It is important for players to constantly consider which cards they are discarding and how those cards could help others. Keeping track of which cards are still in the deck and which have already been played is a useful discarding technique. This information enables playrummy estaers to decide what to discard with knowledge. For instance, since opponents are less likely to pick up higher-value cards when trying to form melds, it might be a good idea to hold onto them if you see that a number of low-value cards have already been played. Also, it can be a calculated move that keeps you ahead of the game to discard cards that are less likely to aid your opponents—for example, cards that don't fit into their obvious melds. In Game 51, jokers are wild cards that give the gameplay an exciting new level of complexity.
