Each number shows exactly how many mines are hidden in the eight squares surrounding it (including diagonally adjacent squares). For example, a "3" means three of the surrounding eight squares contain mines. Use this information to logically deduce which squares are safe to click and which contain mines.

Beginner mode uses a 9x9 grid with 10 mines (11% mine density). Intermediate jumps to 16x16 with 40 mines (15.6% density). Expert mode features a massive 30x16 grid containing 99 mines (20.6% density). Higher difficulties require more advanced logical reasoning and pattern recognition skills.

Most Minesweeper games can be solved through pure logical deduction, but some situations require educated guessing when multiple valid solutions exist. Expert players minimize guessing by using probability analysis and advanced pattern recognition. The key is systematic logical thinking rather than random clicking.

Chord clicking (middle-click or left+right click simultaneously) is an advanced technique used on revealed numbered squares. When you've flagged the exact number of mines around a number, chord clicking automatically reveals all remaining adjacent squares. This speeds up gameplay significantly and reduces misclick errors.
