Duel.com -- The first casino with 0% house edge games

[Dollartree]

0% house edge is a very ambitious title to claim. I just checked Duel's original games and all of them are with 100% RTP except the game called Beef. Why is that? I'm really curious. Do you guys have a beef with that game's RTP? I don't see RTP badge on Slots and Live Casino, so I assume that Slots have their traditional RTP and live casinos share the same RTP everywhere.
By the way, is it possible to partner with a live casino supplier and have a dedicated table where you'll offer Roulette or Blackjack with 0% house edge? That would be really very cool.

I think the 0% house edge is only applicable to their original games and yes the table games, live casinos and slots have their default RTP percentage. The Beef has 99.2% RTP, it's their new game and I'm not really sure what's the reason why it's not 100% compared to their other games. Regarding the roulette it's not their original game and I don't think the provider would let them have 100% RTP since those providers were getting paid monthly (correct me if I'm wrong) and if the Duel team wants to have it 100% RTP, what they can do is offer cashback or bonuses.

The reason Beef has a small edge is that Duel wanted a house game that earned leaderboard points and gave referral rewards.  The 0% edge games don't award leaderboard points due to obvious issues with point farming.

In regard to live games and slots, Duel effectively cut the house edge in half for all of these games.  50% of the house edge is given back to the player in instant rakeback.

Most people don't realize just how much rakeback they get on Duel, so my advice is to let it build up and not claim 0.50 after each slot you play.  Claiming $100 at the end of a good session really provides some clarity to that.

Maybe you will like their Castle Roulette? it's also a live game with zero percent house edge, only it's from Duel.

Honestly, I find this particular game hilarious purely for how it is setup LMAO. Because we're usually used to formal setups like people all dressed up, and this is just like hanging out with the homies. I would say this one is a nice comical approach lol.

I did see this before on my X.com feed, and initially thought it was just part of the skit. LOL.

It looks to be a very creative game from Duel.com, and this visual design of the game can help its finding more users who are ready to play this game at Duel.com

However I really wonder that how users can verify and know that a game is truly zero percent house edge or not. As we can not trust the information given by any casino company. Similarly to provably fairness of a game, that needs to be verify with Provably Fair Verifier tools, so I have the same concern with a game's house edge.

Do you know how to verify this information, and if you know it, could you share that method please.

This game is very easy to calculate the house edge.  There are 48 sections to the wheel.   There is (1)48x, (2)24x, (3)16x, (6)8x, (12)4x, and (24)2x.  You can see there is no edge in the game because any multiplier you bet has true odds of winning.

With your shitty reading comprehension skills, I'm not surprised you say things like that

Sorry, but it would have been better if you have took the time to explain to him the difference between a provably fair game and a game with zero house edge.
Whether we like it or not, many gamblers do not even know what provably fair means. I’m also pretty sure most of gamblers don’t know how to verify the results by themselves.
However, I’m pretty sure he knows that being provably fair doesn’t mean having zero house edge.

[Free Market Capitalist]

Sorry, but it would have been better if you have took the time to explain to him the difference between a provably fair game and a game with zero house edge.

What would have been better is that instead of coming here to try to lecture me on what I should or shouldn't do, you would have taken the time to explain to him yourself what you say I have to explain to him. Wasting time explaining something obvious to someone who doesn't even reach a 0.3 merit to activity ratio isn't my thing.

I don't think it's a coincidence that those of you who come to this thread to raise doubts about whether Duel is provably fair or not, or to try to lecture others, are people who are promoting other casinos.

If anyone wants to cast doubt on whether Duel is provably fair, all they have to do is prove it. If they don't know how to check, there's this thing called the internet, search engines, and another thing called AI. I'm not a kindergarten teacher who has to explain obvious things. And the same goes for 0% HE. If anyone wants to cast doubt on whether the games that Duel promotes as 0% HE actually are not, what they have to do is provide evidence.

Sometimes if it is not a user promoting another casino, it will be a newbie account that will keep spamming the Ann thread to raise doubts and accusations. This is something that many good casinos here in the forum face.

If anyone wants to cast doubt on whether Duel is provably fair, all they have to do is prove it.

In the legal space, he who alleges must prove.

It is not okay to accuse a casino. If you have an accusation against a casino, you have to provide concrete proof to have a case.

[TryNinja]

Talking about provably fair, you can always verify the game yourself: https://duel.com/fairness/verify

Even better, if you check your transactions (https://duel.com/transactions/bets-casino), you can click on any bet and there is a "verify" bet option that does everything for you.

