Project Slayers Codes (September 2026) -- All Active & Expired Codes

By Money Lord — Founder & Editor | Updated: September 14, 2026

Here's every Project Slayers code we've tested for September 2026. We check for new codes daily and update this list the moment anything changes, so bookmark this page and come back before your next session.

Project Slayers is a Demon Slayer-inspired anime RPG on Roblox with over 678 million visits. Codes typically give you free spins for clans, breathing resets, race resets, and Wen (the in-game currency). These freebies can save you hundreds of Robux -- a single breathing reset costs 300 Robux without a code, and a race reset runs 150 Robux.

The team behind the game is Ouw Productions (the Roblox community run by Ouw2204, which also owns the Project Slayers group that publishes the experience), and they are deep into Project Slayers 2 — so code drops for the original have slowed right down. But codes can still appear during milestones or special events, so it's worth checking back regularly. For gameplay strategies and tier lists, see our Project Slayers free Robux guide.

All Active Project Slayers Codes (September 2026)

As of September 14, 2026 there are still no active Project Slayers codes. We re-checked the game's own Roblox page and two independent code trackers today — Pocket Tactics (swept September 8) and Gfinity Esports (swept September 14) — and both list the entire code archive as expired with nothing live to replace it. There is, however, a dated code coming: see the box below.

A free code is confirmed for September 18, 2026 — but you have to qualify for it first. Ouw Productions has a public Roblox event attached to Project Slayers, titled “RELEASE!!”, scheduled for 20:00 UTC on September 18, 2026 for the launch of Project Slayers 2. The event listing (created 23:22 UTC on September 7, 2026, the same hour the game was republished) states in the developer's own words that to get a free code on release you must join the Ouw Productions group and subscribe to the event on Roblox. Do both before the 18th — there is no way to qualify afterwards. We have not seen the code itself yet, and we will not guess at it; it will be added here once it is live and verified.

How to Redeem Codes in Project Slayers

  1. Open Roblox and launch Project Slayers.
  2. Once you're in the game, press M on PC or tap the menu icon on mobile to open the game menu.
  3. Click the codes button (it has a Twitter/X bird icon) on the left side of the menu.
  4. Type or paste your code into the text box. Remember, codes are case-sensitive.
  5. Press Enter or click Submit to redeem. Your rewards (spins, resets, or Wen) will appear in your inventory immediately.

Where Do New Codes Come From?

Project Slayers codes have historically been tied to specific events and milestones. The developers released codes for hitting 500K favorites (the "New500kLikesCode"), for reaching 1 million favorites, during holiday events like Christmas 2022 and New Year 2024, and as compensation for server shutdowns.

The first source to watch is Roblox itself: the Ouw Productions community page and the game's own event listing are where the September 18 release code is being gated, and both are first-party. After that, the official Discord server — still live on the same invite, though it now goes by “Slayers 2” ahead of the sequel launch — and the Project Slayers Trello board, which carries NPC locations and gameplay tips alongside any code announcements.

With the team shipping Project Slayers 2 on September 18, 2026, code drops for the original game have become rare — the next confirmed one is the release code described near the top of this page. Milestone events (like visit count achievements) can still trigger extra codes. When they do drop, codes can expire at any time without a posted deadline, so redeem them fast.

Tips for Getting the Most Out of Project Slayers

Codes are great for free spins and resets, but they're just one piece of the puzzle. Here are a few ways to maximize your progress between code drops.

Save your spins for the right moment. Clan spins from codes are valuable because Supreme clans like Kamado and Agatsuma have a 0.1% roll chance. Don't use spins until you've decided on your final build. A Kamado clan is wasted on a Slayer, and Rengoku does nothing for a Demon player.

Use private server codes. While the Private Server game pass costs 900 Robux, other players share their private server codes for free on Reddit and Discord. These let you farm bosses without competition, which speeds up leveling dramatically after level 75.

Farm Ores to skip Robux purchases. Both breathing resets (300 Robux) and race resets (150 Robux) can be bought with 3 Ores instead. Press M, click the moneybag icon, and toggle the payment method. It takes some grinding, but it saves real money.

Frequently Asked Questions

How do I redeem codes in Project Slayers?

Press M on PC or tap the menu icon on mobile. Click the codes button (Twitter/X bird icon), paste your code into the text box, and press Enter. Rewards show up in your inventory right away.

Why is my Project Slayers code not working?

Three common reasons: the code has expired (they can stop working without warning), you've already redeemed it on your account, or there's a typo. Codes are case-sensitive, so always copy and paste directly.

How often are new Project Slayers codes released?

Codes typically drop during major updates, player milestones, and holiday events. As of September 2026 the developers are focused on Project Slayers 2, which launches September 18, so new codes for the original game have become rare — the next confirmed one is the release code you qualify for by joining the Ouw Productions group and subscribing to the Roblox event.

Can I use Project Slayers codes more than once?

No. Each code can only be redeemed once per account. Attempting to reuse a code will show an error message.

Do Project Slayers codes expire?

Yes. Most codes expire, and Project Slayers codes don't come with posted expiration dates. They can stop working at any time, so redeem them as soon as you find them.

Where can I find new Project Slayers codes?

The best sources are Roblox itself — the Ouw Productions community page and the game's event listing — followed by the official Discord (now named “Slayers 2”) and the Trello board. We also check and update this page daily, so bookmarking it is the simplest option.
