Your first round
- Make a first reveal to open a safe area.
- Find a clue whose number equals its remaining hidden neighbors; those neighbors must all be mines if the other surrounding squares are known safe.
- Once the clue’s mines are correctly accounted for, reveal its other neighboring squares individually.
- Compare overlapping clues along the frontier before considering an uncertain square.
Worked example
Make the idea concrete
Account for one mine
A revealed 1 has only two hidden neighbors, A and B. Another clue proves A is a mine. The 1 already has its mine, so B is safe. The deduction depends on A being proven, not merely flagged.
Build your strategy
- Check whether two nearby clues share hidden neighbors; subtracting known information can expose a safe square.
- Revisit the frontier after every reveal because a new clue can resolve an earlier uncertainty.
- On mobile, verify whether Flag mode is on before touching a square.
Common mistakes
- Ignoring diagonal neighbors when counting around a clue.
- Treating all flags as confirmed facts, or assuming the safe opening guarantees a guess-free board.
