does a run in gin rummy have to be the same suit
The basic game strategy is to improve one's hand by forming melds and eliminating deadwood. Gin has two types of meld: Sets of 3 or 4 cards sharing the same rank, e.g. 8♥ 8 8♠; and runs of 3 or more cards in sequence, of the same suit, such as 3♥ 4♥ 5♥ or more. Deadwood cards are those not in any meld. Aces are considered low--they can form a set with other aces but only the low end of runs (A♠ 2♠ 3♠ is a legal run but Q♠ K♠ A♠ is not). A player can form any combination of melds within their hand, whether it contains all sets, all runs, or a mix of both. A hand can contain three or fewer melds to knock or form legal gin.
