Medium Minesweeper
Medium Minesweeper
This 16 × 16 board has 40 mines. A 2 means two mines touch that square. Find one, then use nearby numbers to look for the other.
Each new game opens the center safely with an animation. The numbers let you find at least one safe next move. Later, you may need to guess.

When the flags around an open number match its count, click that number to open the other covered squares around it. This is called chording. Check each flagged mine with the numbers first. A wrong flag can cause you to open a mine.
Move the pointer to see nearby hints. On a touchscreen, all hints stay visible. A small circle with a pale green edge marks a safe square. A faint mine icon marks a mine. Hints use the visible numbers and total mine count. Check your flags against the numbers.
Use the arrow keys to move between squares. Press Enter or Space to open a square. F adds or removes a flag. N starts a new game. Your best times stay in this browser.
Read the board, then choose
The left 1 counts mines in A and B. The next 2 counts mines in A, B and C. Subtract the first count from the second. C must hold the extra mine. Use the same method with larger groups.
Choose a covered square. Then decide whether it is safe, has a mine, or needs more information.
Why this answer is correct
A: Not enough information · B: Not enough information · C: Mine
The shown covered squares are the only unknown squares around these numbers. Gaps stand for open squares or the board edge. Check every nearby square before you apply the result. Flags in these examples mark known mines.
