Monitoring the cards that have been played, those that remain in the draw pile, and the cards in other players' hands is the process of card counting. Players are then betterrummyearn equipped to decide which cards to discard or pick up, as well as which sets or sequences have the highest chance of being completed. Participants can learn important information about which cards are safe to pick up and which are probably going to be needed by other players by keeping a close eye on the cards that their opponents have discarded.
