Duel7 games
Around 3,000+ titles in three tiers that behave very differently once rakeback is applied. The important distinction is not genre — it is who wrote the game.

AFTER RAKEBACK
Three tiers, not three genres
Most casinos organise a lobby by category — slots, live, table, game shows — because that is how players browse. It is a useless way to understand what a game costs you. The distinction that actually determines your return is who built the game and therefore who sets its margin.
In-house Originals are configured by Duel, and Duel has set their edge to zero. Third-party slots are configured by the studio that made them, and Duel cannot change the base return — only add rakeback on top. Live tables come from Evolution with mathematically fixed edges determined by the rules of the game itself, with rakeback again layered over.
That structure explains the business. The Originals cost Duel money and exist to bring people in. The slots and live tables are where the operator actually earns, and rakeback is the discount that makes them competitive rather than the loss leader.
The Originals
| Game | RTP | How it works |
|---|---|---|
| Crash | 100.00% | Multiplier rises until it busts. Cash out first. |
| Dice | 100.00% | Roll under or over a threshold you set yourself. |
| Plinko | 100.00% | Ball falls through pegs into a multiplier slot. |
| Mines | 100.00% | Reveal tiles, avoid mines, cash out when you like. |
| Keno | 100.00% | Pick numbers, match the draw. |
Five games, all at 100%, all provably fair. This is not a promotional rate with an expiry, a daily allowance capped at a small figure, or something you unlock at a loyalty tier. It is the standing configuration.
Every round is reproducible. A server seed is hashed and published before you play, you supply a client seed, and a nonce increments with each bet. Feeding those through SHA-256 gives the outcome, which means you can verify that the result was fixed before you placed the bet rather than chosen afterwards. Crash goes further and pulls entropy from the drand beacon, a public randomness source run independently of the casino, so neither side can influence a round even in principle.
The honest caveat: zero house edge does not mean you cannot lose. Variance is completely untouched. A run of losses on a game with no edge is entirely ordinary and says nothing about fairness. What is removed is the systematic drain — over a long enough run the expected return is exactly what you staked, which is a proposition no traditional casino offers on anything at all.
Full mechanics, payout tables and verification walkthroughs are on the Crash, Dice, Plinko and Mines pages.
Slots
Roughly two and a half thousand titles from Pragmatic Play, Hacksaw Gaming, Nolimit City, Push Gaming, Relax Gaming and the rest of the standard roster. Base return is set by the studio and typically lands between 94% and 97%, and 50% rakeback applies on top — a game shipped at 96.43% behaves like 98.22% in practice.
One detail worth knowing that almost nobody mentions: studios ship the same game at several different RTP configurations, and the operator chooses which one to license. The identical title with identical artwork can run at 96.5% at one casino and 94.2% at another. Duel runs standard configurations rather than reduced ones. You can verify this yourself in the info panel inside any individual game, and it is worth doing at any casino before you settle in.
Volatility will affect your evening far more than the RTP differences between studios, which after rakeback amount to about two-tenths of a percentage point across the whole range. Nolimit City and Hacksaw sit at the extreme high-variance end as a matter of house style — long dry runs punctuated by large hits. Match the volatility to your bankroll rather than to your mood, and the slots page has provider-level detail.
The gap in the catalogue is progressive jackpots. There is no network here paying a seven-figure hit, and no amount of rakeback substitutes for a prize that does not exist. If that is what you play for, this catalogue will disappoint you and the disappointment is structural rather than fixable.
Live casino
Evolution supplies roulette, baccarat, the game shows and most of the blackjack, streamed from their studios with real dealers and real equipment.
The standout is the house-run Duel Blackjack Beta table. Correct basic strategy already brings a shoe close to 99.46%, and returning 60% of the remaining edge produces an effective 99.78%. That is the highest live table return we have found anywhere online, and it is the only game on the site where your own decisions move the number — in both directions. Play by instinct instead of strategy and the base edge widens faster than rakeback can close it. Rules, limits and the full calculation are on the blackjack page.
