About this tool
Open every square that has no mine, using the numbers as clues. A number tells you how many of the eight touching squares hold mines. Boards are generated inside your browser and nothing is sent to a server. There are three sizes โ beginner 9x9 (10 mines), intermediate 16x16 (40), and expert 30x16 (99) โ and you win the instant every non-mine square is open. Mine placement depends on where you make your first tap though, so playing the same board over a shared link only works if you start on the same square.
How to use
- Choose beginner 9x9 (10 mines), intermediate 16x16 (40) or expert 30x16 (99).
- Tap a square to open it. Your first tap is never a mine, and its neighbours are clear too, so the board opens up.
- Flag squares you think hold mines โ right-click, long-press, or switch on Flag mode and tap.
- Double-click (or middle-click) an already-open number to clear the rest around it, once the flag count matches.
- Share the link and your friend plays the same board.
- Watch the remaining-mine count and elapsed time at the top to track your progress.
- Open every non-mine square to win, or open a mine to lose instantly โ you never have to flag every mine.
Frequently asked questions
- Can I die on the very first tap?
- No. Mines are not placed until after your first tap, and the eight squares around it are kept clear too, so the first move always opens an area.
- How do I flag on a phone?
- Long-press a square (0.4s) or switch on Flag mode and tap. Long-press clashes with browser gestures on some devices, which is why the mode button is there too.
- I tapped a number and suddenly died.
- Double-clicking an open number clears everything around it once the flag count matches. If a flag was in the wrong place, a real mine gets opened โ convenient but risky, which is why a single click does nothing there.
- Does the shared link give the same board?
- Yes, the address carries a board number. Note that mine placement depends on where you first tap, so start on the same square to get an identical game.
- Do I have to flag every mine to win?
- No. You win the moment every non-mine square is open. Flags are just markers to help you avoid opening the wrong square by accident, not a win condition.
- What happens if I place more flags than there are mines?
- The remaining-mine counter at the top just goes negative โ there is no other penalty for flagging more squares than there are actual mines.
- When does the timer start?
- It starts the moment your first tap generates the board, and stops once the game ends. The clock does not run before your first tap.
- What happens to my game if I change difficulty?
- Clicking a difficulty button resets every opened square and flag and starts fresh with a new board number. You cannot resume the previous game.
- Can I see where the mines were after I lose?
- Yes. Once you hit a mine, every remaining mine on the board is revealed so you can see exactly where things went wrong.
