Winning at Minesweeper consistently comes down to three things: a good opening, systematic pattern application, and knowing when a guess is genuinely unavoidable versus when you're missing a deduction. Here's the complete picture.
Click near the center, never in a corner. A corner cell has only 3 neighbors — if you hit a number there, you get minimal information. A center cell has 8 neighbors. More cleared cells means more number context means more deductions available.
If your first click reveals a large empty region, great — work outward from the edges of that region. If it reveals a number immediately, click elsewhere in the center to open more territory before trying to deduce from the numbers.
Each number shows the total mines in all adjacent cells — including already-flagged ones. When a cell's mine count is satisfied by its flags, every other unknown neighbor is safe. This sounds obvious but gets missed constantly, especially mid-game when the board is busy.
After every flag: check all numbers touching the flagged cell. If any are now satisfied, click their remaining unknown neighbors immediately.
| Pattern | What you get |
|---|---|
| 1 with one unknown neighbor | That cell is the mine. Flag it. |
| Number satisfied by its flags | All other unknowns around it are safe. |
| 1-2-1 along an edge | Middle cell is a mine, outer cells safe. → |
| 1-2-2-1 along an edge | Middle two are mines, outer two safe. → |
| 1-1 along an edge (shared unknowns) | Mine is in the unique cells, not the shared ones. |
Your mine counter shows unflagged mines remaining. Late in the game, this is crucial. If 3 mines remain and you have 5 unknown cells, the probability per cell is 60% — much higher than the opening rate. Use this to weight your guesses if forced.
Also: if mines remaining equals the number of unknown cells, every unknown is a mine. Flag them all and the puzzle is done.
When a number's mine count matches its flags, clicking on the number itself (chording) automatically clicks all remaining unknown neighbors. This speeds up solving dramatically and reduces clicking errors. Not all implementations support this, but ours does — right-click to flag, then click on the satisfied number.
If you must guess, prefer the guess that opens more territory if you survive. A cell on the edge of a large unknown area, if safe, might clear a dozen cells and give you many new numbers. A cell in a tight corner might give you one new cell. Same odds, different value.
Expert Minesweeper (30×16, 99 mines) has a ~21% mine density. Intermediate (~16%) has more breathing room. On expert, forced guesses are more common — accept this and focus on minimizing unnecessary guesses rather than eliminating all of them.
