Duelbits is a crypto casino and sportsbook launched in 2020, offering casino games, in-house originals, and a full sportsbook covering esports and traditional sports.

Yes — it's dual-licensed under Curaçao and, for the UK site, the UK Gambling Commission, a genuinely top-tier regulator. Trustpilot sentiment is mixed (around 3.0-3.3/5) with some withdrawal-delay complaints, so it's legitimate but not friction-free.

Is Duelbits Licensed?

Yes, under Curaçao licence OGL/2024/1507/0838, and the UK-facing version additionally holds a UK Gambling Commission licence.

How fast are withdrawals on Duelbits?

Many users report smooth withdrawals, but delayed withdrawals and refund-handling issues are a recurring complaint on Trustpilot, so don't assume every cash-out will be instant.

PROS

Dual-licensed — Curaçao (OGL/2024/1507/0838) for the main site, plus a UK Gambling Commission licence for the UK version, which is a genuinely top-tier regulator rarely seen in this niche
Established since 2020 with high-profile sponsorships (Conor McGregor, Luis Suárez, Aston Villa FC) signalling real financial backing
Broad catalogue: casino slots, in-house originals, a full sportsbook covering CS2, Dota 2, League of Legends, and traditional sports, plus a VIP club and referral program
Strong security: SSL encryption throughout, on-chain crypto transactions with no stored payment credentials, and 2FA

CONS

Trustpilot sentiment is mixed rather than strong — around 3.0 to 3.3 out of 5 — with specific complaints about refunds and delayed withdrawals
The UKGC licence applies specifically to the UK-facing version of the site, not necessarily every version players outside the UK access
As with most crypto casinos in this niche, standard caution applies around bonus wagering requirements
Sponsorship-heavy marketing spend is a sign of financial backing, but it's not itself a substitute for checking the platform's own track record with your specific payment method

Review

Duelbits is a crypto casino and sportsbook operated by Liquid Entertainment N.V., launched in 2020 and licensed under Curaçao (OGL/2024/1507/0838), with the UK-facing version additionally holding a licence from the UK Gambling Commission — a notably stronger regulatory backing than most sites in this niche, which typically rely on Curaçao or Anjouan alone.

The platform covers a lot of ground: casino slots and in-house originals, a full sportsbook that includes esports (CS2, Dota 2, League of Legends) alongside traditional sports, a VIP club, and a referral program. High-profile sponsorship deals with Conor McGregor, Luis Suárez, and Aston Villa FC point to a well-capitalized operation rather than a fly-by-night site.

Security fundamentals are solid — SSL encryption site-wide, on-chain crypto transactions that don't require storing payment credentials, and 2FA. Trustpilot sentiment, however, is genuinely mixed rather than glowing: ratings sit around 3.0 to 3.3 out of 5, with specific complaints about refund handling and withdrawal delays showing up often enough to be a real pattern rather than isolated noise.

Duelbits' licensing profile and financial backing put it a notch above most sites on this list in terms of formal legitimacy, but the withdrawal-delay complaints mean it's not without friction. A reasonable choice if you want a well-funded, broadly-licensed operator — just don't expect every cash-out to be instant, and keep an eye on refund handling if a dispute comes up.

About highlighted.gg

What is highlighted.gg?

highlighted.gg is an independent review platform for CS2 gambling sites: case opening, case battles, skin upgraders, crash, roulette and skin marketplaces. Every review is researched against public sources and scored with the same published rubric — games and design, bonuses, payments and support — so ratings are comparable across sites.

We explain exactly how we rate on our methodology page, and our editorial policy covers how affiliate links and promo codes are handled. When a site gives us no way to verify ownership or licensing, the review says so.

How we review sites like DUELBITS

Our DUELBITS review follows the same checklist as every CS2 case opening site we cover: what games it runs, whether its provably fair system can actually be verified, how deposits and skin withdrawals behave, what the bonus terms really say, and whether the operator publishes ownership and licensing information.

Sub-scores on this page feed the overall rating, and the promo code was last verified on 2026-08-13. If something changes — codes, bonuses, ownership — the review gets updated, not re-dated.

How to check if a CS2 gambling site is provably fair

“Provably fair” only means something if you can re-compute the roll yourself. A legit CS2 gambling site publishes a server seed hash before you bet, lets you set your own client seed, and reveals the server seed after rotation so every case opening, battle or upgrade can be re-derived.

You can verify any supported site's rolls in your browser with our free provably fair verifier — no signup, everything runs locally. Our blog walks through the math with worked examples.

CS2 gambling promo codes and bonuses

Most CS2 case opening sites offer a signup bonus — free balance, free cases or a deposit boost — activated with a promo code. Codes change and bonus terms carry wagering requirements, so we re-verify the codes in our reviews and date-stamp them.

The current DUELBITS code is on this page, and every active code we track is collected on our promo codes hub with the terms decoded.
