This for building a small lottery game accepting bitcoin as a payment

It shouldnt be a static one, odds or winning chance should vary on how much ticket you have bought in just like on what most lottery sites do apply on.

Take this as an example: https://crypto.games/lottery/bitcoin  ;D
Lastly, it doesnt have any house edge.

Hope you do get some idea on what i have shown.

Obviously the best odds will attract the most players.

But no one will play if the game isn't provably fair.  What is your plan to show that?

The thing is we are building a platform with no house edge, the winner will be decided by the players itself. we just charge a transaction fee for being a middle man

The more entries allowed in the lottery the better because if there's only a few entries the prize pot would be less interesting. I also agree with stomachgrowls the number of tickets available should be increased because both sides benefit from it. The chances of winning is lowered but the participants get a bigger prize if there's more tickets and the site would get more profit as well.

Probably the higher winning percentages... assuming they are cheaper(very unlikely), fool-proof and verifiable.  But I guess those with higher percentages will be costlier than the lower ones... The low price alone of those with low winning % could attract more people if they are not aware of the low chances of winning.

How about each ticket has an equal winning chance? So that if a player wants to increase his/her chances of winning, he/she will buy more tickets. It is going to be his/her option based on how much he/she really needs to win or how much he/she is willing to shell out for the game. As to the odds, isn't it just a jackpot, 1st prize, and so on?


What exactly do you mean by this? How would you do this?

The better odds, the more players will be attracted, that is logical. The question is how you can build the platforme and ensure the best for players and that everything is legitimate and trustworthy.
New platforms appear all the time but only few manage to attract and keep the players for a longer time.

I think that the 33.3% is a generous win ratio and I think many players may be fascinated by such a high chance percentage in a lottery game.While you may start out small as you say but based on the participation of people it may become a hit and it may turn into a big lottery.Of course you will have to adapt to changes if this happen.

3 and 33.3%.. that's my answer, if 3 people are playing with a total fo 33%, tat means they have at least 11% chances of winning, and in gambling regardless of what kind, more chance of winning attracts gamblers more.

Actually I am quit confuse about the question because in reality, lottery does only give a very low percentage to gamblers, lower than 1%, that's the chances of winning, and that's the reason why they can even accommodate millions of gamblers with sometimes no one wins in a single draw.

Very interesting I hope you can give us more details this, some of the lottery game are on provably fair but if you have a new algo like this one you mentioned let us have even a small information on how it's going to be run.

The higher the odds, the lower the winning chance. So it is somehow balanced. You will either go for a bigger prize or a higher probability of winning. That's fair.

Also, the higher the winning chance, the more expensive the ticket I assume. So the players will be torn between just taking the chance and pay for a cheaper ticket or trying to really make some money and pay for a more expensive one.

I agree with Vod. You can also offer odds of 99.9% in your lottery, if you don't provide a mechanism to check the outcome of the lottery, you will hardly find any players.

If you have never heard of "provably fair":

(Yes I know, you shouldn't quote Wikipedia, but the paragraph sums up the meaning very well ;) )

You can see for example here for Bustadice (https://bustadice.github.io/verifier/) how "Provably Fair" works and how it was implemented.

single ticket but expensive price ? this is new to me .  im only thinking of the traditional lottery with fix price tickets but the only way to increase the chance of winning is to buy more quantity of tickets with different numbers pick on it  but this was online so introducing new twist is still welcome   . just want to say goodluck to the op  for venturing the world of gambling   .  gambling markets are pretty competitive but still few lotto games that i saw here , so you still have a chance to shine

It would not be exciting if there are many winners on a lottery game. The most you can go is 3 winners for every 100 participants. That's a winning odd of 3%.
And there should also be limit how much a single player be able to buy on a lottery. The game of course should be provably fair. Provably fair on lottery is much easier as you can take a simple reference of future hash for the results.

Now this is going somewhere interesting. If you don't mind, would you like to share more details about your platform like what the format of P2P lottery and how players will pick winners among themselves?


