This specific variation of rummy incorporates special cards that can substitute for other cards during melds. The utilization of these cards adds a layer of complexity and strategic depth to the traditional game. For instance, if a player lacks a particular card to complete a sequence, the special card can be used in its place, allowing for greater flexibility in forming sets and runs.
The inclusion of substitute cards significantly alters gameplay dynamics. It increases the likelihood of completing melds and potentially speeds up the overall game. Understanding the strategic value of these cards is essential for success. Historically, such additions to card games have aimed to increase player engagement and offer new challenges within a familiar framework.