They even provide a javascript code so you can run the check on your own:

[DuelScam]

Between February 6th and 15th, I placed 26 bets on Duel, ranging from $5 to $70, mostly on football (LaLiga, Serie A/B, Premier League) and a bit of basketball. I made a deposit of $225, won a few bets, and withdrew $300. After that, I continued betting for a couple more days, and my balance grew to $883. At that moment, I was unable to withdraw the money, so I wrote to the chat, and support replied that I needed to pass KYC. I fully completed the 3-level verification, including ID and proof of address. My verification status is "Completed." After that, support replied that I needed to wait 24-48 hours. During this "review," I tried to find out the reason, but no one ever responded to me. In the end, on the third day, they told me that they had completely voided my bets and my balance became negative $76. This is just ridiculous. Support cited "multi-accounting" as the reason, even though this is the only account I have. Moreover, I fully completed verification, and I am absolutely sure there is no other account using my data. After this, I spent a couple of hours talking on their official Discord channel, but I achieved nothing there. They didn't provide me with a single piece of evidence of my violation. Furthermore, the admins responded to all my logical questions so stupidly, as if their IQ is below room temperature.

So, to summarize:

1. I successfully passed 3-level verification.
2. My bets were between $5 and $70, which is literally 1-2% of the maximum bet on a match. What reason would I have to create multiple accounts "to increase limits"? In that case, I could have been betting $50-$700 from a single account.
3. I was placing bets for 10 days; why didn't you block me earlier, then?
4. You have no proof whatsoever. (And you won't find any because I didn't violate anything.)
5. On Discord, when I tried to resolve the issue, Duel admins openly insulted me, even though I remained polite even after this scam. This just shows the lack of education among the entire casino management.
6. One of the admins on Discord wrote that "there are sports syndicates that abuse casinos, but they use different IPs, and it's impossible to prove a connection between accounts." I'm writing again: I am not an abuser and am not connected to anyone. But if it's impossible to prove a connection even between such syndicates, then how does their system work? Why was I, an ordinary user, brazenly scammed in that case? It seems they block winning accounts without any proper review.
7. Yesterday I saw similar cases from people on this forum. These are likely widespread occurrences. Be careful and don't fall for their advertising like I did.

Oh, and the funniest part. During this whole time, all the admins, including the owner with the nickname "Monarch," were sitting in the Discord channel. Instead of any kind of help, they were discussing some easy girls and making stupid jokes, as if I had wandered into a channel full of kids. Just think about it—can you trust your money to such idiots? Proof:

..

A multiple account violation can’t be justify because you can’t provide any evidence that you don’t own those account connected to you while casino have.

I doubt they will just invented those connection out of nowhere just to scam 883$ while they are spending more than that with their signature campaign here.

Challenge them on Askgamblers platform which they can provide their evidence.

Hey man, I work support at Duel and took a look into this.  Your account was limited and these bets were voided because its VERY CLEAR that you were using alt accounts to evade limits.  You were given MULTIPLE warnings to stop doing that, and if you continued, your bets would be voided.   You ignored those warnings, and the bets were voided.

You stated in the discord channel "I think it's logical that if I've passed verification and my data wasn't in the system before, then I'm no longer a multi-account user".  We don't get into exactly how we track people multi-accounting, but KYC is NOT the only metric.

Monarch has been running casinos for almost 10 years now.  He's not going to scam a random player for $800.. its just not going to happen.  During those 10 years, the people working for him have gotten very good at detecting things like this, and something like voiding bets doesn't happen unless those people are 100% sure you are breaking the rules.

How many cases like this do we see? And I'm not referring to this casino. A lot. But then it turns out that we forum members have never had a problem with that, and those of us who know how a casino works know that it's not going to confiscate $1K to scam people. For a casino to operate, it just has to make sure there's enough traffic. The HE does the rest. $1K is peanunts.

I'm not saying that there hasn't been a mistake in this case, because sometimes it happens and we see the casino refunding the money to the user but there's no way they'd confiscate that amount without having some indication that the user broke the rules. And I say this about this casino as well as many others that advertise on the forum and we see similar accusations.

Well, I was going to post and see a new message has been posted.

This is the curse of this forum,,, majority of posters are posting, not reading, not responding. And even worse, majority of posters who post in Gambling are not even gamblers. I would just be selective about who to respond to,,, you will see after a while who is worth discussing with.

They do not know what provably fair is, they do not understand that actual RTP and house edge is not the same thing (0% house edge is not 100% actual RTP), I see it even in chat rooms people coming in to complain about dice like 'I lost 15 in a row, scam',,, we live in a world where people are just babied in knowledge, everyone else must do their thinking for them.

