Fifty years of the world's most famous logic puzzle — from mainframe curiosities to browser games.
Few games have a lineage as long and tangled as minesweeper. Before it became the ubiquitous desktop time-killer, its core idea — deduce hidden mines from numbered clues — passed through mainframes, home computers, and shareware packs. Here is how it happened, and where the game goes next. You can play the modern version right here at Bean Boom.
The earliest known ancestor is Cube, written by Jerimac Ratliff in 1973. It was a three-dimensional mine puzzle played on the cubes of a larger grid — literally "minesweeper in a cube" — and already centered on navigating a minefield using logic rather than luck.
In 1983, British developer Ian Andrew released Mined-Out for the ZX Spectrum. Mined-Out moved the concept to a two-dimensional grid and told the player exactly how many mines sat in adjacent squares — the defining mechanic of modern minesweeper, born on a home computer with 48 KB of memory.
Then in 1985, Relentless Logic (also known as Logic Game) appeared on MS-DOS. It sent the player across a minefield toward a destination, using adjacency counts as a guide. Within a couple of years the formula had been simplified into the reveal-and-flag game we recognize: a grid, hidden mines, numbers, and the goal of clearing the board.
Robert Donner and Curt Johnson, working at Microsoft, wrote Minesweeper for the Microsoft Entertainment Pack in 1990. Johnson had written an earlier OS/2 mine game; Donner rebuilt the concept with the now-classic smiley face, flags, and timer.
The decisive moment came in 1992, when Microsoft bundled Minesweeper with Windows 3.1. Overnight, the game reached virtually every office and home computer on the planet. For hundreds of millions of people in the 1990s, minesweeper was not just a game — it was the game, the first icon you double-clicked on a new PC. The game taught an entire generation basic mouse skills: left-click to reveal, right-click to flag.
Through Windows 95, 98, XP, and beyond, minesweeper remained a fixture. Around it grew a culture:
Microsoft stopped bundling the classic games with Windows 8 (2012), moving minesweeper to its store as a downloadable app. By then it hardly mattered: the game had long escaped Windows entirely. Today minesweeper lives on the web, where browser versions add modern features the 1990 original never had:
Minesweeper survives every platform shift because its core loop is nearly perfect: every click gives information, every number is a tiny logic puzzle, and every board is a fresh test of deduction. It requires no language, no tutorial beyond one page of rules, and thirty seconds to learn — yet players spend years mastering patterns and strategy. Fifty years after Cube, the minefield is still expanding.
Minesweeper evolved from earlier grid-based mine games rather than being invented at once. Key ancestors include Jerimac Ratliff's Cube (1973), Ian Andrew's Mined-Out (1983), and Relentless Logic (1985). Robert Donner and Curt Johnson created the Microsoft Windows version released in 1990.
Microsoft Minesweeper shipped with the Microsoft Entertainment Pack in 1990 and was bundled with Windows 3.1 in 1992, which made it famous worldwide.
Microsoft stopped bundling the classic games with Windows 8 in 2012 as built-in apps moved to the company's store. Minesweeper returned as a free downloadable app, and countless web versions now carry the tradition.
