[cryptnroll]

I checked your website and I can't find any proof that anything here is provably fair, meaning that winners can be manipulated, everything is collected in one pot and all transactions are probably done manually.
There is cryptnroll telegram channel with only 3 members, and according to your terms of service you say that you are registered in Malta without much information.

Using website calculator I am reducing the risk and increasing chances to win, but let's see what happens if I deposit 0.01 BTC.
I would have 92.97% chance to win.... 0.000757 BTC

they are new thats why they only have 3 members so far  but in the game your going to risk 549.69 usd ( 0.01 btc ) to win  38.48 usd ( 0.000757 btc )  .

 your chances are high but you once said that the site may not be a provably fair but even if it was provably fair there is still a chance that you could loose after having that calculated chance  but im not stopping you ,  just a friendly warning goodluck  .

I welcome you to join our channel!

Can you explain on this?

2. When you send bitcoin to participate in the round do not empty your wallet! (if your transaction leaves your wallet empty you will NOT participate in the round)

So basically you should have some balance left on your wallet so that your bet wouldnt failed?

Not to brag but I'd rather stay away from sites like this, there are legitimate sites like this and has more reputation why not risk your money. Best if they just changed that rule but I still doubt if this game will be popular, good for OP with the publicity though.

That statement coming from Op is clearly trying to catch someone's attention, and I don't think this can be considered legit. Much better if we seek our luck to those famous sites which comes after our welfare and not for their own benefit. Hopefully there's a clear definition of their service, so everybody won't think it as a mess because we need to fully acquire the truth behind speculations.

PS. LOL I think the whole terms and condition is just a copycat of other website's T&C.

Does not mean to defend them (Crypt&Roll) I just have a silly question regarding this matter, what do you think if both of the sites are using "privacy policy generator" to write their policy?

Since I know that kind of service are exist on internet moreover their policy looks quite simple

I'm not familiar with such service but do you think that such service will give exactly the same words/sentences for different sites/projects?
I also doubt if this site uses such service, they claim to be a 15 years experienced group of people in this field so I have high doubt that experienced people will use such service as they should be able to create it themselves easily.

This is our first cryptocurrency game, we are very open for listening to our users, I have explained extensively on why the wallet should not stay empty, we need to identify from who we received the transaction

A: Regarding random.org
Thank you for your question, we have just launched this project with minimal investment and are testing the interest to this service.
We are indeed using the random.org platform through the official open api to select the winner. We still didn’t implement a tool for transparency, we wanted to get your feedback faster.

You should first understand the importance of true randomness and ability to verify that your game is provably fair, and I don't think using random.org and manually entering values is good enough.
It is understandable that you are just testing stuff and interest of people, but it would be much better to first use Bitcoin testnet or maybe even Lightning Network with smaller amounts until you make some improvements.
We saw many fishy games and fake btc doubler websites that people are suspecting every new website is a scam, and I am not saying your website is that, but people are just not willing to spend their bitcoins on some risky testing game website.
That is just my 2 satoshis.

Thank you for your feedback! I sincerely thought that random.org would address true randomness. Now I understand that people have issues with it, I will update on this on the upcoming days. I just want to clarify that we tested with testnet before the actual release, the system is fully operational, I invite you all to our channel (https://t.me/joinchat/TTqvJi9w8UejBv9-) to how it's working now, you don't even have to participate. I understand there were a lot of scams, I am here to convince you otherwise. Join the channel and see how it's working.

I have seen some previous rounds on your site. Does it mean, there are real players before or those are your test rounds? You have to understand that players here are more careful because we have seen a lot of projects trying to screw naive players even with this randomness stuffs. If you want to stay in the game, you will listen what others are saying here. But of course, weigh your options as well. It will take time to earn credibility and trust.

Also, what is the minimum number of transactions for a specific round to go thru?

Highly believing that those are just test or trials


Even though he would deny it then we cant still prove out if those are actual players.

That's possible, IMHO most of those services will give the same sentences depend on your configuration when generating it.
I've been trying to look for which service might they are used, it seems they generate it through https://getterms.io

I also try to generate it by myself (with random configuration) through that service and as you can see below it was completely same

To be honest they experiences are questionable since this field still related to financial problems and gaming experiences nevertheless they are not able to create their own policies.

The transactions on the transactions page are real, we gave the website to friends and family and ran some rounds. For the round to draw a lucky winner we need at least 2 transactions. If someone deposited and there only 1 transaction, the round will stay open for another 24 hours with that transaction of course.

Q: Empty wallet questions
A: ~Snipped~

You made a perfectly valid point when it comes to dealing with change addresses, outputs and multiple inputs from different addresses but perhaps you should reconsider the registration part ^{[it doesn't have to ask for a lot of things to expose someone else's identity]} while adding few more steps to ensure others could easily understand your rules...

Steps:

1. Generate unique addresses for each user as opposed to unique addresses for each round.
2. A simple registration process ^{[or just a way to submit some information]} that would allow each user to include their transaction ID ^{[based on unique deposit addresses]} + a return address in case they become the winner of the round.
^{- As long as you're able to temporarily save such information in the database [until each round is done and dusted], it doesn't even have to ask for emails or other sensitive things.}

We wanted to avoid registration at this point, because it's another step in the process, we specifically wanted to get rid of it in order to simplify the process. it is much quicker to enter the pot without it, you just deposit and your in, and there are 2 simple rules to follow. In addition to registration, the user will still have to attach his transaction to his account.
The drawback of this type of mechanism; the entire jackpot will be spread across a large number of wallets, this means that the jackpot for the winner will have to be transferred from each wallet separately, which means that a commission must be paid for each transaction. Now imagine that 20 people took part in the jackpot, the entire jackpot is stored in 20 different wallets, and in order to pay the winner his prize, you will have to make 20 different transactions.
Another factor is gas price, it sometimes gets very high +- $ 30 per transaction, the winner will lose 600$ from the jackpot. This is a high amount and many people would be deterred from participating if they see that deduction.
Nevertheless, we will, of course, consider implementing this at a later stage when gain more users and the pots will be extensively bigger.

Can anyone suggest on the "ability to verify that your game is provably fair", currently working on that. Maybe some preferred methods

[LUCKMCFLY]

I have seen the platform and it is not bad, what I do not know very well is whether to completely trust random.org, haven't you tried to try Provably Fair? it is better since it has the best acceptance within the forum, remember that here reputation represents practically everything, and there are many famous sites that use it and everything is going well.

You say that the players are friends and family, well if we trust your goodwill, what times are they available? 24 hours is impossible, do they also have some bots? for the platform to move?

[Chikito]

I have explained extensively on why the wallet should not stay empty, we need to identify from who we received the transaction

You can't identify the person when he uses a mixing service or CoinJoin wallet.

Our experience was on other projects, not cryptocurrency.

Have you implemented a provably fair system on your projects (Fintec and gaming)?

[Maus0728]

@webtricks fully explains the gist on how one can identify the fairness of every roll and how does it happen under the hood. I am not just sure on how you can properly integrate the verification to your website but you can still have a rough idea about the program algorithm. You can also check other lotto based game to get the gist on how they applied in their site.

Ps. Apologize for accusing you that you have copied your T&C, I just didn't know that such service exist.

You can start by reading how it works on Wikipedia, but most casinos are probably using some open source algorithms or blockchain hashing for that purpose.
Checking links in references will also help:

You are correct, we are currently working on a Provably Fair mechanism, I hope by next week we will have the full process so you can actually see the verification was done. We did some research, and random.org is a solid service when you are using their api to Draw a random winner (again, we will have a full description coming next week, in the meantime, we already updated FAQ on the website)
