Traditional multi-player card games for which rules are available from this site are listed below in alphabetical order, together with the number of players needed.
Some games appear more than once under various names.
Some of the links lead eventually to rules of games held on other sites. Building this site is a long project. At present the site contains rules for only a minority of the card games that exist. Therefore it is quite likely that the game you want is not yet here. If you already know the game you might consider contributing a description of it to this site.
