+1 Katana Evolution Working Codes
September 2026 list: RELEASE, COOKED, and the group join that unlocks them.
+1 Katana Evolution still has a short, high-value code list in September 2026. Both live strings are case-sensitive, both require membership in the Gatto vs Denis group, and both are strong enough to change your first hour if you spend the rewards in the right order. Use this hub as the live list, then jump to the step-by-step redeem guide when the HUD rejects a string and to code rewards explained when you need to know whether 10K Wins or 50K Damage should be spent before a rebirth.
The experience is a free-to-play Roblox incremental simulator from Gatto vs Denis (GattoHoldings), live since June 11, 2026, with an update window around September 4–6, 2026. Servers hold 12 players. Progress is individual, so a code you redeem is yours even if the rest of the server is still swinging bamboo katanas on Stage 1. Nothing here is a co-op campaign, and nothing is upcoming: the place is already live.
Live codes (September 2026)
| Code | Reward | Requirement |
|---|---|---|
| RELEASE | 10,000 Wins | Join Gatto vs Denis, type it exactly |
| COOKED | 50,000 Damage + 1 Level | Join Gatto vs Denis, type it exactly |
No expired codes are published yet. If a string from chat or a screenshot fails, treat it as a setup error first: wrong group, extra space, or lowercase letters. Do not invent extra codes from server chat.
Join the group before you type
The redeem box looks like it should work the moment you spawn, but the backend checks Gatto vs Denis membership (community 129736655). Join the group on Roblox, give it a few seconds, then hop a 12-player server if the first attempt still errors. The studio also runs Discord and posts on the group wall; a recent group post asked for katana ideas for a future update, which is a hint that more blades — and possibly more codes — will follow the September patch.
How the two rewards actually land
Wins are the currency on the GET +1 WIN pads and on the katana / click upgrade pads. One Win is enough to replace the starter bamboo katana with a wooden sword. Ten thousand Wins is not a modest gift: it is a pile you would otherwise farm by clearing staged arenas and stepping on those pads over and over. Damage is the number that opens later stages. Stage 2 lists about 300 recommended damage, Stage 3 about 5,000, Stage 5 lists 30,444, and later gates climb into the millions. COOKED’s 50,000 Damage therefore skips the early walls and leaves you staring at mid-board arenas with a bamboo or wooden blade you have not yet upgraded. The extra Level from COOKED also ticks the purple evolve bar (“Next Evolve In X Level”).
Spend Wins on katanas before you press Rebirth. Rebirth multiplies damage (about x2 at one rebirth, about x5 at three) and resets a lot of padded progress toward “noob status,” but katanas are kept. Dumping RELEASE into a rebirth you were not ready for wastes the only part of that gift that does not survive the reset. The rebirth planner and the rebirth guide cover that timing in more detail.
Redeem path, in short
Look at the top-right of the HUD for the Twitter/X icon. Open it, type into the box labeled ENTER YOUR CODE HERE, and press Redeem. Store, Rebirth, Teleport, and Inventory sit elsewhere on the same HUD and will not accept codes. If you are on mobile and cannot find the icon, rotate to landscape or look at the controls overview so you are not hunting the wrong button. Full troubleshooting for group checks, case, expired strings, and mobile versus PC lives on how to redeem codes.
What to do in the same session
New accounts should redeem, then follow the getting started guide instead of immediately hopping to Stage 5. Buy the wooden sword, check the katana tier list, and only then walk the stage damage gates. If you already have a farm loop, park on the last stage you can clear and convert RELEASE into blades rather than into a panic rebirth. Watch the updates hub and the September 2026 patch notes after each drop; this codes list will move when the next string is confirmed.
Official place: the Roblox experience +1 Katana Evolution. Ignore executors and random “free code” popups in a busy server. Codes are free, group-gated, and case-sensitive. That is the whole list until the next update.
Frequently Asked Questions
Quick answers to the most common questions.
What codes work in +1 Katana Evolution right now?
As of September 2026 the live codes are RELEASE (10,000 Wins) and COOKED (50,000 Damage plus 1 Level). Both are case-sensitive and require Gatto vs Denis group membership. No expired list has been published yet.
Why does a code say it failed even though I typed it?
You are usually not in the Gatto vs Denis group, you changed the capitalization, or you added a space. Join the group, hop a 12-player server, and type RELEASE or COOKED exactly. See the redeem guide if the X icon is missing on mobile.
Should I redeem codes before or after my first rebirth?
Redeem as soon as the group join goes through, then spend RELEASE Wins on katanas before you press Rebirth. Katanas are kept after a rebirth; unspent Wins and a lot of padded stats are not.
Where do new codes get announced?
Watch the updates hub, the September 2026 notes, the Gatto vs Denis group wall, and the Discord invite page. Do not trust random strings typed in a 12-player server unless they match this list.
Do I need Robux to use codes?
No. Codes are free. Game passes such as Starter Pack, x2 Damage, x2 Wins, +10 Speed, and OP Starter Pack are separate purchases and are not required to redeem RELEASE or COOKED.
