Three or four cards of the same rank but different suits make up a set, whereas three or more cards of the same suit in a row make up a sequence. The use of wild carrummy daily apkds, which can substitute any card to form sets or sequences, is one of Rummy Dragon's unique features. Given that players must choose when to use their wild cards for the greatest benefit, this feature gives the game a strategic element. After drawing a card from the discard pile or the stockpile, each player discards one card.
