Duel Slot Games
Slots on Duel come from third-party studios such as Pragmatic Play, Hacksaw Gaming and Relax Gaming. Each game page shows a house-edge badge, and Duel returns half of that edge to the player as instant rakeback. This guide explains what those numbers mean, lists the 32 games we checked on the live pages, and shows the 11 games we tested with real money.
The short version: across the checked games the displayed edge runs from 3.00% (Iron Bank) to 3.93% (Duck Hunters), the average is 3.52%, and 31 of 32 titles carry a bonus-buy option. The rakeback claim held in every test — $12.47 accrued on $700.00 wagered, reconciled to the cent, withdrawn with no wagering requirement.
RTP and house edge are long-run averages, not a forecast for your session. No selection method removes the casino advantage, and rakeback only reduces the theoretical cost of play.

Field data
Eleven Games, Real Money, Every Cent Reconciled
In July 2026 we played eleven slots on one funded account, logged every spin, and compared the rakeback Duel credited with the amount the badge predicted. The credited total came to 1.78% of turnover — half of an average 3.56% edge across the tested games. The rakeback was then withdrawn with no wagering requirement attached.
Gates of Olympus 1000badge 96.50%- Sweet Bonanza 1000badge 96.55%
- Le Banditbadge 96.4%
- Duck Huntersbadge 96.07%
- Sugar Rush 1000badge 96.53%
- The Dog House Megaways 1000badge 96.5%
- Fist of Destructionbadge 96.35%
- Wanted Dead or a Wildbadge 96.43%
- Gates of Olympus Super Scatterbadge 96.55%
- Big Bass Splashbadge 96.71%
- Zeus vs Hadesbadge 96.14%
The tests also settled a question the badge alone cannot answer. On games with several RTP modes, the figure on the badge was the highest mode in every game where we read the full list, nine of the eleven — nine modes on Duck Hunters, six on Zeus vs Hades — and the rakeback ran off that figure. Base play can sit slightly below it: Sweet Bonanza 1000 shows 96.55% while its base game is 96.53%. Le Bandit had a genuine gap between badge and rules; on Fist of Destruction an apparent gap turned out to be rounding. Each cover opens the spin log, the ledger and the limitations of that test, and the rules for all of them are on the methodology page.

The whole spread is under one percentage point. That is the practical takeaway for a player choosing between these titles: on Duel the difference in theoretical cost between the "best" and "worst" game on this list is $0.93 per $100 wagered, and rakeback halves it. Volatility, feature design and stake size will shape your session far more than the edge column.
Reading a game page
How to Read a Duel Game Page in Four Steps
1. Find the badge
Open the game inside the lobby. Below the title Duel lists the studio, the category and a percentage — that percentage is the house edge, not the RTP. Every game in the table above was read this way.
2. Turn it into RTP
Implied RTP = 100% − house edge on the badge
A 3.50% badge means a 96.50% theoretical return; a 3.00% badge means 97.00%. Both are averages over millions of spins. A single session on a high-volatility title can finish far above or far below either figure.
3. Open the in-game information screen
Many slots publish several RTP values — one for base play, others for ante bets or feature buys. In our eleven tests the badge always matched the highest of those values. If you play the base game, expect the base-game figure, which can sit a few hundredths below the badge.
4. Work out the rakeback
Duel credits half of the badge edge back to you as you wager. On a 3.50% game, $100 of turnover has a theoretical cost of $3.50 and earns $1.75 of rakeback, so the effective edge is 1.75% and the effective RTP 98.25%. The credit is instant and was withdrawable without a wagering requirement in every test.
What rakeback does not doIt lowers the average cost of play. It does not change the odds of any spin, soften volatility or turn a losing session into a winning one. Treat it as a discount, not an edge.
Where to go next
Pick a Page by What You Are Looking For
The lowest displayed edge
Iron Bank at 3.00%, Barbarossa Dragon Empire at 3.27% and Big Bass Splash at 3.29% lead the checked set. The gap to the median is small, so this list is a tie-breaker between games you already like, not a reason to play something you don't.
