Nine studios, checked on the live pages
Duel Slot Providers
Nine slot studios have games we have opened and read on Duel: Pragmatic Play, Hacksaw Gaming, Relax Gaming, Play'n GO, Nolimit City, Backseat Gaming, Reel Kingdom, Peter & Sons and Red Tiger. Four of them have titles we played with real money. This page tells you what each studio's games cost on Duel, which of them we tested, and what the studio's habits mean when you read a game page.
The studio matters more than the casino for how a slot plays: it sets the maths, the volatility, the feature design and whether the bonus can be bought. What Duel adds is the badge on the game page and the rakeback on top — and those are the same for every studio. The lowest badge we have seen is Relax Gaming's Iron Bank at 3.00%, the highest Red Tiger's 5 Families at 4.31%.
Data as ofLobby checks: 26 June 2026. Catalog page checks: 29 June 2026. Wager tests: 17 July 2026. Libraries change; a studio or title not on the live lobby today is one we cannot vouch for.

Studios on Duel, by Lowest Badge Seen
"Badge range" is the lowest and highest house edge we have read on that studio's game pages — not the studio's full range on Duel. "Tested" counts games played with real money in our rakeback series; the game names link to the tests.
| Studio | Games we checked | Badge range | Tested | Feature buy | Checked |
|---|---|---|---|---|---|
| Relax Gaming | Iron Bank, Troll's Gold, La Fiesta, Wild Yield, Iron Bank 2, Shark Wash, Kraken's Cove, Money Cart 3, Midnight Marauder – ClusterBreaker | 3.00%–4.00% | 0 | Yes on the five catalogued titles | 2026-06-26 / 06-29 |
| Peter & Sons | Barbarossa Dragon Empire | 3.27% | 0 | Yes | 2026-06-29 |
| Reel Kingdom tested | Big Bass Splash | 3.29% | 1 | Yes | 2026-07-17 |

Badges for the catalogued titles are in the catalog row by row; the remaining lobby-checked titles were read for studio and badge range on 26 June 2026 and are not yet catalogued individually. Duel labels Reel Kingdom as its own studio even though Pragmatic Play distributes its games, so the two are listed separately here as they are on Duel.
Reading the table
What the Studio Tells You — and What It Doesn't
The studio predicts the badge band fairly well. Pragmatic Play sits between 3.40% and 3.86% on every game we read, Hacksaw Gaming between 3.57% and 3.74%, Nolimit City between 3.57% and 3.93%. Relax Gaming is the exception: it has both the lowest badge on the site and titles up to 4.00%, so its name alone tells you little. Across all nine studios the spread is 1.31 percentage points — $1.31 per $100 wagered before rakeback halves it.
What the studio predicts far better is how the game behaves. Nolimit City and Hacksaw Gaming build high-volatility games around bought features; Pragmatic Play's 1000-series titles carry ante bets that raise the RTP mode; Reel Kingdom's Big Bass Splash runs its feature buy at the same RTP as base play. None of that shows on the badge, all of it shows on the game's information screen, and it will shape your session more than the edge column.
Studio by studio
What We Know About Each Studio on Duel
Pragmatic Play
Fifteen games checked, six played with real money — the most of any studio here. Every badge we read sits between 3.40% (Sweet Bonanza) and 3.86% (Zeus vs Hades); the 1000-series titles cluster at 3.45–3.50%. All fourteen titles with a recorded badge offer a feature buy.
Two habits matter when you read a Pragmatic page on Duel. The rules screen publishes a separate RTP for every mode — base, ante, buy, super — and the badge quotes the highest of them; Sweet Bonanza 1000 shows 96.55% while base play is 96.53%. And the Hyperplay batch panel logs each spin with a running total bet, which is why our turnover reconciled to the cent on all six tests.
Hacksaw Gaming
Nine games checked, three tested. Badges run from 3.57% (Wanted Dead or a Wild) to 3.74% (SixSixSix); the seven with a recorded badge all offer a feature buy. These are high-volatility games built around their bonuses, and the buy option is how most people play them.
The studio's quirk: it prints RTP at mixed precision — one decimal in one place, two in another — so the badge and the rules screen can appear to disagree. On Fist of Destruction the gap dissolved into rounding once the accrual was read to eight decimals; on Le Bandit it was real and is documented in the test. If a Hacksaw badge and rules figure differ by a few hundredths, that is usually the reason.
Relax Gaming
Nine games checked, none tested yet. This is the studio with the lowest badge on Duel — Iron Bank at 3.00% — and also titles at 4.00%, the widest spread of any studio here. Iron Bank 2 sits at 3.50%, half a point behind the original, because Relax ships several RTP versions of its games and Duel's is not always the top one.
Practical consequence: never assume a Relax title's edge from another Relax title. Read the badge on each game. The five catalogued titles all offer a feature buy.
Nolimit City
Five games checked, one tested. Badges from 3.57% (Book of Shadows) to 3.93% (Duck Hunters) — the widest band of the four tested studios, and the top of it is the highest tested badge on the site. Duck Hunters is the game that revealed how Duel's badge works: it publishes nine mode RTPs, and the badge quotes the best of them. The rakeback follows the badge whichever mode you play.
Nolimit's Action Spins batch panel logs spins the way Pragmatic's Hyperplay does, so its turnover is easy to reconcile. Expect very high volatility and feature buys at large multiples of the stake — up to 600x on Soaked by Seamen, though Book of Shadows sells its tiers at 60x to 120x.
Reel Kingdom
One game, Big Bass Splash, tested with real money: 3.29% on the badge, 96.71% implied — the cheapest game we have played on Duel. Its feature-buy RTP equals base play, which makes it the simplest case in the series.
Duel lists Reel Kingdom as its own label even though the studio's games run on Pragmatic Play's platform. One title is enough to list the studio, not enough to describe it; treat the row as a single data point.
Play'n GO
Four games checked, none tested. Rich Wilde and the Tome of Madness has a 3.41% badge and is the only catalogued game on the site without a feature buy; the other three titles read in the lobby run up to 3.80%.
The studio ships several RTP versions of most titles, so a figure you know from elsewhere may not be Duel's. Read the badge.
Peter & Sons
One game, Barbarossa Dragon Empire, at 3.27% — the second-lowest badge in the catalog, from a small studio most players will not have searched for. Feature buy confirmed on the live page.
A recent release; the feature set is worth re-reading on the game page before you rely on the row.
Backseat Gaming
Four games read in the lobby — Diamond Mole, Shadow Strike, Pirate Bonanza 2, The Cursed King — in a narrow 3.64%–3.70% band. Feature-buy status was not checked and the titles are not yet in the catalog.
A small studio with consistent badges; the row exists so you know the games are on Duel, not because we can say much about them yet.
Red Tiger
One game read, 5 Families, at 4.31% — the highest badge we have seen on Duel by a clear margin. Even after rakeback its net cost is 2.16% of turnover, against 1.50% for Iron Bank at the other end of the table.
One title says nothing about the studio's other games on Duel; it says a fair amount about that title.

