Knife Duels codes SEASON4, HALLOWEEN, and GRAVEYARD each give you 3,000 Coins, for 9,000 Coins across all three rewards. In this Roblox knife-fighting game, those Coins buy Knife Cases and the skins inside them. To claim your rewards, finish the tutorial, reach level 10, and visit the large Gift Box in the lobby. Each code pays enough for three Butterfly Case openings or two Summer Case openings with 400 Coins left over. Below, you'll find the active codes, redemption instructions, and case rewards worth checking before you spend.
Which Knife Duels codes are active?
The following Knife Duels codes are active as of November 1, 2026. Each code can be redeemed once per account.
| Code | Reward |
|---|---|
| SEASON4 | 3,000 Coins |
| HALLOWEEN | 3,000 Coins |
| GRAVEYARD | 3,000 Coins |
| Total across all three | 9,000 Coins |
SEASON4 is the newest addition to this set. Codes can stop working after updates or events, so claim the rewards before heading into your next match.
How do you redeem Knife Duels codes?
Knife Duels puts code redemption at a physical Gift Box rather than a permanent codes button. Once you're in the main lobby, come down the ramp and look to your right for the large red present.
Follow these steps to claim your Coins:
- Open Knife Duels by KNIFE DUELS Team in Roblox.
- Complete the tutorial and reach level 10.
- Approach the large red Gift Box on the right side of the lobby.
- Hold E near the present to open the Codes tab.
- Paste one active code into the Enter codes here field.
- Select Redeem and check that your Coins have increased.
- Repeat the process for the other active codes.
Redeem each code individually
Keep the code text exact. SEASON4 contains a digit, and all three active codes use capital letters. Copying and pasting avoids most typing mistakes, but check that you haven't included a space before or after the code.
If you also collect rewards in other duel games, the Murder Duels codes guide covers Coins and Recruit Cases for that game.
What should you buy with your free Coins?
Coins pay for normal and seasonal Knife Cases. The Butterfly Case costs 1,000 Coins, while the Summer Case costs 1,300 Coins. That price difference changes how many openings you get out of each code.
| Case | Cost per opening | Openings with 3,000 Coins | Coins remaining |
|---|---|---|---|
| Butterfly Case | 1,000 Coins | 3 | 0 |
| Summer Case | 1,300 Coins | 2 | 400 |
Redeeming all three active codes gives you enough for nine Butterfly Cases. Spending the same 9,000 Coins entirely on Summer Cases buys six openings and leaves 1,200 Coins.
Is the Butterfly Case the better choice?
Choose the Butterfly Case if your priority is more openings. Its lower price stretches your code rewards further, and its reward pool includes these skins:
- Arctic Kukri, Hypergreen Skeleton, and Trance Karambit: 23% each.
- Cobalt M9 Bayonet, Redline Butterfly, and Urban Skeleton: 8.8% each.
- Cosmic Karambit: 5.1%.
- Case Hardened Kukri and Iridescent Butterfly: 0.31% each.
- Special Knife: 0.01%.
The Butterfly Case makes sense when you want more chances to add skins to your collection. If you're chasing a particular knife, check that knife's case pool before buying.
When should you choose the Summer Case?
Pick the Summer Case for its specific skins. It costs 300 Coins more per opening than the Butterfly Case, with rewards including:
- Flamingo M9 Bayonet: 34%.
- Coral M9 Bayonet, Lagoon Karambit, and Surfboard Skeleton: 8.8% each.
- Lime Skeleton and Mango Karambit: 0.31% each.
- Special Knife: 0.01%.
Can you earn Coins without codes?
Winning rounds also earns Coins in Knife Duels. Matches support 1v1 through 4v4, with the first side to reach six wins taking the match. Once you've claimed the single-use codes, round wins give you another way to build your case budget.
Why isn't a Knife Duels code working?
Check the code text and your redemption history before assuming the code has expired. HALLOWEEN, for example, must be entered exactly, and it won't award another 3,000 Coins if you've already redeemed it.
| Possible problem | What to check |
|---|---|
| Incorrect capitalization or extra spaces | Copy the complete code and remove spaces at either end. |
| Code already redeemed | Each code can only reward your account once. |
| Tutorial or level requirement unfinished | Complete the tutorial, reach level 10, and return to the lobby Gift Box. |
| Wrong game | Check that you're playing Knife Duels by KNIFE DUELS Team. |
| Newly released code rejected | Leave and join another server before trying again. |
| Code expired | Use a code from the active table instead. |
The Redeem button is only the submission step. Check your Coins afterward so you know whether the reward was actually added before moving on to the next code.

Where can you find new Knife Duels codes?
New Knife Duels codes usually arrive around updates, events, and milestones. Check the game's Roblox page, the KNIFE DUELS Team Roblox community, and the official Discord linked from the game page for announcements.
When another code arrives, return to the lobby Gift Box, enter it exactly, and check your Coins after selecting Redeem. Codes can be disabled without warning, so claiming a reward promptly is safer than saving the code for a later session.
