How Dice Works
Dice is the game that built the crypto-casino genre, and Duel strips it back to essentials. You get a slider from 0 to 100, you choose whether the roll must land over or under your target, and the interface instantly shows your win chance and the matching multiplier. Push the win chance up and the payout shrinks; drop it down and the payout balloons. It is the clearest risk-reward dial in the whole catalogue.
Because the house edge is removed, the math reflects true probability rather than a tilted table. A 50% win chance pays close to 2x, not 1.96x after a hidden cut. Over a long session you fight variance alone, which makes Dice the lowest-variance way to feel out how Duel's fairness actually works.

Provably Fair
Every Duel Original, including Dice, is provably fair through a dual-seed system. Before a round, the server generates a seed, hashes it and shows you the hash. You add your own client seed, and a nonce counts each bet. Those values run through HMAC-SHA256 to produce the result, and once the round ends the server reveals the original seed so you can re-run the hash and confirm nothing changed after you bet.
You never have to trust Duel on Dice. The dual-seed commitment means the outcome is locked before your bet and revealed for verification afterwards, so the published return reflects real, checkable odds rather than a promise.
Dice FAQ
Is Duel Dice provably fair?
Yes. Dice uses Duel's dual-seed system: the server commits to a hashed seed before the round, you provide a client seed, and after the round the server seed is revealed so you can verify the result yourself with HMAC-SHA256.
What is the RTP and house edge of Dice?
Dice has a published RTP of 100% and a house edge of 0% (0.1% default outside zero-edge window). Duel earns through a per-round commission and rakeback rather than a margin baked into the game math.
