Head to head
Duelbits vs Rainbet: a Curaçao certificate against a 72-hour ID clock
Rainbet gives players 72 hours to finish an ID check under clause 20.1 of its terms, and prints two welcome paths, one of them at 40x. Duelbits' archived help centre names no ID trigger, but it does print when each kind of rakeback bit expires.
Both sites run on clocks; they print them in different places. Clause 20.1 of Rainbet's terms, captured 2 September 2026, gives a player 72 hours to complete verification and gives Rainbet up to 7 business days to review it. Duelbits' help centre, archived 15 May 2025, sets expiry times for daily, weekly and monthly rakeback bits and lets instant bits build up without limit. Otherwise they sell the same thing: in-house games, a sportsbook, rakeback and a cashier that takes crypto, cards and gift cards. We have deposited at neither.

Licence: a certificate and a register entry
Duelbits can be looked up by domain: on 26 August 2026 the Curaçao portal returned duelbits.com under Liquid Entertainment N.V., company number 153298, licence OGL/2024/1507/0838, granted 1 November 2024, Active.
Rainbet is harder to place from its own pages. Clause 21.6 names “our licensing body Gaming Services Provider N.V.” as the place to take a complaint, and the footer carries a Licensed badge, yet no licence number appears in the footer, the terms or the AML page as captured on 2 September 2026. The footer gives an operator address on Anjouan in the Comoros, and the Anjouan register, read 26 August 2026, lists ALSI-152406029-FI2 for RBGAMING N.V., the company Rainbet names, valid to 13 June 2027.
One detail links the two: Duelbits' help centre, archived 24 January 2024, placed Duelbits under the Master License of Gaming Services Provider, the body Rainbet names in clause 21.6, before its own certificate was granted. What that certificate settles is set out on Is Duelbits legit?.
Games
Rainbet's homepage, captured 2 September 2026, claims “8,000+ casino games” from providers including Pragmatic Play, Evolution, Relax Gaming, Hacksaw Gaming, BGaming and NoLimit City. Its FAQ says Rainbet Originals run on provably fair logic, while Case Battles and EOS Roulette take their randomness from EOS blockchain blocks.
Duelbits' welcome article, archived 24 January 2024, claims over 3,000 games from Evolution Gaming, Pragmatic Play, Play'n Go, Relax Gaming and others, and lists Crash, Roulette, Dice Duels, Dice, Plinko and Mines as its own; the front page on 26 August 2026 added Tap Trading, marked NEW.
Both totals are the operators' own, written over two and a half years apart, so the gap says little about either lobby today.
Sportsbook
Rainbet runs its sportsbook on the same wallet as the casino, and its homepage says sports bets count three times in its Weekly and Monthly Races.
Duelbits' site description, archived 3 June 2026, promises odds on “50+ sports”, and a blog guide dated 22 May 2026 explains its esports markets, from match winner and map handicap to live in-play. Sports play feeds both loyalty schemes: Duelbits' Monday VIP perks add extra sportsbook rakeback (archived 21 January 2025).
Rewards and rakeback
Rainbet's homepage explains its “up to 70% back” as a stack: rakeback claimable every 15 minutes, three daily reloads, daily, weekly, pre-monthly and monthly bonuses, rank-up bonuses and RakeBoosts. The 70% covers all of that together; no single part carries a rate in what we read.
Duelbits documents what happens to unclaimed rewards. Its help article, archived 15 May 2025, says instant bits never expire, daily rakeback lapses at 00:00 UTC each day, weekly bits at 00:00 UTC on Mondays and monthly bits at 00:00 UTC on the first of the month. In its 2022 interface file, archived 18 April 2022, Duelbits put instant rakeback at 10% of the house edge and the rest at 5%; a New Rakeback System article appeared in 2025, and its text was not archived, so those rates may have changed. Rainbet's pages, as read, leave rakeback expiry unstated. The Duelbits side in full is on Duelbits rakeback and VIP.
ID checks and withdrawals
Rainbet, clause 20.1: KYC documents can be requested at any time to establish identity and location. Service, payments and withdrawals may be restricted if verification is not completed within 72 hours, the review can take up to 7 business days, and failing or refusing the check results in confiscation of funds. Documents named across clauses 20.1, 5.2 and 8.3 run from a government photo ID and a selfie holding it to a utility bill and a verification call.
Section 8 prints a minimum withdrawal of $15 per transaction, except on account closure (8.1), a 1x wager lock on crypto deposits (8.7), and payouts back to the method used to deposit (8.4). It sets no processing time. The homepage says withdrawals are typically sent within 5 to 15 minutes in normal conditions; that is Rainbet's claim, untested by us.
Duelbits leaves the archive thinner. Its help centre recommends email verification first (15 May 2025) and lists a “KYC Guidelines for Submissions” article under Withdrawals (14 August 2025) whose body was not captured. Its site description advertises “instant withdrawals” (3 June 2026), yet none of the archived text gives a time, limit or fee. Other operators' ID rules are side by side on ID checks compared.
Neither site has had our money; our two tests were at Vave, our advertiser, on 28 August 2026 and TrustDice in May 2026.
Bonuses
Rainbet's welcome offer sits in homepage copy without clause numbers, and you pick a path before the first deposit. The 40x path runs 100%, 50% and 100% over three deposits, each with 20 free spins on Sweet Bonanza, from a $30 minimum to $700 per tier, with 40x wagering on deposit plus bonus, a maximum bet of 2% of the deposit and slots above 97.4% RTP excluded. The other path pays up to 100% as you play, with no rollover and the same limits. The numbered terms add that the bonus cannot be topped up (9.4) and applies to a first account only (9.6).
At 40x, a $700 deposit matched at 100% asks for $56,000 in bets before the bonus is free.
Duelbits' help centre, archived 21 January 2025, names no welcome offer, only weekly casino and sportsbook promotions, Discord giveaways and Ace's Rewards, without printed wagering terms. A blog post dated 4 May 2026 adds daily and weekly leaderboards with $10,000 and $30,000 in prizes.
Who should pick which
Rainbet fits a player who wants a welcome offer with its terms on the page, EOS-based Case Battles and Roulette, and can answer an ID request within 72 hours.
Duelbits fits a player who wants a licence the Curaçao portal confirms for its own domain, Dice Duels or Tap Trading, esports markets, and rewards with written expiry times.
If neither fits, the rest of our Duelbits alternatives cover the same ground with different rules.
