Bitcoin Forum

https://mybitcoinlottery.com (https://mybitcoinlottery.com) is in beta, looking to see how much interest is generated from this type of lottery:

• Easy to play
• Simple format
• Totally free
• No membership, registration or login required
• Frequent drawings
• Multiple chances to win
• Results are published in real-time

We look forward to any feedback on how we can improve.

Provably fair? I guess not:


How can it be random when when it's based on how much a player bet? Contradictory. Can you explain further?

For example, if you bet 10,000 Satoshi and another player bets 1,000 Satoshi, you have 10 times the chance to win than the other player.  The winning tickets are still picked at random so even though the other player has a much smaller chance of winning, they could still win while you might not.

Why is it that in your site, you have this phrase: "Again, this isn't real, we don't have a gaming license."

Care to explain?

And I think this looks like a faucet to me but with a simple twist of having a lottery.

I entered your page and I've seen that the player that has paid 10000 satoshi has 100% chance to win while the one with 10 satoshi has 0%.
I suggest you start learning about floating point operations and provably fair drawing. What I see there is, sorry, a (bad) joke.

Hi - thanks for your reply.  The site is simply a proof of concept (for now) to learn if people would actually be interested in what is intended to be the simplest of lottery games.  I do not have a gaming license, so this is not a functioning lottery.  If enough interest is gained, I would apply for a gaming license and make the lottery functional.

The site is not a faucet.  My intention is to make it very clear all over the site that this is only a concept for a lottery.

Hi - thank you for your feedback.  I will have to try the site with Tor Browser.

Since at the moment the site is only a proof of concept, I used a .net random number generator, that's it.  There is no house, the players play with each other and not the house, but I would still need to make the randomness verifiable.  I would generate a hash before the player submits the transaction, then verify the match after the transaction.  I assume that would be a sufficient mechanism to satisfy the bitcoin lottery community?

I'm looking forward to win in this bitcoin lottery thing. Since it's free and on beta more and more prizes waiting for us. I just visited the site and there is somebody with a 99% win rate.

Just tried to put some random inputs and it directed me to a lot of codes that are not clear to me. Probably, that's one of the things you need to fix. Try to add at least just a pop up message for that like, "invalid bitcoin address."

I see that the site is just like a test run or a concept for lottery. I guess this would be good if the lottery is provably fair. It might catch a lot of gamblers attention if you will be able to run the web site without problem, such as deposits and withdrawals.

Firstly welcome to the gambling industry
Secondly, if you ask about how much the interest of such lottery game then I can say that the interest is not that much here. There are many other similar lotteries since few years ago but no one can survive due to lack of interest.
Third, your site is so simple which is good but also a bit not attractive to catch gambler's eyes.
Last but not least, Regarding the prize distribution of your lottery based on the Finished games. The total prize for 3 winners is exactly the same as the total prizepool. Does it mean that you do not take any fees when it will be live?

I am afraid your suggestions won't be enough to help op out since the competition is intense and this website is basically a bad experiment at present.

I highly doubt that this website can become successful when there are way better legitimate alternatives out there in the crypto space.

You will have a hard time making this lottery site of your to gain gamblers or bettors. I still don't understand how much I could actually win if I bet. There should be a specific amount that can be won by bettors and not divide the pot into 3 winners (as for now based on the site).

How will your lottery site be fair when the player with the big bet amount have 100% assurance of winning and the one with a small amount have almost 0% winning  assurance, what is you algorithm do you use in doing your lottery calculation?

Its okay if he's going to find it hard to make his lottery into fame. As he said, this is just a test and likely a survey on how gamblers are going to be interested with the lottery that he has created. OP is playing safe before running his own lottery business, he needs verification from the community and will base the result of it from the feedbacks that he will receive from the people who will try it out. I'll try it out OP and would probably give my opinion about your site.

It's safe to say that this lottery is a beta so it will be a hard time for him finding gamblers. And that thing is pretty much a common thing to a starting business.

Yeah, a simple lottery with a very simple website design too. I've seen this before but this thing would eventually fail for sure. Not to be soo negative but this would always be the destiny of these lottery kind of games.

