Okay, we have a Provably Fair implementation that will be made more obvious soon enough on the next patch, let me know if this works for you guys in the short run:

Dice
Slots
Plinko

Presently these links are only found in our FAQ specific to any game.

Warning: There is currently a bug with how the "user seed (nonced)" is displayed. It is suppose to have a "-" between the nonce and the user seed, so if you're "user seed (nonced)" is something like: "WBteQwqBn27YyDDVX1Q2p13mi413FB42", it's actually supposed to be "WBteQwqBn27YyDDVX1Q2p13mi413FB-42". This will be fixed with the next update soon.


My favorite game has been red slots for this same reason. If I'm going to gamble, I want something to happen, so I personally want the variance increased to the absolute maximum But different strokes for different folks. I'm actually happy to hear your story because it sounds like we developed a good range of outcomes for different types of people that make each of you happy.

My wife enjoys the slots as well, she has been playing on the blue one for a while and doesn't like the green and red ones, she likes to win even if small and just continue gambling instead of gambling and losing for a long time hoping you can hit big once.

I am exactly the contrary, I hate gambling for hours and have exactly zero to show for it, I may break even and that's fine but I just dislike the notion that I just spent hours and made zero, either Imma lose all my money in the end or Imma profit a ton with a big jackpot or some big win, that is when I feel like I am actually gambling. Otherwise whats the point if at the end I lost just couple thousand satoshi or won couple thousand satoshi, it is not never happened and doesn't matter, it is the big wins that matters to me.

while I do agree that manual processing of big amounts is a must ( to check if there wasn't anything shady going on  )
generally , manual payouts is what makes gamblers reconsider playing at a casino
nothing could be worse when you que your coins to get paid and they  do not arrive to your wallet
makes all kind of scenarios run through your head , you start to ask people in chat , worry etc.
and doublespending is not a thing anymore , there are no casinos that I know that accept instant deposits and frankly , there is no reason to do it
after your deposit gets one confirmation , you cannot doublespend , not possible

What you're describing is called double spending.
It can happen if a blockchain forks/splits into two chains for a little time before one of the two chains becomes invalid, usually because an entity takes over 50% of the consensus of the network.

This is something every unlikely to happen with Bitcoin.

Also if a transaction is canceled because it was sent with too low fees, then it has never been confirmed and there's no reason any company would credit you the amount of an unconfirmed transaction.

Of course manual processing is needed especially for big withdrawals. I actually hardly make any small withdrawals (never less than $50) so I always make my withdrawals carefully and on a significant amount,,, and it the site's hot wallet is big enough I get it instant (Talking about yolodice and bitvest for example).

If not, admin just has to do it manually for big amounts. VERY normal.

Just like nc50lc said. It's pretty simple. Here you can find explanation (written in a way that average user can get it) together with example.

And few more links from BTT:
https://bitcointalksearch.org/topic/provably-fair-how-fair-provable-is-it-5184988
https://bitcointalksearch.org/topic/a-guide-to-how-provably-fair-works-161236

It's pretty simple actually.
You (the site) provides the next bet's Server SEED hash in advance, an editable client SEED which was automatically generated by the client (+nounce depending on the algorithm) and the algorithm itself; eg. a link somewhere in the betting area.
The server seed was hashed because the player can cheat the system by changing his client seed if the actual server seed is displayed, and for verification if the same seed was used for that bet.
Then each bet's server seed should be displayed in the "bet lookup" info (for verification / to reproduce the bet result)...

...It's good to hear that the provably fair system was already on testing stage.
But AFAIK, I thought I've already seen the site stating "Provably Fair" months ago, maybe it's from a different site

I still think that confirmation based ones are easier to deal with. It means the gambler would have to wait for confirmation and that may take sometime but then again that is not mintdices problem. If the gambler sends a quick one with high fee then they will be able to play very quickly, its still not instant but at least its good enough that it might deposit in less than one hour.

If the gambler decides to not play or even withdraw after one hour instead of gambling then that's fine, mintdice will always have a lot of people who would be willing to gamble after waiting for the deposit. I doubt they would have too many people who will decide not to gamble after waiting for the confirmation, those must be rare. That way they could also have automatic withdrawal as well.

