Each player has a hand of cards and a move consists of exchanging a card or cards. The exchange may be with another player or with a stock of face-up or face-down cards on the table. The objective is generally to collect certain cards or combinations of cards.
Card exchange games are subdivided in different subfamilies:
Draw and Discard Games
The basic move is to draw a card from the stock and discard one to the discard pile. This category includes the large group of Rummy Games.
There is a common pool of cards on the table, and at your turn you exchange one or more cards with the pool.
Each player has only one card, and at their turn can try to exchange this for their neighbour's card.
At your turn you can ask another player for a card that you want, and if they have it they must give it to you.
Card passing games
A move consists of passing a card or cards to your neighbour, or in some cases taking a card from your neighbour.
