Evidence

Return to player, by game type

Every figure carries a source. Where a headline RTP has conditions attached, the conditions are printed — an unconditioned “0% house edge” claim is not a fact, it is an advertisement.

Category	RTP	House edge	Range	Conditions & source
House originals	100.00%	0%	—	Zero edge applies up to a daily wager allowance and a per-bet limit. Bets above the limit, or placed after the daily allowance is used, incur a scaling house edge - Duel's own help text describes roughly 0.1% for the highest-volume players. Fun-mode play does not consume the allowance. Confirm your current limits in-product; they are account-specific. Duel's own published help content, read from the site's application bundle. Exact allowance figures are account-specific and not stated in the bundle. Source ↗ · checked 6 Aug 2026
Slots	96.50%	3.50%	94.0%–98.5%	Modelling assumption, not an operator disclosure. Third-party suppliers; RTP varies by title. Source ↗ · checked 6 Aug 2026
Sports	98.00%	2.00%	—	Sportsbook margin is not an RTP in the slot sense; it is an implicit overround on offered odds. Treated as ~2% for comparability. Modelling assumption. Nominal sportsbook margin for comparability only. Source ↗ · checked 6 Aug 2026

50% instant rakeback, no bonus at all

There is no wagering requirement because there is no bonus balance to clear — which is precisely why it survives our model intact. Duel pays back a share of the house edge on every bet, withdrawable immediately, in place of bonus credit released over time. Note the corollary: the zero-edge house games generate no house edge, so they generate no rakeback either. The value here is on third-party slots and live tables.

Game weighting

A weighting below 100% multiplies the money you must actually stake. Zero means the game cannot clear the bonus at all.

Slots 100%
House originals 100%

No expected value stated

No bonus balance and no wagering requirement. Value scales with your own volume, so a fixed-deposit EV would misrepresent it.
