Here's a bit of interesting solitaire trivia for you: What do you think is the first Klondike solitaire game for the PC? If you thought of the traditional Windows solitaire, you're wrong by about 8 years. Brad Fregger submitted his Solitaire Royale
as the first version of Solitare for the home computer, and after some research, I was able to confirm aspects of that claim -- at least for the PC. Klondike Solitaire
(1984) was actually the first Klondike that resembled today's common solitaire, with exclusive mouse support, but was crude. Solitare
(sic), released a year later, contains some more options (including an innovative "same deck" option that actually allows you to play competitive solitare
against other players), but didn't contain mouse support. Solitaire Royale
came out two years later in 1987, was published by Spectrum Holobyte, had mouse support, and also contained very many solitaire variations in addition to Klondike.
So, Brad gets to keep his claim of "first ever commercial solitaire card game software for the PC". (And Macintosh too.) Whether or not it was the first commercial solitaire game ever for any
platform remains to be seen, but we won't know the answer to that one until MobyGames adds a gazillion more platforms. ;-)
