What Promo Codes Are
Promo codes at Rainbow Spins are short letter-and-number codes that unlock a specific bonus. A code can add a deposit match, free spins on a named slot, or a cashback deal, and each code comes with its own limits such as a minimum deposit, an expiry date, and game restrictions.
Where To Find Them
Rainbow Spins publishes promo codes in three places: marketing emails, SMS (if you opted in), and the Promotions page inside your account. You’ll also see time-limited codes in push notifications from the mobile site/app if notifications are enabled.
How To Activate A Promo Code
Log in, open Cashier, choose your payment method, and enter the code in the Promo code field before you confirm the deposit. If the code is for free spins without a deposit, go to My account → Bonuses → Redeem code, paste the code, and submit; the bonus then appears in your bonus wallet with its wagering requirement and expiry timer.
Example Promo Codes (Fictional)
- RAINBOW50 — 50% deposit bonus up to $100; minimum deposit $20; 35x wagering on bonus; valid for 7 days after activation.
- SPINS20GEMS — 20 free spins on “Gem Rush”; spins expire in 72 hours; winnings capped at $50; 30x wagering on winnings.
- WEEKEND10BACK — 10% cashback on net losses up to $25, credited on Monday; cashback has 10x wagering; valid Friday–Sunday.
In practice, you either enter the code during checkout in the cashier or redeem it in the bonuses section, then you play within the listed time limit and wagering rules shown in your bonus wallet.
