How to play Minesweeper properly

Minesweeper looks like luck to people who click randomly and logic to people who know five patterns. The gap between the two is about twenty minutes of reading, which is what this is.

The rules in one minute

Every number counts the mines among its eight neighbours — that is the whole game. Left-click reveals a square; right-click (long-press on a phone) flags a suspected mine; clear every safe square and you win. In the Pikkit version, as in all modern versions, the first click is always safe and opens an area — mines are placed after it.

A revealed 0 shows blank and auto-reveals its neighbours, which is why one click can cascade a whole region open. Numbers only ever describe their own eight neighbours; beginners repeatedly forget the diagonals count.

Opening play

Open somewhere central — corners and edges give numbers fewer neighbours to describe, which sounds helpful but actually strangles information flow. Chase the cascades early: the fastest openings are clicks adjacent to already-open regions, expanding the border where numbers give you leverage. Flag only what logic proves; speculative flags are how boards die, because every later deduction trusts them.

The patterns that solve boards

• Satisfied numbers. A 1 touching exactly one hidden square: that square is the mine. A 1 whose mine is already flagged: every other neighbour is safe. This single rule clears half of every beginner board.
• 1-2-1 along a wall: the mines sit under the 1s, and the square under the 2 is safe. Memorise it as a shape.
• 1-2-2-1 along a wall: mines under the 2s, safety under the 1s. The sibling shape.
• Counting the remainder. A 3 with one flagged neighbour behaves as a 2 for its remaining squares — numbers minus flags is the live count, always.
• Subset logic. When one number's unknowns are a subset of a neighbour's, subtract: if a 1 and a 2 share two squares and the 2 has one extra square, that extra square is a mine. This is the pattern that separates intermediate from expert play.

Chording: where speed lives

Click a revealed number whose flags equal its value and every remaining neighbour opens at once — chording. It converts flag-then-click-each-square into flag-then-one-click, and it is the entire difference between minutes and seconds on a board. The rhythm of good play is: flag the proven mine, chord the satisfied numbers around it, watch the border collapse. World-class times — beginner boards under 10 seconds, expert under 40 — are chords nearly all the way down.

When guessing is forced

Sometimes logic genuinely runs out: the classic is a 50/50 behind a wall where two squares are symmetric and nothing distinguishes them. This is a property of the game — Minesweeper's general problem is NP-complete, and some positions are provably information-free — so a lost forced guess is the game being the game, not you failing. Practical guessing: prefer squares that resolve the most future information, and prefer the corner-most option in end-game 50/50s (mine density arguments give it a sliver of an edge on some layouts). Then accept the coin flip with dignity — the randomness guide covers why the board owes you nothing.

A short history of a time thief

Shipped with Windows 3.1 in 1992 — allegedly to teach a generation right-clicking, a job it performed magnificently — Minesweeper became one of the most-played games in software history from inside a Start menu. The competitive scene it spawned still runs world rankings today. Best times per board size are kept on your device in the Pikkit version; when the 50/50s have taken their toll, 2048 and an unbeatable tic-tac-toe are the neighbouring time thieves, and Pikkit holds the rest of the arcade.
