Are there patterns in Minesweeper?

Yes. The most important patterns to learn are the 1-1, 1-2, and 1-2-1 formations along walls and edges. Patterns are not tricks - each one is a pre-solved piece of logic you memorise so you can apply it instantly instead of re-deriving it mid-game. Top players are fast mainly because nearly every position they see is already familiar.

The core wall patterns

• 1-1 along a wall: both 1s are constrained by the same mine, so the cells past the second 1 are safe to reveal.
• 1-2 along a wall: the 2 needs one more mine than the 1 can share, which pins the extra mine to the far cell next to the 2.
• 1-2-1 in a row: the mines sit under the outer 1s, and the cells behind the centre 2 are guaranteed safe.
• 1-2-2-1: the mines sit under the two centre 2s; the cells beyond both 1s are safe.
• Corner rule: a corner cell that is the single unrevealed neighbour of a 1 is always a mine.

The technique behind every pattern

All of these reduce to constraint subtraction: when one number's possible mine cells are fully contained inside another number's, subtract the counts. Whatever remains is either a guaranteed mine or a guaranteed safe cell. Once subtraction feels natural you can solve formations that have no name.

How to actually drill them

Play No-Guessing Minesweeper - because every NG board is solvable by logic, each loss tells you exactly which pattern you have not internalised yet. Work edges before the interior, since wall patterns are the most common and the easiest to spot. Then take the speed to the Expert board, where dense 20.6% mine fields make pattern recall the difference between a 60-second and a 150-second clear.
