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

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.

Yes thats what's on my mind too, actually we may even increase the faucet every BTC wagered, or something relevant Wink

Just visited your site and these are some things I noticed .
First of all , design is cool but rolling dice takes too much time ( Many users won't know how to switch it off , the button is at the right but  there is no label to it  ) .

The leaderboard takes too much time to load , I am sure its not my connection problem . Look into it and it would be good if you consider adding Tipping system .

Level-Up faucet , I don't think it matters much .


Yeap, we are going to make it a bit more obvious the switch-off animation button Smiley . Also currently the dev team is working on implementing Chat functionality + Tipping! Smiley

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.



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

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 Wink . 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!

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


Satoshidice uses it too Smiley

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.

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.

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.



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 Wink .

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 Smiley

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!  Cool Cool

I meant I stopped betting - if I see a number that would have lost if I was betting the other way, I switch it (why it was Under 98, and than Over 1). I know for sure I didn't make a 5k satoshi bet with the new settings, so I found it very odd that the server recorded one.


I believe your provably fair system is quite flawed and makes it easy for you to cheat - the Client Roll automatically changes after every bet without telling the players (it's never mentioned on your site and the thread, and I thought it was odd when I started verifying). How do you generate the Client Roll? It would also be a fairly safe bet for you to cheat if the bettor is playing 2x or higher, as the risk of them switching is low, and the reward if they did switch is low as well.

It's easy for you to guarantee that you win if the bettor is playing with the same pattern (like I was, as the chance of me switching it around and betting the opposite if you rig it is very very slim), or if they were auto betting. If someone auto bets, you could end up generating Client Rolls that guarantee a loss for the player, and it would still verify perfectly. The only way a system like yours would work would be in a MoneyPot type situation, where the app generates the random seed, while the server generates the hash (MoneyPot). I'm not saying I was cheated, but that it's definitely a possibility.

Switch to a nonce based implementation like Just-Dice, BitSler, PrimeDice, BetKing, e.t.c. It makes it easier to verify, and removes any chance you have at cheating (except for nonce skipping, and maybe a few others, but it would be easy to prove I was cheated.)


TLDR: The server (KingDice) can cheat you if you use auto betting easily, and fairly low risk if you bet with a predictable pattern.


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