Understanding Rummy: A Complete Guide For centuries, players all over the world have been enthralled with the popular card game rummy. Forming sets and runs from a standard deck of cards is the fundamental aspect of the gramy gameame.

Rummy's straightforward rules make it playable by players of all ages, but even experienced players can be kept interested by the complexity of the strategy required.
