Gin Rummy Variations
Oklahoma Gin
Oklahoma Gin plays exactly like standard Gin Rummy with one change: the first upcard sets the knock limit for the whole hand. Turn up a 5 and nobody may knock with more than 5 deadwood; turn up an ace and most tables require gin itself to end the hand. Face cards and tens keep the familiar limit of 10.
First upcard and the maximum deadwood to knock:
Ace — 1, and many tables play it as gin only
2 through 10 — the pip value of the upcard
Jack, Queen, or King — 10, the standard game
Many tables add a second twist: when the first upcard is a spade, every point scored in that hand is doubled, gin and undercut bonuses included. A doubled hand under a low knock limit is where Oklahoma matches swing hardest.
The variable limit changes strategy more than rules. Under a 3-point limit, high pairs become nearly worthless keepers, undercuts multiply because both players sit on tiny counts, and hands run longer, closer to the gin-only endgame described under Straight Gin below. The game on this site always plays the standard knock-at-10 rules, so treat Oklahoma as a paper-table variant.
Hollywood Gin
Hollywood Gin does not change a single card play — it changes the bookkeeping. The score sheet has three columns, traditionally Game One, Game Two, and Game Three, and each hand you win is entered in more than one of them as the match progresses:
Your first winning hand — scored in Game One only
Your second winning hand — scored in Game One and Game Two
Your third and every later win — scored in all three games
Each column is a full game to 100 with its own bonuses, so one sitting produces three results. Example: you win the first three hands for 18, 25, and 12 points. Game One reads 55, Game Two reads 37, and Game Three reads 12. A cold streak late in the match can cost you two games at once, which is exactly why the variant rewards steady play over one big gin.
Straight Gin
Straight Gin removes knocking entirely: hands continue until one player goes gin, however long that takes. There is no knock decision, no undercut, and usually a larger gin bonus — commonly 50 points instead of 25 — because gin is the only way to score.
Removing the knock rewrites priorities. Deadwood totals stop mattering except when the stock runs out, so a hand of two finished melds and one developing combination beats a cheap hand of scattered low cards. Defense matters more too: with no threat of a quick knock, discards stay dangerous for the whole hand, and high cards are often held longer purely to starve the opponent. If you enjoy the patient endgame that standard gin only occasionally produces, this variant makes it every hand.
Gin Rummy vs Rummy
Gin Rummy and standard Rummy share melds — sets of equal rank, runs in one suit — but they are different games. Gin Rummy is strictly two players with ten-card hands; melds stay hidden until someone knocks or goes gin, and the score comes from the deadwood gap plus bonuses. Standard Rummy commonly seats two to six players with smaller hands; melds are laid face up during play, players extend their own and other players' melds over multiple turns, and a hand ends when someone sheds their last card, scoring the cards still stuck in opposing hands.
The practical difference is information. In Rummy the table shows you most of what is happening; in Gin Rummy nearly everything must be inferred from discards and pickups, which is why discard reading dominates gin strategy.
