Minesweeper no guess is classic Minesweeper with one promise added: the board is always solvable by deduction. In ordinary Minesweeper the mines are scattered at random, so sooner or later — almost always on Expert — you reach two cells that look exactly the same and have to pick one and hope. A no-guess board never asks that of you. If you are careful, you can always work out a safe move.
The game on this page, Logic Minesweeper, builds every board that way. Before you see it, a solver plays the whole board from your first click using logic alone; if it gets stuck, the board is thrown away and a new one is dealt. In our tests every one of 600 boards — 200 on each level — passed, and generating an Expert board takes a few hundredths of a second. Play Minesweeper no guess right here, free, with nothing to install.
How to play Minesweeper No Guess
- Click any cell to start. Your first click is always safe and always opens an area, because neither it nor its eight neighbours can hold a mine.
- Each number tells you how many mines touch that cell, counting diagonals. A blank cell has none, and the game opens its neighbours for you.
- Flag a cell you know is a mine: right-click it, hold it on a touch screen, or turn on Flag mode (or press F) and tap.
- When a number already has all its mines flagged, click it again to open every other cell around it at once (a “chord”).
- Open every cell that is not a mine to win. Your time is the score; the best time on each level is saved.
- Pick New to switch between Beginner, Intermediate and Expert. The “Never require a guess” switch is on by default.

Minesweeper No Guess tips & strategy
- Start with the 1s next to a single covered cell. That cell must be the mine — flag it and the numbers around it start to resolve.
- Look for the 1-2 pattern along an edge. When a 1 and a 2 sit side by side against a wall of covered cells, the cell beside the 2 that the 1 can’t reach is a mine.
- Use the subset rule. If every covered neighbour of one number is also a neighbour of another, subtract: the leftover cells hold exactly the difference in their counts.
- Chord to go fast. Flag the mines around a number and click the number — it opens everything else around it in one go.
- When stuck, look somewhere else. On a no-guess board there is always a safe move; it is usually on another edge of the open area.
- Count the mines left. Near the end, the mine counter often settles which of the last few cells is safe.
What Minesweeper no guess means
A Minesweeper board is no-guess (also called no-guessing or logic-only) when it can be cleared from the first click using only what the numbers tell you. It does not mean the board is easy: Expert no-guess boards still need the subset rule and long chains of reasoning. It only means the board is fair — every loss is your mistake, not bad luck.
Random boards are not fair in that way. On Expert, with 99 mines in 480 cells, most randomly placed boards contain at least one spot where the information runs out and the only way forward is a 50/50. That is why players who care about times and streaks look for Minesweeper no guess: a lost game should teach you something.
How each Minesweeper no guess board is checked
Logic Minesweeper waits for your first click, then places the mines away from it and plays the board itself before showing it to you. The built-in solver opens every cell that a number proves safe, flags every cell a number proves to be a mine, and applies the subset rule between neighbouring numbers. If that clears the whole board, it is yours. If not, the mines are placed again — up to 400 times.
| Level | Board | Mines | No-guess boards in our test |
|---|---|---|---|
| Beginner | 9 × 9 | 10 | 200 of 200 |
| Intermediate | 16 × 16 | 40 | 200 of 200 |
| Expert | 30 × 16 (16 × 30 on a phone held upright) | 99 | 200 of 200 |
The line under the board tells you what you got: “This board never needs a guess”. If a board ever could not be made logic-only within those 400 tries, it would say “This board may need one guess” instead — the game does not pretend.
Minesweeper no guess vs. classic Minesweeper
| Classic random boards | No-guess boards (this page) | |
|---|---|---|
| First click | Safe in most versions | Safe, and always opens an area |
| Forced 50/50s | Common, especially on Expert | Never |
| Difficulty | Logic plus luck | Logic only — still hard on Expert |
| Best times | Partly decided by luck | Comparable from game to game |
| Switch it off? | — | Yes: untick “Never require a guess” under New |
Minesweeper no guess on a phone or Chromebook
On a touch screen, tap to open and hold for about a third of a second to flag; if you prefer, switch on Flag mode so a tap places a flag instead. The Expert board turns to stand 30 cells tall when the screen is upright, so the cells stay big enough for a finger, and lies 30 across on a laptop or in fullscreen. Your best time on each level is stored in this browser.
Minesweeper No Guess FAQ
Is this Minesweeper no guess game free?
Yes. Logic Minesweeper is free to play in your browser, with no download, sign-up or time limit.
Is every board really solvable without guessing?
Every board is checked by a solver before you see it, and the note under the board says so. In our test of 600 boards across all three levels, every one was logic-only.
Does no guess make Minesweeper easy?
No. It removes luck, not difficulty. Expert boards still need careful reasoning, including the subset rule; you just never lose to a coin flip.
How do I flag a mine?
Right-click the cell, hold it on a touch screen, or turn on Flag mode (or press F) and click.
What sizes are the levels?
Beginner is 9×9 with 10 mines, Intermediate 16×16 with 40, and Expert 30×16 with 99 — the classic sizes.
