How to Calculate Deadwood in Gin Rummy
Deadwood is the total point value of all cards in your hand that are not part of a valid meld. Deadwood calculation determines whether you can knock, how many points are scored after a knock, and whether you’re at risk of being undercut.
Card Values for Deadwood
| Card | Deadwood Value |
|---|---|
| Ace (A) | 1 point |
| 2 | 2 points |
| 3 | 3 points |
| 4 | 4 points |
| 5 | 5 points |
| 6 | 6 points |
| 7 | 7 points |
| 8 | 8 points |
| 9 | 9 points |
| 10 | 10 points |
| Jack (J) | 10 points |
| Queen (Q) | 10 points |
| King (K) | 10 points |
Key facts:
- Face cards (J, Q, K) all count as 10 points each — same as the 10 card.
- Aces are always 1 point — not 11. Never high.
- Only unmatched cards count as deadwood. Cards in valid melds count as 0 deadwood.
Step-by-Step Deadwood Calculation
Step 1: Identify Your Best Meld Arrangement
Before counting deadwood, find the card arrangement that minimizes your deadwood. This means identifying all valid sets and runs, then choosing the combination that leaves the fewest points unaccounted for.
A card can only belong to one meld — not two simultaneously. So if the same card could complete two different partial melds, you must choose which meld to place it in.
Step 2: Separate Melds from Deadwood
Physically or mentally separate:
- Meld group: Cards in confirmed sets and runs (count as 0 deadwood)
- Deadwood group: All remaining unmatched cards
Step 3: Add Up Deadwood Card Values
Sum the point values of every card in the deadwood group using the table above.
Example Hands
Example 1: Simple Calculation
Hand: 8♠ 8♥ 8♦ | Q♣ J♣ 10♣ | K♦ 5♥ 3♠ 2♣
- Meld 1: 8♠ 8♥ 8♦ (three of a kind — set)
- Meld 2: Q♣ J♣ 10♣ (run in clubs)
- Deadwood: K♦ (10) + 5♥ (5) + 3♠ (3) + 2♣ (2) = 20 deadwood
This hand cannot knock (20 > 10) but is close. Dropping the K♦ and drawing something low would be the priority.
Example 2: Borderline Knock
Hand: 7♥ 8♥ 9♥ | A♠ A♦ A♣ | 4♦ 3♦ 2♦ | 10♠
- Meld 1: 7♥ 8♥ 9♥ (run)
- Meld 2: A♠ A♦ A♣ (set)
- Meld 3: 4♦ 3♦ 2♦ (run)
- Deadwood: 10♠ = 10 deadwood
This hand is eligible to knock — exactly at the 10-point threshold.
Example 3: Overlapping Meld Choices
Hand: 5♣ 5♦ 5♥ 6♥ 7♥ | K♠ K♦ | 9♣ 4♠ 2♠
Notice that 5♥ could go into:
- The 5♣ 5♦ 5♥ set, OR
- A run with 6♥ 7♥ (as 5♥ 6♥ 7♥)
Option A — Use 5♥ in the set:
- Melds: 5♣ 5♦ 5♥ (set) | 6♥ 7♥ (partial — not a meld, only 2 cards)
- Deadwood: 6♥ (6) + 7♥ (7) + K♠ (10) + K♦ (10) + 9♣ (9) + 4♠ (4) + 2♠ (2) = 48
Option B — Use 5♥ in the run:
- Melds: 5♥ 6♥ 7♥ (run) | 5♣ 5♦ (partial — not a meld, only 2 cards)
- Deadwood: 5♣ (5) + 5♦ (5) + K♠ (10) + K♦ (10) + 9♣ (9) + 4♠ (4) + 2♠ (2) = 45
Best choice: Option B — 45 deadwood vs. 48 deadwood.
Always check overlapping card assignments to find the minimum deadwood arrangement.
Deadwood and Knock Eligibility
You may knock if your deadwood total is 10 or fewer. This is the standard threshold — exactly 10 qualifies.
| Deadwood | Knock Eligible? |
|---|---|
| 0 | Yes (also qualifies for Gin) |
| 1–9 | Yes |
| 10 | Yes |
| 11+ | No |
In Oklahoma Gin, the threshold changes per hand based on the upcard.
Minimizing Deadwood: Practical Tips
1. Prioritize high-value deadwood reduction first. A King, Queen, or Jack costs 10 points each. Discarding a King vs. discarding a 2 saves 8 points. Early in the hand, shed face cards that don’t fit melds.
2. Look for dual-purpose cards. Some cards can fit two different partial melds. Hold them longer because they have more meld-forming potential per card.
3. Count before you knock. Always verify your deadwood count before knocking — miscounting is a common mistake that can cost a hand.
4. Consider laying-off vulnerability. When you knock, you expose your melds. Low deadwood protects against undercuts; high deadwood (8–10) is a riskier knock.
Scoring With Deadwood After a Knock
When a hand ends by knock, the deadwood difference is scored:
Knocker’s score = Opponent’s deadwood − Knocker’s deadwood (when knocker wins)
After the lay-off phase, any remaining deadwood the opponent holds is compared to the knocker’s deadwood.
