Our games are provably fair.
No, they are not.. You just described provable results the most common used scam instrument on self proclaimed provably fair casino sites here is proof of such:
http://v20.nl/primedice/ I will explain to you why which is obvious next.
Provably Fair:1: players txid or any other input the casino has no control over including a daily site secret.
2: any site that shows you a hash of the site seed used for the next round and allows for users to provide their own seed
Provable Results:1: shows you a hash of the site seed used for the next round and does not allow users to provide their own seed.
The difference is monumental:
Operator can generate a huge sample of site seeds and client seeds and then cherry pick the results they want. There really is no actual fact or proof of randomness just proof of result.
WOW, where/how did you find that site??? I want to add it to my signature
Just another day of service, only time until these operations dry up as players go elsewhere. Funny thing is some of these RNG operations are legitimate as much as they can be, but choose to lie, manipulate odds, and trick new players as they are actually provably fair.. We will continue to call em out.
The site that you refer to, refer to a pseudo random number generator that is based on client seed and server seed.
Our games except the dice do not use this mechanism at all.
We guess that what this site is doing, is assuming that the player doesn't change his range frequently, so they presume that the next bet
will be for the same range, and they manipulate the server seed to generate results outside this range.
Note that if you'll keep changing your bet there, you will win more times.
Even if the site will give you a way to change the seed, it wont be very practical since you will not change it on every bet.
Our dice however, generate a random client seed for you on the client side (javascript code that everyone can see and verify).
so that way, predicting the player's bet wont help, since the outcome is driven from 3 factors:
1. Server seed - controlled by the casino - don't trust it unless its pre-generated and hashed before the playing session has begun.
2. Client seed - fixed on that site.
3. What will be considered as a win - the range the client select - fixed most of the times
So if 2 & 3 are fixed, and 1 is not provably pre-generated, (long time before the game play) it's easy for the casino to cheat, by generating server seed that will result in a number outside the player's range.
however, if 2 is constantly changing, with each bet, there is no way the casino can choose a server seed that will generate a result outside the range.
Scam example:
- Learning period:
1. Server picks random seeds, hash them before the roll, sends the hash to the client.
2. Client sends the fixed seed to the server + bet range (say 0-50)
3. Server calculate the result based on the server seed + client seeds - and check if it's in the range.
so far fair chance for both parties.
- Scam period
1. The server knows the client seed for the session.
2. The server assumes the client will continue to bet on the range 0 - 50.
3. The server fabricate a seed that combined with the client seed will result in a number > 50.
4. The server hash the seed and sends it to the client.
5. The client makes a bet on 0-50 and looses.
In Bitoomba this is not possible since the client seed changes with every bet.
