How to Form Pure and Impure Sequence? - Rummy Sequence

Introduction

Rummy has been the most popular card game in the Indian subcontinent for generations. Played between two to six players with one or two standard deck of cards (including printed joker cards), the rummy rules are pretty straightforward and easy to comprehend.

In this article, we will learn all about Rummy sequences in Indian Rummy, including the different types, how to form them and how to use them to your advantage. So grab your cards and let's get started!

What is a Sequence in Rummy?

A sequence is a combination of three or more cards of the same suit. Sequences can be either pure (7♠️-8♠️-9♠️) or impure (7♠️-8♠️-Joker).

Understanding Rummy Sequence

A Rummy sequence is the backbone of a successful gameplay strategy. It entails forming a group of three or more cards of the same suit in sequence (e.g. 2♠️-3♠️-4♠️). By mastering the art of creating sequences, you gain a crucial advantage over your opponents. Each sequence you form brings you closer to victory, while the absence of a sequence can lead to a challenging and penalty-ridden journey.

Types of Rummy Sequences

There are two main types of sequences in rummy: pure sequence and impure sequence.

Pure Sequence

A sequence of consecutive cards of the same suit (7♠️-8♠️-9♠️). Joker/wild joker cannot be used to make a pure sequence. One pure sequence is mandatory to win a rummy game. Joker/wild joker cannot be used to make a pure sequence. A wild joker can only be used when it is a part of the suit. E.g: if ‘3’ is a wild joker, you can make a pure sequence with (2♣️-3♣️-4♣️).

Impure Sequence

An impure sequence is a combination of three or more cards where one or more of the sequential cards are replaced by jokers. Both printed jokers and wild jokers can be used to form an impure sequence.

Example:

Let's say you have the following cards in your hand: 5♠-6♠-8♠-9♠ and a Joker. Here, you can use the Joker card to replace the missing 7♠ and form an impure sequence: 5♠-6♠-Joker-8♠-9♠. The Joker card acts as a substitute for the 7♠, allowing you to complete the sequence.

Difference Between Pure and Impure Sequence

Rummy Sequence Rules

To make a valid declaration in rummy, certain rules regarding sequences must be followed:

1. At least two sequences are mandatory, and one of them must be a pure sequence (without jokers).
2. A sequence requires a minimum of three cards.
3. Having no pure sequence results in an invalid declaration with a penalty of 80 points.
4. While creating sets is optional, having at least one pure sequence is mandatory.

How to Create More than One sequence in Rummy?

You can create more than one sequence in rummy depending on the cards you have. It is even possible to arrange all your cards in pure sequences if you have the right cards. Here are a few strategies to consider:

Face Cards Sequence:

If you have face cards (King, Queen, Jack) of the same suit, form a pure sequence with them. They hold higher point values, and creating a sequence with them can minimise your score if your opponent declares before you.

Low Points Cards Sequence:

If you have low-point cards (2, 3 or 4) of the same suit, prioritise creating a pure sequence with them. These cards have lower point values, which can help minimise your score if your opponent declares before you.

High Points Card Sequence:

If you have high-point cards that cannot be used to form a pure sequence, focus on creating impure sequences or sets with them by using jokers.

Valid Declaration

To win at the game of Rummy, players have to make a valid declaration by arranging all the cards in sequences and sets. Any player who makes a valid declaration first wins the game and gets zero points. To make a valid declaration, players need to ensure the following criteria are met:

Pure Sequence: One pure sequence is mandatory to win a rummy game. Joker/wild joker cannot be used to make a pure sequence. A wild joker can only be used when it is a part of the suit. E.g: if ‘3’ is a wild joker, you can make a pure sequence with (2♣️-3♣️-4♣️).

Second Sequence: Two sequences are required in the game of Rummy to make a valid declaration. So, players need to form a second sequence which can be either pure (7♠️-8♠️-9♠️) or impure (7♠️-8♠️-Joker).

Proper Card Arrangement: The rest of the cards need to be arranged in either sequences or sets. Making a set (6♠️, 6♥️, 6♦️) is optional.

Invalid Declaration

If the above criterions are not met, it will result in an invalid declaration. Making an invalid declaration in a 2-player game will result in you losing the game instantly. In games consisting more than 2 players, other players will carry on playing until a valid declaration is made. Here are some examples of invalid declarations:

1. Missing Pure Sequence: A declaration without a pure sequence is invalid.
2. Duplicate Cards: Including duplicate cards within a sequence or set is not allowed. For example, 3♣-3♣-3♠️ is an invalid set as 3 of clubs is present twice.

Always double-check your sequences and sets before making a Rummy declaration.

Strategies for Building Rummy Sequences

Building sequences in rummy requires skill and strategic thinking. Here are some tips to enhance your sequence-building abilities:

Prioritise Pure Sequences: Always aim to create a pure sequence early in the game as it is crucial for a valid declaration.

Observe Discards: Pay close attention to the cards your opponent is discarding. This can give you valuable insights into their hand and help you determine which cards to hold onto or discard to build your sequences.

Strategic Discarding: Be mindful of the cards you discard. Avoid discarding cards that can potentially help your opponents form sequences or sets. Instead, prioritise discarding high-value cards or those that are unlikely to be useful in forming sequences.

Utilise Jokers Wisely: If you have jokers in your hand, use them to create impure sequences or sets.

Common Mistakes to Avoid While Making Sequences

Neglecting Pure Sequences: Don't overlook the significance of having at least one pure sequence. Failing to do so will result in an invalid declaration and a 80 point penalty.

Over-reliance on Jokers: While jokers can be helpful in forming sequences and sets, relying too heavily on them can limit your options and make it challenging to create multiple sequences.

Ignoring Opponents' Moves: Neglecting to observe your opponents' discarded cards can put you at a disadvantage. Stay vigilant and adjust your strategies accordingly.

Failing to Plan Ahead: Effective sequence-building requires planning ahead. Anticipate the possible combinations you can create with the cards in your hand and make informed decisions accordingly.
