Originals and bonus rules
Duelbits vs Metaspins: numbered bonus rules against printed reward clocks
Metaspins' terms, last updated 29 July 2026 and read on 2 September 2026, cap bets at 5 USDT a round while a bonus runs and count only slots towards wagering. Duelbits' general promotion terms could not be read in the archive, but its offer pages print their own rules, and its help centre prints when each kind of rakeback bit expires.
Metaspins numbers its bonus rules, which is rarer than it should be: section 14 of its terms, read on 2 September 2026, caps bets at 5 USDT a round while a bonus is live (14.11), counts only slots towards wagering (14.13.1) and allows one bonus at a time (14.17.1). Duelbits documents a different part of the loyalty picture. Its help centre prints the exact hour each kind of rakeback bit expires. Both run in-house games next to a sportsbook, and we have deposited at neither, so this comparison is built from their own pages and the registers.

Licence: a certificate against a line in the terms
Duelbits' Curaçao certificate, read 26 August 2026, names Liquid Entertainment N.V., company number 153298, licence OGL/2024/1507/0838, granted 01/11/2024, status Active, and its footer repeats the company. The Anjouan register has no entry for duelbits.com; a second domain, duelbits.io, is listed there under Elevated Entertainment Ltd (ALSI-112310013-FI5, valid to 12 October 2026, read 11 September 2026).
Metaspins prints its own licence line in clause 1.1 and again in the footer: the Government of the Autonomous Island of Anjouan, licence ALSI-202606048-FI2, with 3-102-959384 SRL, a Costa Rica company, as the operator. Our register records, read 26 August 2026, show that Anjouan number for metaspins.com in the name of 3-102-959384 SRL, valid to 29 June 2027, and a separate Curaçao certificate, OGL/2024/1063/0437, held by Metaspins N.V., company number 160102, marked Active. The terms we read mention only the Anjouan licence, so we give both sources and say which says what.
Games: two sets of Originals
Duelbits' welcome article, archived 24 January 2024, claims over 3,000 games from studios such as Evolution Gaming, Pragmatic Play, Play'n Go and Relax Gaming, and names six in-house titles: Crash, Roulette, Dice Duels, Dice, Plinko and Mines. Tap Trading appeared in its front-page sidebar, marked NEW, on 26 August 2026. What each Duelbits original is, per its own pages, is on Duelbits Originals.
Metaspins prints no total for games or studios. Its homepage strip on 2 September 2026 gave per-studio counts instead: Pragmatic Play 724, BGaming 261, Voltent 225, Hacksaw 207, Yggdrasil 181, Booming 176, Evolution 148, NoLimit City 135, Penguin King 104 and Popiplay 88. It has a Metaspins Originals line too, though the pages we read do not list its games.
Sportsbook
Metaspins keeps a Sports section in its navigation, a separate sports promotions page and a “100% Sports Welcome” listed without figures. Sports bets count for nothing towards casino bonus wagering under clause 14.13.1. Duelbits' sportsbook help collection, archived 14 August 2025, covers single and multi bets, totals, soccer, tennis, settlement questions and a cash-out it does not guarantee at all times. Neither prints a maximum stake in the documents we read; Duelbits' 2022 interface file gives a minimum stake of 0.05.
Rewards
Duelbits splits Ace's Rewards into four kinds of bits and, per its help centre archived 15 May 2025, gives each a clock: instant bits never lapse, daily rakeback goes at 00:00 UTC each day, weekly bits every Monday and monthly bits on the first of the month. An article archived 21 January 2025 adds extra Monday rakeback from casino and sportsbook for VIP players. The only rates Duelbits printed are in its 2022 interface file, archived 18 April 2022: 10% of the house edge for instant rakeback and 5% each for daily, weekly and monthly; a New Rakeback System article appeared in its help centre by August 2025, text not archived, so today's rates may differ. The full scheme is on Duelbits rakeback and VIP.
Metaspins' terms mention rewards and NFT revenue share only once, in clause 4.2, which says every deposit, reward and revenue share must be wagered at least once before withdrawal. We read no rate and no expiry for its loyalty scheme.
ID and withdrawals
Clause 9.7 says Metaspins must verify your age and must verify your identity “upon your gambling reaching a certain threshold”, while keeping discretion to do it at any time and to lock withdrawals until it is done. The threshold is never given. Clause 9.10 gives 30 days to comply with a request, or at least to acknowledge it, and failure can mean closure and confiscation of the balance; clause 9.9 covers accounts whose details turn out not to match. Registration itself asks only for an email address and a password.
Section 12 states no processing time; it allows a hold “for the time needed to check your identity” (12.3). Withdrawals go back through the deposit method (12.2) and in the coin you deposited (11.3). Clause 12.5 says the maximum may depend on the payment method and reserves monthly instalments, naming no amount for either. The homepage promises “0% fees” while clause 12.2 says withdrawals can incur charges; both are Metaspins' own words. A dormant account is charged 10 US dollars after 12 months (13.1).
Duelbits touches the same subject from the other end. Its withdrawals collection, archived 14 August 2025, has an article titled “Does Duelbits charge Withdrawal Fees?” whose answer was not archived, so neither brand gives us a fee figure we can rely on. No Duelbits text we read prints an ID trigger, a time or a limit.
Bonuses
Metaspins advertises a 100% welcome bonus up to 1 BTC. No wagering multiple appears in anything we read, and the welcome-bonus page redirects to the homepage. Clause 14.12 sets minimum bonus amounts in nine currencies and says smaller bonuses “will be nullified”. Duelbits' help centre, archived 21 January 2025, points to weekly casino and sportsbook promotions and Discord giveaways. Its offer pages carry their own terms: the casino welcome, archived 3 February 2026, pays 500 free spins on Pragmatic Play slots in three steps and says “Your winnings don't have any wagering requirements”; the sports welcome, archived 23 December 2025, releases a free bet of up to $100 once 5x the deposit is wagered. Its general promotion terms could not be read. How other operators number these rules is on bonus terms compared.
Who should pick which
- Metaspins suits a slots player who wants the bonus rules numbered before accepting an offer, and who is happy to leave originals and sports out of the wagering.
- Duelbits suits a player who spends most time on in-house games or the sportsbook and wants rakeback with written expiry times rather than a bonus that only slots can clear.
- More options are on our list of casinos like Duelbits, and every matchup is on the Duelbits comparison hub.
