Who invented Minesweeper?

The earliest known inspiration for Minesweeper is Mined-Out, created by Ian Andrew and published by Quicksilva in 1983. The Microsoft version was created by Robert Donner and Curt Johnson and shipped with Windows 3.1 in 1992.

When was Minesweeper added to Windows?

Minesweeper was included with Windows 3.1 in 1992. It was originally bundled alongside Solitaire to help users practice mouse skills — clicking, right-clicking, and precise cursor control.

Is Minesweeper still available on modern Windows?

Microsoft removed the classic built-in Minesweeper in Windows 8 and replaced it with a downloadable store version. Today, many players prefer browser-based versions that work on any device without installation.

History of Minesweeper

Minesweeper is one of the most played computer games in history — not because it was marketed aggressively or built around a story, but because it was simply there. Installed quietly on hundreds of millions of PCs, it became a fixture of office desktops, school computer labs, and slow Friday afternoons for decades. Here is how it got there.

The early precursors (1983–1989)

The core concept of navigating a grid full of hidden mines dates back to 1983, when Ian Andrew released Mined-Out for the Sinclair Spectrum through Quicksilva. The game tasked players with crossing a minefield row by row, using numerical hints to identify safe paths. It was simple, tense, and immediately compelling.

Around the same period, Jerimac Ratliff developed Cube, another mine-avoidance game that expanded the concept with a three-dimensional twist. These early games proved that the mine-counting mechanic had genuine appeal as a stand-alone puzzle — not just as a mechanic borrowed from another genre.

Through the late 1980s, variations of the format appeared on multiple platforms under different names. The common thread was the same: a hidden grid, numbered clues, and the constant risk of an invisible instant loss. Players found the combination of logic and tension difficult to put down.

The Microsoft version that reached everyone (1992)

The defining moment in Minesweeper history came in 1992 when Microsoft shipped Windows 3.1. Two Microsoft employees — Robert Donner and Curt Johnson — had built a Minesweeper game as an internal project. Microsoft included it in the operating system alongside Solitaire, framing both games as tools for teaching users how to use a mouse.

The logic was practical: Solitaire taught users to drag and drop, while Minesweeper trained right-clicking and precise cursor placement. In practice, both games became something else entirely — time sinks that employees and students played whenever they could justify it. The "mouse training" framing gave the games a thin layer of productivity cover that suited office environments perfectly.

Windows 3.1 was installed on an enormous number of PCs, and Minesweeper came along for the ride. By the mid-1990s it had become one of the most-played games in the world, not through any deliberate gaming strategy but simply through distribution. Every new Windows machine was a potential Minesweeper machine.

The peak years and quiet ubiquity

Through the Windows 95, 98, and XP era, Minesweeper remained a constant. Its interface barely changed — the smiley face button, the three difficulty modes (Beginner, Intermediate, Expert), the satisfying cascade of blank cells when you opened a safe region. It was a game that rewarded experience without ever demanding it.

Competitive communities formed around speed-running the Expert grid. Players tracked their best times, compared flagging strategies, and debated whether flagging at all was faster than no-flag runs. There was even a world record scene, with players regularly breaking 100-second expert times and eventually approaching sub-40-second clears.

For most players, though, Minesweeper was never about competition. It was the game you played between tasks, during a long phone call, or while waiting for something to compile. It was quiet, self-contained, and always exactly where you left it.

Windows Vista, 7, and the changing landscape

Windows Vista (2007) and Windows 7 introduced a redesigned Minesweeper with updated visuals, new game modes including a flower garden theme, and optional question marks on flagged cells. The familiar smiley face was gone. The new version looked more polished but felt different to longtime players — smoother, but less characterful.

Windows 8 removed the built-in game entirely and replaced it with a downloadable version from the Microsoft Store. For many users that was enough friction to quietly move on. The era of Minesweeper being simply there — always installed, no download required — was over.

The browser-based revival

As the classic Windows version faded, the web kept the game alive. Browser-based Minesweeper clones multiplied throughout the 2010s, ranging from faithful recreations to creative variations on the format. Mobile apps brought the mechanic to touchscreens. Infinite-board versions, multiplayer experiments, and daily-puzzle variants extended the idea in new directions.

The core formula proved remarkably durable. Forty years after Mined-Out, the mine-counting puzzle still works — still produces that particular mix of calm logic and sudden panic that players have always responded to. The platform changed; the game did not.

Where Minesweeping at Work fits in

This site continues the browser-based tradition while adapting the format for how people actually play today — in short sessions, on any device, without setup or installs. The infinite board means there is no fixed grid to complete and no reason to stop partway through. The three-lives system and score structure reward careful play without punishing every single mistake.

If you want to understand the mechanics, the how to play guide covers everything from the first click to the scoring system. For a deeper look at the rules, Minesweeper Rules covers the logic in full detail.
