people look at this game and tell me if it is not a game impossible ...

Those are very frustrating but happen frequently when you can`t get in a 3 or 4 pt board. I have many like that. Take a look at this game starting from roll 28 and think yours was impossible. Look the way it was played and how many hits missed and with the board I had one hit means the game.

pip count was 75-73 when this started. I rolled 2-1 2-1 5-1 4-1 4-3 2-2 3-1 4-1 5-1 and lost by 5 men. 9 rolls in this sequence for a total of 47 pips with 7 rolls out of 9 with a 1. happened in a few other games. not very random numbers.

How is it that those dice are not random?

That's exactly my point. CharmedOnes says 'not very random numbers' for the dice, so my question is that how is it that the sequence of dice is not random?

Of course there is no way to know from a sequence of 9 rolls whether they are random. We know this sequence is very unlikely, but unlikely events are not impossible and therefore do happen. To argue that there is a problem with the ZE dice, someone has to systematically study their rolls and show that over, say, a thousand rolls some event is happening much more often than probability would predict. In responding to a different thread, I looked at nearly 1000 rolls from my games and everything came up exactly as you'd expect. I did not, however, look at specific situations, such as whether consecutive double 6's are more likely to happen than they should when someone is bearing off. Until someone does that study, I accept the complaints about nonrandom dice as frustration about losing a game you'd win 999 out of a 1000 times. I know I have those frustrations frequently.

(By the way, would you say the dice were not random if those last nine rolls had been, say, 2-1 2-1 5-4 6-3 4-3 2-2 3-1 6-3 5-4? That sequence is just as probable as the sequence that was rolled by CharmedOnes. It's the same probability for any sequence of 9 rolls that has one double, three rolls done twice, and two other rolls. in other words, once you rolled 2-1 2-1, having two of the next 7 rolls be 5-4 is just as likely as having two of them be 5-1.)

Good points but those have every number in them almost an equal number of times. Big difference to 9 rolls without a 6 and 7 of those rolls with a 1 in it. This is actually random but a sequence very unusual and emphasized anytime in a game but especially in a race. You would lose many races with a big lead with all those ones with an even bare off board.

A future sequence of repeating number(s) may seem a remote possibility and Probability invites us to see it that way before events occur. ... Yet it tells us that any number is as likely as any other to come up on the next roll.
Past events cannot determine future outcomes; or as "they say" in Craps, "Dice have no memory". We like to think that the "Odds" are 5 to 1 Against ANY number coming up next, but really Spots can't see around corners, so that One number does not even know it has 5 competitors. And it does not seem unfair to think "Probability" might exist only to give everyone a great Wind-us-up; . . . if it existed at all.
But ultimately, it s only a convenient fiction, since we might as well say ' Nothing is ever Random' since only what happens can happen, and the Probability of that is always 100%.

how about this one for fun and not yet done---http://zooescape.com/backgammon.pl?v=200&gid=225929

both have 5 pt boards --he needs to get 4 men past my 5 pt abord adn I need to get one in his 5 pt oard--I stay off 20 rolls while he gets 3 out and may yet win this since it is nt over--incredible and against all odds--I ahve much better chance to get in and out with one man --but 20 rolls later not yet in.
