Minesweeper — Windows 98 Simulator

Minesweeper has shipped with Windows since 3.1 and was the office break-time game of the 90s, a gentle way to teach millions of people to use a mouse. Windows 98 kept the grey 3D board, the yellow smiley face and the three-digit LED counters, and recorded your Best Times for each level.
