Classic Minesweeper online
Play Minesweeper free at ClassicWorks
ClassicWorks Minesweeper keeps the familiar square board, numbered clues, flags, and tense logic of the traditional game, then adds a responsive layout, first-action safety, undo, hints, local statistics, and shareable numbered games.
Choose a difficulty
Beginner uses a 9 by 9 board with 10 mines. Intermediate expands to 16 by 16 with 40 mines. Expert uses the classic 30 by 16 layout with 99 mines for players who want the full deduction challenge.
Play random or numbered boards
Random games create a fresh challenge with a visible seed. Numbered games let every player open the same board for the same game number, difficulty, and generator version, making shared challenges and community best times possible.
Use safe starts, flags, and chording
The first board action starts the timer and opens a safe position. Mark suspected mines with flags, reveal safe cells, and use chording when a revealed clue already has the correct number of neighbouring flags.
Learn the logic
The guides explain direct rules, 1-1 and 1-2 edge patterns, 1-2-1 and 1-2-2-1 positions, geometric variants, reductions, mine counting, and advanced endgame checks.
