Minesweeper Solver: Screenshot, Safe Moves & Odds
Stuck on a Minesweeper board? Upload a screenshot or copy your board below, and the solver shows every guaranteed safe cell and mine. If no move is certain, it shows the exact chance each cell is a mine and highlights your safest guess.
How to Use
- Upload a screenshot of your game, or choose a grid size that matches it
- Select a tile from the palette, then click or drag on the grid to paint cells (or fix any cell the screenshot reader got wrong)
- Mark all revealed numbers and any flags you've placed
- Click Find Safe Moves
- Green cells are safe to click — Red cells are mines
- If no cell is certain, the Yellow cell is your best guess — the numbers on cells show each one's chance of being a mine (%)
- Go to your game, make the moves, come back and update the grid, then solve again
Tip: Hover over a cell and press 0–8 to set a number. Press U for unrevealed, F for flag.
How the Minesweeper Solver Works
The solver works through your board the same way an expert player does, but it checks every possibility.
- Enter your board. Upload a screenshot, or pick your board size (including Google Minesweeper sizes) and mark each cell as a number, a flag, or unrevealed.
- Each number becomes a rule. A 3 means “exactly 3 of my unrevealed neighbours are mines.”
- The solver tries every arrangement. It lists every way the mines could be placed that fits all the numbers at once, and accounts for the total mine count.
- You get the answer. A cell that is safe in every arrangement is green. A cell that is a mine in every arrangement is red. If nothing is certain, each cell shows its mine chance and the safest one is yellow.
Because the solver checks every arrangement rather than a fixed list of patterns, it finds deductions that pattern-based helpers miss, including the long chains of logic that show up on Expert boards.
When You Have to Guess
Some positions cannot be solved with logic, such as a true 50/50 at the edge of the board. The solver then gives you the best odds instead:
- The yellow cell is the one least likely to be a mine.
- The numbers on each cell are the chance (in %) that it is a mine.
- Cells away from the numbers share one probability, based on how many mines are left. Sometimes a random cell in open space is safer than any cell next to a number, and the solver tells you when that happens.
Our probability guide explains the maths behind these odds.
Board Sizes
| Preset | Size | Mines |
|---|---|---|
| Beginner | 9×9 | 10 |
| Intermediate | 16×16 | 40 |
| Expert | 30×16 | 99 |
| Google Easy | 10×8 | 10 |
| Google Medium | 18×14 | 40 |
| Google Hard | 24×20 | 99 |
| Custom | up to 50×50 | any |
When Should You Use a Solver?
- Getting unstuck. Find the next safe move, or the best guess, and keep playing.
- Learning patterns. If the solver finds a safe move you missed, look at the numbers around that cell. You have just found a pattern you did not know. Study it and you will recognise it next time.
- Checking your logic. Run the solver to confirm a deduction before you commit to a risky click.
- Improving your game. Use the solver as a teacher, not a crutch. The goal is to spot every move it finds on your own.
Frequently Asked Questions
Can the solver read a screenshot of my board?
Yes. Click Upload Screenshot, paste an image with Ctrl+V, or drop it on the upload box. The solver finds the grid and reads every number and flag. It works with Google Minesweeper and classic Windows-style boards, and the image is processed on your device, never uploaded. Check the imported board matches your game before you rely on the answer. Full-size screenshots work best.
What happens when there is no guaranteed safe move?
The solver calculates the exact chance that each unrevealed cell is a mine and highlights the safest cell in yellow as your best guess. The percentage on each cell is its chance of being a mine.
Does the solver work with Google Minesweeper?
Yes. Choose Google Easy (10×8, 10 mines), Google Medium (18×14, 40 mines) or Google Hard (24×20, 99 mines) from the Preset menu, then copy your board.
Can I solve a 9×9, 12×12 or other custom-size board?
Yes. Beginner is 9×9 with 10 mines. For any other size, choose Custom and enter the rows, columns and total mines. Any board up to 50×50 works.
Why does the mine count matter?
The total number of mines changes the odds for cells that are not next to any number, and near the end of a game it can make otherwise uncertain cells certain. Enter the total mines for the whole board, including ones you have already flagged.
How accurate are the probabilities?
They are exact, not estimates. The solver counts every arrangement of mines that fits your numbers and the total mine count, and weighs each one by how many ways the remaining mines can be placed. Very large, open boards can exceed the calculation limit. The solver then still shows guaranteed moves, but no odds.
Does the solver work on mobile?
Yes. Tap a tile in the palette (including the flag), then tap cells on the grid to paint them. On desktop you can also hover over a cell and press 0–8, U or F.
