Uncover all safe cells without hitting a mine!
Minesweeper was written by Robert Donner and Curt Johnson for Microsoft Windows 3.1 in 1990, and for the next two decades it shipped as a built-in application on virtually every Windows PC sold worldwide. Originally intended to help users become comfortable with left-click and right-click mouse interactions, it quickly evolved into a game with a passionate competitive community. The World Minesweeper rankings track completion times down to the hundredth of a second, with expert-level records sitting under 30 seconds for a 30x16 grid containing 99 mines. At its core, Minesweeper is a logic puzzle. Each revealed number tells you exactly how many of its eight neighboring cells contain a mine, and skilled players chain deductions across the board without ever needing to guess. PlayBrain's version offers Beginner, Intermediate, and Expert grids, a running timer, and flag tracking for a faithful desktop-quality experience in your browser.
