I would like to know why they dont allow us to play free, and they control the dice roll..

I fully agree with the comment, and don´t understand either...

Only been using the site a few months, been up to a ranking of 300 plus a few times, but each time I do I know now that my ranking will plummet back down to close to zero no matter how I play, no matter who I play against.

Got to the point where it's beyond laughable to predictably tiresome.

Only reason I continue to keep coming back is that afte playing on here, when you play elsewhere it's like having a huge handicap lifted and it tends to raise your game.

I do very much agree: But I think we have to be more specific on the critic! - I have made a thread recently where I am makin´some calculations on the matter. 6-6 f.ex. and the amount of odd dices with less than 1% possibility to happen. In my mind there is no question, that the dices are manipulated and the randomisation stinks! ...

The more 6-6 (and odd dices) - the more strange games with random winners - the more the weaker players will winn - the more encouraged they will be - the more players will garther - the more commercials the siteowners will sell!!!

But I would like a game with real ramdomisation! Or else I cannot calculate... And so the game will be of no interest! What about you guys?

The dice appear to be getting worse. Three doubles in a row is now common.

The program follows the moves, how many times does 6/1 come up when the 7 point has a single on?, if you play the percentage move then you may be ok but if you look at the next throw you would have been hit if you hadn't, it would be so good to have dice you trusted, we all know that they are cruel mistresses but these are twisted as well.

And 3 doubles is: 1/36^3*6 = 0,00128 = app. 1 out of 1000. f there is app. 25 throwes for each player in a game (it´s high!) - it is 1/20 of all games, you will sea triple. If it happens every 10 games it is the 100% more, than expected!! ... And that´s is what we are talkin´about! **** randomisation... Cheat is what it is!

If you think that getting three doubles in a row has a probability of 0,00128 then it is no wonder that you feel that 3 doubles are coming too frequent.

(hint: the probability of getting three doubles in a row is much higher)

Thank you.

Well, well, well: So there is in fact somebody with contact to the owners of this site at the end of this conversation! Very interesting: - I will like to express my thankfullness for your contribution, my friend!

Nevertheless: If your statement shall have some impact on me, I`m afraid I have to see it proven... Or else I would not know if you´re just another fool - right?.. I myself is no mathproffessor: But I have written 2 or 3 books about BG (ex: Paul Lampford: Improve your Backgammon) and I´m familiar to the sample space of 2 dices. I would very much like to watch you do the math ... So go on my friend!

Regards

So sad: But really no wonder!! ...

If there is someone clever at the other side of this curtain: Please come on out in the clear sun to tell us fools, how a real BGshark is doing the math... or else it will have no impact on us: - whether you tell us, the moon is made of green cheese or you tell us it is rather common to get a double 3 times in a row!!

On any turn, the probability of rolling a double is 6/36 = 1/6. Each roll of the dice is independent.

So the probability that any given turn will result in the rolling of doubles three times in a row is (1/6) x (1/6) x (1/6) = 1/216. This is approximately 0.46%.

Which is roughly 3.5 times as frequent as your mentioned 0.128%.

I hope this answers your questions.

Thanks for your participation, mister "Flyordie"

I had both a subject and aim by writing. Fist of all you misunderstood the subject. The aim we can discuss later, when we have solved the math conclusion: Hope that´s all right?

You right in: The sample space is 36. Therefore the probability of getting a double is 6/36 in that there is 6 different doubles: 1-1, 2-2, 3-3, 4-4, 5-5, 6-6.

You´re subject was: The probability of getting 3 RANDOM doubles in a row:

This is like you quoted: 1/6*1/6*1/6 = 1/216 =appr: 0,5%
ex: 2-2, 3-3, 5-5 or 1-1, 2-2, 1-1

My subject was: The probability of getting 3 OF THE SAME doubles in a row:

This is like I quoted: 1/6*1/36*1/36=1/7776= appr: 0,01%
ex: 1-1, 1-1, 1-1 or 2-2, 2-2, 2-2

1/6 because the fist doble can be any double
1/36 because after "choosen" a double the next shall be the same... and the next again the same

Let´s have an aggrement on this first of all, can we?

Yours BGdude

No, you were talking about:
"And 3 doubles is: 1/36^3*6 = 0,00128 = app. "

you have not mentioned you were talking about three same doubles.

OK, now we have the probabilities. Now it's just about time you show some evidence of your accusations. Show me that three same doubles happen more frequently than it is expected, please. If it happens so frequently, it would not be too hard to prove it, would it.

Thank you.

Sure I will: If you let my have access to my last 256 games I will show you, that 3 times in a row of the same double has happened not 1 time - but 3-5 times in that period of games (should be one time out af 256 games, if a game is about approx. 30 throwes with a dice).

The reason is - I think- , that there is a lot more doubles on this site than the statistic amount of 1/6. I haven´t done counting on that issue lately, but did so 1-2 years ago where I examined the amonunt of 6-6 over 2 times 2000 throwes. -And found out, that in both observations the amount was more than the double = 2/36 - 4/36 ... Specially in situations closed out there seemed to be a significant difference.

But one thing at a time: Let`s start the proces allowing me to have acces to the last 256 games, I have played and let´s se what statistics we can make out of this... 7776 throwes should be enough to apply to the "law of big numbers"...