Bonus-buy games
Thirty-one of the 32 checked titles let you pay a multiple of the stake to enter the feature directly. The buy cost and the RTP of the bought feature are shown inside the game, and they differ from the base game — check both before you use the option.
A particular studio
Pragmatic Play accounts for fourteen of the checked games, Hacksaw Gaming for seven, Relax Gaming for five and Nolimit City for three, with Reel Kingdom, Play'n GO and Peter & Sons confirmed by one title apiece. The studio page shows which of them display an edge and where we have test data.
The rakeback maths
Why 50% of the edge is credited, how the accrual matched the badge on every test, and what changes when a game has more than one RTP mode. The page carries the summary table of all eleven tests.
Two kinds of games
Slots Are Not Duel Originals
The Duel lobby mixes two things. Slots are built by outside studios — reels, free spins, multipliers and feature buys follow the studio's own maths. Duel Originals are in-house games such as Mines, Plinko, Dice and Crash, with simpler mechanics and their own provably fair verification.
This site covers the slots. Originals have a different edge structure and a different verification model, so their numbers are not comparable with the table above, and we do not put them in the same list.
Brand clarity
Not to Be Confused With Duelz
If you searched for "duel slots", you may have meant either of two brands. This site describes Duel.com — the crypto casino whose badges and rakeback are covered above. Duelz is a separate, unrelated operator with a similar name and a different licence, market list and games library. Nothing on this site applies to Duelz.
Access
Where You Can Play, and What We Don't Do
Duel restricts a number of countries, and the list changes. Rather than copy a country list that may already be outdated, we point you to the current rules: read Duel's Terms of Service before registering or depositing, and confirm that your country is not excluded.
We do not explain how to reach Duel from a restricted country, and we recommend against using a VPN or proxy to try. Masked-location access breaks the terms, and the usual consequence is a frozen account at withdrawal time.
Method
How the Figures on This Site Were Obtained
The catalog was built by opening each game page on Duel and recording the studio, category, badge and bonus-buy option on the date shown. Eleven games went further: we wagered real funds, logged every spin, reconciled the balance ledger and compared the credited rakeback with the badge prediction. Where a value could not be read from the live page or the game, it is marked "not verified" rather than filled from another site.
The figures are dated because they expire. Studios ship new RTP versions, Duel updates its lobby, and reward terms change. When the live page and this site disagree, the live page is right and this site needs an update.
FAQ
Frequently Asked Questions
Does Duel show the RTP of its slots?
It shows the house edge on the game page. Subtract it from 100% to get the implied RTP: a 3.50% badge is a 96.50% game. On the 32 games we checked the badge ranged from 3.00% to 3.93%.
How much rakeback does Duel pay on slots?
Half of the badge edge, credited as you play. Our eleven tests accrued $12.47 on $700.00 wagered — 1.78% of turnover — and each accrual matched the prediction to the cent. The credited amount was withdrawn without a wagering requirement.
Is the badge the RTP you actually get?
It is the highest RTP mode the game publishes. If you play the base game rather than an ante or feature-buy mode, the return can be a few hundredths of a point lower — Sweet Bonanza 1000 is 96.53% in base play against a 96.55% badge. The rakeback is calculated from the badge either way.
Which Duel slot has the lowest house edge?
Iron Bank by Relax Gaming, at 3.00%, among the games we checked. The next are Barbarossa Dragon Empire at 3.27% and Big Bass Splash at 3.29%. The full list is small and dated, so a lower-edge game may exist that we have not recorded yet.
Do bonus buys change the RTP?
Usually, yes — the bought feature has its own RTP, listed in the game's information screen, and it can be higher or lower than base play. A bonus buy also compresses many spins of variance into one purchase, so it raises risk per dollar even when the RTP is unchanged.
Are Duel and Duelz the same casino?
No. They are two unrelated operators. Everything on this site refers to Duel.com.
Can I use a VPN to play on Duel?
Don't. Duel's terms prohibit masked-location access, and accounts opened that way are typically frozen when a withdrawal triggers verification. Check the restricted-country list in the terms instead.
How current is this data?
Page checks date from 29 June 2026 and the wager tests from 17 July 2026; each row in the catalog carries its own date. Anything on the live game page that differs from this site takes precedence.
