Kaiju Alpha is a Roblox giant-monster battleground where you pick a kaiju, smash cities, and fight other kaiju to level up and grow stronger.
To help you level up faster, the developers release free codes that give you Levels, Cells and boosts. Below, you will find all the latest working Kaiju Alpha codes, the expired codes, how to redeem them, and where to find more.
All New Kaiju Alpha Codes
- HAPPYHALLOWEEN: 31 Levels (requires 31 minutes of playtime). (==NEW==)
- NOLIMITTOTHELARVA: 20 Levels (requires 30 minutes of playtime).
- 1MILLIONMEMBERS: 50 Levels, 500,000 Cells, and a Cell & EXP Boost for 5 hours (requires joining the SULU OPPA group and 60 minutes of playtime).
Tip: Redeem these codes as soon as possible, because Kaiju Alpha codes can expire quickly and without warning — HAPPYHALLOWEEN is expected to expire very soon. Note that each code also needs a certain amount of playtime before it will redeem. Bookmark this page and check back regularly so you never miss a new code.

Why Are My Kaiju Alpha Codes Not Working?
If a Kaiju Alpha code is not working for you, it is usually because of one of these reasons:
Double-Check for Typos: The most common reason a code fails is a typing mistake. Codes must be entered exactly as shown — even one wrong letter or an extra space will stop the code from working. Copy and paste the code directly from our list instead of typing it yourself.
You Have Not Played Long Enough: Kaiju Alpha codes have playtime requirements — 30, 31 or 60 minutes depending on the code — and 1MILLIONMEMBERS also needs you to join the SULU OPPA group. Play a bit longer, join the group, and try again. Restarting the game can also fix a brand-new code that will not redeem.
The Code Has Expired: Developers deactivate old codes from time to time, often without any notice. If a code still does not work after checking your spelling and your playtime, it has most likely expired. Check our active list above — we only list codes that are confirmed working.
