What is 20% Rakeback on Rainbet Casino?
Rakeback is a loyalty rebate that returns a percentage of the casino’s house edge from your eligible wagers directly to your account, with no required playthrough to withdraw funds. The BACK20 code boosts your default rakeback rate to 20% for the duration of your account activity (terms may be adjusted by Rainbet with 7 days’ prior notice to users).
Eligible wagers include all standard slots, table games, and live dealer games offered on Rainbet, excluding prohibited hedge bets and bonus-funded wagers (if applicable).
Rakeback is calculated based on your net eligible wagers for the prior week, and credited as fully withdrawable cash or bonus funds per Rainbet’s current terms.
