Kaiju Alpha is a kaiju fighting game. You pick a monster, learn five skills and two roars mapped to the number keys, and fight other players and bosses across a set of islands the developers keep adding to.
Tokens are the currency behind the unlocks, and codes are one of the ways to earn them. This page lists every Kaiju Alpha code that currently works, alongside the ones retired as the update list has grown.
All Working Kaiju Alpha Codes
- NOLIMITTOTHELARVA: 20 Levels (play for 30 minutes first)
- 1MILLIONMEMBERS: 50 Levels, a Cell and EXP Boost for 5 hours, and 500,000 Cells (join the SULU OPPA group and play for 60 minutes first)
- SrryForBugGuys: 100 Tokens
Codes tied to the group pay out only after the account has joined the SULU OPPA group on Roblox and logged some time in the game. The usual pattern is an apology code for a rough patch, live for a few days, then retired, so many of the dead codes are variations on the word sorry.

How to Redeem Kaiju Alpha Codes
- Open Kaiju Alpha on Roblox and wait for the map to load.
- Click the OPTION icon in the game interface.
- Scroll down the menu to the code field near the bottom.
- Paste the code into the Enter here box.
- Press the Enter key to claim the reward.
The box is at the bottom of the Options menu rather than on a screen of its own, which is the step people miss. Kaiju Alpha codes also mix cases in awkward places, so paste rather than retype.
What Tokens Actually Buy
Tokens are the single currency here, spent on the kaiju roster and the skins attached to it, so a code reward converts directly into something you can play as rather than into a boost you have to spend well.
The amount a single code pays is a modest sum against the roster, which runs to dozens of monsters including the Godzilla and Evangelion inspired units the game keeps adding, but it is free progress towards the next unlock rather than a token gesture.
The expired codes tell you what else the game has paid in the past: experience and cell boosts on timers, and in one case a hundred thousand Cells. Those boost codes are the ones worth waiting for, since they multiply a session rather than adding to a total.
What Is Kaiju Alpha?
Kaiju Alpha is a kaiju fighting game: you pick a monster, learn five skills and two roars mapped to the number keys, and fight other players and bosses across islands that the developers keep adding to.
It is made by SULU OPPA and opened on 17 August 2026, which makes it the youngest game on this list by more than a year. As of 7 October 2026 it had 33.9 million visits and 68.3 thousand favorites, with about 9.6 thousand people playing at once, and it is on its fifty second update with a Halloween theme live.
Where to Find New Kaiju Alpha Codes
There is no schedule to watch here. A code appears when an update goes wrong, so the useful signal is the update itself: a patch that reverts progress or breaks a skill is usually followed by a code within a day.
They are posted in the Kaiju Alpha Discord server, the developer community linked from the game page, and the Roblox description carries the update notes rather than the codes themselves.
For more of the same, see our Creatures of Sonaria codes and Blade Ball codes.
Frequently Asked Questions
How many Kaiju Alpha codes are working right now?
Check the working list at the top of this page. There is no schedule here: a code appears when an update goes wrong, so a patch that reverts progress is the signal to come back.
Where do I enter codes in Kaiju Alpha?
In the Options menu. Open it from the game interface and scroll to the bottom, where a box labelled Enter here takes the code and the Enter key submits it.
What do Kaiju Alpha codes give you?
Tokens, which buy monsters and skins, are the usual reward. Codes have also paid Levels, Cells and timed experience boosts, so the reward type depends on what the code was issued for.
Why did my Kaiju Alpha code not work?
Capitalisation, almost always, because several codes differ only in case. If it still fails the code has been retired.
