Medium Minesweeper
Medium boards are 9 wide and 11 tall with 18 mines. Each needs at least one pair step: two numbers that share covered cells, where the difference between them decides the cells only one of them sees.

Medium puzzles need at least one of these techniques, and may use any easier one:
- Two numbers
- These two numbers share some covered cells. However the shared mines fall, the marked cells end up decided.
How to play
Minesweeper is a logic puzzle on a grid of covered cells, some of which hide mines. Open a safe cell and it shows how many mines touch it, counting all eight neighbours. Use those numbers to open every safe cell; flags help you remember where the mines are.
Every board here is no-guess: it starts with an opened area, and from there every cell can be decided by logic. Opening a mine counts as a mistake rather than ending the game, so you can carry on.
- A number counts the mines in the eight cells around it.
- Open every cell that has no mine to clear the board.
- Flags are only a helper; the board is solved once every safe cell is open.
- Opening a cell with no mines around it opens its neighbours too.
Playing on this site
- Choose Open or Flag below the board, then tap a covered cell.
- In Flag mode a tap places a flag, and tapping it again removes it.
- The counter shows how many mines are left once your flags are taken away.
- Hint points out wrong flags and opened mines first, then names the next technique and highlights where it applies.