It is a lottery with no fixed amount of entry but limited to 3 entries/players per round, so there is no fixed amount that you can win but it is clear that the prize distribution is 80%-15%-5%


Why it should not be divided into 3 winners? It is usual in any lottery sites to have more than 1 winner. More winners = more chance to win something back, that's the logic.



No one will have 100% winning chance in any lotteries unless he/she is the only one who spend some money on the pot.


All lotteries works like this, the higher you bet or the more tickets you have = higher chance for you to win the lottery. Probability of winning has nothing to do with provably fair IMO, the main problem is about how they will do the draw? Random provably fair system should be implemented to make it fair for all users.

Welcome to Bitcoin and welcome to gambling. You can see you found the right place for feedback but let me say something else here,,, lotteries will not work on this particular type of gamblers (crypto gamblers).

You can make lottery a section of a casino, or a part of the offering. This works very well in some sites like Freebitcoin, it adds an aspect of gambling. But standalone crypto lotteries have all been tried many times with no good success,,, mainly because people do not like waiting,,, and people do not believe in the provably fair,,, and people do not like high fees when the standard of crypto is 1% or below.

Funny but rightly asked question. I think with my common knowledge that the reason that big play gets 100% while small bet gets zero % is to prompt people to play bigger with the hope of getting better chance for good % when they win but, you don't get deceived to bet what amount you want to bet because, betting is always lucky game.

Lately someone here had an idea of 0% house edge dice and was asking for donation, now this one is asking for donation. OP better to set house edge over 0% to get some profit, no one will donate to casino/lottery and to my mind it's even unethical when casino/lottery asks for it.
Now what can we say about demand: I think it's very, very low because there were similar ideas with enough funds but non of them succeed, well, overally demand is very low and can say the same about trust.

You have quoted my post but not everything. You clearly didn't understand what I just said. It would be best if there was a specific amount to be won just like in freebitco.in lottery.

Where is the logic in your post?

This can't be called the simplest bitcoin lottery because of the chances of winning on the gambling platform. Although it inspire my humble self because it require no registration before play. Also, like the price distribution of the winnings, kudos to the team behind this project, wish you success.

I am sorry to say that even spending about 15 mins on your lottery site, i am still unable to figure out how this lottery system works ?
As soon as 3 players deposits, we have a lottery result announced ? How can be it fair if a one person depoist more amount so he will automatically win ?

Also you need to add a help section on your site as nothing is clear on how to deposit etc.  ???

Your website isn't working in my mobile crome browser. While the home page is opening fine, as sion as I am trying to enter a lottery and clicking on Submit, it returns a server error. You may want to look at this!

Yeah it also reminds me of Freebitco.in (https://freebitco.in) .
And I also have a question to OP how can it be totally free?
And how much could we win?
I visited the website but there is no more info about the winning prize except that the 1st place would receive 80%

And you do not even understand how freebitcoin lotteries works. There is no specific amount to be won in freebitco.in as the prize is progressive depends on how many tickets are sold/earned.
Even worst, the lottery on this site works the same. The prize depends on how many satoshis sent to the pool. It shows that you dont understand about lottery at all.

There is no fixed amount of bitcoin/satoshi that the winner can get after winning the lottery that is why when you go to the site you'll fill up your bitcoin address and how many satoshi you'll bet then that satoshi will be added to the prize pool as the reward for the winner but you can see/check how much is the reward added in all before the winner will be drawn. This is what caught my attention same as you guys "Again, this isn't real, we don't have a gaming license." in which I know lottery is also a game.

Yes, someone had bet 10000 satoshi while another player bet only 10 satoshi.  The 3rd player bet 0 satoshi and thus had a 0% chance of winning.  Check out game results for Game ID 9b7a8a6e-a83e-4dc6-a2f9-837ac110e1c9


I've done some better validations, including "Invalid Bitcoin address" and Satoshi must be >0.

Thank you very much for your feedback!

Hi there - thanks for your response.  Yes, at this point the website is only a proof of concept.  It could easily be made live with real transactions if it turns out there is enough interest in the simplicity of the concept.  Currently the randomization is just using the .net random function, but if I go live I would make it provably fair with hash matching before and after each transaction.  Thanks again!  Yours and everyone's feedback is very helpful!

lets face the reality here. a casino or lottery business asking for donation from the community? epic fail!
im not judging them but a new gambling site should have their own money to start with. how can the gamblers trust their financial side?
also the dev might want to improve his site. we are not looking for a grandeur entrance but at least an appealing website...

