"Two players were arguing with each other about Rummy. One advocated that 13 Cards Rummy is more exciting than 21 Cards Rummy, while the other defended his claim that 21 Rummy is the best.....”
This debate is interesting but if you were to decide, which game will you pick? Difficult to choose, isn't? But don't worry; let's settle this debate here!
The objective of both 13 Card Rummy and 21 Card Rummy is the same - arrange all the cards in sets and sequences to make a valid hand. However, there are some basic differences which make them unique in their gameplay. Let us view the differences in detail:
As their names suggest, 13 and 21 cards are dealt to each player in 13 Cards Rummy and 21 Cards Rummy respectively. As there are eight cards less in 13 Cards Rummy, it is much faster than 21 cards Rummy.
13 Cards Rummy needs up to 2 decks, while 21 Cards Rummy needs 3 decks of cards in a usual game. The addition of one deck in 21 Cards Rummy makes it more complex as there will be three sets of a single card. So, one would need more strategies in 21 Cards Rummy.
In 13 Cards Rummy, you need to make a minimum of 1 pure sequence along with another sequence to win. However, in 21 Cards Rummy, you need a minimum of 3 pure sequences; this makes 13 Cards Rummy much easier than the 21 card variant.
Jokers play the same role in both the variants, which is to replace any card to form sets or sequences. However, 21 Cards have Value Cards in addition to Jokers: they function as Jokers and carry extra points that could change the game. Plus, a marriage hand of all the value cards makes it more competitive.
