One of the most underappreciated aspects of Rummy Go is watching your opponents' moves, which can reveal important information about their plans and strategies. You can learn more about their hand composition and possiking of slotsble melds they are attempting to form by observing the cards they draw and discard. With this information at your disposal, you can decide which cards to keep & which to throw away. Also, monitoring the cards that your opponents have discarded can help you predict their next moves. An opponent may be having difficulties with their hand if you observe that they have discarded a number of high-value cards without creating any melds.
