Pure Sequence
Pure Sequence meaning in Yono Rummy
A pure sequence is three or more consecutive cards of the same suit, made without using a joker as a substitute.
Short answer: 5♥–6♥–7♥ is pure. 5♥–Joker–7♥ is not pure because the joker replaces the missing 6♥. In standard 13-card Indian Rummy, a valid declaration needs at least one pure sequence and a second sequence.
Table flow reminder
Valid and invalid examples
Consecutive ranks, one suit, no substitute joker.
Four consecutive clubs also make one pure sequence.
This can be an impure sequence, but it cannot satisfy the pure-sequence requirement.
Next, compare pure vs impure sequence, check how a joker works in a sequence, then use the valid declaration checklist.