Method
How the Studio Data Was Collected
A studio is on this page because at least one of its games was opened on Duel and its page showed the studio name, the category and a badge. The lobby pass on 26 June 2026 read maker and badge for the titles named above; the catalog pass on 29 June recorded 32 of them individually; the wager tests on 17 July played eleven under the rules on the methodology page. Provider counts from casino reviews were not used: they count different things at different dates, and a maker that cannot be seen on Duel is not listed.
FAQ
Frequently Asked Questions
Which slot studios are on Duel?
Nine that we have confirmed on the live pages: Pragmatic Play, Hacksaw Gaming, Relax Gaming, Play'n GO, Nolimit City, Backseat Gaming, Reel Kingdom, Peter & Sons and Red Tiger. The lobby carries more; these are the ones whose game pages we have read and dated.
Which studio has the lowest house edge on Duel?
Relax Gaming holds the single lowest badge — Iron Bank at 3.00% — but its titles range up to 4.00%. As a band, Pragmatic Play is the most consistent at 3.40%–3.86%; the cheapest tested game is Reel Kingdom's Big Bass Splash at 3.29%.
Which studios have games you actually played?
Four: Pragmatic Play (six games), Hacksaw Gaming (three), Nolimit City (one) and Reel Kingdom (one). All eleven accruals matched the badge to the cent; the table is on the rakeback guide.
Why do reviews give different provider counts for Duel?
They count different things — every supplier including live-dealer and table studios, or slot makers only — at different dates, and some keep studios that have since left the lobby. This page counts only studios whose game pages we have read on Duel.
Do all games from one studio have the same RTP?
No. Relax Gaming alone spans 3.00% to 4.00% on Duel, and most studios ship several RTP versions of each title. The badge on the specific game page is the only figure that applies.
Is a studio's feature-buy option the same on every game?
No. It is switched on per game and per version; Rich Wilde and the Tome of Madness has none on Duel although Play'n GO offers it elsewhere. The table records only what each game page showed.
Which studio is best?
There is no answer that holds for every player. The edge band is one factor and a small one; volatility, feature design and how you intend to play decide more. Pick the game, then read its badge.
