Play Minesweeper: Classic Puzzle Game

1. Board — a grid of hidden cells covering mines. 2. Click to reveal — uncover a cell. 3. Number clue — if safe, a number shows mines in adjacent cells (0–8). 4. Flag mines — right-click to flag suspected mines. 5. Win — reveal all non-mine cells. 6. Lose — click a mine; game over.

• Beginner — 9×9 board, 10 mines. Easy for learning.
• Intermediate — 16×16 board, 40 mines. Medium challenge.
• Expert — 30×16 board, 99 mines. Hard, requires advanced logic.

• Numbers are clues — a "3" means exactly 3 adjacent mines.
• Empty cells — 0 mines adjacent. Cascade reveals many cells.
• Mark and reason — flag cells, then deduce from numbers.
• Isolated regions — focus on one area first, then expand.

• First click is safe — the board generates after your first move.
• Work from edges — borders have fewer adjacent cells, easier to deduce.
• Probability guessing — when stuck, pick the cell with fewest adjacent mines.
