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

[ndnh]

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. <The resulting number> modulo <the total number of tickets> + 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.

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. I thought of the chained winners originally, but I didn't think many people would like it. It is simpler though.

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

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.

The probability is the same. I am okay with using the hash of the next block and the succeeding ones.

I thought about this point a bit more, and think that chaining is a bad idea now. The reasoning behind this is that they could put 13 tickets in for every 13 real tickets, and guarantee winning half the prizes (with a 50% chance to win the 1 BTC prize). It would be way too easy for them to rig it, knowing it is chained. I think we should use a combo of multiple blocks and different character amounts, so it doesnt take too long.

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.

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.

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 disagree to your disagreement. If you chain the winners (like person 1 wins #1, than person 2 wins 2nd, e.t.c), putting in 13 tickets right after 13 legit tickets were given (at least that was what I meant, I do realize now that it was a bit vauge) and repeating, this will guarantee they win half the prizes. Why? If one of the 13 real ones win, the 13 fake ones will follow after the first 13 prizes. If the fake one will win, they still will win half the prizes, since after the fake ones are over, than the real ones are there. Once the real ones have past, there will be more spots for the fake tickets to win.

If another method is used (without chained winners), sportsbet.io can't guarantee a winner.

I think sportsbet will make the Premier League promotion in every month, after the successful promotions they have made in Euro Cup and Olympic Games. I can say sportsbet is one of the best bitcoin sportsbooks out there!

[dinda22]

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.

[ndnh]

Truly one of the best player friendly sportsbooks out there.

[Apriand]

Thanks Sportsbet.io! Looking forward to the next round!

Grats to all EPL leaderboard winners, too bad I could not manage to on top 50. I was on 37 before the final result but unfortunately I missed some matches last Saturday and Sunday. Cant wait for the other great promotions by sportbets.
Overall, this is my favorite sportbets site so far because it offers many markets and of course many promos
