Clear the board without hitting a mine. Choose a classic difficulty or try No-Guess mode and start immediately.
Reveal every safe square without opening a mine. Each number tells you how many mines touch that square, including diagonally. Use those clues to identify safe cells and mark suspected mines with flags.
No-Guess mode searches for boards that the built-in solver can complete using logic. Generation has an attempt limit: if no suitable board is found, the game clearly marks the fallback as a standard board, which may require guesses. A successfully generated No-Guess board can still require advanced deductions.
