MinesweeperHow to enter your board
Choose a size, then select a number or flag from the palette and paint the board. Enter every revealed blank as 0. Leave unopened squares covered. A flag means a confirmed mine to the solver, so only enter flags you trust. You can leave the total mine count empty if it is unknown. Playing on this site?

What the colors mean
Green means the square is certainly safe under your entered clues. Red means it must contain a mine. Select a result to read the reason. The solver enumerates independent frontiers and combines them with the remaining mine count to calculate exact probabilities, including unconstrained squares. Exceptionally expensive frontiers remain unscored; absence of a highlight is not evidence of safety.
Is using a Minesweeper solver cheating?
Not when you use it to learn. The solver never sees hidden mines; it only works from the numbers you enter, exactly as you would. Use it after a game, or when you are stuck, and read the reason behind each result. Most explanations turn out to be one of the common Minesweeper patterns. Learning to spot them yourself is the core of our guide on how to win Minesweeper.
