Oklahoma Gin
Oklahoma Gin is the most widely played competitive variation of Gin Rummy. In standard Gin Rummy, a player can always knock when their deadwood is 10 points or fewer. In Oklahoma Gin, the maximum deadwood allowed to knock is determined by the rank of the original upcard (the card turned face up at the start of the deal):
- Face cards (K, Q, J): Count as 10, meaning normal 10-point knock rules apply.
- Number cards (2 through 10): The knock threshold equals the card's numerical value. For example, if the upcard is a 6, you can only knock with 6 or fewer deadwood points.
- Ace: You can only knock with 1 deadwood point (or go Gin).
Spade Doubling Rule: If the original upcard is a Spade, all hand points, undercut bonuses, and gin bonuses earned in that hand are doubled!
Hollywood Gin
Hollywood Gin is a scoring format rather than a rules change. Instead of playing a single match to 100 points, players compete in three simultaneous games on a three-column scoresheet:
- When a player wins their first hand, their points are written only in Game 1.
- When they win their second hand, their points are recorded in both Game 1 and Game 2.
- When they win their third hand (and every subsequent hand), their points are credited to all three games: Game 1, Game 2, and Game 3.
Each column is played to 100 or 150 points. A game column closes when a player reaches the target, and winner/line bonuses are calculated for that game while the remaining games continue.
Straight Gin
In Straight Gin, players are not allowed to knock. The only way to win a hand is to achieve Gin—meaning all 10 cards must be melded with zero deadwood remaining.
- No layoffs: Because there is no knocking, defender layoffs do not exist.
- No undercuts: Since knocking is disallowed, undercuts cannot happen.
- High tension: Hands last longer and stock cards run much deeper, requiring players to continually balance uncompleted combinations.
Other Popular Variations
Tedesco (Jersey Gin)
In Tedesco, Aces can be used high or low in runs (such as A-2-3 or Q-K-A). However, "around-the-corner" runs (like K-A-2) remain illegal. In some circles, an Ace held as deadwood counts as 15 points if caught unmelded.
Match Play with Shutouts (Schneider)
When playing a full match to 100 points, if the loser scored zero points throughout the match, the winner scores a "shutout" (or "schneider"), doubling the match-winner bonus.

Frequently asked questions
What is the difference between Gin Rummy and Oklahoma Gin?
In standard Gin Rummy, you can always knock with 10 deadwood points or fewer. In Oklahoma Gin, the rank of the original upcard determines the maximum deadwood needed to knock (for example, if the upcard is a 6, you must have 6 or fewer deadwood to knock). If the upcard is a spade, hand points and bonuses are doubled.
Can you knock in Straight Gin?
No. In Straight Gin, knocking is not permitted. Players must keep drawing and discarding until one player forms complete melds with zero deadwood (Gin).
How does scoring work in Hollywood Gin?
Hollywood Gin uses three simultaneous game columns on one scoresheet. Your first hand win scores in Game 1 only. Your second win scores in Game 1 and Game 2. Your third and subsequent wins score simultaneously in Games 1, 2, and 3. Each game plays to 100 or 150 points independently.
Are these variations still considered Gin Rummy?
Yes. They all use the same core 10-card hand, drawing, discarding, and set/run meld mechanics, but modify the knocking conditions or match scoring.
