Straight Gin is Gin Rummy stripped to its core: knocking is not allowed, so the only way to end a hand is to go gin — meld all ten cards.
How Straight Gin works
Everything is standard Gin Rummy — ten-card hands, draw and discard, sets and runs — except you can never knock on a small deadwood total. Play continues until one player melds their whole hand and goes gin, taking the opponent's deadwood plus the gin bonus.
Straight Gin strategy
Favour cards with the most connections and shed isolated high cards early — they are dead weight you can never knock away. Since both players chase gin, do not feed the discard pile cards your opponent obviously needs.
