Casino review
Duelbits review
Casino and sportsbook with published rakeback rates and 12 originals, licensed in Curaçao.
A Curaçao-licensed casino and sportsbook launched in 2020 that publishes more of its rakeback maths than any rival here: 10 percent instant plus 5 percent daily, weekly and monthly, all of house edge. Per-coin minimums and withdrawal times are documented, but it prints three different licence numbers and offers no deposit limit tool.
Plain link, no affiliate agreement. CoinHero receives nothing when it is used.

The short version
Duelbits is the most transparent of these operators about rewards. Its help centre sets out rakeback as 10 percent of house edge instantly plus 5 percent daily, weekly and monthly, and explains how sports wagers are counted. Its fees article gives a deposit minimum, a withdrawal minimum and an expected time for every coin and network, and says Duelbits charges no withdrawal fee of its own. It also states the rough threshold for enhanced verification, about EUR 2,000 in cumulative deposits or withdrawals, which most operators keep to themselves.
The paperwork around it is less tidy. Three different licence numbers and two registered addresses appear across its pages, the Crash house edge is given as 1 percent in one place and 5 percent in another, and there is no deposit limit tool. The terms exclude Australia, the United Kingdom and the United States.

What Duelbits is
Duelbits launched in 2020 and is run by Liquid Entertainment N.V. in Curaçao, with a Cypriot service company handling payments and support. It is a full casino and sportsbook with 12 originals, among them its own Dice Duels and Duel Poker, 80-plus studios, a live casino and a sportsbook with esports, and its brand leans on sports sponsorships. The site runs in ten languages and has no native app.
Its documents have not been kept in step. The terms and help centre give licence OGL/2024/1507/0838 from the Curaçao Gaming Authority; the homepage FAQ and older policy pages give two other numbers, and the terms give a different registered address from the footer. The current licence number is the one used here.
Deposits, networks and buying crypto
The fees and limits article covers 13 coins with their networks, minimums and times. USDT runs on Tron, Ethereum and BNB Smart Chain, USDC on Ethereum and Solana, and XRP needs a destination tag. Deposit minimums vary by route rather than coin: none for most, $1 for USDC on Solana, $10 for USDT on BNB Chain and $50 for USDT on Ethereum. There is no deposit maximum. The networks guide explains why the route matters as much as the coin.
For fiat, Duelbits offers a Buy Crypto option in US dollars or euros through a third party it does not name, and regional methods: PIX, Interac, cards and Revolut in Europe, JCB in Japan and UPI in India.
Verification
Duelbits asks only for email verification at sign-up and before a withdrawal. It is unusually specific about what comes next: enhanced checks generally apply once cumulative deposits or withdrawals reach about XCG 4,000, roughly EUR 2,000, with verification levels 1 to 5 unlocked by activity or at the operator's discretion. Documents run from ID and proof of address to proof of wallet ownership and, for high-volume players, source of funds. Reviews usually take up to 24 hours, though AML reviews can take longer. Two-factor authentication by authenticator app is optional and strongly recommended. The verification guide covers how to prepare.
Withdrawals
Duelbits charges no withdrawal fee of its own; the network fee is shown below the amount. Minimums are published per coin, from $10 for most routes to $50 for Bitcoin, Ethereum and stablecoins on Ethereum, and there is no maximum. At least 10 percent of each deposit must be wagered before withdrawing. Expected times are given per coin: seconds for USDT on Tron, 5 to 10 minutes for Ethereum, 10 to 30 minutes for Bitcoin, a few minutes for the rest. The homepage says instant, the terms say near-instant; the fees table is the realistic guide. We have not measured a withdrawal.
Games, sportsbook and fairness
The originals page lists 12 house games, from Crash and Plinko to Dice Duels, Duel Poker, scratch cards and a lottery. Duelbits publishes the verification code for ten of them: most use SHA-256 over your server seed, client seed and nonce; Duel Poker and Roulette use a daily public seed; Crash uses a five-million-hash chain seeded with a Bitcoin block hash. The originals page states a 1 percent house edge for Crash while a recent help article says 5 percent; ask support before relying on either. The provably fair guide explains the checks.
The live casino offers 100-plus tables from Pragmatic Play Live, Iconic21, Playtech and Ezugi, and the sportsbook covers 30-plus sports including esports and motorsport.
Rewards and offers
Ace's Rewards is open to every player and its rates are published: 10 percent of house edge back instantly, and 5 percent each daily, weekly and monthly, for 25 percent of house edge in all, plus level-up bonuses of up to 12.5 percent. On a game with a 1 percent edge, that is 25 cents back for every $100 wagered, before level bonuses. The invitation-only VIP Club adds a personal manager, priority withdrawals and cashback. For new players, the casino offer is up to 250 free spins on a first deposit of $20 or more, with the spin count scaling from $50, and the sportsbook offer is a free bet up to $100 after wagering the deposit five times. The bonus guide shows how to value both.
Support and player protection
Live support runs 24/7 alongside email and a help centre. Self-exclusion from casino, sportsbook or both is available for 1 week, 1 month, 6 months or permanently, starting with an immediate 24-hour cooling-off, and is requested through chat or email. Duelbits says plainly that it does not offer configurable deposit limits, and no time limits or reality checks are documented. Players who need limits should look elsewhere or use the blocking software Duelbits links to.
Who it suits, and who it does not
Duelbits suits a player who wants to know exactly what rakeback they are earning, clear per-coin minimums and a known verification threshold. It does not suit anyone in its 23 restricted territories, including Australia, the United Kingdom and the United States, or a player who relies on deposit limits.
What we have not tested
We have not opened an account, deposited, withdrawn or contacted support. Duelbits loaded from our Australian connection without a region notice, although its terms exclude Australia; its help centre and policy pages were read live on 26 September 2026. Where Duelbits' own pages contradict each other, the review says which it follows.
