1. Signup / partner code
A short code such as WELC or Fin attached to a rollbit.com/referral/… link. New players use it during registration to unlock the current welcome / rakeback offer. That is the code this site verifies.
Rollbit Referral Code 2026: Use WELC
Searching for a Rollbit referral code? The signup code to use on rollbitreferralcode.com is WELC. This page also covers the refer-a-friend program — 10% of the house edge and up to 10 personal codes — so both meanings of the search are answered in one place.

Quick answer: Use WELC at signup via rollbit.com/referral/welc. Alternative: Fin. If you already have an account and want to earn from friends, create personal codes in Account → Referrals — that is a different flow from the signup code.

What is a Rollbit referral code?
People type “Rollbit referral code” for two different jobs. Mixing them up is why a lot of guides feel incomplete.
2. Personal refer-a-friend code
After you have an account, Rollbit lets you create up to 10 custom codes. Friends attach one of yours. You earn 10% of the house edge on their bets for as long as they play. See the referral program breakdown.
How to use WELC at signup
Partner codes are meant for new accounts. The referral link is safer than typing from memory because it pre-fills the field.
- Open the referral link. Go to https://rollbit.com/referral/welc so code WELC is attached to the session.
- Create the account. Click Register / Sign Up. Enter email and password, or use an allowed login method, and accept the Terms.
- Confirm the code. Check that WELC is in the referral field. If it is empty, type it manually.
- Deposit to activate rewards. Make a crypto deposit. Welcome / rakeback offers follow Rollbit’s live cashier rules for your region.

How the Rollbit referral program works
This is the in-account system: you invite players with codes you create, then earn a slice of house edge on their bets. It is not a one-off coupon.
- Reward: 10% of the house edge on eligible referred wagers.
- Limit: up to 10 personal codes per account.
- Codes are custom. Once created, they usually cannot be deleted.
- You cannot attach a code you generated yourself.
- Tracking lives on the Referrals page (wagered, commission, claim).
New players you invite still get access to Rollbit’s normal promotions — welcome rakeback-style offers, races, VIP. They do not need a separate “no deposit” coupon for your 10% to start counting after they play. Details: Rollbit referral rewards.
How to create and share your own code
- Log in at Rollbit and open Account → Referrals (sometimes listed under Cashier).
- Type a custom code and create it. Choose carefully — the cap is 10 and codes are not typically removable.
- Share the code or the matching referral link. Public spam on forums can get a code or account restricted.
- When someone attaches the code and wagers, commission accrues on the Referrals dashboard. Claim when the button is active.
How a friend applies your code
Partner links like WELC are designed for registration. Personal friend codes are often added after signup: create the account, then open Referrals and paste the code. If Rollbit shows a referral field during sign-up, they can enter it there instead. Confirm in the live UI before they deposit.
Commission example (10% of house edge)
Suppose a referred player wagers $100 on a slot with a 3.47% house edge (about 96.53% RTP). Theoretical house edge on that spin cycle is $3.47. Your 10% cut is about $0.35 — not $10. Ten friends doing the same is still only a few dollars unless they keep playing. The value is lifetime volume, not a single bet.
| Wager | House edge | Theoretical edge | Your 10% |
|---|---|---|---|
| $100 | 3.47% | $3.47 | ~$0.35 |
| $1,000 | 3.47% | $34.70 | ~$3.47 |
| $100 (Crash ~1%) | ~1% | ~$1.00 | ~$0.10 |
This is illustrative math, not a payout guarantee. Eligibility, game weighting and claim rules follow Rollbit’s current referral terms.
Referral code vs promo code vs coupon
| Name people use | What it usually is on Rollbit |
|---|---|
| Referral / affiliate / signup code | Partner tracking at registration (WELC / Fin) or a personal code you created. |
| Promo / bonus code | Same signup field in most cases. See Rollbit promo codes. |
| Coupon / social drop | Short-lived bonus drops. Not the same as a personal refer-a-friend code. |
