+1 Katana Evolution Links Hub

This hub is the short list of places that matter for +1 Katana Evolution. The game is a free Roblox incremental from Gatto vs Denis (GattoHoldings), live since 11 June 2026, with about 17.4 million visits, 31 thousand favorites, an 85 percent like ratio, and 12-player servers. You do not need a fan Trello to play it. You need the experience page, the group that unlocks codes, the Discord that repeats those codes, and this wiki for ranks and routes. No public Trello was found. We will not link a fake one.

Official play URL: +1 Katana Evolution on Roblox.

Official group: Gatto vs Denis (join required for codes, 1.6M+ members).

Official Discord: discord.gg/7fKhENmTcP.

How to use those two communities without getting lost is on Discord and Group. What this fan site will and will not invent is on About the Wiki.

Play page — what it is for

The Roblox experience is the source of truth for whether the game is up, how many people are in a 12-player server, and when the platform last stamped an update. As of September 2026 that stamp sat around 4–6 September. The page is also where the A TRUE SHINOBI badge lives. It is not a patch-note blog. After you click Play, come back here only if you need a code, a rank, or a rebirth breakpoint.

Progress is individual. Sharing a server with eleven other ninjas is not a co-op campaign. If a third-party site billed this as an upcoming drop, it is late: the game has been out since June 2026.

Group — the code gate

Codes will not credit unless you are in Gatto vs Denis. That is not a wiki rule. It is the HUD rule. Join the community, wait for membership to stick, then follow how to redeem. The live strings as of September 2026 are RELEASE (10K Wins) and COOKED (50K Damage + 1 Level), listed on the codes hub. The group is also where katana idea threads appear — useful as a rumor filter, useless as a shop.

1.6 million members means the wall is noisy. Sort for developer posts before you trust a code screenshot. If a string is real, it will also land in Discord and on this wiki after we redeem it ourselves.

Discord — fast codes, still not a Trello

The invite above is the community server. Use it for new code pings and for “did the September bump break my client” questions. Do not use it as a substitute for the updates hub. Discord messages expire in your memory. The month page does not. Full etiquette and the join-group-first reminder live on the Discord page.

This wiki — unofficial on purpose

Katanaevolution.wiki is a fan resource. It is not GattoHoldings. It is not Roblox. Legal text sits at Terms, Privacy, and Cookies. Content you actually play with sits in guides, tier lists, builds, tools, and scripts. If a page here disagrees with the HUD, the HUD wins. If a page here disagrees with a random Trello clone, this wiki wins, because that Trello was not found.

Bookmark this hub if you only want outbound links. Bookmark About the Wiki if you want the verification rules. Bookmark the play URL if you just want to swing a bamboo blade and cash a win pad. Those are the only four destinations this category exists to protect.
