Gin Rummy: what to know before playing
Look at the complete hand before deciding. Build sets and same-suit runs in a ten-card hand, then knock with 10 or fewer deadwood points or go Gin with none. Check the relevant controls before continuing. For a calm first round, focus on one decision. The game uses a single 52-card deck with no jokers. Both players receive 10 cards. Aces are low and count 1. The same rule applies on a phone and on a computer.
Two-player game against a computer. Fixed house scoring: 25-point Gin and undercut bonuses; first to 100, no line/game bonus. The starting player alternates each hand. Big Gin is not included. Current hands save locally.
Give this approach a try
A clear plan starts with the current position. The starting player may take the upcard or pass. If both players pass, the starter must draw from the stock. Check the relevant controls before continuing.
Aim for this result
Build sets and same-suit runs in a ten-card hand, then knock with 10 or fewer deadwood points or go Gin with none. Take the next action only when the current step is clear. For a calm first round, focus on one decision.
Follow these playing steps
- The game uses a single 52-card deck with no jokers. Both players receive 10 cards. Aces are low and count 1.
- The starting player may take the upcard or pass. If both players pass, the starter must draw from the stock.
- Draw one card, then select a different discard when you took from the discard pile. Melds stay in your hand during play.
- Choose Knock / Gin with a selected discard. After discarding, deadwood must be 10 or less. Otherwise continue playing.
- Against a knock, the defender may group cards and lay off unmatched cards on the knocker’s melds. No layoffs are allowed against Gin.
- Gin earns 25 plus defender deadwood. A successful knock earns the difference. A defender with an equal or lower count undercuts for 25 plus the difference.
- The first player to reach 100 points wins this match. There are no additional line or end-of-match bonuses. A stock reduced to two cards ends a non-knocking hand with no score.
Getting comfortable with the controls
Tap a card to select it. Use the labelled pile and action buttons. Sort by rank or suit; the hand wraps onto additional rows on a phone. Use another round to revisit a decision. Use the rule sheet as a reference.
One way to understand the rules
A knocker with 8 deadwood against a defender with 5 after layoffs is undercut: the defender scores 25 + 8 − 5 = 28. Check the relevant controls before continuing.
A mistake to avoid
Treat this as a chance to practise one rule. Q–K–A is not a Gin run: Aces are low. A defender cannot lay off against Gin, and a picked-up discard cannot be returned on the same turn. Return to the explanation when a decision is unclear.

How much is an Ace?
An Ace is worth 1 and only starts a run: A–2–3 is valid, Q–K–A is not. For a calm first round, focus on one decision. The same rule applies on a phone and on a computer.
What happens on a deadwood tie?
Unless the knocker went Gin, a tie is an undercut; the defender scores the 25-point bonus. Keep the active rule in mind. Return to the explanation when a decision is unclear.
Are layoffs automatic?
Yes. The result searches the defender’s legal groups and possible extensions to find the least remaining deadwood. For a calm first round, focus on one decision. Return to the explanation when a decision is unclear.
Can a hand end without a winner?
Yes. When the stock is reduced to two and the active player ends the turn without knocking, the hand has no score. Before making a move, check the cards in view. Use another round to revisit a decision.
