The way the scores are calculated are discussed in another post titled "ELO Rating". As for the rules, the only ones that may not be too obvious are that you only get additional dice based on the largest number of CONNECTED territories you have, not just the total number of territories you have, and that you can store up to 32 additional dice once all your territories have reached the max number of 8 on them (the number in reserve is shown under your name, e.g. 40+14 where 40 is the number of dice you have on the board, and 14 is the amount in reserve). Hope that clears some things up.

More on ELO rating:

Before a game starts the kdice server calculates everyones expected score based on thier rating. So suppose you have players ratings as follows:

R1=20
R2=0
R3=100
R4=200
R5=75
R6=100
R7=0

To calculate the expected position of player 1 the following equation is used:

EP1 = 0
for each player rating Rn
EP1 += 1/(1+pow(10,(Rn-R1)/400))

EP1 is now a value between 0 and 7 representing the estimated finishing place.

When the player finishes a new rating is cacluated based on the actual finishing position A.

R1 = R1+(32*(A1-EP1)),0);
