13 card rummy rules

13-card rummy is a variant in which each player is dealt 13 cards and must arrange them into valid sequences (consecutive same-suit cards) and sets (same rank, different suits) to win.

Hand size
13 cards per player
Valid melds
Sequences of 3+ consecutive cards of the same suit; sets of 3 cards of the same rank in different suits
Winning condition
At least two sequences, one of which must be a pure sequence (no joker) 12
Card values
A, K, Q, J, 10 = 10 points; 2–9 = face value; jokers = 0 12

Key points

  • Players draw and discard to rearrange their 13-card hand into valid melds; the first to fully meld wins.
  • A pure sequence (no joker) is mandatory in Indian Rummy; without it a declaration is invalid.
  • The game works for 2, 3, or 4 players; the 13-card deal is the same regardless of player count.
  • Scoring is based on unmelded cards: high cards (A, K, Q, J, 10) cost 10 points each, number cards cost their face value, and jokers score 0.
