Intermediate Minesweeper — Play Free Online (16×16, 40 mines)

Intermediate Minesweeper

Intermediate Minesweeper is the middle of the three classic difficulties — a 16×16 board with 40 mines. It is the sweet spot most experienced players settle into: big enough to produce interesting pattern-recognition moments, but not so dense that a single unlucky guess ends a five-minute run. If Beginner has started to feel too easy, Intermediate is the natural next step up.

Like every board on this site, Intermediate is free to play, runs entirely in your browser, and needs no signup. Flags, keyboard controls, first-click safety and local best-time tracking are all built in. Ready for the toughest challenge? Jump into Expert Minesweeper next.