But it also means only 3 players will play per game. I don't call something lottery where I can only win 3x of the ticket amount. It will be more or less gambling and there are many other games with much more interesting formats like sports bet, multiplayer dice, crash game, etc to win such odds. People buy lottery tickets to hit big jackpots. Buying ticket to win 3 times won't be fun as a lottery.


Umm! I don't see much clarity in your suggestion. It would make the game unnecessarily complicated. There cannot be multi-rates to enter same lottery. Better and easier way is to allow users to buy as many tickets as they want. Higher the number of tickets, higher the probability to win and higher the cost. Simple!

Well, in my opinion, my answer is 3% and 33.3% as this is the closest to the fact that the person who plays the lottery can win. But also because playing the lottery has a 10-11% chance of winning because this gambling class has the worst chance of winning due to the mechanics of the game. But if the lottery store has many available tickets that can be sold to lottery betters the chances are they will win, --both the lottery store and the people who play it have the same benefits. Indeed, playing the lottery is one of the fun activities of its players, it can be compared to drinking water that cannot be forgotten all day.

Then, how you run the business.

I believe still not enough the business would be running with the only charge from the transaction fee, cause every transaction already can be created with a cheap fee.

Unless if they do make fees that too high or deductions much more since this one doesnt have a house edge.
Answering up the question in talks on which one is better then of course the higher the percentage the better
which is 3 in 33.3% since people do know that they have higher chances of winning rather than being divided into
smaller parts.Business with no house edge will probably get their income in fees and theres no doubt with that because
theres no other way to generate profit.

So it means, it is better to have HE rather than charge high hidden fees, right? The project should be transparent as much as possible so players will have the trust to play on their platform. Of course, if you want to set-up a lottery game, somehow, you want to earn money and I guess, they are not doing this for charity. So better be honest as much as you can because people will dig your system if you are not telling the whole truth of your intentions.

most people find lotto game unfair just because they hardly win on here  .  we know lotto game is hard to win 

i bet this was also the reason why op is asking for odds or winning chance because he was trying to make the game more winnable   .  why not go for the small win chance anyway  ?  the higher the chance of winning the better but expect that the prize pool will be also lowered   . still better than not experiencing to win at all  .

I give my vote to 3 and 33.3%.

But I think no matter how much the odds, people will buy the ticket because they want to be the winner. Many people don't think about the odds, the percentage, the money they use, but people see what the prizes are, how much the money they can win from the lottery. If they see the prizes are so big, they will buy more ticket because they think with having so many tickets, that can increase their chance to win the prizes.

But for people who care about the odds and the percentage, they will calculate how big their chance to win the prizes, and if they think that they don't have a chance to win, they will not buy many tickets, but they will only participate for fun.

Yes it's quite a good game, but the winning chances increase only if I buy more tickets let's say if I buy 6 tickets I will get a chance of 28% to win, but in our game every winning ticket will have minimum odds of 3 and with zero house edge

Yes that is why we want to build a transparent game where the players will be deciding the number that  wins

We are not going to limit the number of tickets but the game takes place every 24 hours, so we will welcome any number of tickets in that time period.

Yes we will be keeping each ticket at 0.001 which is going to be $ 10 and the minimum winning odds of 3 with winning percentage of 33.3%

No, we are not going to have any first, second, or third price.

We are just going to have 3 numbers displayed for the people to select, a user can select only one number and at the end of the day the number which has got less number of selections is going to win and the money on the other two numbers will be distributed to the winning number calculating the odds.

Yes that's going to be tough but members like you can help us by reviewing the platform once it's released :).

Yes you are true the winning percentage of 33.3% will obviously attract the people but our minimum bet would be 0.001 BTC which is nearly $ 10 and the minimum winning odds of 3.

We can't say that we are a lottery platform because as you told instead of 3 players we are going to have 3 numbers and a user can select any one number, at the end of the day the number which has got least selections will be the winner and the bets will be distributed proportionally.

