What Is a Pure Sequence in Rummy? Rules, Examples and Mistakes

In 13-card Indian rummy, a winning declaration needs all 13 cards arranged into valid groups, and among them at least two sequences, at least one of which is pure. If you declare without a pure sequence, the declaration is invalid, however good the rest of your hand looks, and under common rules you're charged the maximum penalty (usually 80 points).

The pure sequence also matters when someone else declares. Under the usual rules, if you haven't completed a pure sequence, every card in your hand is counted against you, up to the cap. That's why experienced players build the pure sequence first.

If you searched for the pure sequence in Teen Patti or 3 Patti, the idea is the same (consecutive cards of one suit) but its job is different. In Teen Patti you only hold three cards, so a pure sequence is exactly three consecutive cards of the same suit, such as 5♥ 6♥ 7♥. It isn't a requirement for anything: it's a hand, and the second-strongest one, beaten only by a Trail (three of a kind).

For the full Teen Patti order, from Trail down to High Card with the odds of each, see our Teen Patti sequence list and chart.

A pure sequence is a run of three or more cards that are consecutive in rank and all of the same suit, with no joker standing in for a missing card. Longer runs are fine.

A pure sequence uses only the real cards in their real places; an impure sequence uses at least one joker as a stand-in. 3♠ 4♠ 5♠ is pure; 3♠ Joker 5♠ is impure. Both count as sequences, but only a pure one satisfies the must-have rule.

• Sort your 13 cards by suit as soon as they're dealt, and look for two or three cards that are already consecutive in one suit.
• Keep connected cards (6♥ 7♥) and cards one gap apart (6♥ 8♥) in the same suit; they're your best pure-sequence chances.
• Don't spend a joker on your first sequence. Jokers are most valuable completing your second sequence or a set.
• Discard high-value cards (Aces and face cards are worth 10 points each) early if they don't fit, so they can't hurt you if someone declares.
• Once the pure sequence is down, a joker can complete almost anything else, so your hand becomes much easier to finish.

Pure sequences are one part of the game. For the full rules, see how to play Indian rummy and the rummy game guide. For what an unfinished hand costs you, see rummy points calculation.

A set can't contain two cards of the same suit: Q♥ Q♥ Q♣ (possible with two decks) is not a valid set.

There's no fixed maximum beyond the cards you hold: three, four, five or more consecutive cards of one suit are all one pure sequence. Long runs can be handy because you can split them: a 6-card run such as 3♥ to 8♥ can become two 3-card pure sequences if that helps finish your hand. Remember that the whole hand still needs at least two sequences, at least one of them pure.

With two decks in play, there are two copies of each card, so a connected pair has up to four cards that can complete it.

• Using a joker in the first sequence, then having nothing left to complete the second.
• Holding onto high cards for a pure sequence that never arrives, and paying 10 points each when someone declares.
• Forgetting that the second sequence is also required: one pure sequence plus sets is not a valid declaration.
• Declaring in a hurry and misreading a mixed-suit run as pure.