Roulette carries the single biggest avoidable mistake available at this casino. Two wheels sit side by side and look nearly identical; one has a single zero at 2.70% edge, the other has two at 5.26%. After rakeback that is 98.65% against 97.37%. Nothing in the interface warns you, and choosing the wrong one costs more than every other decision on this page combined.
Game shows — Crazy Time, Monopoly Live, Lightning Roulette — sit around 96% base, roughly 98% after rakeback. That is respectable for a category that usually carries much wider margins, and they remain the most expensive hour on the site outside the double-zero wheel. They are priced as entertainment and should be treated that way.
The same studio hosts the celebrity sessions that pushed the casino into general awareness, Mike Tyson dealing a shoe among them. Those are collected on the videos page.
The studios, and why they feel different
Slot providers have house styles the way film studios do, and after rakeback the RTP differences between them are small enough that style matters more than return.
Nolimit City builds punishing, mechanically dense games with extreme variance and dark art direction. Long dry stretches, then occasionally something enormous. Not a catalogue for a small bankroll.
Hacksaw Gaming is similar in variance but lighter in tone, with simpler mechanics and heavier use of bonus-buy features where those are available.
Pragmatic Play is the broadest of the group and spreads across the whole volatility range, which makes it the safest place to start if you do not yet know what you like.
Push Gaming and Relax Gaming sit closer to the middle — moderate variance, cleaner mechanics, sessions that last longer on the same deposit.
None of this changes the maths meaningfully. All of it changes whether a two-hundred-dollar bankroll gives you twenty minutes or two hours, which for most players is the question that actually matters.
Bonus buys and why they are worse than they look
Several titles offer to sell you direct entry to the bonus round for a multiple of your stake — typically eighty to a hundred times. It feels like buying the good part and skipping the wait.
The arithmetic rarely supports it. Bonus-buy RTP is usually configured slightly lower than the base game, and even where it is identical, spending a hundred times your stake in one action compresses an enormous amount of variance into a single moment. A bankroll that would survive two hundred spins survives two buys.
Rakeback does apply to the purchase, since it is charged on turnover like any other wager, so a hundred-dollar buy returns roughly $1.79. That is real but it does not offset what buying does to your session length.
What a session actually costs
Worth grounding the percentages in something concrete. At two dollars a spin and roughly six hundred spins an hour, an hour of slots turns over $1,200. At 3.57% base edge the expected cost of that hour is about $43. Rakeback returns roughly $21 of it, so the real expected cost is closer to $22 an hour.
Compare that with an hour on the Originals, where the expected cost is zero and only variance remains. Or with an hour on the double-zero wheel, where the same turnover carries an expected cost near $63 before rakeback and $32 after — half again more expensive than slots for no additional entertainment.
These are expectations across many hours, not predictions for tonight. But they are the honest way to think about what an evening costs, and they are considerably more useful than a return-to-player percentage on its own.
What the lobby does not tell you
Two things worth checking yourself rather than taking from any review, including this one.
The info panel inside each individual slot carries that title\'s configured RTP at this operator. If it disagrees with anything on our RTP table, the info panel is right and we are wrong. Studios revise configurations and operators change licences, so a table written in one month can be stale in the next.
The live table limits are shown before you sit down and vary considerably between tables that otherwise look identical. A blackjack table with a two-dollar minimum and one with a fifty-dollar minimum run the same rules and return the same percentage; which one suits your bankroll is not a small detail.
Choosing what to play
Three readings, depending on what you actually want from an evening.
Longest session per dollar: the Originals. Zero edge means the expected drain is zero, and low-stake Dice or Plinko will keep a small bankroll alive longer than anything else available.
Best return with a skill component: Duel Blackjack Beta, provided you learn basic strategy first. The 99.78% figure assumes it and is fiction without it.
Entertainment first: slots and game shows, with volatility matched to bankroll rather than to ambition. Rakeback accrues on every spin regardless of outcome, which is the one thing that behaves the same whether the night goes well or badly.
Category-by-category figures are on the RTP table, and the rakeback rates behind them are on the rakeback page.
