Rain.gg Referral Code FAQ

The Rain.gg referral code is WELC. Enter it in the referral field when you register and you get 3 free cases straight away plus a 5% bonus on every deposit. RAIN9 is a working alternative that pays exactly the same. Both were checked on September 17, 2026.

The referral code field appears on the Rain.gg registration form, directly under your account details — it is sometimes collapsed behind a "Have a referral code?" link. If you have already registered, open Settings and look for the Referral or Promo section, where the same field appears.

On Rain.gg they are the same thing. "Referral code", "promo code" and "coupon code" all describe the affiliate code you enter at signup for 3 free cases and a 5% deposit bonus. Rain.gg uses one field for it, so you do not need to hunt for a separate promo box.

You get 3 free cases. They are credited to your inventory as soon as a valid referral code is applied, before you deposit anything. The cases are entry-level, so treat them as a way to try the platform rather than as a meaningful payout.

Almost always this means a code is already attached to the account. Rain.gg allows one referral code per account, applied at registration and never changed afterwards. If WELC will not apply, try RAIN9 on a genuinely new account; if neither takes, your account already has a referrer.

No. The referral code is locked to your account at registration and cannot be swapped later, which is why it is worth entering one before you finish signing up. If you skipped the field entirely, contact Rain.gg support — they will not always add one retroactively.

Affiliate referral codes like WELC and RAIN9 do not carry an expiry date — they stay active as long as the affiliate account behind them does. That is different from limited-time site promotions. We re-test both codes and last confirmed them working on September 17, 2026.

Neither pays more — both give 3 free cases and a 5% deposit bonus. We list WELC first because it is the one we test first and it applies cleanly on new accounts. Use RAIN9 if WELC does not take. Any site claiming one pays a bigger bonus is guessing.

No, the 5% applies to deposits on an ongoing basis rather than only your first one. It is calculated on the deposit amount and credited with the deposit itself. Confirm current terms on Rain.gg before depositing, since the platform can change bonus rules without notice.

No. The 3 free cases are credited when the code is applied at signup, with no deposit required. The 5% bonus only becomes relevant once you do deposit, so you can enter a code, open your free cases and stop there if you want to.

Yes. WELC and RAIN9 were both re-tested on a live Rain.gg account and confirmed working on September 17, 2026. We re-check them weekly rather than simply changing the date at the top of the page, and we remove codes that stop applying instead of leaving them listed.

Rain.gg is a CS2 case-opening and case-battle site where you open virtual cases for Counter-Strike 2 skins. It runs a provably fair system that lets you verify outcomes cryptographically, and supports skin and cryptocurrency deposits and withdrawals. It is a gambling site and is restricted to users aged 18 and over.

Rain.gg is an established CS2 case site with a provably fair system you can verify yourself using the server and client seeds for each roll. That verifies fairness of outcomes, not that gambling is low-risk. Only stake money you can afford to lose, and do not treat free cases as income.

No — one referral code per account, applied at registration. Codes with names implying they stack do not change this; the name is marketing, not a feature. Creating extra accounts to claim the bonus repeatedly breaks Rain.gg’s terms and risks losing your balance.

Rain.gg supports CS2 skin withdrawals and cryptocurrency payouts including Bitcoin, Ethereum and Litecoin. Open the withdrawal section, pick a method and follow the prompts; crypto withdrawals usually clear within minutes. Check any wagering requirement attached to bonus funds before you try to cash out.

Yes, Rain.gg runs in a mobile browser with no app to install — case opening, battles, deposits and withdrawals all work on a phone. The referral code field appears on the mobile registration form in the same place, so you can enter WELC or RAIN9 on mobile without switching to desktop.

Yes, and it is worth being upfront about it. raingg.net is an independent affiliate site: if you sign up through our links we may earn a commission from Rain.gg at no extra cost to you. That does not change your bonus, which is the same 5% and 3 cases either way.

Each roll combines a server seed that Rain.gg commits to in advance as a hash with a client seed you control. After the roll the server seed is revealed, so you can re-hash it and confirm the outcome was fixed before you played and was not altered mid-round.
