Project Slayers codes give free Clan Spins, Demon Art Spins and Daily Spins, plus one-off Breathing Style and Race resets, so you can reroll a bad clan or respec without spending Wen or Robux. The game is a Demon Slayer-inspired open-world RPG by Ouw0ppai and the Ouw Productions team, released on Roblox in July 2022. It has passed 675 million visits and 1.1 million favorites and still draws several hundred concurrent players, although the studio's attention has moved to the sequel and new codes have been rare since early 2024. We test every code on this page daily and move dead ones to the expired list.

About Project Slayers
Project Slayers is an open-world action RPG on Roblox, created by Ouw0ppai in November 2020, released on July 15, 2022, and run by the Ouw Productions studio. It is built on the world of Demon Slayer: Kimetsu no Yaiba. You start as an ordinary human, roll a clan from the gacha, and take quests from villagers before choosing a side: train under a Breathing Style and hunt demons, or become a demon yourself and unlock a Blood Demon Art. Combat is a light and heavy attack system with dashes, wall climbing and combo strings, and progression runs through levels, bosses, dungeons and the drop tables behind katanas, masks and haoris.
The game shipped two large updates. Update 1, Mugen Train, arrived in November 2022 with Flame, Beast and Mist Breathing, the Dream, Swamp and Shockwave Demon Arts, the Ouwigahara dungeon and a second world, Ouwohana. Update 1.5 in May 2023 added Snow and Sound Breathing, the Ice Demon Art, a trading system and an expansion of Ouwohana. The full list of styles, arts, clans and boss drops is maintained on the community wiki.
What is happening right now
In February 2024 Ouw0ppai stopped feature work on this game and announced a full rebuild, now called Slayers 2, which the wiki lists for release on September 18, 2026, with early access for selected players in the days before. The original experience stays open and still had a maintenance update in September 2026, but the studio has not issued a new code for it since the New Year 2024 set. That is why codes matter here: the few that do appear are tied to milestones such as visit or vote counts, and they are the only free source of spins and resets in a game where clan and Breathing rerolls otherwise cost currency. You can check the live player count on the official Roblox page and follow the studio through the Project Slayers community on Roblox.
Where new codes come from
Codes on this page are checked against the Codes page of the Project Slayers Wiki, which keeps a dated expiry log, and against announcements in the official Project Slayers Discord and on the Ouw Productions YouTube channel. The Discord announcements channel is where new codes are posted first.

Project Slayers codes FAQ
Why are there no working Project Slayers codes?
The developer has not released a code for the original game since the New Year 2024 set. Ouw0ppai announced a full rebuild, Slayers 2, in February 2024 and has put the studio's effort there since. The original game is still online, so a milestone code is possible, but there is nothing to redeem at the moment.
What do Project Slayers codes usually give?
Most codes give a bundle of Clan Spins, Demon Art Spins and Daily Spins. Milestone and holiday releases often come as a set of three: one spins code, one Breathing Style reset and one race reset. A few early codes also gave small amounts of EXP or Wen.
Where do I enter codes in Project Slayers?
Once you are in the world, press M to open the menu, click the book icon, type the code into the Type Code Here box and click Submit Code. Codes do not work from the character creation screen.
My code says invalid. What went wrong?
Codes are case-sensitive and several of them use unusual punctuation, so copy them rather than typing. If the string is exact, the code has expired; every Project Slayers code released so far is now dead, and each code can only be redeemed once per account.
Will Project Slayers codes work in Slayers 2?
No. Slayers 2 is a separate Roblox experience with its own progression and its own code system, so any codes it launches with will only work there. This page tracks the original Project Slayers.