Hello - thanks for your warm welcome.  It may be true that people won't have interest in this lottery, so I'm glad to get the feedback early on before dumping a lot of cash into the project.  If nothing else, I'm enjoying the experience.  If it would go live, I would beautify the site to attract players, but I am really going for absolute simplicity, transparency and frequency of the rounds (the rounds are played as fast as the players want to play them).

You are correct to intuit that the total prize for 3 winners is exactly the same as the total prize pool, which means there are no fees.  My vision is that this lottery is totally free to play, and players are not playing against the house, they are simply playing each other.  I do not want to store any PII of the players, and I do not want to create a barrier to entry by charging a fee to play.  The idea is to generate traffic by being the simplest and barrier free lottery available.

If anything I may consider creating a charity pot, and direct a small % (1%?) of each game to give to a charity (or charities), also via Bitcoin transactions that would be public and traceable.

Hi, by what are you saying there, thats not probability fair at all, can you please elaborate a little more how is that calculated, and most of all, how can we check that too ?
Thank you

Hello - thank you for your feedback and hopefully I can answer your question here.

It is currently set to 3 entries per round producing 3 winners taking 80/15/5 of the entire pot (ultimately producing a single winner and essentially two losers).  It could be 5 entries per round, 100 entries per round or 1000 entries per round.  Why must the lottery pay out a specific amount?  Players can buy multiple tickets in most lotteries, which increases the pot and increases their probability of winning.  Think of setting your own satoshi amount as buying multiple tickets to acheive the same effect.

Hello and thank you for your reply.  I don't see it differently than any lottery where players may purchase an unlimited amount of tickets.  Imagine you play a lottery, and buy 1 ticket.  Your friend also buys 1 ticket.  Finally a third player decides to play and purchases 998 tickets.  Wouldn't it be fair that his odds of winning are 99.8% while yours and your friends' odds are 0.1% each?  Doesn't buying multiple tickets in any lottery increase your odds of winning?

If you're asking how we could keep people from playing that way, there could be multiple versions of the lottery with different entry limits set, and different numbers of entries that would make a round.  I'm certainly open to suggestions.

Thank you livingfree.  You've got it exactly right.  I appreciate your feedback.

Hello and thank you for your reply.  You're not being negative by providing this feedback, and it is much appreciated.  As the site is a proof of concept to learn if interest in this type of lottery could be created, one possible good outcome here is that if there is no interest I would not have wasted excessive time and money on something that won't fly.

Please kindly stop bumping your own thread multiple times in a row, you can reply those posts in single post. Bumping thread is allowed once per 24 hours, so you have just done something against the forum rules. Dont be offended, it is just a friendly advise. Your account might be banned if you do it regularly.

It is always the first tickets that is hard for any lottery, I mean you are building something that has over a billion dollars in many countries so do not be really shocked by the fact that the market is sutured and you are gonna have hard time making people believe in this project and get customers.

The problem is, if you have 1000 people buying tickets than you are not gonna have hard time than finding more people on top of that, but finding that first 1000 customers gonna be the biggest challenge, if you could establish yourself as a lottery and get your name heard and everyone knows you than it will become super easy to continue the operation, just focus on that first customers that will buy the tickets and than promoting their wins and after that it is gonna be easy.

Hi and thanks for your feedback..  Out of curiosity, what do you consider unethical about a donate button being on a casino/lottery site?  I had not considered that.

You might be totally right about the demand (and I hear the same from others on the thread), which is why I made this a proof of concept before diving into major investments in time and money.  That's mainly why I started this thread, and I'm very thankful for the feedback so far.

My apologies - I did not realize that was a problem, and was only trying to reply to all the questions.  Here we go to answer multiple posts in a single thread.


Hi Okala - How would it be fair that a player with a big bet has equal chance of winning than a player with a small bet?  I believe the probability of winning the lottery being tied to the size of the bet is as fair as it could possibly get.

