they're all provably fair, but their house edge varies from 0.5% to 1.9%. The house always wins anyway.

House always winning and being provably fair doesn't refer to the same thing. In the long run the house always wins even if they are provably fair, because of the house edge.

It is only provably fair if you take the time to verify your games. You could read my detailed article at: http://dicesites.com/provably-fair for a better understanding of how provably fair works.

No established bitcoin casino can go on for long without a strong provably fair system. Just search around for well known casinso, there's dozens.

And lucky.bit have about 1% house edge

If you need dice site with low house edge, then try SafeDice
They only have 0.5% House edge

Correct me if im wrong but I think luckyb.ithas no house edge coz its not a dice site, its a plinko..

Every casino game has a house edge.
It doesn't matter which type of game it is.
Roulette wheel has a house edge. When you bet on red and win, you double your bet.
But when the 0 comes out, the house collects all the bets on red and black. :D That's the catch.

luckyb.it house edge is somewhere between 1% and 2% I believe.

You didn't understand that quote. It doesn't mean the game is rigged and they are cheating, but that you may have a winning streak but it will eventually be followed by a losing streak.
The house always wins in the end :)

Looking at the number of gambling sites, all sites have been switching to a provably fair model of gambling.
So most of them are. The big examples are Primedice/Coinroyale/Cloudbet(asits live)

About Provably fair conception. I have my explanation, but this one is better than mine, so I just show you this passage.

http://dicesites.com/provably-fair

What is "provably fair"?
Players always fear to be cheated on an online casino. This is understandable because it is technically very easy for an online casino to just make you lose. In the Bitcoin gambling community we have a solution for this called "provably fair". Provably fair is a tool that enables you (the player) to verify each roll result and make sure you are not being cheated!

The easy way is to just use our provably fair verifiers, fill in the information the website is providing you and check the roll results.

Primedice has a house edge of 1%. When PD3 was released, it came with a jackpot feature making the house edge 0.91%. But the feature has been removed now.

LB has a house edge of roughly 1.66% - 1.76%, depending on which line you are playing.

AFAIK there are at least 2 games with 0% house edge, the PvP on Primedice and the PvP raffle game on Peerbet. The downside is that there are not many players and it is hard for you to find a good match.

A dice with 0% house edge would still make profit so i dont know why no one made it, it would atract a lot of players

I don't quite get it. By definition, "0% house edge" means the game has a expected value of zero to both the players and the house.
So how would a 0% house edge game bring profit to the house?  ???

It doesn't in itself.

But the house hopes players will play other house games that do have a house edge.

It's a marketing strategy.

Not really?? With a 0% house edge casinos would still win, why? Easy at the moment you start using a strategy, it doesnt matter you name it, martingale you would still lose using martingale, yes the odds are a bit better per bet now but you will still see 20 lose streaks or more, the 0 house edge only affects players if you bet static, you bet 10k satoshis every bet, yes in the long term you would have a 0 profit but no one is gonna do that, right? So as i said before casinos would still win

Well it looks like you are assuming people will keep on playing until they are broke. :P
With that assumption, I guess you are right. A player need to have extremely good luck to wipe out the house bankroll before losing all his money, when the house has hundreds or thousands times more bitcoin.

Op, as you now probably know gambling is not that easy you will probably lose more than you win. You will lose no matter what, it does not matter if game is rigged or it is "provably fair" I got the impression that you are looking for a online bitcoin casino which is better than most because it will allow you to win more. There is no such place. So just pick your favourite casino and start playing.

Provably fair simply means -- "if the casino cheats you, you can detect it". It doesn't mean you can stop them cheating you (you can't) and doesn't mean you expect to make money (you don't). It just means that if the casino is cheating you, it's detectable.

ok, thank you all,
but how about 999dice? its recommended for gambling?

No, definitely not. They lie about being provably fair, with a backdoor scheme. If they cheat you, you can't know for sure. Hence it being not provably fair. This place is scum anyway, you should avoid it. They also claim to operate on a 0.05% margin, while allowing 40 BTC wins. lolz

I thought there were casinos with 0% house edge around here, correct me if im wrong

There are. Some PvP games allow no edge (since they're not exposed to any risk). Money Pot allows you to play with a 0% house edge (by instantly cashing out) at the expense of being bait to bonus snatchers. DirectDice spams every thread with claims of 0% for frequent betters. I haven't looked into it though, as it sounds like some tard/scammy scheme.

Not really?? With a 0% house edge casinos would still win

That's incorrect, as is your reasoning. You can write a simulation if you don't believe it. But even if the vast-majority of people will bust with a 0% house edge, the ones that don't will bust the house. A casino couldn't safely offer a 0 house edge game for a single satoshi if it could be played an infinite amount of times.





If i write a simulation using martingale i will eventually bust, and that would happen with any other strategy, why dont you try it yourself, your reasoning is incorrect not mine, the ones that dont will bust the house? People are greedy, for example the guy who won 7k btc on just-dice and ended up loosing, people its always greedy and thats why a 0% house edge casino would still win

Ok, let's do it -- a simple simulation of a greedy player who never stops gambling (unless he busts):


Code:
var startingBankroll = 100;
var bet = 1;


while(true) {
var bankroll = startingBankroll;

for (var i = 1; bankroll > 0; ++i) {

bankroll += Math.random() < 0.5 ? bet : -bet;

if (i % 100000000 === 0)
console.log('Player has made', i , 'bets at a profit of:', bankroll-startingBankroll, ' BTC');
}
console.log('PLAYER BUST!');
}

Now run that, and watch as the vast majority of players will bust. But occasionally you'll get to a real gem like this guy:

You really think the casino can handle billions of more bets, hoping it can make its hundreds of thousands of bitcoins back? And do you honestly think a casino would be willing to expose itself to unbounded liability for 0 expected profit?! It doesn't work, never has, never will.

