Rummy is a game where winning is mostly dependent on your ability to form strong melds and sets. Groups of three or four cards of the same rankrummy glod are called sets, while combinations of three or more cards of the same rank or consecutive cards of the same suit are called melds. You can lower your hand size & place your cards on the table by forming melds & sets, which will get you closer to calling "Rummy" and winning the round.
