Rain.gg Referral Code RAIN9
Checked by The raingg.net Editorial Team· Last verified
RAIN9 is a working Rain.gg referral code paying 3 free cases at signup and a 5% deposit bonus — identical to WELC. Use it if WELC will not apply to your account, or simply because you prefer it.
When to use RAIN9 instead of WELC
RAIN9 is the second Rain.gg referral code we track and the one to reach for when WELC does not take. It pays exactly the same rewards — 3 free cases on signup and a 5% bonus on deposits — through a different affiliate link, so it is a genuine fallback rather than a better offer. Some players also simply prefer it because it is easier to remember on mobile.
WELC was rejected on your account
RAIN9 runs through a separate affiliate link, so it is a genuine second attempt rather than the same code under a different name.
You are typing it on a phone
Five characters with one digit is harder to fumble than a word code, and there is no autocorrect risk.
You found RAIN9 first
No reason to switch. The reward is the same, so the code you already have in front of you is the right one.
What RAIN9 does not do
RAIN9 is widely advertised as an "exclusive" or "premium" code. It is not. Being straight about this matters more than the marketing, because acting on those claims costs you money.
Gives a bigger deposit bonus
It is 5%, the same as every other working code.
Unlocks higher-tier free cases
The 3 cases are the standard entry-level set.
Improves your drop odds
Referral codes do not touch drop rates. Outcomes are set by the provably fair seed pair.
Stacks with a second code
One referral code per account, permanently. Nothing stacks.
Includes rakeback
Rakeback, if offered, comes from Rain.gg account tiers — not from which referral code you entered.
So why use any code at all?
Because the 3 free cases and the 5% are real, and you only get them if a code is attached before you finish registering. Signing up with an empty referral field simply forfeits them.
Getting the code right
The code is RAIN9 — five characters, one digit, no space. These are the variants that get typed by mistake.
| Typed as | What happens |
|---|---|
| RAIN 9 | A space breaks it. The code has no space. |
| RAIN09 | One digit, not two. There is no leading zero. |
| RAINGG9 | Confuses the site name with the code. It is RAIN9. |
| RA1N9 | The letter i, not the numeral one. |
| rain9 | Actually fine — codes are not case sensitive. |
Pasting is safer than typing, but check for a trailing space — it is the single most common reason a valid code appears to fail.
Where to enter RAIN9
- 1
Open the Rain.gg registration form
Steam or email both work. The referral field is on this form, not on a separate page.
- 2
Expand "Have a referral code?"
The input is usually collapsed. On mobile, scroll within the form rather than the page.
- 3
Enter RAIN9
Case does not matter. A trailing space does.
- 4
Finish signing up
3 cases appear in your inventory; the 5% applies to deposits from then on.
RAIN9 vs WELC
Use RAIN9 if WELC did not apply to your account, or if you just prefer it. The rewards are identical — 5% deposit bonus and 3 free cases — so there is no wrong choice between the two.
| Code | Free cases | Deposit bonus | Use when |
|---|---|---|---|
| RAIN9 | 3 | 5% | WELC was rejected, or preference |
| WELC | 3 | 5% | Signing up for the first time |

- 1. We register a clean Rain.gg account and enter the code in the referral field, rather than copying a list from another site.
- 2. We confirm the 3 free cases actually land in the inventory and that the 5% shows against a test deposit.
- 3. Codes are re-tested weekly. Anything that stops applying is removed from the list, not left up with a refreshed date.

RAIN9 code questions
What is the RAIN9 code on Rain.gg?

Does RAIN9 give a bigger bonus than other codes?
No. RAIN9 pays 3 free cases and a 5% deposit bonus, the same as every other working Rain.gg referral code. Sites advertising RAIN9 as a larger or exclusive offer are describing the standard affiliate reward.
Should I use RAIN9 or WELC?
Either. The rewards are identical, so there is no wrong choice. We list WELC first because it is the code we test first; RAIN9 is the one to try if WELC will not apply to your account.
Can I use RAIN9 if I already used another code?
No. Rain.gg allows one referral code per account, applied at registration and locked afterwards. If a code is already attached, RAIN9 will be rejected — that is the account state, not a problem with the code.
