Straight Gin

The purest form: knocking is not allowed, so you must reduce your hand all the way to gin to end the round. It rewards patience and clean melding and punishes hoarding high cards. You can play Straight Gin here.

Oklahoma Gin

Identical to standard Gin, except the value of the first upcard sets the maximum deadwood you may knock with. Turn up a five and you can only knock at five or fewer; turn up an ace and it is effectively straight gin for that hand. If the upcard is a spade, the hand scores double. You can play Oklahoma Gin here.

Hollywood Gin

A scoring format rather than a rules change: you keep three games running at once. Your first win is recorded in game one; your second counts in games one and two; your third in all three. It stretches a session into a best-of-three-columns match.

Mahjong Gin

Similar to Straight Gin, but you may take several cards from the discard pile at once, provided you use the lowest of them in a meld immediately. Opponents can also add to melds, giving the game a looser, more tactical feel.

Tedesco Gin

A richer variant where aces can be high or low and runs may go "around the corner" (Q-K-A-2). It uses Hollywood-style scoring with bonuses, and is popular with players who want more melding possibilities.

Single Match and Multi-Match

These are session formats: Single Match plays rounds until a player reaches a target (often 100 points), while Multi-Match strings several matches together. They shape how long you play rather than how a hand works.

Prefer to lay melds on the table instead of holding them? Try classic Rummy or 500 Rum — both playable here — and see the main Gin Rummy guide for the standard rules.
