Seem interesting but i am seeing quite big problem as if one player deposit and wait for few hours but as nobody comes online to make deposit and start the timer so he went offline. Now does the deposit he have made will get returned to his account? or game will continue if another player come and make deposit higher than the first player and he will win all bitcoins after 30 second timer. Have you thought of how you gonna deal with this situation?

I hope that I understood your question, Ill try to answer it, sorry if i got it wrong.

So for example you make a deposit of 0.00002 and go offline your deposit is still placed in the game and will go nowhere until someone else deposits, there is no limit on how many players can deposit in one round and if someone makes higher bet than you it's not guaranteed that he will win, you still have a % chance to win.

Please start a seperate thread for giveaway.Otherwise,this entire thread maybe moved to Games and Rounds section.Moreover,you can keep a thread reserved for future giveaway's in G & R section.

How is it provably fair when the one who deposits higher amount has more chances to win ? ::)

Yes, when I posted giveaway announcement I instantly deleted it from here.

"How is it provably fair when the one who deposits higher amount has more chances to win ? Roll Eyes"   this is not what provably fair system is for.  It is to prove that system is random and there is four elements to use for round verification.

After each round below the game you can see the button "verify" which automatically inputs necessary elements -  tickets, hash, salt and roll you can also do that manually.

You can also view more detailed information about provably fair on our website - https://bitizy.com/provably-fair

Since the result is known to the house before the game starts, could a malicious site operator not join the game with a sockpuppet at the right time in order to win the pot himself? Alternatively, could a malicious site operator not join the games that he would win right as the countdown reaches 0?

"Provably fair" does not mean that that all participants must have the same chance of winning. It seems fair that someone risking more should stand a higher chance of winning. Traditional lotteries work the same way: The more tickets you purchase, the higher your chance of winning.

 Site is being operated by 2 people non of us are allowed to gamble on bitizy.com and we would never do something like that in our opinion thats disgusting. Technically you are right, but you can take our word we would never do something like that, great reputation is really important for us, because in the future we want to build new games, community and other projects we really dont wan't to ruin it by doing disgusting things.

and kordig thank you for your support, leave your deposition address or just pm it to our forum profile.

P.S Big updates are coming out really soon

U dint say anything about how the randomness is determined!

A casino being provably fair means that players can verify that game results are determined fairly themselves. If they cannot do that and instead have to take the game operator's word for it, the game is not provably fair.

There is nothing inherently wrong with asking your customers to take your word for games being fair–brick and mortar casinos ultimate do the same, after all! But you should not advertise your game as provably fair if it is not.

Martin I think you are being wrong here, I quote "A casino being provably fair means that players can verify that game results are determined fairly themselves."  you can do that on their website, i verify every game which i have played on their site. he said he techincaly agrees that operator can see the outcome of the game and btw i think in every jackpot/raffle game operator can see the outcome its the same niche as cs go jackpot sites

You can verify that the winning ticket (relative to the number of sold tickets) was predetermined, but you cannot verify that the game operator did not join the game at the right moment using a sockpuppet in order to win the pot himself. A game in which players must trust the operator not to cheat is not provably fair.


Lotteries in which the game operator cannot know the game's outcome until it has ended do exist. The now defunct PevPot.com (https://bitcointalk.org/index.php?topic=1243970) is an example of such a game.

pevpot doesnt even work and from what ive read it doesnt look like a jackpot/raffle page. if we speek theoreticaly according to your arguments no multiplayer casino actually is  "provably fair", every gambling page owner can see the outcome and you are naive if you think otherwise, its still good that people can verify rounds.  anyway speaking about the page i really like how it looks and wish you guys best of luck on this and your future projects

Well, that is what "now defunct" means: PevPot is no longer active. Nevertheless, it is an example of a provably fair lottery where the game operator cannot gain an unfair advantage because he does not know the result before the end of the game. You can read about how it works in its thread.


Casino games are bank-backed as opposed to pool-backed, which means that any money the players win (with minor exceptions) comes from the pocket of the game operator. For this reason the game operator knowing the outcome in advance is not a problem. He could participate in the game, but he would literally be winning money from himself.

Pool-backed games such as lotteries are different. In these games, winnings are directly funded by the players and the house only takes its cut. Unlike a casino game, a lottery is not provably fair if the game operator knows the outcome in advance, as he can use this knowledge to participate in the game and unfairly disadvantage players.

What benefit does verifying rounds provide you in the game's current system?

Does it mean that those who deposited low BTC in a raffel don't have the chance of winning? Is it only those who deposited big BTC will win.

This is very exciting sites I've tried .but here because of a shortage of new gambling site so we had to wait for another player to be able to compete installing bet. but the site is fun ;D

So each rounds will only take 30 sec before it starts right? So how about if someone bet on normal rate and others bet on high rate? How can you seperate this thing? And let say if you mix this thing, are both of them have the same chance to win the same payout or may be normal rate people will get more than higher rate?