I've only ever personally seen someone hit the blue slots jackpot. Never the green let alone the red slots. I've personally played slots more than anything and I did hit the red slots 500x one time which isn't all too bad. To be clear though, so there's no disappointment, red = 10,000x and green = 1,000x. It may be too confusing and may need to be rewritten but our slot guide panel was effectively copied from Vegas slot machine table styles.

But either way, I'm looking forward to seeing you hit it sooner or later

Also, around I'd say Q2 of 2020, we plan on integrating a cool new upgrade to our slot machines that will make the jackpot hunting thing a little more exciting. It needs a little more discussion first but I think it will have some very cool ideas for all kinds of bettors.



I'll be honest, I don't personally understand Provably Fair more than at a fairly superficial level (I am not a developer). I know there are issues with our current implementation and they are already fixed on our latest software upgrade but that is presently still just on our testnet server and has not gone onto our live server yet but I assure you this problem should be resolved sooner than later. I apologize for the inconvenience in the mean time.



You're welcome and congrats on the beautiful win.

A bit of an late update, I was payed out the same day.
500x win, on a deposit of 50euro I withdrew around 2k+ euro in BTC.
Thank you and good luck. (dont gamble if you cant afford the losses, its purely luck and the odds are not in your favor).

Regarding your bet result verification, specifically Dice.
Why is the Server SEED displayed as "currently active"? It should be displayed now as the bet that I was checking was from 2 months ago 

Here's the image (screenshot date: today):


The Server SEED for that bet isn't displayed so, I can't verify it.
You're not changing the Server SEED in every bet or old bets that's why it's still "currently active"?

Yah I did eventually, too bad I hit it when I decreased my bet amount 50% but still a nice win. My next target on mintdice is to hit the jackpot of the slot game LOL, I tried it as well yesterday. I got 4 bitcoin logo few times already so I feel like it is close enough to hit 5 bitcoin logo which will give me a payout of 100,000x (high risk slots) or 10,000x (medium risk). Worth to try with small bet, so lets be the first who hit that max payout on the slot game and be one of the history of mintdice 

The way that most casinos deal with this is they have some system which analyses the deposit and it can tell whether it can be a double spend attack or not.

For example if the deposit arrives with a fee so little that it would take forever to confirm it would automatically flag the deposit and wait until it confirms with the network. Same with deposits which have inputs which were previously linked to double spend attacks. It would assume a double spend is possible and would automatically flag the deposit until it has at least one confirmation.

I also think if a deposit is sent with a replace by fee then it would also get flagged since they know that it can get resent to a different address. If a transaction is resent without that enabled I think it would get flagged by most nodes and pools and not get processed however I am not sure, been a while since I've sent a transaction with RBF not enabled.

He finally sealed the deal with quite a nice win. A lot of winning players on MintDice recently





Yes, secondly, we are also a new site and are being extra cautious in case of vulnerabilities. So far to date we haven't had a single problem, so that security side of things has gone great for us


It's still a pretty nice score, gives more to "test" with 

Actually, I also won 500.10x a while ago.


Too bad I was only testing this nice slot game with a measly 50 sats.
The God was lucky, but not that lucky I suppose. LoL

I think manually is a common concept in casinos, there has been a lot of people who have abused the automatic system with the double spending method of nonconfirmation with zero fee etc etc which goes back to the sender because the fee is not enough and it is not getting picked up by the blocks.

It means if casinos let the automated withdraw work, they would see the money coming in and then they would credit the gambler and if they lose they get their money back anyway, if they win they both get their money back plus the wins. Hence the automated system doesn't really work anymore, maybe if the confirmation process takes longer, like takes 3 confirmations to get credits but that would mean gambler can't gamble right away and their gambling hype may die.

Still unlucky to hit x1000, here is another x140 (x70 with 6 on the dice) that I got recently. I could win 0.1btc if the dice landed on x1000 with 6 on the dice lol
Not a big win but still a nice win, I'll keep on hunting the x1000 as I'm so curious because I could hit it on other sites. Hope to hit it as soon as possible before getting busted 

Simpa's overall win was astonishingly good if he cares to share what happened. Good for him

I guess mintdice is processing all the transactions manually,so worth to wait for that 500x reward.Picking up the high priority fee will make things much faster!
Its just pure luck.

wow really nice win simpa. teach me?
