Why use a Minesweeper solver?

A good Minesweeper solver reduces guesswork. Instead of scanning every pattern manually, you can enter the board once and let the solver check local constraints, subset relationships, and remaining mine counts for you.

This makes the tool useful when you want a quick safe move, when you are stuck in an advanced puzzle, or when you want to study how strong Minesweeper logic works in real positions.

What this Minesweeper solver checks

The solver looks for guaranteed safe cells, guaranteed mine cells, and strong probability candidates when no forced move exists. It can also iterate repeatedly to reveal every currently available logical move with one click.

Because the board is fully editable, it works as an online Minesweeper helper for standard 9x9, 16x16, 30x16, and custom puzzle sizes too.

How to get the best results

Enter clues carefully

The Minesweeper solver is only as accurate as the board you enter. Double-check your revealed numbers and flagged mines before solving.

Use Find All Moves

If one safe move unlocks more logic, the all-moves option keeps iterating to surface every forced move from the current state.

Clear after each step

After applying the suggested moves in your real game, clear the temporary solver marks, enter the new numbers, and analyze again.

Minesweeper Solver FAQs

How do I use this Minesweeper solver?

Match the board size and mine count to your game, enter the revealed numbers and flagged mines, then click Find Next Move. The Minesweeper solver marks forced safe cells and forced mine cells directly on the board.

What do the green and red markers mean?

Green markers are safe squares the solver says can be clicked safely. Red markers are mine locations the solver can prove. If there is no forced move, the solver marks the safest candidates with a question mark.

Can this Minesweeper solver handle custom board sizes?

Yes. You can change the width, height, and total mine count before resetting the board. That makes the tool useful for beginner, intermediate, expert, and custom Minesweeper layouts.

Does this Minesweeper solver work on mobile?

Yes. The board editor and solver controls are responsive, so you can use the Minesweeper solver on desktop and mobile browsers without installing anything.
