How to Redeem KNIFE DUELS Codes

Promo codes in KNIFE DUELS (Place ID 112731528776884) grant free coins when you redeem them at the physical gift box in the lobby. As of August 2026, four active codes — BUTTERFLY, LOADING, summer, and DYNAMIC — each give 3,000 Coins. See our codes status page for the full list and reward totals.

Redemption is not hidden inside a settings menu. You interact with a present box near the shop after completing the mandatory tutorial. This guide covers PC and mobile steps, plus troubleshooting for the most common failures.

Find the Gift Box Near the Shop

After launching KNIFE DUELS and finishing the tutorial, spawn into the main hub lobby. Walk toward the shop area and look for a gift/present box sitting nearby — this is the code redemption station.

On PC, approach the box and hold E when the interact prompt appears. A code entry panel opens with a text field and a Redeem button. On mobile and tablet, tap the on-screen interact prompt instead of holding a key. This physical object is the only legitimate redemption path — ignore third-party websites that ask for your Roblox password.

Make sure you are in KNIFE DUELS (Place ID 112731528776884), not Knife VS Gun DUELS. The wrong game has a similar name but no gift-box redemption flow for these August 2026 codes.

Step-by-Step Redemption

1. Launch KNIFE DUELS from Roblox and complete the mandatory tutorial. The gift box stays locked until you finish.
2. In the lobby, walk to the present box near the shop.
3. PC: hold E on the gift box. Mobile: tap the interact prompt.
4. Type or paste one active code exactly — codes are case-sensitive:
   • BUTTERFLY → 3,000 Coins
   • LOADING → 3,000 Coins
   • summer → 3,000 Coins (lowercase s)
   • DYNAMIC → 3,000 Coins
5. Press Redeem and wait two to three seconds. Coins update instantly on success.
6. Repeat for each remaining code — one at a time, up to 12,000 Coins total.

After redeeming, browse the in-game shop or use the coin calculator to plan your spending. Read August 2026 update notes for context on the new map where the gift box is located.

Redeeming on Mobile (iOS and Android)

Mobile redemption uses the same gift box — no separate menu. Launch KNIFE DUELS from the Roblox app, finish the tutorial, and walk to the present near the shop. Tap the interact icon when it appears over the box, then paste your code from the clipboard.

Paste carefully on a touchscreen. Accidental spaces before or after the string cause instant failures. Landscape mode on tablets gives a larger view of the code field when the keyboard is open. Rewards bind to your Roblox user ID, so coins redeemed on phone appear on PC sessions too.

Troubleshooting Failed Redemptions

When Redeem fails or shows an error, work through this checklist:

• Case mismatch — summer requires a lowercase s. Summer or SUMMER will fail. BUTTERFLY, LOADING, and DYNAMIC are all uppercase.
• Extra spaces — remove leading or trailing spaces from copy-paste. Type manually if paste keeps failing.
• Already redeemed — each code works once per Roblox account. A second attempt on the same account always fails.
• Tutorial incomplete — the gift box does not open until you finish the mandatory tutorial.
• Wrong game — confirm Place ID 112731528776884. Knife VS Gun DUELS codes from random videos will not work here.
• Expired code — check our codes page and expired codes archive if a string stopped working after a patch.

Rejoin the server if the UI desyncs after a long session. Never use exploits or modified clients — KNIFE DUELS enforces permanent bans for cheating.

After You Redeem

Spend your coin rewards deliberately. Browse the shop for rotating knife skins and compare value with the coin calculator. Codes accelerate early progression but do not replace mechanical skill — step on a duel pad and fight to six wins with your new loadout.

Bookmark our codes page for the latest active strings. When new codes drop, redeem immediately — limited-time rewards can expire within days.