But perhaps, what we'll see is bet-match-making where 0% house edge is actually feasible. That way players can play with 0-edge, and casinos aren't the counter-party

I dont understand that at all, what is that player using? Martingale? And how is he making 4 bilion bets?

He is able to make that many bets -- because he hasn't yet busted. In my simulation, the player never quits until he's busted (just like you said, about a player being greedy). So even though he's up hundreds of thousands of bitcoins, he caries on. Which just shows how ridiculous using the "greed" nonsense is. With no house edge, a player being greedy doesn't help the casino -- just increases its chance of the casino busting (all for making 0 expected return. a silly value proposition)

What strategy is he using ???

Im sorry to tell you but your simulation is wrong or i just didnt understand how was the player betting

I don't think there are such casinos around. the best suggestions would be primedice, coinroyale.

There are fair casino's just look at any that have been out the longest and i am sure if there was a problem then there would be multiple complaints in any amount of time before i started my sig campaign i played bitdice and never had a problem in well over 5 months the site has been going over a year so i recommend them for that plus a decent owner who will not do a runnerr.

I would give Dadice a go they are spending a good amount on their campaign and that is a good sign to me that they mean business and they are not about to release a unfair dice site that will not last a week before complaints ya know, has graphics and is a fun experience highly recommended and not just because i am wearing their sig lol

Most sites these days use provably fair.

However you need to keep in mind that since the client seed doesn't usually change, they can still cheat you assuming you never change your seed.

If i write a simulation using martingale i will eventually bust, and that would happen with any other strategy, why dont you try it yourself, your reasoning is incorrect not mine, the ones that dont will bust the house? People are greedy, for example the guy who won 7k btc on just-dice and ended up loosing, people its always greedy and thats why a 0% house edge casino would still win

Ok, let's do it -- a simple simulation of a greedy player who never stops gambling (unless he busts):


Code:
var startingBankroll = 100;
var bet = 1;


while(true) {
var bankroll = startingBankroll;

for (var i = 1; bankroll > 0; ++i) {

bankroll += Math.random() < 0.5 ? bet : -bet;

if (i % 100000000 === 0)
console.log('Player has made', i , 'bets at a profit of:', bankroll-startingBankroll, ' BTC');
}
console.log('PLAYER BUST!');
}

Now run that, and watch as the vast majority of players will bust. But occasionally you'll get to a real gem like this guy:

I dont understand that at all, what is that player using? Martingale? And how is he making 4 bilion bets?

I'm no coder, but the code seems straightforward to follow... the player starts with 100 and bets 1 each go at 50%.

This player has not yet busted and is up 338k after 46 billion bets.

The point is espringe is correct in his analysis and his explanation.  

People have it ingrained in their heads that 'the house always wins'. This is due to a house edge, even if its 0.01%. No casino could survive offering only 0% games.

If he is betting 1 btc each time, the expected profit in the long term is 0, how is he able to make 200.000 bitcoins? How is he able to win 200.000 more than loosing when the chances are 50/50? Makes no sense

You can browse a list of nearly all Bitcoin casinos on TheBitcoinStrip.com (https://thebitcoinstrip.com/) and filter by "provably fair" up the top right. :)

He'd only need to double his coins 17.6 times to earn more than 200K coins starting from 1.  The probability of that happening is 0.5^17.6 is 1/200000.  Which means 1 out of 200000 people will encounter this.  Doesn't seem too far fetched to me.

What do you mean double his coins? Double 1 btc 17.6 times? Like 1,2,4,8,16,32,64 ... ? Because if thats what you saying it would be impossible since casinos have a max bet so i still dont see how that is possible unless you explain yourself better

Looks like i didn't look at the simulation code.  The code basically does a bet of 1 for each round (thus satisfying any concerns about max bet limits).  And thus, the bettor was able to get a profit of 200k with only bets of 1.  This might seem impossible, but it clearly isn't.   I'm sure someone with better math skills that I have can figure out the probability of this happening, and it clearly is > 0.

The probability of this happening is much much smaller than 1/200000, but still larger than 0.

TLDR Minuscule probability doesn't mean impossible.

It is far fetched if you consider the total number of total possibilities that exist and he would have to hit that streak on the first bet.

it's far fetched to believe YOU will be the 1 out of 200k people to win in this scenario.  It isn't far fetched to believe that there WILL be 1 out of 200k people to do it.  as this is what the probabilities tell us.  (notice that in real life results, you'll have some factor of variance along with this mean)

It's impossible for one person on one try.  But take a LOT of people trying this, and maybe one person will do it.  Thats the point.  That one person is not an impossibility, and if you are a casino operator, you will not want that possibility to happen.

Seriously, are you trolling or what???

He has bet 46000000000... that's BILLION... times. He is only up 338000.

Calc 338k / 46 billion.  = 0.000007%.

 Now ask the question again, does it seem possible someone could be up only 7 after a massive 100000 bets. YES, seems easily possible to me... I seriously dont get why you think this would be so impossible.

they're all provably fair, but their house edge varies from 0.5% to 1.9%. The house always wins anyway.

which one the most little house edge?
house edge take effect on our game?

Primedice have 0.9% house edge
And lucky.bit have about 1% house edge

If you need dice site with low house edge, then try SafeDice
They only have 0.5% House edge

i've played in luckybit, it was funny
primedice yeah its very famous around here.
oh really just 0.5%? but the site is legit? imean safedice legit?

First of all it is impossible for someone to make a billion bets, even a million its extremely hard so thats that, now if he were to make 1 million bets he would win 7 btc with a 0.000007% chance so yeah as you can see unless he finds a way to make billions of bets the 0% house edge casino would still win
