Duel.com Casino Games

Duel.com offers in-house Duel Originals — Crash, Dice, Plinko, Mines, Blackjack, Keno, Castle Roulette, Video Poker, Limbo, Rock Paper Scissors, Groomers Van and Beef — plus third-party slots and live dealer tables from external studios. Originals are provably fair and run at 100% RTP within the daily zero-edge allowance; third-party games run at the provider's certified RTP with 50% rakeback on the house edge.

They describe the same maths from opposite angles. House edge is what the operator keeps; RTP is what the game pays back. A 97% RTP title has a 3% house edge. If you wager 10,000 total on that game, the expected long-run cost is roughly 300 — spread across many bets, not taken in one lump.

Each round starts at 1.00× and the multiplier increases until the game crashes at a randomly determined point. You place a bet before the round begins and choose when to cash out. If you cash out at 2.50×, you receive 2.5 times your stake. If the game crashes before you cash out, you lose the stake.

Use the slider or input field to choose your win probability — for example, 50% for a coin-flip equivalent or 25% for a longer-shot bet. The interface displays the payout multiplier that corresponds to that probability, and you choose whether the roll must land over or under the threshold. Adjust until you understand the trade-off between hit rate and payout size.

You choose how many mines to hide on the grid, place a bet, then click tiles to reveal gems or mines. Each safe tile increases your payout multiplier. Hit a mine and you lose the stake. You can cash out after any number of safe reveals to lock in the current multiplier — the decision of when to stop is the whole game.

You select a row count from 8 to 16 and a risk level, place a bet, and release a ball that bounces through pegs into a payout slot at the bottom. The slot's multiplier sets your payout. Results are provably fair: the seeds decide left or right at every row before the drop, and the slot is the number of rights.

The core rules are standard: beat the dealer with a total closer to 21 without busting; face cards count 10, aces 1 or 11; you can hit, stand, double or split. Duel's Zero Edge variant adjusts specific rules and payouts so correct basic strategy yields about 0% house edge — read the in-game rules panel, because the settings differ from a typical table.

Duel.com has Castle Roulette, an in-house provably fair Duel Original, alongside third-party and live dealer roulette tables in the casino lobby. They are different games: Castle Roulette is a multiplier wheel with 48 equally likely rolls, while provider tables are standard roulette with the usual house edge for their wheel type.
