While playing online rummy game the aim is to form sequences and sets or trails.
A sequence is a combination of 3 or more consecutive value cards of the same suit, with the order being Ace-2-3-4-5-6-7-8-9-10-Jack-Queen-King-Ace. When you play rummy online, please note that Ace-2-3 is a sequence like Ace King Queen, but not King Ace 2.
In rummy games, a trail or a set is a combination of at least 3 and a maximum of 4 cards of the same rank but different suits. For instance, 8 of hearts, 8 of spades, and 8 of clubs is a valid set, but 8 of clubs, 8 of spades, and 8 of spades won't make a valid set.
Also, keep in mind not to overlap the sequences when you play rummy. For instance, 3H-4H-5H-5D-5C is either a sequence with two spare 5s or a set of fives with two spare hearts. If a 5H is added or a 2H is added, the cards will form a sequence and a set. One needs to know the rules like the back of their hand to play rummy online.
Joker and wild cards are used as substitutes while playing rummy, where a player can form a sequence or a set when not having the suitable cards. For instance, if the card turned up is 2C, then 9H-2C-JackH is a valid sequence, and KK2 is a valid set.
A straight run is formed without using any jokers or wild cards. At least one straight run is necessary in online rummy for a player to make a valid declaration. For instance, if 2H is a wild card, AceH, 2H, and 3H are still a straight sequence, but KQ2H is a straight run and an ordinary sequence.
As an exception, when three decks are used, an additional type of meld of three identical cards with the same rank and suit are considered equivalent to a pure sequence in online rummy. For instance, KH, KH, KH. This is also known as Tanala.
To declare a hand and win it, you need to hold at least two sequences, and at least one of these sequences should be pure. The first pure sequence is also known as the first life and the following sequence as the second life.
A winning hand in rummy game online can have these four combinations - a set of 4 cards and three sets of 3 cards each or three combinations made of 5 card sequence, a four-card meld, and four card meld or five-card meld, five-card meld, and three-card meld.
