Poker is a card game, the most popular of a class of games called vying games, in which players with fully or partially concealed cards make wagers into a central pot, which is awarded to the player or players with the best combination of cards or to the player who makes an uncalled bet. Poker can also refer to video poker, a single-player game seen in casinos much like a slot machine, or to other games that use poker hand rankings. Poker is played in a multitude of variations, but most follow the same basic pattern of play. The right to deal each hand typically rotates among the players and is marked by a token called a 'dealer' button or buck. In a casino a house dealer handles the cards for each hand, but a button (typically a white plastic disk) is rotated clockwise among the players to indicate a nominal dealer to determine the order of betting. For each hand, one or more players are required to make forced bets to create an initial stake for which the players will contest. The dealer shuffles the cards, he cuts, and the appropriate number of cards are dealt to the players one at a time. Cards may be dealt either face-up or face-down, depending on the variant of poker being played. After the initial deal, the first of what may be several betting rounds begins. Between rounds, the players' hands develop in some way, often by being dealt additional cards or replacing cards previously dealt. At the end of each round, all bets are gathered into the central pot.

Solitaire or Patience is any of a family of single-player card games of a generally similar character, but varying greatly in detail. The games are generally referred to as "Patience" in British English while "solitaire" is the American English term. These games typically involve dealing cards from a shuffled deck into a prescribed arrangement on a tabletop, from which the player attempts to reorder the deck by suit and rank through a series of moves transferring cards from one place to another under prescribed restrictions. Some games allow for the reshuffling of the deck(s), and/or the placement of cards into new or 'empty' locations. There are many different solitaire games, but the term "solitaire" is often used to refer specifically to the most well-known form, called "Klondike". Klondike and some other solitaire games have been adapted into two-player competitive games. There are a vast array of variations on the solitaire/patience theme, using either one or more decks of cards, with rules of varying complexity and skill levels. Many of these have been converted to electronic form and are available as computer games. Basic forms of Klondike solitaire and FreeCell come with every current installation of Microsoft Windows, for example, and both Windows Me and Windows XP also include a version of Spider. Many software solitaire collections can be downloaded from the internet at no charge.
