Fill part of the board with numbers or flags, then click 'Find next move' to check for a solution. Safe squares will be marked with green flags and mines will be marked with red flags
Mines
NEW: 🎉 New and improved solver algorithm! It’s now better than ever at uncovering solutions that used to slip through the cracks.
If the solver cannot find a definite solution, it will mark the squares that have the highest chance of being safe with a ?.
You can now also use a mouse and keyboard keys 0-8, 9, -, + to set the board.
If you ever come across a puzzle where the solver misses a solution that definitely exists, I’d love to hear about it! Just send it my way at .

How to use the Minesweeper solver :
First, select the required board size and the number of mines. This is very important!
Then, fill the board with numbers for the squares you know. First, click on a number to select it. Then click the square on the board to set it.
Click on 'Find next move' or 'Find all moves' and the solver will check for possible moves
If a safe square is found it will be marked on the board with a green flag
If a mine is found it will be marked with a red flag
If the solver cannot find a definite solution, it will calculate for all the remaining squares the probability of being safe. It will then mark the squares that have the highest chance of being safe with a green '?' symbol. For your next move, you will have to make a guess. You can either try the square marked with '?', or make your own guess.
Replace the green flags with the actual numbers and click 'Find next move' again
