Throughout the Rummy game, paying close attention to your opponents can yield insightful information that helps you adjust your strategy. Players can learn about the hands & possible melds of their opponents by keeping an eye on thteen patae cards they draw and discard. When an opponent routinely selects particular suits or ranks from the discard pile, for instance, it could be a sign that they want to form particular sets or runs. With this information, you can modify your own play appropriately, maybe by not discarding cards that would enable them to finish their melds. Also, observing the habits and behaviors of opponents can also highlight trends that could be used against you in the game.
