KINGDICE.COM - Bitcoin Dice & Invest in bankroll

[DarkStar_]

Its very bad if a player put charges on a casino that "is cheating" and warn other people, if he has no proof and has not checked/asked thoroughly what the casino really does.
The client Roll is 100% generated using Browsers Javascript  Math.Random() function, which means that we have absolutely no control on it.


PS: We will soon update the verify.php page to have the actual algorithm of our provable fairness, so that there is no question about it.

Math.random() is insecure, and possible to predict, allow you to generate a hash that with a seed will cause the bettor to lose. Google it if you are unaware.

RHavar (creator of MoneyPot, a provably fair lotto and bustabit) on Math.random:

it's also using Math.random() which is also a bad idea.

Most users wouldn't know how to verify that it was generated via Javascript, and they wouldn't know unless they saw the post you just posted (I wasn't aware). I'm not sure how you can verify that it was generated via javascript, and I consider myself to have a knowledge about this stuff above average (I could be wrong). If your keeping it like this, teach your users how to verify the client roll was in fact generated by the browser, and write an open source bot that automatically checks if it was generated in the browser and records the number generated and the hash given.

Its easy for us to do any of the things you mentioned above, true. But we don't, cause we are provable fair .

Provably fair means that the bettor can prove the game was fair - I can't prove if you cheated me or not, and you just admitted that it is possible, making it not provably fair. The point of a provably fair system is so the server has no chance of cheating without being (easily) caught.

Switch to a nonce based implementation - easier to verify and removes your chance at cheating.

I like this site more and more. The addititon of the ROLL OVER button and the option to switch off the animation made it even better. Also the opportunity to claim the faucet every 20 seconds makes it exceptional among the gambling sites with a faucet.

We will soon add Faucet levels! plus the chat is on the way!

I understand your worrying. You believe (?) that we cheated on you, and that we managed to actually crack/guess your browsers Math.Random() function seed and made you lose your last bet. In this hypothetical scenario and in order to do that, the "attacker" would need to know that this client Seed has not been manually input (No way to actually know that) and secondly i totally believe that it would have taken a liiiiitle bit more "Sample" than your 39 Rolls .

In any case, the Math.Random brute forcing i find it an extravagant hypothetical scenario for sure, but i will pass this insight to the dev team and soon they will switch to a crypto related browser random function.

Please next time, since you seem to be a long time member here, be a little bit more cautious when you imply that a casino cheated on you and please don't bet with amount you can't afford to lose. We would be happy to welcome you again at the King anytime you want

I'm not saying I was cheated, but that it's definitely a possibility.

^^^


I didn't imply that you did cheat me - just that I could have been, and that I kinda suspected that you may have cheated.
Even if I did manually input it (I did at the start, or somewhere in the middle), it automatically changes after every roll (never mentioned anywhere). I can afford to lose the 0.06BTC, but if I were to lose it, I would like to lose it knowing I wasn't cheated.

How do you verify that the seed was in fact generated by your browsers' Math.random() function? I googled it and couldn't find an answer, and would like to verify that you did not tamper with my client seed. Auto betting seems to be very weak to your system, and makes it very easy to cheat, so I would like to verify that if I do auto roll, that my seeds were generated fairly (very easy because of the known pattern)

Switch to a nonce based implementation.

arent rollin.io and crypto-games.net using same changing client seed every roll system? correct me if i am wrong and i understand your suspections but someone has to enlighten this situation

Thank you for the advice regarding nonce, but please allow us to choose what want to implement and what is not really needed.

In order to verify that the client Roll is actually made by the JS you can easily View Source and find the main javascript file in: js/app-d8fb25ecd4.js .
Then on line 337:  var n = Math.floor(99.9 * Math.random())  and on line 339:  e.roll.rollClient = n .

Since the JS random number is automatically created by you, cheating in auto betting is not questionable.

I didn't say you said that we cheated, i said you implied that we did . I hope i clarified this matter for you, so that we don't have to repeat ourselves on every thread answer. After all, its a matter of trust, and I'm afraid i cannot do more to prove you that we are legit and we are here to stay.

Thanks and praise the King!

Basically you can check it by yourself by visiting the site and open the top wager tab if you are not too lazy to do it. I believe the stats is not changing too much after the competition end some hours ago.
As what I see on the leaderboard of the top wager players :
Minho : 6.xx btc
Samuel : 5.xx btc
LionVersus : 3.xxbtc

We are thinking of implementing Level-Up Faucet.. What do you guys think about it?

We are thinking of implementing Level-Up Faucet.. What do you guys think about it?

It is good idea another incentive for players to wager to reach certain level.

[panjul07]

We are thinking of implementing Level-Up Faucet.. What do you guys think about it?

It is a common feature in almost dice sites and it is attractive enough for some players. But in my opinion it is not effective enough, mostly leveling up faucet need to wager some amount of btc which is usually only whales will able to get bigger faucet amount. How about players with lower bankroll?
If you want to implement it, I hope there will be some ways to level up our faucet (not only by wagering) Maybe by being active in chat (if any), by referring active players, and some other ways. Just my 2 cents

[lite]

We are thinking of implementing Level-Up Faucet.. What do you guys think about it?

I think it'll be a nice thing for the players who gamble a lot to get something good from faucets.(random amount but something good) also please take panjul07 suggestion into consideration, it's a good idea.

Level-Up faucet is a good idea to be implemented in your site. And make 0.5 or 1 BTC wagered as the starting point for the faucet to start to increase will be better. To avoid abusers, you can limit faucet claims/day for each level.

I think it a bright and good idea that can take more people to stay and get more bonuses when they are already wagered and reached the minimum requirements.. So that for those who are gamble they have aim or goal. like wagering minimum of 0.5 btc or 1btc.. to increase the faucet bonus..
