Kaiju Alpha Codes [Rose Biollante] (September 2026) – Free Levels, EXP & Cells
Earnaldo players have recorded 450+ real Robux payouts on video — watch the proof and earn Robux yourself.
· September 9 — added KAONTOP and xecretisreal (all three trackers list them); expired DeawyGIGACHAD and Srryforbug; two Srry… codes now disputed
· September 4 — found the game live again at place ID 127403135954624 under the verified group SULU OPPA; documented the Options-menu Code box and published four codes
· August 29 — liveness test re-run on the old place ID: still a 302 to Title-Unavailable
Yes — Kaiju Alpha has working codes again, and they pay out levels, EXP and Cells. The game we previously reported as removed did not come back at its old address: it relaunched at place ID 127403135954624 on August 17, 2026, and the new build added the code box the old one never had. Update 48 brought two fresh ones — KAONTOP and xecretisreal — while two of the relaunch codes have stopped working. Here is which ones we can actually stand behind.
302 to /Title-Unavailable while a known-live game answered 301 to its own slug in the same minute. The old developer group, SULU KAKA, still exists but is locked and now lists zero public games.
All Kaiju Alpha Codes (September 2026)
Active codes
Codes are case-sensitive — the capitalisation below is the exact string, taken from Roblox Den's copy-to-clipboard values rather than its rendered text, which normalises case.
| Code | Reward | Status |
|---|---|---|
| KAONTOP | 60M EXP and 60M Cells — NEW | Active |
| xecretisreal | 60M EXP and 60M Cells — NEW | Active |
| Srryforrevertlevel | 50 levels — only works on a level 100+ Kaiju | Active — disputed |
| Srryforbugs | An EXP boost — sources disagree on the size (see below) | Active — disputed |
The two new codes are the best-evidenced on this page. KAONTOP and xecretisreal are listed as active by all three of the publishers we track under three different owners — Roblox Den, Pocket Tactics (Network N) and Game Rant (Valnet) — and Roblox Den and Game Rant agree on the same 60,000,000 EXP and 60,000,000 Cells payout. Pocket Tactics instead describes the reward as an hour of EXP boost and an hour of Cell boost; we print the two-source itemised figure and flag that disagreement rather than pick a favourite.
We write xecretisreal in lower case because that is how both Roblox Den's copy-to-clipboard value and Game Rant's table render it; only Pocket Tactics upper-cases it. Codes here are case-sensitive, so use the lower-case form first.
Two codes moved to the expired list. DeawyGIGACHAD, the code we were most confident in on September 4, is now listed as expired by both Pocket Tactics and Game Rant against Roblox Den still showing it active — two owners to one, so we retire it. Srryforbug is expired on both Pocket Tactics and Roblox Den, which settles it. The remaining two Srry… codes split one-for-one (Pocket Tactics expired, Roblox Den active), so they stay in the table marked disputed until a second source breaks the tie — one source each way is not enough to retire a working code.
Expired codes
The first two retirements landed this week, both relaunch-era apology codes. We archive dead codes here rather than deleting them — if a code you find elsewhere is on this list, it is not worth typing.
| Code | Reward | Status |
|---|---|---|
| DeawyGIGACHAD | 30 levels, no requirements | Expired |
| Srryforbug | 30M EXP and 30M Cells | Expired |

The code box is not on the main screen — it is the last item inside the settings panel, which is why the old build's menus looked codeless. Exact steps:
- Open Kaiju Alpha and wait until your kaiju has spawned and can move.
- Press the OPTION button on the left-hand side of the screen.
- Scroll to the bottom of the Options panel. Below the Time Of Day and Kill Indicator rows there is a field headed Code with the placeholder text Enter here.
- Type or paste one code, exactly as capitalised above, and press Enter.
- Check your level or Cells to confirm it landed, then redeem the next one.
That panel is described from real video frames of an August 29, 2026 walkthrough — the empty Enter here field in one, DeawyGIGACHAD typed into it in another — not from a tracker's prose. It is also what settles the older question on this page: the redemption system genuinely exists now.
How We Verified This List
Re-checked on September 9, 2026 against the Roblox games API (universe 10732236937) for the live title, description and stats, and the groups API for the developer group. For the codes we compared three publishers under three separate owners: Roblox Den (exact case from its data-copy attributes, stamped 01:57 PM 09/09/2026), Pocket Tactics (Network N, September 6) and Game Rant (Valnet, September 5). We deliberately dropped the GAMURS pages from the count this run — Pro Game Guides and Destructoid carry identical wording and identical row order, so they are one voice, not two. Every source links place ID 127403135954624, so these codes belong to the game running today, not the dead one. The September 4 liveness test on the old place ID was not re-run today; that finding is dated where it appears.
