Topic: PrimeDice Is A Scam! (Read 4398 times)

Sending the client seed to the server does not allow the server to cheat its users. To get the result, Primedice uses a server seed, user determined client seed and a nonce. The results are hashed from the server and the results are sent back to the user. There is no practical way for users to not transfer their client seed to the server and still play the game. For it to work without sending the client seed, the server needs to send its unhashed server seed to the client. The client would need to then hash them and generate the result. Any attacker can also intercept the unhashed client seed in the process. This would then allow for users to cheat the casino.

The results cannot be changed without changing either the server seed, client seed or nonce. Hence, before anyone start gambling, they need to randomize the server seed and take note of the server hash and client seed. They can then verify their results later.

I may be a newbie to this forum but I am not new to Primedice or gambling in general. When gambling, the odds so not suggest that there is an equivalent number of rolls. Every roll is completely independent from the previous one and even the next one. Therefore, when you decide to gamble you should know that you are destined to lose to the gambling house.

Common sense of peoples now-a-days.
If a person losses some bitcoins on any gambling site like he betted small and won when he betted max he lost then the site is scam , if he keeps winning he don't care even he dont say a positive word about that site .funny

It is called variance lol.

Its normal in gambling world dude. You will have more losses than your winning if you gamble simply because only few people really got a tough win. Your not the only one who experience that kind of scenario. Most gambler experience that not just in one site but in different site actually.

We note this.  We see that our seed was sent to the server every time that we changed. If the server have my seed, know how fuck me. This is fair? Every people can check this opening terminal of browser, in network panel, and see requests. 

those are just sore loser.. why don't they ask those winner of few BTC at one go whether the site is rigged ?

If they going to practice selective hashing, they would make it only in big bets, so they would not give hint about that. You just got bad luck, tha happens.
 If you are paranoid, just change your hash before each significative bet, and you will be fine.

The OPs "test" is much too small in order for it to be statistically significant. There is a good chance that many people will try this and get similar results, however others will likely get opposite results.

PD has been shown to be fair. [/thread]

In Nevada, they are supposed to totally random, they do have a house percentage edge, which is pretty high. I have seen the gaming commission actually do tests on them. I don't know what they do in Europe, but in Nevada they have to answer the Nevada gaming commission.

prime dice has no reason to scam it will beat you via mathematics, if you want to gamble then gamble its a great site.

LOL OP

its normal everything is good i once seen 18 reds and heard that some guy got 25 its completly normal

i got in 10 bets on prcdice 5 under 1.5 LOL

everything is good!

Yeah, so my question was can slot machine return 110% like dice game can?

Nice one buddy!

Not really a scam imho.

Gambling should be seen as a form of entertainment, not a way to make quick money. It would just be a lot easier if people applied common sense, a casino would not function as a business if it did not profit - simple as that.

I don't even know if it makes sense to talk about the "house edge" when every result is deliberately manipulated.

The "house edge" is the percentage of the wagered amount that the house expects to keep, in the very long run.

You can't talk about "expectation" when everything is being manipulated.

With dice games, the house edge doesn't change - it's 1%, or whatever it is set to. Just-Dice's house edge was 1%, even though the actual profit was only 0.3%. If the game ran long enough, the actual profit would have got arbitrarily close to 1%.

Shortly before closing the site, I calculated that it would take something like 100 years for the actual profit to get over 0.99% if betting volume carried on as it had been and if results came in pretty much as expected. Of course, it would also have been possible for someone to turn up one day and lose 50k BTC in 5 minutes, putting the actual profit over 1% very quickly. Despite all that, the house edge was always 1%.

Edit: note that slot machines talk about their "RTP" (return to player) rather than their "edge". They return 93% of bets to the players. Not because of the law of large numbers, but because they make sure that's what happens.


I'm keeping my options open. I don't want to run them illegally, so would have to run them out of a different jurisdiction, and that seems like a hassle.

But are those slot machines made so they can't go like 10% house edge?
With dice games housedge can go temporarily to 10% or more.

Actually, it's quite different than the slot machines, at least in the UK.

Those things aren't random. They are programmed to make sure that they hit their target payout percentage.

(Provably fair) dice sites *aren't*. They rely on mathematics alone to make a profit.

Just-Dice had over a billion bets, and millions of BTC wagered, but its overall profit was only 0.3%, whereas the mathematical house edge was 1%. The site did three times worse than it "should" have. You'll never find a slot machine (in a UK pub) doing that. Their manufacturers realise "variance is a bitch" and so don't allow it to happen. In effect, they are "rigged".

When they say 1 percent house edge they say thats for the long run. I could play there for a week and loose 80 percent of the time, and you go play there and win 80 percent of the time.. Its like those slot machines in vegas that say similar things. One time I won 1k bucks, that means there will be over 1k in losses to players.. yes, variance is a bitch...

