Quick Verdict

What Is Duelbits?

Duelbits is a cryptocurrency casino and sportsbook operated by Liquid Gaming N.V., launched in 2020. The platform is built around three pillars: a casino with Provably Fair Original games and a full third-party slot and live casino library, a comprehensive sportsbook, and a rakeback reward system that returns real cash to players continuously.

Duelbits is a crypto-first platform, all balances are held and wagered in Bits, the platform's internal unit of value. Deposits can be made in cryptocurrency or, depending on your region, via fiat payment methods that convert your currency into crypto on arrival. All withdrawals are processed in cryptocurrency regardless of how you deposited.

Since launch, Duelbits has grown into one of the more recognisable names in the crypto casino space, with a community of players across multiple continents and a platform that continues to expand its game and sports offering.

Is Duelbits Legit? Licensing and Security

Duelbits operates under a Curacao Gaming Authority licence (GLH-OCCHKTW076092020), issued to Liquid Gaming N.V. You can verify this licence directly at cert.cga.cw.

Curacao licensing is the most common regulatory framework for crypto casinos. It requires operators to maintain game fairness standards, operate AML and KYC compliance programmes, and hold player funds responsibly. Duelbits has maintained a clean record since its 2020 launch with no publicly reported security breaches.

Security features:

• Two-Factor Authentication (2FA): Available in account settings. Adds a second verification step, a time-based code from an authenticator app, to your login process. Strongly recommended for all accounts and takes under two minutes to enable.
• SSL/TLS Encryption: All data transferred between your browser and the Duelbits servers is encrypted. Your personal information and transaction data are protected in transit.
• Cold Storage: Player cryptocurrency holdings are stored in cold wallets, offline storage inaccessible to external attacks. Duelbits maintains reserves to cover all player balances.
• Provably Fair: For Original games, every result can be verified by the player using cryptographic tools. This is a significantly higher standard of transparency than traditional online casinos offer.
• Bug Bounty Programme: Duelbits runs a security bug bounty scheme. If you identify a vulnerability, you can report it and be rewarded. Details are available on the Security page.
• A note on UKGC licensing: The UK Gambling Commission does not licence crypto-native platforms, this is an industry-wide position, not specific to Duelbits. Duelbits operates under its Curacao licence and lists the UK as a restricted territory accordingly. The same security protections apply to all players regardless of location.

Provably Fair: How It Works

Duelbits Originals use a three-component Provably Fair system:

• Server seed: A random value generated by Duelbits before the round starts. Its SHA-256 hash is shown to the player before play begins, so Duelbits cannot change the server seed after seeing your bets.
• Client seed: A random value provided by the player's browser, which you can change to any value you choose before a round. Because your client seed is unknown to Duelbits in advance, neither party can calculate the outcome before it happens.
• Nonce: A sequential counter that increments with each bet, ensuring each round produces a unique result even if seeds remain unchanged.

The outcome of each game round is generated by combining these three inputs using SHA-256 hashing. After the round, the server seed is revealed, allowing any player to confirm that the result matches the hash they were shown before playing.

All 10 Duelbits Originals support Provably Fair verification. An interactive sandbox allows you to verify any past game result at any time. Dice Duels additionally incorporates the EOS blockchain block ID as a further fairness input.

How to verify a round yourself:

1. Open any Duelbits Originals game and click the fairness or shield icon
2. Note the hashed server seed, your client seed, and current nonce
3. Optionally change your client seed before the round begins
4. Play the round, the unhashed server seed is revealed on completion
5. Visit the Fairness page, enter the three values into the sandbox, and it will reproduce the exact result independently
