen clicks.

3BV and efficiency: the numbers that show progress

Your time alone can mislead you, because some boards are simply easier than others. Two measures help:

• 3BV is the fewest clicks that could clear a particular board without flags: one for each opening, plus one for each number that isn't on the edge of an opening. A board with a low 3BV is quick for everyone; a high one is a long game whoever plays it.
• Efficiency is the board's 3BV divided by the clicks you actually made, as a percentage. Near 100% means you hardly wasted a click.
• 3BV a second is 3BV divided by your time. It compares your speed across boards of different difficulty, which a plain time can't.

Every cleared game in Yuzool's Minesweeper shows your time, the board's 3BV and your efficiency, and keeps your best time and win streaks for each level. Minesweeper Pro adds your win rate, average time, best 3BV a second and your last ten times, if you like to track trends.

Keep your eyes ahead of your hand

A common reason for slow games is stopping: you finish a move, then start looking for the next one. Fast players look for the next move while their hand is still making the current one.

• Work along the boundary. Follow the edge between open and unopened squares in one direction rather than jumping about the board.
• Finish one region before leaving it. A move often creates the next pattern right beside it, so stay put until that area is done.
• Save the mine count for the end. Counting is slow, and it rarely settles anything until only a few squares are left. When you reach the end, check the counter before you think about any risky move.

On a phone or tablet

Touch play is different from a mouse, and a few settings help. In Yuzool's Minesweeper a tap opens a square (or chords a number) and a hold flags it, with a ring that fills to show when the flag will land. If the hold feels slow, turn on Quick hold in Settings to flag after a fifth of a second. If you prefer, Flag mode swaps the two, so a tap flags and a hold opens; numbers still chord either way.

On big boards, drag with one finger to move round and pinch to zoom. A finger that moves never opens anything, so you can pan freely without fear of a stray click. On an upright phone Expert is turned on its side (16 by 30) so the squares stay big enough to hit. On a computer, the arrow keys (or W, A, S, D) move a cursor, Space opens, F flags and H asks for a hint.

Practise a little every day

Short, regular games beat long sessions. The Daily is ideal for this: one board a day, the same for everyone, 10 by 12 with 20 mines, with your time as the score. Because everyone plays the same board, you can compare a time with a friend fairly, and because it is no-guess, a good time is down to your reading, not luck. Use hints sparingly there: each one adds 30 seconds.

For deliberate practice, use hints the other way round: when you are stuck in a normal game, ask for one, read the sentence that explains it, and notice which pattern you missed. Three hints a game are free.

Habits that hold people back

• Clicking on a hunch. Most losses on a no-guess board are a square that looked safe but wasn't proved.
• Flagging everything. It feels tidy but costs clicks, and one wrong flag can lead to a chord that opens a mine.
• Moving to Expert too soon. Losing most Expert games teaches less than winning most Intermediate ones.
• Only watching the clock. Efficiency and win rate show whether you are actually playing better.
