's history is a blend of evolving logic puzzles, a secret Microsoft training mission, and even international controversy. 
1. The Pre-Windows Era (1960s–1980s)
While often associated with Microsoft, the core gameplay of navigating a grid using numerical clues dates back decades:
  • Early Concepts (1960s–70s): Early mainframe games like Cube featured similar mechanics.
  • Mined-Out (1983): Created by Ian Andrew for the ZX Spectrum, this is often cited as the first true "Minesweeper" game, featuring a grid where players had to cross a field by identifying mine locations.
  • Relentless Logic (1985): An MS-DOS game that further refined the formula, tasking the player with delivering a message through a minefield. 
2. The Microsoft Revolution (1990–2012)
The version most people know was created by Microsoft employees Curt Johnson and Robert Donner. 
  • First Appearance (1990): It debuted in the Microsoft Entertainment Pack 1 for Windows 3.0.
  • The Secret Purpose: Microsoft didn't just include it for fun; the game was designed to train users on how to use a mouse. It taught the difference between left-clicking (to reveal) and right-clicking (to flag), which were new concepts for many at the time.
  • Standard Install (1992): It replaced Reversi as a standard pre-installed game in Windows 3.1, remaining a staple through Windows 7
