How to play Mine Field
What the numbers mean
A revealed square shows how many of the eight squares around it contain a mine. A blank square means none of its neighbours do, which usually opens up a large area at once.
The first tap is always safe
The board places its mines after your first tap, avoiding the square you chose and its neighbours. Starting a round on a guess would make the first move a coin toss, which is not what a logic game should open with.
Marking squares you are sure about
Hold or long-press a square to flag it. Flagging is only a note to yourself — it never protects a square, and you can unflag it at any time.
Solving by reasoning, not guessing
There is always a deduction available from the numbers already showing, so the round does not require a guess. If it feels like one, look for a number whose remaining mines are fully accounted for by its neighbours.
How the round ends
Revealing a mine ends the round. Clearing every square that is not a mine wins it, and the timer is there for your own reference rather than as a limit.
Mine Field Tips and Strategy
Open in a corner
A corner square has three neighbours instead of eight, so it is far more likely to be blank and far more useful when it is. A blank corner opens two borders at once, while a square in the middle usually reveals almost nothing. Since the first tap is always safe, spend it there.
Read the numbered band
When three revealed numbers in a row read 1, 2, 1, the cells under the outer two are mines and the cell under the middle one is safe, as long as nothing else is unrevealed beside them. Recognising those shapes is much faster than expanding square by square, and it never needs a guess.
Flag only what you proved
Flagging is bookkeeping and it never protects a square, so use it for deductions only. If a numbered square shows 2 and touches exactly two squares you have not resolved, both of those are mines. Marking them turns a blank region back into information, which is usually the only way a tight corner opens up.
Mine Field — Frequently Asked Questions
Can I lose on the first tap?
No. The mines are placed after your first tap, so the opening square and its neighbours are always clear. That first tap often opens a wide area, which gives you something to reason from.
Do I have to flag squares?
No, flagging is optional and only for your own bookkeeping. The board is won by revealing every non-mine square.
Is guessing ever required?
Not in this version. Every round is generated so a deduction is always available from the numbers on screen.
Does it need installing or an account?
No. It runs in the browser on a phone, tablet or computer and works offline after the first visit.
