its not really a dice game tho.... its just a statistics game... you cant really have a dice with 64,000 sides can you... it would just look like a round ball.
You could just roll one ten-sided die 6,400 times.
Actually, you couldn't. That would result in a normal distribution (in which numbers closer to 32,000 are more probable) instead of a uniform distribution (all numbers equally probable).
You're right. I was typing without thinking. My intent was to roll a die for each decimal digit (which is why I suggested a ten-sided die), but somewhere in the middle of my sentence I lost track of what I meant to suggest and ended up suggesting 6,400 rolls instead of 5 rolls.
To get a random number from 0 to 65,535 (which is what SatoshiDice actually uses, not 64,000) from real dice, you would need five 8-sided dice (or roll one 8-sided die five times) and one 2-sided die (or coin). Roll one for each octal digit, then convert to decimal.
Your suggestion would certainly work. You could also roll a 4 sided die 8 times (once for every pair of bits) and convert to decimal, or you could roll a 20 sided die 4 times (once for each hex digit), and re-roll any value larger than 16.
For those who have difficulty with converting to decimal, you could just roll a 10 sided die 5 times (once for each digit), and discard the result and re-roll if you end up with a number larger than 65,535.