Thanks for your feedback proTECH77.  No registration required is a big point, as I haven't seen many other sites that don't require registration.  If you don't like it, you're not tied to it via registration, so you can just go... and there's never any chance that anyone's identity could ever be compromised (as far as I can imagine).

But a bigger question... how could this lottery possibly be any simpler?  That's what I'm aiming for... to be the simplest.


Hi Nauane, no need to apologize, I'm just trying to get feedback as I'm sure the concept is nowhere near perfect. 

Yes, after 3 bets are made, that round will be over, and the next transaction will start the next round.  The game results are always listed at the bottom of the site.  Regarding your question if a player deposits more amounts, how is that any different from a traditional lottery where a player buys multiple tickets to increase his odds of winning?  He's putting more on the line than the other players, so he should have a better chance of winning.

I'm not sure how I could make the depositing of bitcoin into the lottery much more straight-forward.  There are two text boxes.  The first is your bitcoin address, and the second is how many Satoshi you want to bet.  Can I ask what is confusing about that?


Thank you for letting me know, there was a bug during the entry submission that I've fixed if you care to give it another go!


Hi xvids - thanks for your questions!  At the moment, I have literally no costs to maintain this site.  The cost would be a gaming license if I choose to make the site live.  If I did it I would find alternate revenue streams... place ads, sell t-shirts, develop another game that does have a house edge, whatever.  At the moment though, my vision is to have the simplest lottery possible, that is totally free to the players.

Regarding how much a player can win, the answer is based on how much the players bet.  If 3 players each bet 1 BTC, then the total pot would be 3 BTC and would be split (not evenly) among the 3 players.  I could make any variant of the game... there could versions that have 5 players, 10 players, 100 players per round.  There could be versions that have min/max bet limits so players can be sure their bets won't get poached by a high roller... there could be versions where the pot is split at different percentages (currently I have it set at 3 winners, split by 80/15/5%)... there are a lot of directions this type of game could go.



P.S. Thanks to Bitinity for the advice on not bumping the thread!

First 1000? No, they must focus on how they would get even first 100 players into this lottery and saying up that this is somehow saturated and people would always prefer on joining local lotteries than on online ones.

Don't mention it but do follow the forum rules when it comes to posting consecutively. You can merge your reply with other posts by quoting it and incuding it with just one reply.

First impression your website is clean and simple for lottery games but need some improvement to make your website attractive I see some winning player with a low prize.

"Finished Games
As soon as enough entries are submitted, the game automatically ends and the winners are picked at random. Probability of winning is based on how many Satoshi are bet by each Player."

If the minimum entries not met what is your plan for those people entry the game? And the probability of winning need to change.

You website looks good because it's simple and there are no rules for entering the lottery. The problem is there are a lot of disadvantages that your website has compared to other lottery sites.
1)It is not probably fair
2)The design is way to simple and usually gamblers tend to avoid that
3)Lack of trust. Because of number 2 most people will think this is a scam since almost anyone with some basic web development skills could created it so why would they send money to a completely new website built in less than 10 minutes

I suggest one of the most simplest bitcoin lottery or betting game that consist a lottery is just playing a roulette. Try playing roulette in our newest gambling gaming (https://vegascasino.io/casino/video-slots/crazy-bananas?utm_source=cccb) online vegas casino. You can bet your coins and win a lot of prizes. Join and play our roulette to see more good prizes.

Thank you for giving us a great feedback from your experience playing our roulette in our online casino. Hope that your success and more money to come especially more win to come with you.

Good Luck to you colleague.

We are doing pretty much same things but we use autonomous smart contract on ETH platform.

And we have more steps and each ticket is equal, I mean of course the more tickets you have the higher the chances are but it does not guarantee winning.

Will also do ANN soon after some improvements.

Good to read feedbacks especially about simplicity. Simplicity is what most of gambling websites lack. Too many actions like sign up etc.

Do you have any plan when you want to launch your website officially? I will like to know about that, and I think if you can promote your site into many websites, you will gain more visitor to play the games. Although your games are simple and easy to play, if you cannot bring more visitor, then I don't think that you can make money too.

Will wait for Ann thread please provide as more information regarding to your lottery website, do you also consider to do some promotion like bounty campaign? Your website is clean compare to some lottery website I tried but you need to take advantages on your platform security.