Gambling in itself is a scam, now stop gambling if you can't take a lose.

I don't think a 15 loss streak in 500-1000 rolls is realistic. Sort of goes against the point you're trying to make anyway.

Come on not this kind of argument again.
Losing a high win-chance bet or encountering a long losing streak do not indicate the site is scamming at all. It could very likely just because you are having bad luck.

I really didn't know it's scam or not, i just lost 0.01 but i enjoyed it.
it's a game.. if i am not win, then i lost. 

Nothing in this post proves anything other than that you were unlucky.

The Number is random based on hash calculation
every site you try, will got same result

So, PrimeDice is not a scam 

House edge can be seen by the multiplier and the win chance of the rolls. There isn't a way to change the house edge without the user seeing it. The user can determine the fairness of the game and the house edge individually. If the win multiplier is x2, the higher the house edge, the lower the amount of chance of you hitting it. The lower the house edge, the higher the win chance for x2. You may want to look through this:http://casinogambling.about.com/od/oddsandends/a/houseedge.htm

There is no way for the house to even manipulate the rolls if you change your seed very frequently. I doubt Stunna does that even if you don't change it. Varience always happen, you can have long lose streaks at time and long win streaks at times. I suggest you to looki through this http://en.wikipedia.org/wiki/Variance

Here you go


Now tell me if i am the owner of the site on front page i can say low house edge but i can put the real house edge to what ever i want! It will make me profit!

even i have tried this earlier ,  i betted under 90 with 0.0001 and i win a lot , when i do with 0.01 and 0.1 ( 9 rolls i done ) and i lost 7out of those , lolz how u say its probably fair , haha

It's not just PrimeDice. Just yesterday I bet 5 BTC at 90% on PRCDice and lost.

What are the odds of that? You're meant to win 90% of the time but that bet won 0% of the time.

Joking aside, the soon-to-be-released PrimeDice 3 changes the provably fair algorithm to use the same server seed until the player changes it. That makes it much easier to verify your rolls than the current system (which changes the server seed every roll, and also uses a daily secret which you can't see until the next day).

The current (PrimeDice 2) system does in theory allow the house to cheat by analysing your betting pattern, assuming you won't change your client seed, and feeding you a series of server seeds pre-designed to give you bad rolls (not that I think they are doing any of this). The new release removes that possibility.

I'd be on your side of that bet.  The OP is the real troll :-/ 
@tftiurn, I see that you like double spacing and everything, but you forgot to show us the proof! 

Obviously you are going to experience different streaks with different odds. If you roll 80, the settings with roll under 49.5% one wouldn't win. However, the one with 90% odds will win. 90% chance basically lowers your payouts while lifting your chance of winning. While 49.5% lowers your chance and increase your payout.

I'm willing to bet he put in like 0.1 and did under 90 a couple of times for 0.00005 and won, then did it a few times with 0.1 and lost once or twice and is now pissed.

Set the seed.

You clearly do not understand about the logic of gambling. Gambling is not about your win lose ratio. Obviously, you would have larger lose streaks in bigger runs. It isn't anything they can control. Varience always happens, no one can prevent this and this isn't what a casino owner can control. Do you know what's house edge? It is the multiplier of payouts, with 0 house edge, you can have 50% win chance and 2x payout. With 1% house edge, the chance is 49.5% and payout is 2x.
PS. I am not a troll or supporter of Primedice. You are making false accusations about a specific casino without any true evidence which points towards the casino owner manipulation of rolls. Try it in any other casino and see if you will get your desired result.

Variance is different rolls.

The streaks are changing with different types of bets, which = SCAM = Change of odd's per % win.

This is called variance.
You can check it is legit with hashes.

Don't pay attention to most of the trolls posting below, I know they will. Re read the message and try it for yourself.

ANYONE who even posts within 1 hour of posting, is obviously a troll, as they haven't tried the method out for themselves.

Im not saying you cannot profit, you may profit, but they are lying about odds, its not 1% house odds.

Go preroll or bet, bet Over 49.50, do this about 500-1000 times automated betting.

Realize, your biggest loss streak, will be 15+

Now, go bet Under 90.

Do not keep track of wins/loses, keep track of how many times your roll goes under 50.

You will see the biggest streak under 50, is around 5-7. NEVER WILL GO TOO HIGH.


Now, if you do not believe me go try it out.

If you still think it's a random roll...it's not. How can the streak's change? UNLESS the site was rigged, to change the odd's according to the win percentage.


Another theory I have which isn't quite strong, try betting .000005's on under 90. constantly. Watch how you will win so much.

Now try betting .1's on under 90. Watch how you will lose a lot. 90+ happens way more than 90% of the time.

What 90% means, in the long run, 100 rolls, 90 you will win. 10 you will lose. But notice if you preroll even 40 90's in 200 rolls. Raise your bets, watch how much you will lose.


I would advise to stay away.
