Invented Card Games This section of the card games site is devoted to new games played with existing cards. The idea is to provide a forum for card game inventors to publish their ideas, and to try out and comment on each other's games. Traditional card games will not be found here, but in the main body of the site (see for example the alphabetical index). Most of the games on this page have been contributed by their inventors. If you would like to contribute a game of your own to this page, or publish a comment, variation or improvement on one of the games here, you can send me your contribution by e-mail. The games are at present listed in alphabetical order (with numbers at the end). Aardvark Game [archive copy] A game for friends, created by James Quin, Adam Tilghman, Luke Weisman and Renée Sharp. Abracadabra A trick-taking game with exact bidding game by Paul Newton, in which players not only predict how many tricks they will win, but also which ones.
