Rainbet launched its US sweepstakes site, Rainbet.us, on October 13, 2026. It’s a separate platform from the Rainbet brand you might know from other markets, with its own operator, its own coins and its own rules for US players. This page covers only the US sweepstakes offer. Everything below has been checked against Rainbet.us’s published Sweepstakes Rules, Terms of Service and Responsible Gaming policy.
What the Rainbet.us Promo Code Gets You
The Rainbet.us welcome package has two parts. You can claim the first part without spending anything. The second is optional and only applies if you decide to buy a Gold Coin package.
| Offer | What You Get | Purchase Needed? |
|---|---|---|
| No-purchase bonus | 10,000 GC + 1 free RC | No |
| First-purchase bonus | 500,000 GC + 25 RC | Yes, $15 minimum |
| Total welcome value | Up to 510,000 GC + 26 RC | Optional |
No-Purchase Bonus: 10,000 GC + 1 Free RC
Sign up with code TWRBUS and you can claim 10,000 Gold Coins plus 1 Rainbet Cash without buying anything. Gold Coins let you try the full game lobby for fun. The 1 RC is a sweepstakes coin: play it through once in a Rainbet Cash game and any RC you win can count toward a prize redemption.
This also works as Rainbet.us’s daily reward. Once your account is active, you can claim free Rainbet Cash once every 24 hours. Rainbet.us’s Sweepstakes Rules note that the daily amount “may vary” at the operator’s discretion, so check the bonus tab when you log in.
First-Purchase Bonus: 500,000 GC + 25 RC
If you decide to buy coins, a first purchase of $15 or more with code TWRBUS unlocks 500,000 Gold Coins and 25 Rainbet Cash. You never need to buy coins to play or to redeem prizes, and buying coins does not improve your chances of winning.
Important: At the time of checking, other publishers reported that the 25 RC portion of the first-purchase bonus is credited after you contact Rainbet.us customer support. If your 25 RC doesn’t appear after your first purchase, open live chat, mention code TWRBUS and ask for the bonus to be added.
Rainbet.us
Pros
- Generous 500,000 GC welcome package

How to Claim the Rainbet.us Promo Code TWRBUS
Claiming the offer takes a few minutes:
- Open Rainbet.us through our link. Select the claim button on this page so the TWRBUS offer attaches to your new account.
- Register your account. Sign up with email and a password, or with one of the social and wallet logins: Google, Steam, Discord, Telegram, X, Solana, MetaMask or Line. Confirm that you are 18+ (or the age of majority in your state) and live in an eligible US state.
- Enter promo code TWRBUS. Add the code at sign-up, or at checkout if you go on to make a purchase.
- Claim your free coins. Open the rewards area and collect your 10,000 GC + 1 RC. No purchase is needed.
- Optional: make a first purchase of $15+. Choose a Gold Coin package worth $15 or more to unlock 500,000 GC + 25 RC.
- Verify your identity. You don’t need KYC to start playing, but Level 2 verification unlocks the free daily Gold Coins, and full KYC is required before any prize redemption.
You need to enable location services to use Rainbet.us. The site checks that you’re physically inside an eligible US state.

