The funny is, people who won the raffle still complaining about the raffle and me, who never win a single raffle not complaining, rofl.

Maybe they only give a suggestion I  also never won the lottery in this period and I feel fine

By the way lottery still available ? I see in sportsbet.io  (21:08 Olympics Redraw) Prize 1500 mbtc
How to participate in the lottery is no games available in Olympics

[cazkooo]

Anyone saw the olympic 17-21 august lottery redraw in 5 hours or so in the site? I cant figure out how to get any ticket to join these since all of tickets has been used on the previous lottery and Im not sure why is there a redraw again this time. Well with the olympic ended there is no way that somone could get ticket anymore but I saw around 170+ tickets there

edit : yep monsterv beat me to it

I think the redraw lottery is for those who bet yesterday but did not receive the tickets for the last lottery (17-21). I received one ticket for the redraw, and I believe I received it for my bets on the Final Basketball match.

I never win in the raffle, but not complain too
maybe I'm not enough luck in this lottery.

I see the EPL leaderboard is updated already, but seems that it is only updated for the top positions only. I have won some mbtc last Saturday but my point is still the same with the last week update. Means that my winning last Saturday is not count towards the leaderboard? Or perhaps the update is not finished yet?

Should be all updated

Just a typo. You ought to say 'get your English right'. Grammar is to do with structure of sentences and stuff as far as I know. This puts you in the same position.

Now,I can see personal hate coming out of that post.Did I hurt your emotions intentionally/unintentionally ?

huh

I have heard that accusation before.
I don't think the lottery is provably fair or it can ever be made provably fair.

Well,you really need to stop living under the rock and get your facts right.Provable/Verifiable lotteries do exists.What have you known about the RNG's ? There are more than 100 algos precisely crafted out by our so called "Mathematicians".You ought to prove all of them wrong by saying "it can ever be made fair".Do research about the RNG's,website devs can implement one of the existing algos to propose fairness.

I am sorry, I believe you are wrong there. (Advance apology. not hurting your feelings )
Not possible because you cannot verify a username is real or fake. Making this truly provably fair requires a very high level of transparency.

You can have some fancy blocks and hashes and any other thing you like, it won't make the lottery 100% provably fair.
Well something is better than nothing. Any attempt on making it better is appreciated.

I am sure Sportsbet offers better odds than Directbet.

Why are you backing up the site without concluding the facts ? Are you associated with them ?Their spokesperson ? Or just the urge to have a negative opinions against whatever is doubted about the website ?

My statement is correct, isn't it?

Everyone is good with this method from DarkStar_?

1. Publish the list of tickets and who has which ticket, a bit before the actual draw. Make sure that tickets are numbered.
2. Wait for a specific block hash for the drawing. Once the block comes, take the last few digits of the block hash (maybe 7?) and convert it to a decimal, by using it as a hexadecimal. Next, use the number that you get and apply modulus (number of tickets - 1) to that number. You should get a number between 0 and the number of tickets, minus one. Add one to the number, and you have your first winner.  You can get the other winners in other blocks, or if that takes too long, use the last 8 digits, than 9, e.t.c repeating the entire process I just outlined.

Here is an example of the method I outlined:

For this example, I will be using the block that was mined right before this post (block 426230). Normally, a block that hasn't been mined would be used, but for convenience, I will use an already mined one.
The has of the block 426230 is

Code:
000000000000000000dd8a7bb73190bd8574df5f18966347a2094049e28c8cab
The last 7 characters are 28c8cab, and when converted to a decimal gives 42765483. Here is my imaginary ticket list (published before the block is mined)

Code:
1: darkstar
2: person2
3: person3
4: person4
5: person5
42765483 % 4 gives 3. 3+1 = 4, so person 4 would have won the 1 BTC prize in this case.

I have a buddy who could build this as long as he gets to publish it open source on Github, send me a PM and we'll talk

The final promotional Lottery draw of 2016 Olympics is now over. Too bad I did not win anything this time.

Now I am waiting for sportsbet to settle my bets, because I still have 2 Olympic bets set as 'Pending'.

All pending bets are now settled. Can you please let me know if you are all set?

Yes, thank you. All my bets are now processed and settled.

You should talk to their live support so they could request their graders to settle your olympic bets.

I assume you meant "now" processed and settled

Shouldn't you apply modulus (number of tickets)? Why - 1?

Because modulus (number of tickets) has a chance of giving a 0, so this is countered by adding one to the final result. Granted, they could just give people ticket #0, but it might cause confusion and isn't very hard just add 1.
Without -1: Range of 0 - # Of Tickets - 1
With -1: Range of 1 - # Of Tickets

Edit: nvm, just add one the the answer. My bad.

Sportsbet.io, have you decided whether you are going to use multiple block hashs, more digits or a combo of both?

Although Darkstar has come up with a nice and simple method,there are still a few problems with it.Let me update this post later.I'm thinking of implementing one of the known and already proved Random Number Generator Algorithms.

Those probably won't work in this case. If your thinking of using something like a server hash of a number, which has modulus applied to get the number of the winner, sportsbet.io could easily throw a few fake accounts in at the end to make one of their alts win. Many of the already proved ones won't work, since sportsbet.io would know the outcome before the draw. My solution would still be vulnerable against them adding fake accounts (what method isn't?), but they can't 'rig' it. They can make it very likely for them to win (might raise suspicion), but they can't guarantee a win. What other problems are there? Also, the block hash is random, and although a Bitcoin miner could orphan a losing block hash for them at sportsbet.io, it wouldn't be worth it since the block reward is 12.5 BTC (+ fees).

Get your idea up there then we'll figure out what to do based on what the community says

[trinaldao]

I want to give a little advice, when made a lot of teams for parlay. but I am confused which team is winning and losing. I hope you puts the information about it. I was able to look for the result, but I hope you make it easier.

I agree with adding 1 to the result of modulus. I don't agree with removing 1 from number of tickets for applying modulus.

That sort of guarantees the last ticket a zero chance of winning anything.


To illustrate,
Block number : X
Number of tickets : 100

Wrong:
X % 99 gives 99 possible results from 0 to 98
Adding one to the result gives 1 to 99. (100th ticket is excluded.)

Correct:
X % 100.
