# Here’s How a Rummy Game Creates a Bonding with Mathematics

Rummy is a card matching game that originated decades ago but continues to retain its popularity evenin the age of digitalization. There are several websites offering free rummy games. One may play the rummy card gameeither offline or online. However, the game is fun either ways. It is also related to mathematics. Rummy card game is such an interesting game that even people who hated mathematics classes at school would love to play the game with much interest, unknowingly using the math concepts of the game. As the game involves the melding of cards into sets and sequences, it involves the use of the principles of probability, permutation and combination etc.

The concept of Probability in Rummy card game

Rummy is a skill based game which can be discussed in the light of the principles of probability. There are 52 cards in a deck, 13 each from each suit; out of which four face cards conversely belong to each suit. While you play rummy online or offline, you need to meld cards according to sets and sequences. So, the probability of picking a favourable card out of this deck = (1/52)

Thus, probability of picking up an unfavourable card = (1-1/52) =51/52

Despite the probability of picking up a favorable card is far less than that of picking an unfavorable card, one can succeed at rummy card game with the help of one’s skill. There are factors that aid your skill. Use of more than one deck gives better chances of getting a favorable card. The course of the game can be changed by the pick and drop of cards by the players. Another trick that can significantly enhance the chances of winning at rummy is that a player can anticipate the probable cards at hand with the opponent by keeping a keen watch on the cards discarded by him.Predicting the cards of opponent can influence your decision of picking or discarding specific cards in the course of the game. Each of these factors is related with probability and skill; thus, proves crucial for winning at rummy. Developing these skills by practicing provides a greater chance to win at rummy card game.

The Concept of Permutation and Combination

Another mathematical concept that plays a role in rummy is permutation and combination. Permutation and combination involves a complex formula that suggests the possibilities of sequence needed to form a meld. The basic algorithm of permutation and combination is as follows.

NPR = N!/(N – R)!

Where Number of all permutations of N things, taken R at a time.

It is quite amusing how every good rummy player uses this complex formula in their head whilst playing rummy.They can use it within the shortest time provided during their turn while they play rummy online.

As rummy is a skill based game, it may be a bit difficult at first for those who are unfamiliar with these mathematical concepts. However, if one plays several free rummy games, it would not take much time to master the skills. One may play online rummy game anytime and anywhere. The rummy card game is extremely interesting if played with a good knowledge of mathematics, and a better understanding of its relation with the card games.
