While the goal of Gin Rummy is to form sets and runs of cards in the hand, Indian Rummy necessitates that players form at least two sequences, one of which must be a purrummy devtae sequence devoid of jokers. A scoring system is incorporated into Rummy 500, wherein players receive points for merging cards. The game of rummy requires agility, thinking, & recall. To effectively form their own sets and sequences, players must continue to pay attention to the cards that their opponents are choosing to discard & mix.
