Pure and impure run validator

Rummy Sequence Checker

Test three or more cards to see whether they form a pure sequence, an impure sequence, or neither.

Separate cards with spaces or commas. Cards can be entered in any order.
AS = A♠10H = 10♥QD = Q♦7C = 7♣PJ = Joker
A printed joker uses the code PJ. The selected rank can substitute for a missing card.

Ready to check

Try the sample: the printed joker completes 8♥–9♥–10♥–J♥.

Ace can be low in A-2-3 or high in Q-K-A, but it cannot wrap around in K-A-2.
