The dice algorithm needs to be re-written. It is not random. I’m am really fed up with the way that the dice roll. I will not be renewing my membership next year if this keeps up. Is is random when a player gets 4 doubles in a row? It happens repeatedly. I have never rolled more than two at a time in my 60 years of playing. Fix it!!

Yes.

Sorry to say but that means you played with rigged dice the whole 60 years.

Although this is the Yahtzee forum, your previous 6 games as of when I started
this analysis were all Backgammon, so I ran the numbers for that instead.
(If you really meant for Yahtzee, then what _exactly_ do you mean by "doubles"?)

In your previous 6 games as of when I started this analysis, there were
41 , 29 , 44 , 58 , 50 , 56 ​ rolls respectively, for both players combined.
That gives at least ​ 20 , 14 , 22 , 29 , 28 ​ rolls for _each_ player.
The two smallest of those numbers are 14 and 20.


Assuming each roll is of exactly two dice:

When the number of rolls is 20, the probability of at least 3 doubles in a row is between ​ ​ ​ 0.06862 and 0.06863 ​ .
When the number of rolls is 14, the probability of at least 3 doubles in a row is between ​ ​ ​ 0.04650 and 0.04651 ​ .


(1-0.04650)^15 is less than 0.49, so: ​ How many games have you played in your 60 years of this?



https://paste.ee/p/S0l0i has Python code I wrote for the above.
I have not yet made the changes to test 4 doubles in a row, but

the above was for the _smallest_ number of rolls in your 6 most recent games
and
you did not link to even one example of anyone getting 4 doubles in a row

.


(I imagine the natural estimate - that the probability is 1/6 of the probability for 3 doubles
in a row - is less than 25% off from the true value for the above numbers of rolls.)

Thank you for your highly intelligent and condescending reply. You clearly understand statistics, probabilities and computer coding. However, you haven’t learnt any manners, humanity or how to be gracious. Please don’t bother replying. Although I think you would be unable not to.

Because you did it yourself?
Reread your first message and tell me yes.

I knew you could not resist. It is beyond you not too,

these dice threads rarely dissappoint

They're not random at all

That's correct, given that the rolls are computer generated, the rolls are pseudo-random.

That said a (relatively short) sequence of rolls will often appear not to be random to the observer - generally because the observed sequence isn't long enough.

Again I continued to be surprised that those who believe that the die rolling is rigged against them a) continue to play & b) continue to complain about it.

Right, but I meant the threads.
