1

100% RTP
100% Return to Player means a game returns 100 cents for every dollar wagered, on average over many sessions. It indicates zero house edge. Duel promo codes unlock 100% RTP on Duel Originals games.

A

Affiliate Code
A code assigned to an affiliate partner or content creator. When a new user enters the affiliate code at registration, they receive enhanced benefits, and the affiliate earns a commission. DUEL5 and FUSE are Duel affiliate codes.

B

Bonus Code
Another term for promo code or referral code, often used interchangeably. A bonus code unlocks additional rewards at registration. At Duel, DUEL5 and FUSE function as bonus codes.

C

Cashback
A reward that returns a percentage of net losses to the player. Cashback differs from rakeback in that it is based on losses rather than rake generated. Duel promo codes offer rakeback, not cashback.
Crash Game
A game format where a multiplier increases from 1x until it "crashes." Players must cash out before the crash to win their wager multiplied. Crash games are a common game type within Duel Originals.

D

Duel Originals
Proprietary games developed exclusively by and for Duel.com. These titles — including crash games, dice variants, and card games — are only available on the Duel platform. With a promo code, Duel Originals have 100% RTP.

Rake
The fee or commission taken by a platform from each game, pot, or wager. Rakeback returns a percentage of this fee to the player. Understanding rake is key to understanding the value of a high rakeback rate.
RTP

A loyalty rewards structure that provides higher benefits to players who wager more. Enhanced Rakeback from promo codes may complement or stack with VIP rewards, depending on platform policy.

W

Wagering Requirement
A condition requiring a player to wager a specified amount before bonus funds can be withdrawn. Duel promo code rewards (rakeback and RTP) do not include traditional wagering requirements — they are structural benefits.
