Expert Minesweeper — Play Free Online (16×30, 99 mines)

Expert Minesweeper

Expert Minesweeper is the highest of the three classic difficulties: a 16×30 board hiding 99 mines. This is where competitive Minesweeper players live. The density is high enough that you will face real 50/50 guesses in almost every game, and the board is wide enough that efficient flagging and pattern spotting matter more than raw clicking speed. Clearing Expert cleanly is one of the most satisfying feelings in puzzle gaming.

This Expert board is free to play, runs in any modern browser, and includes full keyboard controls for users who prefer to skip the mouse entirely. First-click safety, local best-time tracking, and flag support are all built in. New to the game? Warm up on Beginner or Intermediate first.
