Rummy is a group of matching-card games notable for similar gameplay based on matching cards of the same rank or sequence and same suit. The basic goal in any form of rummy is to build melds which can be either sets (three or four of a kind of the same rank) or runs (three or more sequential cards of the same suit) and either be first to go out or to amass more points than the opposition.

Denna implementation inkluderar 500 rummy (eller 500 rum) och vanlig rummy, vilket är två av de populäraste rummy spelen.
