I just played through over 50 backgammon games without even 1 double roll. Am I just unlucky or is the random dice generator not doing such a good job?

Czuch Chuckers: Maybe you are falling in love :)

Czuch Chuckers: I just went through all the games you have played this year and you rolled doubles in every single one of them.

It depends on the length your games had (match length and game length).
For example for 50 1-point/single games of a short 20 moves per game(that means i've taken the best case so your case would have even less probability) the probability of not having a single double is:
(5/6)^(50·20) = 6.5 E-78 %
That means a 100% FLAW on dice generator!!!!!

But i guess you are overreacting and that "50" and "NO double at all" is not correct....


PS: To give a feeling of what 6.5 E-78 % is:
6.5 E-78 % = 0.000000000....another 65 zeros....00065 %

Pedro Martínez: lol.... I meant that I moved one move in 50 different games without a double roll....

Pedro: You checked tham all?

Matarilevich; Yep, and I believe her name's Babygirlle.

Czuch Chuckers: Oh that means a probebility of:
(5/6)^50 = 0.011 % Not so unlikely.....:-)

Pythagoras: So 1 double in 50 rolls is not unlikely?

Pythagoras: Yep, it's a one in 9100 chance - an everyday kind of occurence.

playBunny: Babygirlle?? But she is very young for C.C.

Czuch:

I stopped looking after finding these 4. Your last move in each is a double.

Matarilevich: No such thing!

playBunny: Maybe he meant he didn't have 50 doubles in his last 50 moves?!? LOL!

Pythagoras: I guess so too! LOL...what a bad luck...

playBunny: hat first link, that was doubles for my opponent, the second link, I havent made a move in that game yet today, I havent looked at the other two yet. Since I posted the first time, I now have rolled 2 doubles today.

Pythagoras: LOL

Matarilevich: She be past the age of majority plus a little bit more.

Czuch: Eh? The first link is a pass for your opponent, janka/Amálka, and a 4-4 for you (move #21). The second is a pass for CindyTN and a 4-4 for you (move #9)! Have another beer, mate.

playBunny: Yes, the third link you posted was a move made today after my first post, and the fourth link that was not a move I made today as well. Nice try though....

playBunny: Okay, but only one of those was a move I made today, and that one was after my first post on the subject, and I am not drinking quite yet today!

Czuch: Then I'm not sure what you mean by 50 different games. You've only got 51 games and 8 of them aren't Backgammon and now it turns out you haven't moved in a number of others, so... I'm lost. What are you saying happened?

playBunny: Okay, my first 50 moves today in backgammon games I didnt roll any doubles.... that is what I meant to say! I now have rolled 3 doubles since then.

Czuch: I'm slow today but now I gotcha. Don't mind me, I'm from sleep deprivation, lol.

And it's a 9100 to 1 happening, so pretty wierd indeed. ;-)

playBunny: But it would happen quite often if 100 people play 500 moves a day (once a week or so).

ShunAyumiTaiki: The player from the list of blocked users cannot:
* invite you to a game,
* see you on Who is online page,
* send you a message,
* add you to their Friends list
but i am not sure of he can not write you a message into the started game. Maybe someone can help you about this doubt.

This is the backgammon board, lets try to keep our heated discussions on how the dice cheat people. :-)

I have removed all the off-topic posts - please do not be offended if I removed one of yours even if you were trying to help, but they did not make much since once I removed the original posts. I left Matarilevich's post below since it is very good advice for anyone that is having a problem with another user to place them on their Blocked users list.

Plus if you have someone as a blocked users, you will no longer see in-game chat from the person. (They can continue to write and think they are writting to you, but you will no longer have to read it.)

Thanks.

BIG BAD WOLF: Thanks BBW :)

Matarilevich:

I would a bit correct the aforementioned like this:

A person that is on you list of blocked users as Person-A cannot:
* invite you to a game using the Person-A profile,
* see you on Who is online page using the Person-A profile,
* send you a message using the Person-A profile,
* add you to their Friends list using the Person-A profile.

>but i am not sure of he can not write you a message into the started game. Maybe someone can help you about this doubt.

He can't write you any message on an already started game using the Person-A profile....

BIG BAD WOLF: I think you need to try again LOL

Pythagoras: Are you suggesting that only Type A personalities can be blocked? ;-)

alanback:

And there's very possibly a correlation in that idea.

Pythagorus: As BBW said: "They can continue to write and think they are writing to you, but you will no longer have to read it.". I tested this by blocking a friend in a game just now. All the messages - his and mine - disappeared and then reappeared when I unblocked him. Presumably, then, the offending diatribe plus any additionas will be in the game record for such time as the writer is unblocked.

playBunny: So every blocked player is a Pandora's box of vituperation waiting to be unleashed . . . reminds me of something one of my partners once said: "One day the sky will be black with chickens coming home to roost!"

alanback: LOL. That's funny!

XUG?????

I was at 2250, and in 13th position about a month ago, now I am at 2115!!!!!!

What happened?????

Czuch Chuckers: This happened:
http://brainking.com/cz/BKRGraph?df=14&mf=1&yf=2006&dt=21&mt=1&yt=2006&submit=Odeslat&u=5745&tp=23

Czuch Chuckers: According to your rating graph, your peak rating was 2232.

Czuch: "What happened?????"

You played the last month in a dream and didn't notice all those "Your opponent has moved all their pieces out" messages.

playBunny: I guess I am wondering what I am doing differently..... How have I gone so awry?

2102 now! Stop the free fall!!!!

Czuch Chuckers: It depends from you your opponents and the dice.....Such distribution is normal.
I've dug out some results from me against Jellyfish (5-point matches). Here are the results (1=win for me , 0=lose for me):
1011000110111011100100111111111010111011101


01011000000011011001001110101101 101001 = 48/80 = 60%
As you may see i have series of 9 matches won and series of 7 mathes lost. That is normal.....

An easy way to stop the free fall is to stop playing for a while so the graph would stop look like a free fall....

Czuch: It's hard to know if the free fall is due to the runs of luck that Pythagoras was referring to or whether it's a change in your playing. Certainly stress will make me play badly (and it even seems to affect my luck somehow). Sometimes these things happen because you get a set of games which are exploring new territory so you go down because you're making mistakes, but you learn from them and are better in the future. Have a look at the graphs of other players and you'll see similar patterns. Alanback, for instance. His skill cannot be doubted but he has the ocassional bad patch followed by a climb back to glory..

playBunny: Yeah... Imthink part of it is the two game stair matches I play, for one example. I end up losing 14 bkr points in a draw against a low rated player, or even worse if I happen to lose both games!

I have to be like you, and become more discriminating in the kinds of games I accept and play!

Czuch: Yep, I won't play singles when they are so unfairly rated. That's one part of the solution. Another part is to make fewer mistakes.

Czuch Chuckers: Since the cube came in my hyper rating has skyrocketted, which supports the view that single games are too much about luck. If you want a fairer rating play at least 5 point cube matches.

grenv: Maybe I was just over rated and the cube has exposed my poor play....

2095 now....

When you meet our new year, tell it a hello from me..... Oh and while passing from 2010 tell me who will win the football world cup then.....

but don't tell me i want to enjoy watching it

Pythagoras: Well... the 2096 world cup winner will be the US, but I dont think will be visiting the new year, thank you.

Czuch Chuckers: There will be no World Cup in 2096, LOL.

Pedro Martínez: I believe that was the point. The U.S was planning to hold their own cup between their A and B teams and call the winner the world champion. Oh, wait, they already do that in some sports.