This is so true man.  Glad to see the intelligence here is generally much higher than other places I've been.  Users reach out every day screaming that it can't be 0% edge because they lost 10 blackjack hands in row.

I find myself saying "Just because it's 0% edge doesn't guarantee that you'll win" multiple times per day, but educating angry gamblers isn't an easy task.  It's easier to yell "scam" than learn how it actually works.

[memehunter]

actual RTP and house edge is not the same thing

Really! What do you mean by that? is the word 'actual' is the prime differentiating factor here? My understanding is also that both are essentially same in large enough sample sizes. I am eager to know how are you creating this difference.

0% house edge is not 100% actual RTP

I believe that 0% = 100% RTP in large enough sample sizes.

[khaled0111]

No need to take things personally.
I wasn’t trying to lecture you or anyone else about what to do and I’m in no position to do so. Also, I don’t see where in my reply I raised any doubts or questioned the legitimacy of Duel’s provably fair system. So I don’t understand the reason behind all this hostility!
In any case, I can guarantee you that whatever I write in any casino’s ann thread has nothing to do with (not influenced by) the casino I’m wearing it’s signature.

Really! What do you mean by that? is the word 'actual' is the prime differentiating factor here? My understanding is also that both are essentially same in large enough sample sizes. I am eager to know how are you creating this difference.

There might be a difference between the actual RTP and the theoretical RTP. This difference depends on the gambler’s luck and mainly on how many bets he has placed. You are right, the more bets he places, the more the actual RTP leans toward the theoretical RTP.

[mikel_012]

It's just business as usual with these accusations.

We need to remember that the bad guys are always more noisy than the good guys. If someone cheats the casino they will always come to the ANN topic to talk bad and try to get the money back. Nothing new here

There is no doubt that Duel is provably fair. If you visit the website you can see they have a easy tool to verify every bet

If someone is doubting that, they probably do not know how any of this works or just want to FUD the competition without having any proof: https://duel.com/fairness

0% house edge is not 100% actual RTP

I believe that 0% = 100% RTP in large enough sample sizes.

He is wrong. RTP and HE are two sides of the same coin. It doesn't matter the sample size.

I wasn’t trying to lecture you...

False.

False as well. Unless you want to play on words here. If the RTP is 98%, it doesn't matter if you get 300% or -50% in the short term. RTP is a mathematical concept, and what you call short-term RTP results have nothing to do with the mathematical concept.

0% house edge is not 100% actual RTP

I believe that 0% = 100% RTP in large enough sample sizes.

He is wrong. RTP and HE are two sides of the same coin. It doesn't matter the sample size.

In any probabilistic environment, sample size does matter. In mathematics, it is about certainty and rigorous proofs. Mathematics are deterministic, law of nature.

Statistics are probabilistic and empirical and you actually often times approximate results via sample size. You have a whole different toolset to evaluate outcomes (CI, RA, mean, median, SD...)

So sample size does matter individually, but the question asked here (I guess) is whether the collective RTP is 100% (in a large sample size, which I assume is approximately given if Duel has a lot of users). If they have a ton of players, Duel should hand as much money out as they are cashing in from players over time.
 
I can't say for sure, but maybe the word "actual" that @leea-1334 used, was to imply that for an individual, the 100% RTP rate is rather irrelevant unless that individual plays enormous volumes distributed among a very large number of events (dice rolls, slot rounds etc.).

There might be a difference between the actual RTP and the theoretical RTP. This difference depends on the gambler’s luck and mainly on how many bets he has placed. You are right, the more bets he places, the more the actual RTP leans toward the theoretical RTP.

What @khaled0111 labels as "short-term RTP" is most likely referring to a small sample size because sample size clearly matters. The larger the sample size, the closer the relationship between average payout and average wager, aka 100% RTP convergence.

In a probabilistic environment, which I think a casino is (it is not mathematical), a 100% RTP essentially means a redistribution of funds among players following a stochastic process.

Nice wall of text but I don't know why you are quoting me because that has nothing to do with what I am saying. RTP and HE are two ways of expressing the same. They are mathematically interchangeable; if a game has a HE of 2%, it is because the RTP is 98%, and vice versa. So leea-1334 si simply wrong.

What @khaled0111 labels as "short-term RTP" is most likely referring to a small sample size because sample size clearly matters.

So, what @khaled0111 wrongly labels as "short-term RTP" would be more accurately described as short-term results, not "short-term RTP".

You are frequently losing yourself in semantics, but it is ok. At least there is some hope that you do understand the concept of sample size in statistics, not mathematics:

...more accurately described as short-term results

whereas your "short-term" here undoubtedly refers to a low number of events (aka small sample size).

It doesn't matter the sample size.
