1-2-1 Pattern • Chording • Corner Openings • 50-50 Probability
Numbers indicate how many mines are hidden in the 8 neighboring adjacent squares. Uncover all non-mine cells to win!
Exactly 1 mine touches this cell in its 8 surrounding neighbors.
Exactly 2 mines touch this cell.
Place a red flag to mark a confirmed mine and prevent accidental clicks!
Click patterns below to master 100% deterministic mine deductions!
When numbers [1] [2] [1] sit in a straight line against an unrevealed wall, the mines are ALWAYS placed directly adjacent to the two [1]s, and the square facing the middle [2] is 100% SAFE!
When a revealed number cell already touches its required number of flags, clicking both mouse buttons (or middle-click) on that number instantly uncovers all remaining unflagged neighbor cells! This speeds up solving dramatically.
Yes! In modern Minesweeper engines, the board generates mine locations AFTER your first click, guaranteeing that your first click is never a mine and often opens a large zero-zone.
When a corner position reduces to a pure 50-50 guess with no mathematical deduction possible, make the guess immediately rather than spending time solving the rest of the board first!
Starting in a corner yields higher odds of opening large zero-zones compared to clicking center cells.
When a 50-50 guess is inevitable in an endgame corner, make the guess early to avoid wasting time!
