Truly one of the best player friendly sportsbooks out there.
Received reward of leaderboard competition. thank you sportsbet.io
although a little disappointed with the end result, I think at least I can be in the top rank of 30 and get 0.125, but ended up at rank 33 with reward 50mbtc. well, not bad.

after the Premier league promotions Leaderboard ended. Do you have plans for the same competition? maybe not only the Premier league, including all leagues such as the league italy, spain, germany and others.
Agreed, very interesting idea. Leaderboard for all soccer league in the future. we can made bet for every soccer league and still have chance to get leaderboard.
CANT WAIT TO RECEIVE THE REWARD YEAY ! 
How much you should get from the leaderboard competition? As I see the leaderboard is not updated again, its been a while after the last match of Manchester City vs Westham.
last update it will updated a day/two days after last match.
i hope i will maintain the leaderboard position and win around 500mbtc

I thought of the chained winners originally, but I didn't think many people would like it. It is simpler though.
The probability is the same.
I am okay with using the hash of the next block and the succeeding ones.I don't agree. The odds of a ticket winning are exactly the same. If house adds a certain amount of tickets, it has the exact same probability of winning any prizes under any method.
If another method is used (without chained winners), sportsbet.io can't guarantee a winner.

It is really simple. If you cannot predict x, how good are you at predicting x + 1?
The probability of correctly predicting x = the probability of correctly predicting x + 1 = the probability of correctly predicting x - 6 = whatever
On another note, the higher the number of characters we take, the less is the (insignificantly tiny) advantage of the first tickets over the last. How about 25 last characters of the hash?

The reasoning behind this is that they could put 13 tickets in for every 13 real tickets, and guarantee winning half the prizes
Just to make my point clear again,
every one in the 26 tickets have an equal chance of winning the first prize.
every one in the remaining 25 tickets have an equal chance of winning the second prize.
every one in the remaining 24 tickets have an equal chance of winning the third prize.
On the assumption that all prizes are equal, they get 50% more or less in the relatively long term. Adding tickets don't cost. There is no risk involved for them in both the cases.

I am okay with using the hash of the next block and the succeeding ones.Example:
Block 1 - Last 10 characters for the first place
Block 2 - last 8, 9, 10, 11, 12 characters of the hash
Block 3 - same as above
Block 4 - same as above
Block 5 - same as above
Block 6 - same as above
Waiting 26 blocks might be a huge pain.
Sounds great to me. Regarding the second point, the player doesn't have to get a ticket based on the time he makes a bet, the list just has the be posted before the drawing takes place (preferably a few hours before), so people can verify their ticket number. While sportsbet.io could change your ticket number, there really isn't any point unless they have lucky numbers that they want their alts to have xD (assuming they have fake accounts).
Doesnt seem like there are any problems.

It is not necessary, yeah. I just added it so it will need a bit effort on their part to add fake tickets. (Not saying they do it or anything - I trust them with it, just that a 'provably fair' system should prevent it. Since it can't, make it not easy.) For example, if there are 100 participants, they can add 100 more and save 50% of the money.

I insist on at least 12 to 24 hours.

I am okay with using the hash of the next block and the succeeding ones. 1. A block number is determined that is the closest to the time of draw (estimate) and published. The website must also contain full details on the method used to determine the winners so anyone can verify the results.
Time of draw = Date when no more entries are allowed and the full final list is published + around 24 hours.
2. Player receives a numbered ticket when he or she completes the specified action like making a bet. (Requires altering the current mechanism)
The numbering is in chronological order. First bet gets ticket 1, second gets ticket 2, and so on.
3. The player is able to view his ticket number and the UTC time at which the bet was placed.
4. The usernames of all players holding tickets to the draw (partly or fully revealed), the corresponding ticket numbers and optionally the time the bet was placed are published and updated periodically.
5. Once the specified block is mined, the last 10 characters are taken and converted from hex to decimal. modulo + 1 will determine the winner of the highest prize. Next ticket will win the next highest prize and so on (I am not sure how many will agree on this, but it has the same effect as any other method of drawing the second and other winners.)
The draw is made, the winners selected, announced and paid.
6. The block number as well as the list of usernames and ticket numbers remain published for 3 months.
Requesting someone to review this.
Note: This is not a 100% provably fair method as such is not possible. This only makes manipulations difficult, not impossible.

Let me know which one you want to implement and the full details, so I can make a provably fair verifier.

What's the latest guys? We want to make this transparent and fair in your eyes. Have we come to an agreement?
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.

Shouldn't you apply modulus (number of tickets)? Why - 1?
Without -1: Range of 0 - # Of Tickets - 1
With -1: Range of 1 - # Of Tickets
Sportsbet.io, have you decided whether you are going to use multiple block hashs, more digits or a combo of both?
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.
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.
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.
Get your idea up there then we'll figure out what to do based on what the community says

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). Jump to:
