A message from the developer Brad Fregger
My dad inspired Solitaire Royale in this way. My folks were visiting us during the holiday season, 1986, and my dad loved to play cards. One night we promised to play with him, but my mother was playing Shanghai, she'd told us, "Just one more game!" My dad looked at me and said, "I'll never be addicted to a computer game!" The rest of the night all I could think of was what game could I create that would addict my dad? Then it dawned on me that he loved cards, I decided to put card solitaire on the computer (multi-player games were very difficult to sell at this time, so I knew poker wouldn't work...additionally, I wanted something simple, something that didn't need any AI...solitaire was the answer). I went to my publisher (Spectrum Holobyte) with the idea...and the rest is history...computer card solitaire ultimately became "the most played computer game in history." That's a quote from Microsoft.
