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. A 1-1 along a wall means both 1s share the same mine, letting you safely reveal cells past the second 1. A 1-2-1 in a row means the mines sit under the outer 1s, and the cells behind the center 2 are safe. Corner cells with a single unrevealed neighbor adjacent to a 1 are always mines. Beyond named patterns, the general technique is constraint subtraction: when one number's constraint is fully contained in another's, subtract them to identify guaranteed mines or safe cells. Start at edges and work inward.
