I track every publicly documented code for Kaiju Alpha by SULU KAKA and rate each one by confidence level. No invented reward values — if I haven't confirmed a code, I say so.
SULU KAKA does not publish code expiry windows, and Kaiju Alpha codes routinely expire within days of release — especially big launch codes. As of this re-check there is no code independently confirmed active. The most recently documented code (LIKE1500, dated 2026-05-10) is now several weeks old and is most likely expired, so it sits in the Code history table below rather than being presented as a working active code. We re-check on each update and promote a code here the moment a working one is confirmed.
We will not present a stale code as active. When SULU KAKA releases a new code and it is confirmed working, it will appear here with a fresh verification date. In the meantime you can still try the most recent entry in the Code history table on a fresh server — but expect older codes to return an invalid/expired error.
I tested the redemption flow in-game as of launch week. The menu location can shift with UI updates, so treat step 3 as approximate.
Every code I've tracked, with its last known status and the update it was associated with. Expired codes are kept as reference — they will not work if re-entered.
| Code | Reported reward | Update | Status |
|---|---|---|---|
| LIKE1500 | 3,000 Gems + 1,000 Coins (reported) | Update 24 | Expired |
| ALPHA2024 | Unknown — unconfirmed | Early launch | Expired |
| SULUKAKA | Unknown — community mention | Unknown | Expired |
| UPDATE20 | Gems (amount unconfirmed) | Update 20 era | Expired |
| KAIJU100K | Community milestone reward | Milestone event | Expired |
| SORRYFORLAG | Compensation (unconfirmed) | Various | Expired |
Reward amounts marked "unconfirmed" were not personally tested and may be inaccurate.
SULU KAKA typically drops codes around major update milestones, like-count events, and community events.
Every code on this page carries a confidence rating so you know exactly how much to trust the reward values.
As of the May 31, 2026 re-check, no code is independently confirmed active. The most recent documented code, LIKE1500 (May 10, 2026, reported 3,000 Gems + 1,000 Coins), is now likely expired and has been moved to the code history below. Check back around each update for a freshly verified code.
Join the active Kaiju Alpha experience, open the codes or rewards menu, type the code exactly, and confirm. Codes are case-sensitive.
The most likely cause is that the code has expired. Try a fresh server first. If it still fails, the code is no longer active.
Yes — based on standard Roblox code behaviour and community reports, each code can be redeemed once per Roblox account.
There is no fixed schedule. Codes typically appear around major updates, like milestones, and special events. I update this page whenever a new code is documented.
Kaiju Alpha codes from SULU KAKA are not region-locked at the code level — the same code works for any account that can connect to the Roblox experience. The friction tends to be timing: codes can expire fast, especially the bigger-reward launch codes that get hit in 24-48 hours. If a code returns 'invalid' for you but worked for someone else in a different country, it's almost certainly expired rather than blocked. Cross-check with the most recent SULU KAKA group post timestamp before assuming a regional issue.
I source codes from the SULU KAKA Roblox group, community tracking pages, and direct in-game testing where possible. Reward values that I have not personally confirmed are marked medium or low confidence. I do not fabricate values — if something is uncertain, it is labelled as such. Last reviewed May 11, 2026.
