Is Minesweeper a game of skill or luck?

Minesweeper is primarily a game of skill and logic. However, there are situations where you may have to guess (a 50/50 chance), especially at the very end of difficult boards.

What do the numbers mean in Minesweeper?

The number on a square tells you exactly how many mines are touching that square, including the 8 surrounding squares (sides and corners).

Is online Minesweeper free to play?

Yes. Online Minesweeper is completely free to play, with no signup, no downloads and no ads required to start a game.

Does the first click ever hit a mine?

No. In this online Minesweeper, the first click is guaranteed to be safe — mines are placed after your first click, so you always get a fair start.

What difficulty levels are available?

You can play Beginner (9x9, 10 mines), Intermediate (16x16, 40 mines), Expert (16x30, 99 mines), a custom board of your choice, and a daily Minesweeper challenge.
