Game Objective

Open every safe square without opening a mine. A number on an opened square tells how many mines are hidden in the ring of neighboring squares around it, including diagonal neighbors.

Find all the mines without treading on any of them.

How to Play

Left-click a covered square to open it. Right-click a covered square to place or remove a flag when you think it is a mine. If a numbered square already has the right number of flagged neighbors, click that number to open all its other covered neighbors.

These puzzles reward careful deduction more than speed. Start with the most constrained clues, eliminate impossible choices step by step, and avoid guessing unless the puzzle specifically calls for it.

Beginner Tips

  • If a 1 has only one covered neighbor left, that neighbor must be a mine, so flag it.
  • If the number already matches the flags around it, every other covered neighbor is safe to open.
  • The first square you open is safe. After that, work from opened numbers instead of guessing whenever possible.
