About this Slot
Duel is an Ancient Rome-themed slot from Nocturnestudios with an RTP of 95%, high volatility and a maximum win of 24x.
The game uses a Battle Outcome payline system where you select a fighter to begin each battle. You then adjust a slider to set your preferred win chance percentage, which determines the multiplier applied to your stake. The multiplier is calculated as 100 divided by your chosen win chance, multiplied by 0.95.
During each battle, a random number is drawn from 0 to 99. Your selected fighter wins if the number falls below your chosen threshold, while the opposing fighter wins if the number exceeds it. If the random number matches your threshold exactly, the round results in a draw.
The multiplier ranges from 1.90x when you set a 50% win chance, up to 23.75x at a 4% win chance. A roll history feature displays your recent outcomes, colour-coded for easy reference.
