Wes Cherry, the man behind Windows Solitaire, decided to create a game during his own time.

Wes explains, "There weren't many games at the time, so we had to make them. So he did precisely that.

After some time, Susan Kare, a renowned graphic designer, became interested in the game. Kare was eventually invited to the Solitaire project to assist with card designs. She is best recognised for creating the icons for the original Apple Macintosh computer.

However, Kare was not the only well-known figure to recognise the game's potential. Bill Gates praised the game as soon as he had a chance to play it. In actuality, his lone gripe was that it was "too difficult to win."

The game was first created by Microsoft to teach users how to operate the computer mouse, but most people just play it for fun.

Speaking of creativity, Cherry included a "boss key" in the game that allowed employees to access a fictitious spreadsheet when they were lax at work.

But ultimately, Microsoft dropped the "boss key." Maybe too many workers were observed playing cards while at work.
