The solitaire game included in Windows 1990 was called
"Microsoft Solitaire" , though it was often simply referred to as
"Solitaire" .
It was a digital version of the classic card game Klondike, which is still the most popular type of solitaire today.
Enquanto outros jogos de Solitaire estavam disponíveis em computadores pessoais na época, a inclusão da Microsoft Solitaire no Windows 1990 tornou incrivelmente popular and helped introduce millions to the game.
