Questions about this offer
Do I need a promo code for the Rainbowspins offer?
Yes. Rainbowspins publishes the code PRO, to be entered deposit. Without it the offer does not apply.
How much do I have to pay in?
The page states a minimum deposit of £20. Paying in less does not trigger the offer, and paying in more does not increase it unless the terms say so.
Can I withdraw the winnings straight away?
Not immediately. The reward carries a 10× wagering requirement, which means staking it 10 times over before the balance becomes withdrawable.
When does it end?
The page gives no end date. It runs until the operator withdraws it, and this site records the day that happens.
Which games does it work on?
The terms name Starburst, Irish Pot Luck, Fluffy Favourites, Chilli Heat. Play outside that list and the stake may not count — this is the condition people most often miss.
Is this offer available to existing customers?
The terms do not restrict it to new accounts, so existing customers should be eligible — but opt-in rules still apply.
