Pure Sequence Rule in Rummy 51
Definition of a Pure Sequence
A Pure Sequence (also called a natural run or tierce franche) is a combination of three or more consecutive cards of the exact same suit created without using any Joker.
In Rummy 51, holding a pure sequence in your initial meld is mandatory. Even if your cards total 100 points, your opening laydown will be rejected if it lacks a pure sequence.
