Provably fair in-house games built for speed and transparency: Dice, Crash, Plinko, Mines, Blackjack and more.
Duel Originals are Duel Casino’s in-house games designed around provably fair verification (server seed + client seed + nonce).
They’re popular because gameplay is instant, rules are simple, and outcomes can be checked independently after each round.
Below is a practical breakdown of the key Originals and what each game is best for.
Choose win chance and roll under/over. Great for controlled variance and autobet sessions.
Multiplier climbs from 1x—cash out before it crashes. Use 1.5–2x auto cashout for lower variance.
Adjust rows and risk. Low risk for frequent hits; high risk for rare spikes.
Reveal safe tiles and cash out progressively. Best for bankroll management sessions.
Skill-based play with basic strategy. Lower variance than most originals.
High volatility. Not ideal for grinding, better for “big swing” sessions.
Pick numbers, watch draws. Simple and fast for casual play.

Use the server seed, client seed, and nonce in the verifier tool and confirm the outcome matches.
Dice or Plinko are the easiest to start with because variance and settings are adjustable.
