SweepState's editorial team documents operator terms, state-availability changes, and player-facing policies using a published methodology and source-first review process.
Methodology: We use documented account, product, redemption, and support checks where metadata exists, and we label reviews more cautiously when those records are incomplete. Official operator terms, support responses, and relevant public or regulatory sources are used as supporting evidence. Public user reports may trigger follow-up review, but they do not replace source-backed verification. Read our full review methodology.
Direct account test documented. SweepState has dated internal account-flow notes for this review. Public pages show only redacted status fields, not account or transaction records.

Compare Rainbow's End with similar sweepstakes casinos rated by our team.
Yes, Rainbow's End is a legitimate sweepstakes casino operated by Big Sky Gaming LLC. It uses SSL encryption, requires KYC verification before cashouts, and operates under US promotional sweepstakes law. We found no major red flags or controversy history during our review.
Rainbow's End is available in 38 US states. It is prohibited in 12 states: California, Connecticut, Idaho, Louisiana, Michigan, Mississippi, Montana, Nevada, New Jersey, New York, and Washington. It is also not available in any Canadian provinces.
Rainbow's End is a newer, smaller site. Chumba Casino has a larger brand, a bigger game library, and only restricts 4 states. Rainbow's End has a longer prohibited list (11 states) and slower reported redemption times. However, both sites have a 1x playthrough requirement and a similar first-purchase cost per Sweeps Coin.
Redemption processing times for Rainbow's End are reported to be between "up to 48 hours" and "up to 5 days." This is slower than competitors like WOW Vegas (1-3 business days) or Stake.us (minutes for crypto). Players should plan for a several-day wait.
The welcome bonus is 7,500 Gold Coins and 0.5 Sweeps Coins after you verify your email address. There is also an email-reply bonus of 10,000 GC and 5 SC if you respond to a welcome email within 48 hours of registering. No deposit or the offer.
No, Rainbow's End does not have native iOS or Android apps. You access the casino through a mobile web browser on your phone or tablet. The site is optimized for mobile browsers and offers the same features as the desktop version.
We found conflicting reports: one source says 50 Sweeps Coins, another says 100 Sweeps Coins. Until the casino clarifies, you should be prepared for a minimum threshold in that range. For comparison, Chumba Casino's minimum is 100 SC, and WOW Vegas's is 50 SC.
Rainbow's End games come from providers including Betsoft, BGaming, Playson, Relax Gaming, Habanero, RubyPlay, 3 Oaks, FantasmaGames, and Four Leaf Gaming. Notably, Pragmatic Play games are not available on this platform.
You must wager any bonus Sweeps Coins you receive exactly 1 time before they can be redeemed for cash prizes. All games contribute 100% to this requirement. This 1x playthrough is standard and player-friendly.
Rainbow's End mentions a VIP program exists, but specific details about tiers, benefits, and requirements are not published on the site. This lack of transparency makes it impossible to evaluate its value compared to detailed programs at casinos like McLuck or Pulsz.
You can purchase Gold Coins using Visa, Mastercard, Apple Pay, and Google Pay. Redemptions of Sweeps Coins for cash prizes are processed back to cards. The minimum purchase is tied to the bonus packages: $5 or $20.
You can get free SC through the no-deposit welcome bonus (0.5 SC), the daily login bonus (0.10 SC), the email-reply bonus (5 SC), and by submitting a mail-in request (2 SC) as a "No Purchase Necessary" alternative method of entry.
