Minesweeper feels like a guessing game once the board gets complicated, but the overwhelming majority of positions are fully solvable through logic alone — you just need to know what to actually look for.
What the numbers really mean
Each revealed number tells you exactly how many mines touch that square, out of its up-to-8 neighbors. The entire game is a constraint-satisfaction puzzle wearing a simple visual disguise — every number is a hard rule about a small local area, not a hint or a probability.
The "satisfied number" rule
If a numbered square already has exactly that many flagged mines adjacent to it, every other unrevealed neighbor of that square is guaranteed safe. This single rule alone solves a huge share of positions that feel like guesses to players who haven't internalized it — you're not guessing, you're just not tracking the constraint yet.
The "all mines found" rule, in reverse
If a numbered square's count of unrevealed neighbors exactly equals its number, every one of those unrevealed neighbors must be a mine — even without any of them being individually confirmed yet. This is the counterpart to the safe-square rule, and just as reliable.
Start from corners and edges
Corner and edge squares have fewer neighbors than middle squares, which means their constraints are easier to fully resolve early. Our Minefield build benefits from this the same way the original does — starting your logic chain from the areas with the fewest unknowns gives you a foothold to expand from.
When a genuine 50/50 guess is unavoidable
Occasionally a board position really does reduce to a true coin-flip with no further logical resolution possible — this happens, but it's much rarer than most players assume. If you find yourself guessing on move two, you've almost certainly missed an application of one of the two rules above rather than hit a genuinely unsolvable spot.
Play Minefield and try solving a full board without a single guess, or if constraint-based logic is what you enjoy, Sudoku runs on a very similar underlying reasoning style.
