FAQs
What is the best Rainbet promo code?
The best code is GAMBLECS2, which offers a 100% deposit bonus up to $2,100, 60 free spins, and 20% rakeback. It unlocks the highest-value welcome package currently available and grants access to leaderboard races, reward chests, and VIP cashback tiers.
How many times can I use GAMBLECS2?
You can only use GAMBLECS2 once per newly registered account. Attempting to use it multiple times across different accounts may result in account restriction or forfeiture of bonuses under Rainbet’s anti-abuse policy.
Is there a no deposit bonus on Rainbet?
No, Rainbet does not currently offer a no deposit bonus. All bonus offers, including those tied to codes like GAMBLECS2, require a minimum deposit of $30 in cryptocurrency to be activated.
What’s the wagering requirement for bonuses?
For wager-locked bonuses, the requirement is 40x the bonus amount. For No Wager bonuses, the unlock rate is based on a formula: Wager Amount × 1% × 20%. Note that high-RTP games (97.4%+) are excluded from meeting these conditions.
Can I use Rainbet on mobile devices?
Yes. Rainbet is fully optimized for mobile use through any standard web browser. There is no need to download an app. All features, including deposits, gameplay, chat, and bonuses, are accessible from both Android and iOS devices.
Can I withdraw my bonus funds?
Yes, but only after fulfilling the full wagering requirements. For wager-locked bonuses, that means meeting the 40x condition. No Wager bonuses become withdrawable progressively as they are unlocked per the wagering formula.
Which games are eligible for free spins?
Free spins granted through GAMBLECS2 are valid on Pragmatic Play slots like Sweet Bonanza. Availability may vary depending on your country and game licensing. You can check eligible titles directly in your Rainbet account once the spins are credited.
What happens if I don’t use the spins or complete wagering?
If you don’t complete the wagering requirements within the validity period or use your spins, the bonus and all associated winnings will expire. Always check the timer on your bonus balance to avoid forfeiture.
How do I know my bonus is active?
After depositing with a promo code, check your profile’s promotional balance and bonus dashboard. If you don’t see the bonus credited immediately, do not place any wagers. Contact live chat to resolve the issue before continuing.
