When it comes to Rummy, the discard pile is a gold mine of information that can significantly impact your strategy. By keeping track of which cards have been thrown away, you can decide which ones to keeppg slots in your hand and which to draw from the pile with greater knowledge. If you see, for example, that a number of high-value cards have already been discarded, it might mean that those cards are less likely to help you or your opponents in subsequent turns. This knowledge can assist you in deciding which cards should be kept and which can be safely thrown away without endangering your ability to form melds.