Maybe he should also enrolled among those gaming and gambling sites that are now bring there websites for signatures campaigns and that will drive visitors to his sites and as such many players will play if it is as simple as you said.

I am new to gambling and yes this chance would help me more to have a good experience. Will register and try using the sites following the instruction given to the beginners and then will go ahead with small amount to gamble. Wish to try my chance to get few prices as well. Lets see.

I just visited the website and seems that the last 2 games has only 1 player .
Then the 20% of the bet would be on your pocket right?
I mean why wouldn't you just cancel or postpone the game instead of letting them continue the gambler would only lose 20% of their bet .

As mentioned clearly on the site, all those games are not real as they are still in beta. Those games are just to show how the lottery works.
Indeed once it goes live and there is only one player, then the game should be canceled and send the money back to the user 100%

Well I guess your right my mistake again sorry ,
I wonder when would they launch the game but it seems good for me now I never really won in any lottery so maybe this could be the first for me.

The site is still at the beta?
It has been a month since you introduce it to us but it is still in beta or the project has already been abandoned?

Here is another new bitcoin lottery. The site is so simple and cheap what's the possibilities of paying out winnings to winners, am guessing there is no so much capital in your purse judging by the fact that the project is in need of support.
Rather than support why don't the project present it in the format of a partnership this would be more effective

I will like to commend you for this and were it is fully functional we would see how this would be. Many lofted ideas like this has been abandoned by the developers and I will encourage you to really continue no matter the challenge.

Needs to wait for any updates coming from OP or the team behind this site, as the site still been uncleared if there's still a working team who's keeping
this site to work or it's already been forgotten, any news or any development from the team here?

ok, this looks good. right now it seems like to be a beta version of the site. I understand it looks good and works well. maybe there are some issues with the wining algorithm but I like the site. good to see new developers contributing their time on the digital side of the internet.

That's also have I see it, lotteries are to slow for most crypto users, it's great that you can gamble on lottery numbers with crypto, but it's just to slow for most crypto gamblers.

More bitcoin lotteries have been getting into existence, as a level higher to the same now registration free lottery service have come into reality. We've got sports betting access without any form of registration and the same is now possible with lottery service.

how many of them are anywhere near popular?
there is literally a graveyard of them somewhere at pages 30 to 50 here
I am sure I saw at least twenty of them past several month and not a single one is popular
well except for 8bet which is doing well , actually
a project like OP's though has no future since there is 0 initial invetment and the concept is not good enough to attract investors or players

I'm a bit confuse about your mechanics and calculation. Why is it that players with higher bets has a higher chances of winning? Isn't it unfair for those who have a lower bets?
I just want to understand how fair the game goes on that part.
However, your site looks great and user friendly. I hope you would that have great promotions in the future as well.

One thing that pisses me off about sites is when they are being slow in loading, I hate slow sites and that automatically kills the interest I have ,anyway. The explanation you have here is not really clear. Stop saying it is totally free when people still.needs money to be able to play a part in the game. Lol, why should you say it is totally free, before were you supposed to charge them a monthly and weekly fees? So correct the explanation you have made . And there are multiple chances of winning , it is based on how much you invest, cause the higher you throw in, the more your win rate increases. Anyway, it's good. And it seems legit ,though I haven't tried it yet.

Because it is basically like a raffle, the more money you spend or the more tickets you have the higher chance you will win the game. Just like other similar lottery/raffle game. Where is the unfair thing? If you say that it is unfair to those who have lower bets or lower number of tickets (lottery in general), then it means that you want a lottery game where all players get the same winning chance. If I'm right, then you should try to find lottery with fixed prize of the ticket and there is a rule that one ticket per person only.
If in this kind of lottery with no fixed prize of amount that you should spend but you want to have the same/equal winning chance then it wont be fair for those who have bigger bets. If you want to have equal winning chance in this lottery then you should bet the same amount as other players. By the way, the site seems to be abandoned already. OP is not active anymore, so lets just leave it. My main idea is that fairness on lottery game is not about how much the amount you bet compared to others but it should be about how the site draw the winner(s).

How about the status of this project there is not yet live version released it seems its still under Beta . Team is taking lots of time to go live .The features they mentioned are really good . But how they compete with Freebitco.in
