Read one clue and its neighboring squares
Choose a visible number and identify the squares touching it. An interior clue can have eight neighbors: three above, two beside it, and three below. An edge or corner has fewer. A 1 means one mine in that neighborhood, not one mine somewhere farther along the row.
On a narrow screen, some neighboring squares may be outside the currently visible part of the board. Move through the playing area before deciding what the clue touches. The edge of your viewing window is not automatically the edge of the game. Large tiles are useful only if you can inspect the whole neighborhood that matters.
Separate a flag from the reason for it
A flag is a mark you place on a square you believe contains a mine. The mark does not verify itself. If your reason is «this 1 has only one unopened neighbor left,» that is a deduction you can use elsewhere. If your reason is «I had to choose one,» keep that uncertainty separate.
Suppose a 2 touches two mines whose positions are established. Its remaining unopened neighbors are safe because it cannot touch a third mine. But if one of the two flags was a guess, that conclusion is not established. Clear, large symbols make your marks easier to see; they cannot repair an unsupported assumption.
Use two simple rules before looking for patterns
When a clue already has all its mines accounted for, its other unknown neighbors can be opened. When it still needs exactly as many mines as it has unknown neighbors, those neighbors must all be mines. Applying these rules in turn often moves a small game forward without memorizing any named pattern.
Try describing the next move aloud or in a short sentence: «This 1 already touches its mine, so these two squares must be safe.» The purpose is to make your reasoning explicit, not to meet a speed target. If the sentence requires an assumption, examine another clue that shares some of the same squares.
Keep the board and controls comfortable to use
The large-tile view is active when you arrive. Use your browser’s regular zoom for additional enlargement, and move within the board to inspect areas that no longer fit on one screen. Before opening a square, check its boundaries and whether you are revealing a square or placing a flag.
Take particular care after moving the visible area. Find a recognizable clue and check whether you are opening a square or placing a flag. If you need to interrupt, pause and reorient yourself when you return. A comfortable view supports accurate selection; rushing several taps to recover your place can create the opposite result.
Choose a board for the kind of play you want
First-click protection means the opening square and its protected neighborhood do not contain mines when the standard layout is generated. It does not guarantee that every later decision is forced. A separately validated no-guess mode adds a different promise about the reasoning path and must be selected deliberately.
This page is for recreational play with a larger presentation. It does not measure memory, diagnose a condition, or promise to prevent an illness. A loss can come from an incorrect assumption, an accidental selection, or a decision without enough information. You can review the rules, restart, or take a break without turning the result into a judgment about your age or ability.
Frequently asked questions
Are the tiles large from the start?
Yes. This page opens with the large-tile view active; you can enlarge it further with browser zoom.
Do diagonal squares count?
Yes. Clues count all touching mines, including diagonals.
Does a flag confirm a mine?
No. It records your conclusion and can be wrong.
Is this automatically a no-guess board?
No. Large tiles and no-guess validation are different features.
Does the game promise a health benefit?
No. It is offered for recreation without a medical claim.
