Just-Dice.com game is rigged

Fact: If reincarnation is true then Actor Tom Truong is Jesus Christ.

Fact: Jesus baselessly attacks anything that tries to compete with Bingo.

In the new new testament this will be the equivalent of the scene where Jesus I kicked money-changer ass in the temple:

Matthew 2, 21:12

Jesus logged on to the Just-Dice site and complained incoherently about built-in-bots to all who were betting and investing there. He overturned the tables of the investors and the benches of those selling karma.

A fan notified me recently that they've tested out the site Just-dice.com for hours and have concluded that the site is rigged.
It has a built in bot to prevent people from winning.

Gamblers beware of the site Just-dice.com you've been warned.

Translate:

I play 4 hours straight and lose.  I have good luck so I conclude it is rigged.  Must be bot.

Both you and your accusation are bullshit.  Where's your proof? And I'm pretty sure "this fan" is you

So he just drops a grenade and walks away? Fuck that guy. Nothing more needs to be said.

Oh have no fear, something tells me that bastard will rise again.

I just tossed coin. I wanted heads, but it lt landed on tails.
Conclusion: coin haves built-in bot that makes winning impossible.

Server seed generated and hashed, user has the hash.

User adds client seed after the fact, and nonce is 1,2,3......

The whole thing runs through HMAC.

So if you take the hash, add a client seed and roll, its impossible to rig.

This is why I sometimes hate the community here, people like you really try to ruin everything.

For anyone reading this, Actor_Tom_Truong is yet another lame technophobe idiot trying to further push this community into the gutter.

A "bot" can't do anything because your own rolls are predetermined, even though dooglus could look to see what outcome you may get, there is no way he can change that outcome.

I assume that someone with access to the server has access to the server seed.

Are there any safeguards in place that prevent an administrator from creating an account, using the (now known) server seed, client seed, and nonce from predicting the results and therefore reliably producing winnings over time?  Sure, assuming they are an investor, they'd be stealing from themselves, if left pocket to right is stealing, but they'd truly be stealing from the other investors.

Apologies is this has been discussed before.

Your are right, the only risk is to investors not gamblers. Dooglus (admin/owner) can look at his rolls and make a new account and just win the investors money. We do put a lot of trust in Dooglus on the investor side of things. However the gambling side is trustless.

Proof or it didn't happen ;-) hehe

There are no "real" safeguards for this particular problem. The safeguard is that no one else has access to the internals of the site except the single, lone, administrator/owner/operator (and maybe amazon AWS, if they have a clue).

All bitcoin gambling sites have this same problem. All dice sites. All card game sites. All casinos. The solution is just another problem (and will reduce speed, and reduce profitability.)

Holy。。。LOL

Not all.  If a casino is bankrolled by a single person, then this isn't an issue.

As soon as the owner gets help bankrolling the site, however, he is able to steal from his investor.

I had the idea for Just-Dice about a year before I started work on it, and put it off thinking "who would invest when they know I could cheat them".  I tried and tried to find a way to make investing provably fair, and eventually just gave up and did it anyway.

To my surprise nobody seemed to care that I could in theory cheat them.  And even now, when the profits are only 0.61% of the wagered amount when they should be 1%, people still trust me.  So that's nice.  Basically the site has earned a lot less than it 'should' have, and I could easily have stolen the difference.  I didn't, and people trust that I didn't.  Mostly.

Since 'celeste' took around 4k from the site, the profit has pretty closely followed expectation (the green line below is 3.9k below expectation; once you're 3.9k below expectation, the expectation is that you stay there...):



A couple of weeks ago I heard a rumour that some people unknown were planning to "out" me as being 'celeste', the whale who won on Just-Dice.  As far as I know, nothing ever came of that, so I don't know what that was all about.  Maybe they're saving it until their own dice site launches or some such.  So there's something to look forward to.

Also how dooglus could rig the game (but it would be super easy to spot): adjust the max bet to a lower value as soon as a (according to the previous settings) win is coming up.

Yes, that was a concern that was raised before the site launched.  As it turns out, the maximum bet is so high that nobody ever gets close to it, and reducing it to a level where it would affect anyone would be super obvious.

For casinos with a smaller bankroll however, that would be a viable way of cheating.

[Dabs]

I stand corrected. I was thinking about other people other than the owner. For both PvE and PvP, the house can always pretend to be a player. (PvE = Player vs Environment, PvP = Player vs Player)

An example of PvE = dice site with investors, such as JD and SD, and some casinos with house poker and house blackjack. PvP = those adventure games, MMORPGs, regular poker, tournament blackjack, First Person Shooters.

And I just thought of another way for dooglus to rig the game (not as easy to spot): when the next nonce is about to win, skip it. (put a zero or low bet before it and credit the low value win instead.)

That's quite easy to spot if the player never bets zero or low stakes.  I guess with clever enough algorithms I could fill in a reasonable looking low bet that matches the player's patterns.  Then it's my word against his.  "I never made that low bet".

So far the only disputes have been the opposite way around.  People betting high amounts and claiming that they didn't mean to.

A easy way around this would be to put the nonce on their betting page so they can see what nonce each bet was (alongside each bet) so any funny business would be plain as bright skies
