Slow down the decision

Before each move, ask what information is certain, what is only possible and what consequence the move creates.

Use a repeatable strategy

When a number already touches the required number of flags, its other neighbours are safe.

When the number of covered neighbours equals the remaining mines, flag them all.

  • Start by opening space and reading the boundary numbers around revealed areas.
  • A number tells you exactly how many adjacent cells contain mines.

Recover from mistakes

A weak move does not always end the round. Reassess the board, protect the most important area and avoid compounding one mistake with another rushed decision.

What to avoid

Use these mistakes as a quick checklist before important moves.

  • Guessing before checking every available clue.
  • Treating a flag as proven when it was placed speculatively.