Rainbet.us Promo Code Terms and Conditions
These are the terms that matter most. They come from Rainbet.us’s Sweepstakes Rules and Terms of Service (Terms updated July 29, 2026).
| Term | What It Means |
|---|---|
| Age | 18+ or the local age of majority, whichever is higher |
| Residency | Legal US residents in eligible states only |
| Accounts | One account per person; registrations may be limited per IP address |
| Minimum purchase | $15 for the 500,000 GC + 25 RC first-purchase offer |
| RC playthrough | RC must be played at least once; Rainbet.us may require up to three plays |
| Gold Coins | No cash value; cannot be redeemed for prizes |
| Purchases | Final and non-refundable; shown on statements as “Sweepstone” |
| Inactivity | Accounts with no gameplay for 60 days become dormant and coins expire |
| Promotions | Can be changed or withdrawn without notice |
How Gold Coins and Rainbet Cash Work
Rainbet.us uses the standard two-coin sweepstakes model, under its own names. If you’ve used sweepstakes casinos like Crown Coins Casino or Stake.us, Rainbet Cash does the same job as Sweeps Coins.
| Feature | Gold Coins (GC) | Rainbet Cash (RC) |
|---|---|---|
| Purpose | Play for fun | Sweepstakes entries |
| Can you buy it? | Yes, in coin packages | No, bonus only |
| Redeemable for prizes? | No | Yes, after playthrough |
| How you get it | Sign-up, daily rewards, purchases | Daily reward, bonus with packs, promos |
Use Gold Coins to try new games without pressure. Use Rainbet Cash in eligible sweepstakes games, and play it through at least once before you count it toward a redemption.
Rainbet.us Daily Rewards and Promotions for Existing Players
After the welcome offer, Rainbet.us keeps adding rewards based on how often and how much you play. These were the published promotions when we checked:
| Promotion | How Often | How It Works |
|---|---|---|
| Daily reward | Every 24 hours | Free GC + RC, no purchase needed |
| Daily Gold Coins | Every 24 hours | 1,000 free GC after Level 2 verification |
| Top-up | When balance runs low | Free 1,000 GC refill when wallet and vault drop below 10 |
| Rakeback | Every 15 minutes | Returns a share of your gameplay volume |
| Races | Daily, weekly, monthly | Leaderboard races for extra coins |
| Weekly bonus | Once a week | Up to 1M GC, scales with your weekly play |
| Mid-month bonus | 16th of each month | Based on play in the prior period |
| Monthly bonus | End of each month | Scales with monthly play |
| Rank-up rewards | Each new rank | Five ranks, from Bronze to Diamond |
| Weekly free spins | Once a week | Gold rank and above |
Rainbet.us also runs a VIP program. Players with over 2.5 million in total gameplay volume get a personal VIP host and 10% lossback. Free Rainbet Cash giveaways also run on Rainbet.us’s official X (@Rainbetusa), Telegram and Instagram channels, though some ask you to share a post or answer a question.
Rakeback is the stand-out feature. Most sweepstakes sites pay loyalty rewards daily or weekly, but Rainbet.us lets you claim rakeback every 15 minutes. If you play long sessions, claim it during the session rather than leaving it to build up.
Rainbet.us Coin Packages and Purchase Methods
You never have to buy anything at Rainbet.us. If you do, packages start at $15. That’s also the minimum for the TWRBUS first-purchase bonus. Most packages include bonus Rainbet Cash, but some don’t, so check before you buy:
| Package Price | Gold Coins | Bonus Rainbet Cash |
|---|---|---|
| $15 | 15,000 | 15.03 |
| $25 | 25,000 | 25.06 |
| $50 | 50,000 | 50.12 |
| $75 | 75,000 | None |
| $100 | 100,000 | 100.25 |
| $150 | 150,000 | None |
| $200 | 200,000 | 200.50 |
| $250 | 250,000 | None |
| $300 | 300,000 | 300.75 |
| $500 | 500,000 | 501.25 |
| $750 | 750,000 | 751.87 |
| $1,000 | 1,000,000 | 1,002.50 |
Gold Coin purchases are capped at $9,000 a day. Set a much lower personal limit and stick to it.
| Method | Type | Processing |
|---|---|---|
| Visa / Mastercard | Card | Instant |
| Apple Pay / Google Pay | Mobile wallet | Instant |
| BTC, ETH, LTC, USDT, SOL and more | Crypto | Under 2 minutes after one confirmation |
| MetaMask / Phantom (Direct Connect) | Crypto wallet | Under 2 minutes after one confirmation |
Rainbet.us is built around crypto and supports USDT on several networks. Card and mobile wallet purchases go through a third-party payment processor. Purchases appear on your statement as “Sweepstone,” so you won’t mistake the charge for something else.
How to Redeem Rainbet Cash for Prizes
Only Rainbet Cash you’ve won through gameplay can be redeemed. Gold Coins can’t. Follow these steps:
- Play your RC through. Use your Rainbet Cash at least once in an RC game. Rainbet.us may require up to three plays.
- Reach the minimum balance. Rainbet.us sets minimum and maximum redemption amounts. Check the redemption screen for the current minimum before you submit.
- Complete verification. Expect to provide a government-issued photo ID, proof of address and possibly a facial scan and SSN check.
- Submit your request. Choose your redemption method. Other publishers report that redemptions generally go back to the method you used for purchases.
Timing and limits: Rainbet.us says redemptions can take up to 30 days in some cases. Prizes of $600 or more may take longer and can be paid in more than one instalment. In Florida, redemptions are capped at $5,000 per monthly entry period, and any amount above that rolls into the next period. Processing fees may apply.
The simplest way to avoid delays is to verify your account before you need to redeem. Unverified accounts are the most common reason redemption requests get held.
Is Rainbet.us Available in My State?
Rainbet.us is open to legal US residents aged 18+ (or the local age of majority) everywhere except these 11 states:
| Restricted State | Restricted State |
|---|---|
| California | Michigan |
| Connecticut | Montana |
| Idaho | Nevada |
| Indiana | New Jersey |
| Louisiana | New York |
| Maine |
Rainbet.us’s Sweepstakes Rules also exclude any location “where otherwise prohibited.” State sweepstakes laws change often, so if your state’s status is unclear, confirm it with Rainbet.us support before you buy coins.
Is Rainbet.us Legit?
Rainbet.us is run by Sweepstone Ltd (company number HE 484722), based in Nicosia, Cyprus. The site describes itself as a free-to-play social casino using the sweepstakes model. Its Sweepstakes Rules are governed by Delaware law.
Here’s what we checked:
| Trust Check | What We Found |
|---|---|
| Published rules | Sweepstakes Rules, Terms, AML and Complaints policies |
| No purchase necessary | Stated on site; buying coins doesn’t improve chances |
| Fairness | Provably fair Originals; games audited by Game Check |
| Account security | SSL encryption and two-factor authentication (2FA) |
| Identity checks | KYC before any prize redemption |
| Support | 24/7 live chat (voice notes supported); email replies averaging around two hours |
| Complaints | Acknowledged within two business days; complex cases up to 30 days |
The platform is brand new, so it doesn’t have a long US track record yet. Read the redemption terms first and verify your account early.
What Can You Play at Rainbet.us?
Rainbet.us lists 7,000+ games from 40+ providers. That makes it one of the largest lobbies in the US sweepstakes market. The lobby is split into Slots, Originals and Live tabs, with search, provider filters, a New Releases section and a Random Game button.
| Category | What’s Included |
|---|---|
| Slots | 4,200+ titles from Hacksaw Gaming, Nolimit City, Booming Games, Betsoft, Thunderkick, AvatarUX and more |

Play Responsibly at Rainbet.us
Sweepstakes casinos are for entertainment. Gold Coins and Rainbet Cash aren’t a way to make money, and you shouldn’t buy coins you can’t comfortably afford. Rainbet.us offers these tools:
| Tool | What It Does |
|---|---|
| Loss limit | Caps the amount you can spend |
| Cool-off period | Pauses gameplay for a short, set period |
| Self-exclusion | Blocks access for 90 days minimum, or permanently |
| 24/7 support | Live chat for help with limits and account controls |
Once you start a self-exclusion, you can’t reverse it before the chosen period ends. Set personal budget and time limits before every session.
