Robert Donner is the co-author of Windows Minesweeper.
Robert joined Microsoft in May 1989 around the same time as Curt Johnson1,2. He had previously released two games under the label Casablanca Software and was hired to work on Word for Windows 1.01 which was released on 25 November 1989.
Curt had been hired to maintain a debugger program for OS/23 and he used those skills to write a game that year called "PM Mine" named after his favourite MacIntosh game ("Mine") and the OS/2 windowing system ("Presentation Manager"). The object of his game was to cross a minefield from the bottom left corner to the top right corner using number clues. He shared the source code and Donner released "PM Mine 2.0" in May 1990 with Johnson credited for "original programming" and Donner for "additional programming"4. Windows 3.0 was released on 22 May 1990 and Donner re-wrote the game as "Win Mine"5. The game became so popular at work Bill Gates became addicted6 and it was included as "Minesweeper" in the Windows Entertainment Pack released in October 1990. Two versions of Tic Tac Toe written by Donner were also released in WEP as a combined game called "TicTactics".
Donner wrote several other Windows 3.0 games at Microsoft for fun under the joke label "Duff Software"7:
Robert Donner graduated from the University of Manitoba in 1987 with a Masters degree in Computer Science8,9. In June 1988 he co-founded Casablanca Software in Winnipeg with his friend Gary Gouriluk9 and they released Apple II versions of the classic board games Risk and Clue. The games were published by Virgin Games for multiple platforms under the labels Leisure Genius and Mastertronic10,11. He worked as a senior software engineer at Microsoft in several stints until 20178,9.