Two things we deliberately did not use. A single-game site, kaijualphas.wiki, ranks for this query; its WHOIS shows it was registered on August 31, 2026 — two weeks after the relaunch — through Spaceship, Inc. behind Cloudflare with the registrant withheld, which is the auto-generated-site fingerprint, so it is not a source here. And we make no claim about this game's badges or game passes: both Roblox endpoints currently return an empty list for a known-live control game, so an empty result proves nothing today. Our standards are in how we verify Roblox codes.
How to Get More Kaiju Alpha Codes
The codes on this page are apology and catch-up codes tied to the relaunch, which tells you where the next ones come from: the developer's own channels around a patch. Watch the SULU OPPA group (458,386 members as of September 9, 2026) — the game description asks players to join it for "news and exclusive events", and the group feed is the first place a code would appear. The description itself is the other primary source: it leads with the current update number and its headline addition, and it is where the old build published everything it ever announced.
The title is a signal too: it carries a bracket tag naming the newest kaiju, and it moved again this week — [ Rose Biollante ] as of September 9, 2026, up from [ Godzilla Terrestris ] on September 4. A tag change means a patch shipped, and both new codes on this page arrived alongside one. Note the tag names a kaiju, not a version number: the update number lives in the description, which now opens with UPDATE 48 — Added Rose Biollante.
Why Aren't My Codes Working?
Four common causes, in the order they actually bite:
- Capitalisation. These are case-sensitive and awkwardly cased on purpose — DeawyGIGACHAD, not DEAWYGIGACHAD. Typing them by hand on mobile is where most failures come from; your keyboard's autocorrect will happily change them.
- The level gate. Srryforrevertlevel only applies to a Kaiju at level 100 or above. On a fresh account it will simply fail, and that is not the code being dead.
- One redemption per account. A code you already used returns an error the second time, which reads identically to an expired code.
- An old server. If a code was issued after your server started, rejoin the game before deciding it is broken.
When Are New Codes Released?
Honestly: we do not have a long enough history to promise a cadence. The relaunched game is weeks old, and the four codes we can see all cluster around the move and the bugs that came with it. The old build, over roughly three months of near-weekly updates, issued none at all — the code box did not exist. So the useful read is that codes here are event-driven, not scheduled: expect them after a disruptive patch or a milestone, and treat any list promising a steady stream as guesswork.
Kaiju Alpha in Numbers
All read live from the Roblox API on September 9, 2026. The relaunched experience has 11,737,507 visits and 33,747 favourites, with 19,174 likes against 1,547 dislikes — about 92.5% positive. Concurrency sat between 6,291 and 6,370 players across four reads from 20:15 to 20:16 UTC; that is one evening window on one day, not a median and not a peak, so read it as a single point. For scale, the same page recorded roughly 4,030–4,062 concurrent and 8,379,208 visits on September 4 — the game added about 3.36 million visits in five days. Servers hold 25 players. The place was created on August 17, 2026 and the description now leads with Update 48, which added Rose Biollante.
The build this page used to cover measured roughly 9,100 concurrent players and 67.1 million visits on July 31, 2026 before it went dark. The relaunch started from zero, so 8.4 million visits in 18 days is fast — but it is a separate count, not a continuation of the old one.

Frequently Asked Questions
Yes. As of September 9, 2026 four codes are circulating for the game at place ID 127403135954624: KAONTOP and xecretisreal, both for 60M EXP and 60M Cells and both added with Update 48, plus Srryforrevertlevel for 50 levels on a level 100+ Kaiju and Srryforbugs for an EXP boost. The two new codes are the best-evidenced — three publishers under three different owners list them as active. DeawyGIGACHAD and Srryforbug have expired.
Press the OPTION button on the left side of the screen and scroll to the bottom of the panel. Below the Time Of Day and Kill Indicator rows there is a field headed "Code" with the placeholder "Enter here". Type the code exactly as capitalised and press Enter. The old build of Kaiju Alpha had no such field, which is why this page previously said the game had no code system.
The original place ID, 139769003880269, became unavailable around August 19, 2026 and still returned a redirect to Title-Unavailable when we last tested it on September 4, 2026; the old developer group, SULU KAKA, is locked and lists no public games. A game with the same name, description template and continued update numbering has been running since August 17, 2026 at place ID 127403135954624 under the verified group SULU OPPA. Roblox does not publish a reason for the original removal and we will not guess at one.
Final Thoughts
This page was wrong in a way worth stating plainly: for two weeks it told readers Kaiju Alpha was gone and had never had codes, while a Kaiju Alpha with a working Code box ran at a different address the whole time. Our liveness check watched the old place ID and never asked whether the game had moved. The list above is the correction, with its weakest link — one disputed reward figure — labelled rather than smoothed over. If a code dies it moves to the expired table here rather than disappearing.
