This may seem like a dumb question but I always have thought of "solitair" as a card game. Lately as I have resurched more about games I am seeing games called solitair that look vary different. What is this game really defined as? Is it refered to as any game that is played alone?
Solitair
Some people use the word, "solitaire," to indicate that a game can be played by just one person. "This game is suitable for solitaire play." In this context, solitaire is equivalent to "solo."

In Great Britain, a "patience" game is any card game that is played by only one person. In America, the same idea is called "solitaire". There is no single game by that name, although there is a game (actually a family of close variants) that many Americans just call "Solitaire". Its proper name is "Klondike".
There are hundreds of solitaires that can be played with a standard deck of cards, and more that can be played with two or more decks, or with a partial deck. Now here's a shameless plug: I am the author of Solitaire Till Dawn, a program for Macintosh computers that offers 100 different solitaire card games.
If you'd like to see some of the variety that card solitaires can offer, go to my Rules Index and you can read the rules for each of the 100 games in my program. They can all be played with just cards and a tabletop, no computer necessary. The rules for each game include a brief description of the game, and tips for better play.
Two of the games are my own creations: Tabby Cat and the related (but more difficult) Manx.
