The core of Ek Rummy is forming melds and sets, and a player's chances of winning can be greatly increased by becoming proficient in this area of the game. It's critical to all.rummyknow which cards to keep and which to discard in a meld, which can be either a set or a sequence. A player is just one card away from finishing a set, for example, if they have two cards of the same rank but different suits. On the other hand, they are approaching the formation of a sequence if they have three cards in a row of the same suit.
