Sample interpretation of the last data above (three vs. two). If an attacker starts with 1000 armies and a defender starts with 1000 armies and a 3 vs. 2 attack is ensued, the results should be (given fair dice): after 100 rolls, each side will have lost 1 army about 34 times. The defender will have lost 2 armies about 37 times, and the attacker will have lost 2 armies 29 times. Therefore, after 100 rolls, the attacker should have 908 armies left, and the defender should have 892 armies left.
Conclusion: heads up with three dice versus 2 dice, the attacker has an advantage in the long run. Similar interpretations can be made for the remainder of the data, which can be summarized as follows:
Attacker 1 versus defender 1: defender has the advantage, winning about 4 out of 7 battles
Attacker 2 versus defender 1: attacker has the advantage, winning about 4 out of 7 battles
Attacker 3 versus defender 1: attacker has the advantage, winning about 2 out of 3 battles
Attacker 1 versus defender 2: defender has the advantage, winning about 3 out of 4 battles
Attacker 2 versus defender 2: defender has the advantage, winning about 3 out of 5 battles
Attacker 3 versus defender 2: attacker has the advantage, but the advantage is much more narrow than any of the battles described above. The attacker's advantage is such that he will win about 7 out of 13 battles on average.

Checking the numbers you can see this is the actual probability. However, actual results may/may not differ since probability is the "chance of happening" and thus doesn't necessarily state that it will/will not happen. However, on a very large sample space, you will get the posted results.

1st
I am not sure that it really has any benefits to be honest mate ...
I find the data to be mildly 'interesting' (not cleavage interesting .. let's say as interesting as finding a heart-shaped potato-crisp in a packet.) as it roughly confirms probability.
But I find that the format which displays data of possible rolls to border on pointlessness. (no offense intended to the creator.. great work!)
The analyser does not project percentage of probable success, it gives a best case result... an ideal.. and a worst case for both attacker and defender...
perhaps i am not using it correctly and someone else can instruct in its better usage but i find it a clumsy tool (which was incidentally my nickname at school)
Does the CC dice randomizer actually adhere to these probabilities? As an attacker it seems like I almost always suffer more casualties than the defense in 3 dice to 2 battles. Enough so that the game is becoming a major drag. I really don't think its just my stilted perception at work either.

thats thing... with probability you can never be sure

For the 'I don't know how manyith' time.. random.org. The dice come from there, check them for randomness if you want.
Now that I have somebodys attention.
The dice come from random org correct ?
Now is it one set of dice used by all players?
If so then there lies the reason behind the bad luck.
So now ask why I come to this conclusion.
or just post you reason.

Why bother to post if you only have negative crap to spew.
Oh I forgot your mouth and your ass discharge the the same stuff.
Why don't you get a life, I would say CC is more like risk than you think or did lack just think this up by himself?
I found out why the dice are messed up , and wanted to confirm it by asking a few question's and see what response to them I got.
I really don't care one way or the other if they work or not, but from a lot of the posts I have read seems that some do care.
And by the way for a guy that joined in October you talk alot but seem to be not winning many games or don't you know how to play?
Aight, i might be new at this, but at least im smart enough to know when i got burned. So, all i can say, is im sorry i dissed your thread. I am not even sure why i did it, it just seemed like a right thing to say at the time. And about my wining record, i ahve only been playing for a week, and i got my premium the same day, so you can imagine how a noob reacts when he gets a chance to play unlimited games. I signed up to like 20 games at the same time, and without thinking straight , just lost all of them. So, again, sorry for the little display of my annoying side, and keep up the good work with your dice mission
Sorry about that but All I want to find out where dice come from and is it from 1 set or multi sets of them.
Will explain theory in a bit but would like to have more input on my question.
One part was answered the random.org part now need to know how many sets and are they exclusive to CC.
As for loosing games It's all part of the learning process, not like playing a board game where moves are right away.
With the 24 hour time limit people get impatient and need to make a move quick, hence the 20 games at the same time.
I figured if I could shed some light on it then we would have less post's on the dice.

even though your thread is doing a lot of good for those who care to read it, those who dont ( which is the majority of CC population ) will just ignore whatever you are trying to explain and will keep on pushing their shit. So, you are pretty much doing this for yourself and those few that care. But, and i hope, i might be wrong.
