Indian Rummy and Mathematics Go Hand-in-hand. Here’s How!

Do you ever wonder how the pyramids were made? Or how the suspension bridges never fall? Or have you ever wondered how cards were numbered? Well, the answer to these questions is largely based on mathematical calculations. Mathematics is a universal language and its usage can be seen almost everywhere. Even card games such as Indian rummy can be won using basic mathematical skills.

Online rummy is a simple card game that requires a fair amount of skills to win. When the cards are dealt, players must know how to analyze their cards, plan their strategies and calculate their probability of winning the game. Let us learn a few basics of how to play rummy before we understand its mathematical connection.

The basics of Indian rummy

Rummy is a sorting and matching game played by two to six players at a time. The number of card decks used in this game can be either one or two, depending on the number of players playing. Each player is dealt 13 cards and the remaining cards form the closed and open piles, which are kept at the center of the table.

When the game begins, the first player picks a card from the closed pile and discards an unwanted card from his/her hand into the open pile. The objective of this game is to arrange all 13 cards in hand into viable combinations and make a valid declaration. The cards can be arranged into sequences or sequences and sets. 

The player who makes a valid declaration before anyone else at the table wins the game. The winner gets zero points and the losing players incur penalty points, which are calculated on the basis of ungrouped cards in their hand.

Rummy and probability

Now that you know the basics of rummy, you may be wondering how mathematics can be used while playing this game. Well, probability can help you identify your chances of winning the game.

We all know that a standard card deck consists of 52 cards, which can be divided into 4 suits (hearts, diamonds, spades, and clubs) of 13 cards each. Each suit consists of an ace (A), nine numbered cards from 2 to 10, and three face cards (K, Q, and J). 

In mathematical terms, the probability of picking a favorable card is (1/52).

In the same way, the probability of not picking a favorable card is (1-1/52) = (51/52).

So you can see that the probability of getting the desired card is very low. Moreover, it can be said that the role of chance in rummy card games is next to zero. So you have to win the game on the basis of your skills and experience.

Rummy and basic math calculation

Addition and subtraction are basic mathematical skills that are taught during early schooling years. In rummy games, you can use your calculation skills to count the points in your hand. 

Suppose you are dealt the following hand. 

3♠-4♠-5♠ | K♠-K♣-K♥-K♦ | 5♦ 10♥ | A♣ 2♥ 8♣ 9♠

This hand has a pre-made pure sequence (3♠-4♠-5♠) and a set (K♠-K♣-K♥-K♦). 

You can calculate the points of the remaining cards as follows:

5 (5♦) + 10 (10♥) + 10 (A♣) + 2 (2♥) + 8 (8♣) + 9 (9♠) = 44 points.

The point load in your hand is 44. You need two more combinations to reduce the point load to zero. In this way, you can calculate the points in your hand and keep a track of your game.

If you are good at math, you have a better chance of winning rummy games. Moreover, we also advise you to play practice games to brush up on your skills.