Hello, every room is separated, yesterday we had bunch of players in normal room and in mini room everything works simultaneously. So for example there is 5 players in mini room, 4 players in normal room and 2 in high they can all start their game at the same time, because non of those rooms are connected to each other. You can also check the video which user "kordig" posted you can see how the room works.

the timer starts to tick only when at least 2 players have deposited minimal amount in the same room.


If you deposit more than other users in the round you will have a higher chance of winning, we have made min - max deposits in each room so the difference between bets can't be that big. And no it's not like the only ones with high bets win, yesterday we saw bunch of users winning with only 11% chance.


We're really glad that you like our website, yeah we do not have that many players, but maybe someday :)

As it's been made clear, your site is not provably fair. There's nothing inherently wrong with having a non-provably fair game, it just requires people to trust you. But then you continue to mislead people into thinking the game is provably fair, which seems self-sabotaging. Also the actual page "provably fair" scheme doesn't really offer players any tangible assurances that the game was actually fair, except perhaps in the case they personally know all raffle participants; but even that is diminished by the use of md5 (which has been advised against using for the last 20 years)

Im no expert but i think you call got the concept of provably fair wrong, you can verify your round and make sure that tickets and everything else is correct , if site operator somehow riggs something than thats scam and interfering in the game which site operator can do in ANY gambling game.  and as far as i have seen every bitcoin page raffle page or cs go jackpot raffle pages has the same provably fair system as this one.

If you're going to shill, at least take pride in your work. All four posts of your account have been related to bitizy. I especially like your first post, posted on a competitor thread:


Which is actually before this very thread was created.


But to address the contents of your post. On other gambling sites the operator can scam, but players have the ability to detect it. If it's not possible for the operator to undetectably scam his customers, it's provably fair. If it isn't, it's not. There is simply no way to know if when you lost at bitizy you lost due to bad luck, or were ripped off. Hence bitizy is not provably fair.

Thank you for constructive criticism, we understand your concerns about current provably fair system and it will be reworked.

For users who want to test our game before making a deposit we recently added a faucet, but it's currently experiencing some issues which will be resolved soon.

On the next update we will also have a demo page so players can test the game for how long they want.

Yesterday we had 10 active players and players made 180 wins in total, thank you and if there is any other concern please feel free to contact us.

They got another topic in games and round section which was created on september 27th

Im not trying to defend anyone here i really dont care, but all the jackpot sites have the same provably fair system then why they all call it provably fair?

and its always possible to scam undetectably specially in bitcoin casinos lol

Its good to see some new sites comming in at least something fresh

If you want to have real provably fair system, why don't you try to build you raffle around blockchain?
I mean there are  already other sites which are incorporated mining hash of blocks as indicator of win in their raffles.

Our new provably fair system will be built around blockchain.

In last 2 days players have played 252 games in total and highest victory so far has been 0.02 btc. There is a lot of updates and reworks coming in next days

Been using this site for 2 days now, everything seems fine, game is really fun and guys fix that faucet asap ;D

Thanks, yeah we are working on a lot of things now, we're glad that you enjoyed our game

New week , new bets :)

last week we had total of 350 wins, hope that you all had fun!

Amazing. So you were planning to "upgrade" to blockchain powered raffle before?
Or you realized that might be better option to cut debate about Provably Fair system you are "using" now?
Anyway, you said that are "working on a lot of things now"? When will you finish it? I don't want to play until you will upgrade your site.

Hello, our provably fair system will be based on blockchain, as we said previously we take user recommendations and concerns seriously.

they should be finished by next weekend, at least we hope so, some unfortunate issues came up with our lead programmer so that's why we are having a little delay. We really want to apologize for that.

our main targets now are

- fixing faucet

- adding new provably fair system

Everything else works perfectly fine.

We are adding a lot of features that other raffle sites don't have :) - They won't be announced until release

Thank you for your patience!

Should be done by next weekend :)

I see this as peerbet.org and it was very fair so they can play with others

Thanks :)

Still lacks popularity, if there is anyway how i can help hit me up via pms

Maybe one day, our guess is that people are still waiting for some updates and that's okay! We have received many emails and pm's about how they like our website, but they want something more and we will provide our users with that. Before we make a single update we carefully test it so users don't have bad experience using our webpage :) that's why it takes some time for us to make new updates.

Thank you for all your support, if there is any more suggestion about what you would like in our website please feel free to send it via pm or type it here.

to create a gambling site becomes crowded is not easy even bitcoin gambling site that is issued for the signature campaign and for the contest is not necessarily the site becomes crowded. because a person who has gambled will settle gambling site that made him uncomfortable

Yeah well nowadays there is a lot of good gambling sites and our provided game is not that popular in bitcoin gambling yet, but we believe that raffle games can become a popular game in the future and that's why we will not stop developing bitizy.com

New week, new bets.

Recently we have been gaining popularity on the site, so huge thank you for that! hope you all are having a great time while playing at bitizy.com

Everyone is welcome and we would love to hear your suggestions.
