What Is Knock Rummy?
Knock Rummy is a variant of Gin Rummy that works for 2–6 players. Instead of waiting to go Gin, any player can end the hand at any time by knocking — placing a card face-down as a discard and revealing their hand. If your unmelded cards (deadwood) are lower than all opponents’, you win. If anyone matches or beats you, you pay a penalty.
What You Need
- A standard 52-card deck
- 2 to 6 players
- Score pad or chips
Setup
- For 2 players: deal 10 cards each. For 3–5 players: deal 7 cards each. For 6 players: deal 6 cards each.
- Remaining deck = stock. Flip top card = discard pile start.
How to Play
- On your turn: draw from stock or top of discard pile.
- Arrange your hand into melds (sets of 3–4 same rank, runs of 3+ same suit).
- Discard 1 card OR knock.
How to Knock
- Discard your card face-DOWN (signal that you’re knocking).
- Reveal your full hand, organized into melds and deadwood (unmelded cards).
- All opponents reveal their hands.
- Opponents may lay off their unmelded cards onto YOUR melds to reduce their deadwood.
- Count deadwood values: A=1, face cards=10, others=face value.
Knock Outcomes
- Knocker has lowest deadwood: Win the difference between your deadwood and each opponent’s deadwood.
- Another player equals or beats the knocker’s deadwood: Knocker pays a penalty (usually 10 pts or 2× the difference).
- Going Gin (0 deadwood before knocking): Bonus points — opponents cannot lay off.
Scoring
Track points won/lost. In chip games, settle after each hand. In score games, play to 100 or 500 points.
Strategy Tips
- Knock early at 10 or fewer deadwood — waiting risks another player going Gin.
- Watch what opponents draw — if someone takes from the discard frequently, they’re close to melding.
- Going Gin is risky but rewarding — you prevent lay-offs and earn a bonus.
