Take a closer look while playing
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. The same rule applies on a phone and on a computer.
The objective of a round
Build sets and same-suit runs in a ten-card hand, then knock with 10 or fewer deadwood points or go Gin with none. Use another round to revisit a decision. Work at your own pace.
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.
How your actions work
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. The same rule applies on a phone and on a computer. For a calm first round, focus on one decision.
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. Take the next action only when the current step is clear.
Pay attention to this rule
Keep the active rule in mind. 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. Take the next action only when the current step is clear.

Can you give an example?
A knocker with 8 deadwood against a defender with 5 after layoffs is undercut: the defender scores 25 + 8 − 5 = 28. A clear plan starts with the current position. Take the next action only when the current step is clear.
When may I knock?
After drawing, select the card you would discard. The remaining 10 cards must have no more than 10 deadwood points. Work at your own pace. The same rule applies on a phone and on a computer.
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. Treat this as a chance to practise one rule. 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. A clear plan starts with the current position. Use another round to revisit a decision.
Are layoffs automatic?
Yes. The result searches the defender’s legal groups and possible extensions to find the least remaining deadwood. Look at the complete hand before deciding. 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. Use the rule sheet as a reference. Take the next action only when the current step is clear.