Of course, we will try to give free tickets to the people present in this thread

Yes that's what we are trying to explore.

We can prove that we are fair, but the game that we are introducing doesn't require that because the winner is decided by the users. If there no house edge what's the point of proving fair. casinos have house edge of 1%

Yes we are trying to explore that, and yes we are going to have fixed price tickets with a twist in it ;D.

Yes people requires excitement as well some winnings so we are trying to balance them

Yes I understand so we are going to have one lottery per day initially and as we progress we are going to have more lotteries per day

Yes we know that and we are going to charge 10% as the betting fee

Mate please kindly stick to the forum rules. You have bumped this thread 16times in a row today.
It is obviously against the rules where you are allowed to bump your own topic once every 24 hours.

Sorry for out of topic, just giving you a friendly reminder.

So, it's like you are saying I already won 1 number since I can decide on it?
Okay, this looks interesting.
Maybe you should start a beta test and let people try it out.
That way you could pull more gamblers to come, it's an easy invitation with free advertisement.

Edit: You also know there is a possibility of cheating here for a group of people?

Hey! Sorry man. I really didn't think of it I just wanted to clarify their doubts. Won't repeat this again

instead of answering every one individually  you can quote all their post in one reply only  in that case you will not bumping your thread for answering every one.

Hows the game now?have you started and what is the feedback?Lottery is one of the most simplest and played Gambling all over the world so i wonder if you made a successful business out of it.

Update about the game,willing to participate if you have still existing.

I submitted my vote base on what I want, of course most of the players want to have a better or higher percentage to win the lottery game if possible so I voted for 33.3%. But we are talking about lottery here so I wonder how a certain player can get a 33.3 winning percentage if in case he/she will only bought one ticket for the lottery.

So I am a little bit puzzled to what you are planning because if you want to create a unique style of lottery game then it will be good as long as it is fair to all
the players or gamblers who will join it. Because we know how the lottery works, the more the entry the lesser percentage that you get and there is no fix winning percentage at all as the percentage will change every now and then once there are more entries to join.

^ Please read the rules first for your own safety and your thread as well. It is rule number 32, https://bitcointalk.org/index.php?topic=703657.0. Just edit your previous post and make it 1 reply.
The chances of winning in lotteries is very small beyond 10% probably an exact rate of the chances of winning per user. The big prize pool makes gamblers lurking especially if the amount is thousands of dollar which pretty good, once you will win it will really change your life.

Yeah you just bumped up a thread which is almost 4 months inactive just to tell him about that posting violation yet your reply doesn't even connected nor relevant on whats been talked into this thread itself.
So you should at least to mirror out also your mistake on here.

On topic reply about lottery game then I did chose that 3 of 33.3%.. We know the higher the chance the better yet it do only requires 3 person for such lottery to proceed or to be drawn.

The question is, how much would be deducted as on sites commission?

I voted for the 10 and 10%. In my opinion lotteries should be more risky than other games. You want to get a lot of people in so the winnings are very high. If you are just looking for a quick double up I would recommend playing other games like dice or roulette.

This is just my personal preference but why I notice among friends and colleagues is that they are usually not interest in lotteries. Only when the jackpot is close to an all time high the interest in lotteries spread around and everyone starts playing. Becoming a millionaire overnight is wfat drives many people into lotteries.

Ohh welcome to the community and Hope you have conducted the Bitcoin accepting game.

Company name?where can we reach out the team and how to check your site?

perhaps there are ANN thread?

Lottery can be profitable business but of course added other games like Bingo and some card games like BlackJack and Poker.

Dice and Roulette and also Slot machine,you cannot succeed having single game offered.

better have more than not being followed by gamblers because of limited games.

Out of all the online gambling I'd have to say lotteries are the most prone to the results favouring those the organiser of the lotto.  Unlike other online games which can be "proven" to be fair, how do you "prove" the results?  A screen grab of random.org selecting a random number?  There's no way to interdependently verify the results, so I steer well clear of such wagers.
